My RB25DET S13 development

[Jeremy 200]

Thought id better put a few pics up of the car since its been off the road since June 07. Basically the old CA had enough and i decided to take it the next step instead of replacing it with another.

Had the car back about 2 months and just been running it in when i have had time and doing some tweeks here and there including fitting an Apex half roll cage.

Basic spec of engine is:

RB25DET
-Fully rebuilt
-New Nissan Oil pump
-New Nissan Water pump
-ACL race bearings
-ARC head studs
-Garrett GT3040R dual BB Turbocharger with anti-surge housing
-Cometic 1.3mm metal head gasket
-New rings and seals
-Nissan complete engine gasket kit
-Greddy timing belt
-SARD 630cc injectors
-KU Engineering Top feed fuel rail
-KU Engineering inlet plenum
-KU Engineering 90mm throttle body
-Bumper mounted Intercooler
-Nissan Z32 AFM
-Nissan Z32 fuel filter
-Apexi Air filter
-Apexi Power FC mappable ECU
-Apex oil cooler kit
-Custom dual core radiator
-Twin 12 inch fans
-Walbro High Flow fuel pump NOW Bosch 044 fuel pump (in tank)
-Greddy profec B boost controller
-Custom made exhaust 3" from turbo back
-DW Wasted spark ignition. NOW running Splitfire coilpacks

Yet to be mapped so running about 10psi at the moment with a 6k rev limit. Loving the engine though, so smooth throughout and revs beautifully too and sounds :smitten:

Got one video of the 1st start and drive here too:
http://www.youtube.com/watch?v=gJ9zjkJ5Pc4

All the work was done by Stu (Stuee_69 on here). Most will know him by his mental RB30DETT S13 which he put together himself. Massive thanks to him for all his work on the engine as i made his life pretty difficult by buying a turbo that is too big for the mani and a gigantic inlet manifold that was a total PIA to fit. So many other things along the way too like having to make up a new injector loom for the top-feed conversion...the list goes on!

very nice mate :thumbs:

[pdh 14a]

Some hard work gone into that! looks awesome :notworthy:thumbs:

[BWanderers]

Not my thAng at all, (Preff street sleeeeepr:sleep:)

BUT lUURVVly any way

Best of Good Work!

Rob.

[Robdriftit]

that looks very good mate :) any guess on possible power figures yet?

[BigD]

mmmmmmmm looks great :D

[Jeremy 200]

that looks very good mate :) any guess on possible power figures yet?

Thanks guys:)

Power wise the turbo is rated to just under 600hp but as the engine is fairly std. id like to keep it under 500hp ultimately. So i guess id be happy with about 450:D

[Ken]

Looks great Jez, was nice to have a quick nose around it today at the Chessy meet

[schumi84]

Indeed, looks fantastic mate, was glad i was there to see it in the flesh.

Good luck with the mapping and dyno run :thumbs:

[Mario]

Looks and sounds amazing Jeremy.

Enjoy!

[DREAD13]

Very nice, i must say sir!! :)

[gonzomagic]

Thats lovely, well done.

Would love to see how that was to drive.

[200jim]

very smart alot of time gone in to that

[Paulpen]

Nice car and nice site too :thumbs:

Any link to where you got the inlet manifold from ?

this is the inlet mani. KN Engineering. Was a VERY tight fit with the master cylinder!

[s13silvia]

crikey that looks perfect mate, stunning job!

[mav]

Damn thats tidy, nice work mate :thumbs:

[Ron Bones]

Awesome that is! The Rb looks right at home in there, really tidy. Congratulations!! :clap:

[Si]

Such a tidy looking and thoughtfully specced car dude, cracking work - there are some awesome cars around right now :cool:

[tokyo_black]

That is gorgeous!

[Shirunai]

niiiiiiice but dont raise the bonnet, it will make it even hotter inside the enginebay when driving, belive it or not.

[Jeremy 200]

niiiiiiice but dont raise the bonnet, it will make it even hotter inside the enginebay when driving, belive it or not.

well thats a matter of opinion fella! I have found the water temps stay under 90 all the time since i raised the bonnet. In traffic or at standstill you can see the heat haze coming out of the gap:) I rarely need to use the 2nd fan now.

[Delboy]

niiiiiiice but dont raise the bonnet, it will make it even hotter inside the enginebay when driving, belive it or not.

That is actually total toilet mate. Like Jez I raised the bonnet on the Sileighty and noticed a huge difference in under bonnet temps (not just on stand still but also during 'spirited' driving). I understand all the various theories behind why it might make it hotter but in practice it DOES cool things down under there :nod:

Anyway, back to topic...

Jez, glad you finally got some pics up mate!! The car does look great, so much road presence when you see it out and about and the sound is just :smitten:

Definately worth the wait/effort/money :thumbs:

Looking forward to a spin when it's all mapped and meeting it's potential :nod:

[Parker]

Top car :nod:

[SteveSadler]

looking forward to catching up again and also tuning the engine for you J.

looks nice man.

:)

when you popping over? Stuee ready for his also?

Hey Steve, am very much looking forward to getting it mapped as well! Still got a slight problem with the wastegate arm but it seems to working fine at the moment @ 10psi. Stu's car is still sat in his garage, i think its all ready to go again but i know he hasn't renewed his insurance yet as he's been so busy on other cars, house stuff and work!

Did you want to do some on road mapping first or straight onto dyno?

[SteveSadler]

from personal experience ideally both mate (imperative as always) u know me. ;)

All you need to do it get to my place as per usual n then Job done! :)

Times moved on since .... Was going through my blog...
http://fctuning.com/Nissan_CA18DET4/Tech_Spec.html

Conversion looks real sweet mate. All the hard work n time has payed off.

When you say slight wastegate arm problem, be a little more specific? why have you n stuee had to move it in some way?

Yeah, alot of things changed since then! Time flies...that was back in early 06 i think!!

Well the problem seems to be the wastegate arm is sticking sometimes. If you take off the actuator arm and move the wastegate arm it moves freely open and closed sometimes but then sticks and needs a bit of 'jiggling' to get it work again. Quite odd! Really need to get it up in the air again and remove the downpipe to have a look at the back of the turbo but Stu's been so busy we haven't had a chance.

[SteveSadler]

had a couple of sticking wastegate over the last few months (funny enuff on RB25DET's also one with GT3037 HKS (but then the HKS wastegate that comes with that is absolute crap. Why HKS put that puny thing on is beyond me. Ended up chatting with Owen Developments and replacing it for my mates turbo) Getting that on the dyno thurs. Pop down if your around. il be there around 7.30pm for an hour

Let hope yours aint too bad. sounds like its just a little temperamental . You still need to check it though.

[Jeremy 200]

Thought id add some background and build info for the new drivetrain:

Old engine, forged ND engine with GT2871R producing 365bhp:
http://img.photobucket.com/albums/hh91/Jez_RB/RB/bay.jpg

New engine as it arrived:
http://img.photobucket.com/albums/hh91/Jez_RB/RB/DSC00498.jpg

Cylinder head:
http://img.photobucket.com/albums/hh91/Jez_RB/RB/PICT6945.jpg
After strip down the bottom end looked in great condition with no visable wear on the crank. The pistons and con-rods were also fine and we intended to just clean up and de-coke the pistons. The top end was a bit worse for wear and had signs of overheating in the past. This was later confirmed when it went to a machine shop and they found the head was slightly warped. A skim and re-build later it was as good as new!:)
http://img.photobucket.com/albums/hh91/Jez_RB/RB/PICT7265.jpg

Engine bay before:
http://img.photobucket.com/albums/v124/Jeremy200/RB/DSC005291.jpg
Gave it a clean up and paint with Hammerite before fitting the RB
During:
http://img.photobucket.com/albums/hh91/Jez_RB/RB/DSC00597.jpg

The rebuild of the engine went pretty smoothly.
Here we have the bottom end built up with all new bearings, new oil and water pumps and cleaned up pistons.

1st major problem!:

Second major problem was the clutch master cylinder:
http://img.photobucket.com/albums/hh91/Jez_RB/RB/PICT7412.jpg

This was solved by "massaging" the back of the plenum slightly and taking some material off the end of the master cylinder to match the curve of the plenum

Making up a new injector wiring loom incorporating the GTR resistor (as we switched to tope-feed injectors)
In place on the engine:

New clutch & lightweight flywheel:

http://img.photobucket.com/albums/hh91/Jez_RB/RB/SNV30913.jpg

As no downpipe was available for my turbo we had to make one up from just the turbo exhaust flange and my old downpipe! This is it 'work in progress':

Next few weeks after was spent finishing off little bits and pieces. Not had any problems so far (touch wood:D) so this pretty much takes me to the beginning of this thread.:)

[SteveSadler]

hope you kept a pattern of the pipework as my RB is lying in my buddies garage and iveo got he same plenum coming. :)

great stuff

[mushtafa]

Fantastic work mate, looks very nice. Would love to do something like this. How long did the project take?

[schumi84]

After seeing the progress from then till now, and seeing the car up close it makes it all the more impressive.

Excellent work again sir, will no doubt see you again at another of the Chessie meets.

[Jeremy 200]

Errrrr, yes...maybe....hmmm:wack: To be honest we kind of just made it up as we went along!:D lol Awsome! you got the same plenum! Did you go for the 90 or 100mm TB?:cool:



Fantastic work mate, looks very nice. Would love to do something like this. How long did the project take?

Took just over a year really. Spent alot of time gathering parts and deciding what to do before we started. If you had everything to hand it would, of course, take alot shorter...plus we were working on it mostly at weekends.:)

Yes, i thought id put up the WIP pics as the finished ones make it look like it was just a 'drop in conversion'! lol

Oh yeah and hopefully will be mapped and ready to give some passenger rides!:D

[Paulpen]

Dont suppose you have a pic of the work done to the inlet and clutch cyl to make it fit ? :)

zomg you must take me for a ride :D

[mdub]

the car and engine are stunning, really impressive,

but lose the bodging tape, go through demon tweaks and get some decent cable seperators...

[Jeremy 200]

zomg you must take me for a ride :D

no probs mate. Once its mapped passanger rides will commence:D

Tell you what, i'll put them on....if you buy em for me:wack:

[Jules200]

Hi Buddy:)


I said it all before mate, that a work of art and well done to you,stuee and steve for getting it like it is now:thumbs:.
Now one day i will not be working when you want to come over, shame the rear seats are out as im sure baby Jayden would love the rb experience:eek:.

Take it easy bud and see you soon for a few sherberts:thumbs:....jules

[pete shrimp]

That looks awesome, really nicely done!! :cool:

[Jeremy 200]

Cheers Pete:)

Jules..I'll see you soon matey!

[Mark]

Good work mate :thumbs:

[Jeremy 200]

Cheers Mark and thanks for moving the thread for me:)

Latest progress has been giving the car a base map:

Went up to see Steve from FCtuning.com today to do some basic mapping on my engine as it is running an old map (Power FC) from the last car it was on (Brens Skyline).

We did a little on road mapping on the way to the dyno and then finished the rest off once their. My fuelling is really lacking, with just a walboro fuel pump and adjustable regulator feeding my twin inlet fuel rail and 630cc injectors.

At just over 1 bar boost its making 444bhp @ 7200rpm.


I have to upgrade the fueling before i can go any more but unfortunately my gearbox (which was of dubious quality to start with) doesnt seem to be happy and is very noisey in 1st and 2nd and when idling and pulling away....So thats the first thing to replace!

Its just relentless on the road in 3rd 4th and 5th, power throughout the rev range and top end especially just wants to go and go! I want to go and drive it more but worried about getting stranded with a broken box!! lol

[arry]

great result :thumbs:

Shame about the box - hope you get one sorted :)

[SteveSadler]

how did it feel in 1st n 2nd, did you actually try a take off or did you not risk it? ;-) Once we sort the fuelling (minor prob and something to expected) issue then get it back to me for street & dyno tuning and you'll be done. :)

No didnt risk 1st and 2nd!!:wack: The box was sounding like a bag of spanners at idle by the time i got back! 3rd was awsome though...It pulls so hard all the way to the rev limit and wants to keep going!:D

Thanks Arry, they seem to be hard to come by at the mo. Ebay has loads of GTR boxes but no GTST ones:( Skyline boards dont seem to have much in the way of private sales. I know buying one from a trader is going to be pricey.

They always seem to go as part of the "engine conversion" package now :(

[Jeremy 200]

Yes, so many people buying them to swap into S bodies!:D

Ah well, i can't afford one till after xmas anyway so will have to start searching again then.

[Gary@APT]

jeremy,id say you'd make much more power if they could have stopped the wheel spin the cars has on the dyno...

when we did brens it took a while to strap it right to give no slip

[SteveSadler]

No didnt risk 1st and 2nd!!:wack: The box was sounding like a bag of spanners at idle by the time i got back! 3rd was awsome though...It pulls so hard all the way to the rev limit and wants to keep going!:D


I dont blame you for not trying. just go easy till you can source another box. it wasnt worth me pushing anymore. there is always next time anyway once you've sorted the pump out.

[SteveSadler]

jeremy,id say you'd make much more power if they could have stopped the wheel spin the cars has on the dyno...

when we did brens it took a while to strap it right to give no slip


i was well aware of that Gary ;-) and this was noted and it wasnt the case for all runs ;-) yes, maybe he could have tried a few different options

In all fairness to the chap that strapped it down, yes, It is possibly a marginally higher calculated horsepower figure, however this exercise was simply to get the car into a road worthy running state so as I know what im working with ready for next time. Plus we had issues with his exhaust rubbing slightly.

[SteveSadler]

still, 440 odd hp is more than enough in a stripped out S13 for the state your gearbox is in Jeremy.

[Jeremy 200]

Yeah was a bit of a pain as any tighter on the straps and the exhaust was rubbing & vibrating on the dyno quite badly. Will see if i can add another exhaust mount in to pull it up a bit for the next session:)

More than happy though considering im supplying that big old lump of an engine with a tired little Walboro pump!
:)

[Gary@APT]

watching the vid you can hear a misfire issue, that could be the drop in power at end of run.

ive had a issue with the dw system you running on one we mapped might be worth checking

[Jeremy 200]

Cheers Gary, yeah Steve expressed concern with one he had mapped in the past with the DW kit. Would have gone for Splitfires but the cost was the deciding factor in the end:eek:

FUeling was deffo a big issue top end. We did as much as we could with the Regulator but there was simply not enough pressure from the pump:(

What did Brens do in the end? 600 i seem to recall? (not that im trying for that:wack:)

[SteveSadler]

watching the vid you can hear a misfire issue, that could be the drop in power at end of run.

ive had a issue with the dw system you running on one we mapped might be worth checking


likewise Gary.

To be frank ive had an issue 70-80% of the DW Wasted Spark Sytems fitted to either SR or RB that ive mapped and set up on the road/dyno (never seen a CA with one so cant really comment but then in decade of Nissan/CA/SR ownership ive never had coil pack isssue, may im lucky i dunno). :(

Not knocking the DW WS Set up or anything, Just my experiences with the 4-5 cars that have had them on. Two of the driftworks BDC Guys actually took theirs off and ended up switching back to Splitfires Direct Ignition System after which any ignition gremlins were solved

Jeremy has been spoken to about this as its something i did mention to him in his build up. Also, id probably have coil lead separators also and not have them taped together, but then this is something he knows he has to do as well.

Work in progress :)

[Gary@APT]

no the car i had was wired in wrong,would run and had done a few events

did you check base timing,was the tdc maker jumping around?

[Gary@APT]

its not running lean its a misfire,sort that and ill bet you'll bring afr down

widebands dont help at all when cars misfire

[SteveSadler]

First thing i always do mate. ALWAYS CHECK TIMING. ;-)

That was what i was initially looking for. TDC Marker ok

[SteveSadler]

its not running lean its a misfire,sort that and ill bet you'll bring afr down

widebands dont help at all when cars misfire

I know. useless in this sense.

[SteveSadler]

Dont worry, we'll get to the bottom of it ;)

[Scotty_s13]

444bhp @1.2bar

Well done Jez very impressive great figures and still more to come..:thumbs:

[gander]

thought i would come check it out. very nice and lots of good work . nice to see it sometime soon.

good to meet ya too

[Jeremy 200]

good to meet ya too

Thanks mate:thumbs:

Good to meet you too, deffo gonna save up for those Splitfires for mine... These DW wasted sparks are giving me too much hassle:(

[M.D.]

Thanks mate:thumbs:

Good to meet you too, deffo gonna save up for those Splitfires for mine... These DW wasted sparks are giving me too much hassle:(

whats giving you hastle about it mate,???

i found them really simple and worked a peach. much better than the coil on plug set up,

444bhp is brilliant power, is that from a standard bottom end and head, or has it got internal work too??

[Jeremy 200]

Was misfiring at high revs on the dyno & occasionally on the road. Now im getting a misfire at mid range. Everything is wired correctly and there are no problems with the timing, plugs, CAS etc..

2 tuners (see above posts) have also had problems with other cars not running properly on them and there's loads of 'problem' posts on DW.

We are going to take them off on Friday and check all the wiring, contact points etc.. then will decide where to go from there!

Oh and all std. engine by the way:) Just re-built with all new bearings and pumps.:) Only internal work is a tiny amount of porting on the head.

[Fake Ben Taylor]

i suspect it will be due to the coilpacks only being oem vauxhaul :) works great on lower powered cars (mds for instance) but cant produce the spark power on higher tuned engines :)

might be worth trying to get a high power msd coilpack before splashing out on the splitfires? :)

its the same theory as behind splitfires being better than oem nissan coils :) theres no reason a wasted spark system should cause a misfire if the coils powerful enough :)

[Jeremy 200]

Well, almost 4 moths later and i've pretty much driven it......


Nowhere!


It's always 1 step forward 2 steps back!:wack: After removing the wasted spark setup and sticking in some (costly!) Splitfire coilpacks plus a new ignition amp the car ran better, although with a bit of missing still but then this was to be expected as it was mapped on the wasted spark setup.

I decided to sort the fueling out a bit more so have just got rid of the tired old Walbro and fitted a Bosch 044 in tank. This has had a big effect as the car is massively overfueling now so needs Mr. Sadler to come and tweek the map a bit;)

Hopefully once Steve has been over the map and adjusted it i will be able to get some driving done! Although i haven't been able to get another gearbox yet (the current one sounds like a bag of spanners:wack:) as the prices on RB25 gearboxes is, in general, stupidly overpriced:rolleyes:

Wo,looks a beast mate:) it will be amazing once its remapped for the new fuelling mods etc:thumbs:

[Delboy]

She's getting there mate :)

All this grief will be worth it when it's done! A bit of mapping, new box and away you go!

[M.D.]

i suspect it will be due to the coilpacks only being oem vauxhaul :) works great on lower powered cars (mds for instance) but cant produce the spark power on higher tuned engines :)

might be worth trying to get a high power msd coilpack before splashing out on the splitfires? :)

its the same theory as behind splitfires being better than oem nissan coils :) theres no reason a wasted spark system should cause a misfire if the coils powerful enough :)


the driftworks s15 uses the same coilpack with no problems at all, and is running 700bhp isnt it???
bon bons chaser also used one and that was over 500bhp.

i have an RB20 ignition amp if thats any good jeremy, it has 7 pins on one side and 6 on the other to answer your question from a while back, ive just found it lol.
they are apparently the most powerful out of all the ignition amps, you will need to get plugs to suit it though as i sold the loom i had

rumour has it they removed them a while back due to 'ahem' issues ;)

[Jeremy 200]

Did some more mapping on the road last night with Steve (thanks for coming down to me:thumbs:) and the whole map pretty much needed changing as it was so different with the Coilpacks on. As a result its much much better, no missing now and totally smooth throughout the rev range, very nice to drive but can feel the turbo is begging to be pushed harder...

Only problem now is i need to upgrade my FPR as i only have a basic FSE power boost type one which is not upto the job. (fueling goes lean after 6200rpm) I want to go for a SARD so any recommendations on where's best to get one let me know!

I also need to run a shorter boost pressure take off to the turbo outlet pipe as its currently routed all the way round to the inlet manifold (from the EBC solanoid) which is causing a slight delay and holding back the boost for a bit longer than it should.

Last job is to get a proper actuator made up. There were none available 'off the shelf' so we made up a 'hybrid' :wack: out of about 3 others!

After that we can get it back on the dyno to finish it off and run some higher boost (currently still around 1.2bar).:)

[SteveSadler]

no worries man. twas a pleasure,

At least your ignition gremlins are sorted and its now smooth as, safe to say that previous set up was no good for your particular application. I bet you Wish you got those propa coils in the 1st place. :)

Sort that reg out, get a propa actuator on there (or go external gate mmmmmm) and shorten the run to the pipes, bring it back, n ill put the icing on the cake

Tell Stuee to gimme a shout when he's ready and we'll do the same with his.

Engine feels much better now though, you have to admit. Get Stuee to drive it as he knows the before and after and can probably give some better feedback.

just emailed you a min ago, but Stu has driven it and was very impressed! ;):D

He was up early this morning sorting out some of the small wiring issues it had, interior light and clock! Really, i think he couldn't wait to take it out and give it a 'test':wack:

[M.D.]

mmm


interesting..


yeah that is acctually, my car starts to blow the spark out at 1.5 bar boost and we put it down to plugs, (NGK BCPR7ES apparently i should be running platinums for my power but i cant justify the extra cost) maybe, just maybe its something to do with the coilpack. altho saying that a guy at the same place as i got my car mapped is also running one over 500bhp with no missing what so ever on a gtr engine

[SteveSadler]

nice. ill give him a bell in a bit. lunch break for me now :)

GTR ignitors are different.

every engine is different

and nothing wrong with ya NGK 7s bud. ive personally used those for years on my engines with no probs. If anything whip em out and gap em to .6, Occasionally i run an 8. Used to run 8's on cossies back in the dayz

[M.D.]

we gapped them to 0.6 while mapping which definately helped, my set up does not run an ignition amp as its directly driven from the ecu.

which is more and more pointing towards the coilpack, im definately not ever going to go back to the coil on plug set up as its too much of a pain in the arse to fit and remove when checking plugs etc, so im going to have a look for a more powerful coil pack that i could replace mine with, or maybe slightly increase the dwell time from the standard 1.9 that the nissan coils use. maybe the driftworks coil pack needs slightly more.

[SteveSadler]

its not THAT much hassle to change em?? you can mount em outta cylinder head and just use leads from the pack to the plug, if ya that bothered ;)

[Actual_Ben_Taylor]

LS1 coils??

Good writeup here, ok its for a KA but the principle is the same...

http://www.ka-t.org/forums/viewtopic.php?t=26234

[M.D.]

right i think ive found something,

basically i believe that the standard nissan dwell settings for the coil pack is wrong for the driftworks coilpack,

the standard dwell setting for the nissan coils is 1.9.
but from looking up on the net i managed to find the coil that drifworks use in there kit,

http://store.summitracing.com/partdetail.asp?autofilter=1&part=ACC-140016&N=700+4294890813+400020+115&autoview=sku

they did not give a coil inductance but i found that ACCEL coils use a 5.3 mH rating so ive used that for the calculator.

and by using the calculator that i got with my megasquirt manual
http://www.megamanual.com/ms2/configure.htm

ive worked out that at 6 amps the dwell should be set to 3.26 mS and not 1.9.

but that is for 6 amps so unless the nissan uses 3.8 amps from the standard coils then the coilpacks are not working correctly on the nissan ecu.

these coils are used on 9 second drag cars in america according to some american sites so i dont think its the coilpack that is the problem.

im just off to find out some more data on the standard nissan ecu and ignition amp

mate what you have found there is an absolute godsend, I'm going to check all my settings as that could definitely help me refine my set up, but then again those settings are ok for the standard coils, may not be OK for the ACCEL coil pack that driftworks sell.

[stiv]

have the same accel coils on my rb and the same problem in high rev's over a bar of boost, doing a lot of reading on dwell and will be doing some testing on the coils as soon as i get a chance:thumbs:

found a nice write up on dwell here (http://www.tonyfoale.com/Articles/Ignition/Ignition.htm)

[Jeremy 200]

Brought my car back home yesterday and it is absolutely brilliant! Stu has done a great job of finishing all the little bits and pieces that needed doing. Since fitting the Coilpacks back in and having it re-mapped it is 10000x better!:D

Ridiculously fast and still only running just over a bar of boost.. Went for a drive with mine and Stu in his RB30 S13 and im sure he had trouble keeping up!;):wack::D

Few pics of it, nice and dirty from some proper use! lol

Also fitted some nice carbon look vinyls to the B-pillars that i had made up. They look really good i think!:) Have got another 3 sets spare if anyone wants a set pm me!

Before Steve can finish the mapping on the dyno i need to get a decent FPR as the one i have isnt correct and leaning out the fuel top end.

Sounds good too:D

cheers:thumbs: likewise with yours mate:)

[TM_S13]

looks pretty good !!
congrats

[Scotty_s13]

Well, almost 4 moths later and i've pretty much driven it......


Nowhere!


It's always 1 step forward 2 steps back!:wack: After removing the wasted spark setup and sticking in some (costly!) Splitfire coilpacks plus a new ignition amp the car ran better, although with a bit of missing still but then this was to be expected as it was mapped on the wasted spark setup.

I decided to sort the fueling out a bit more so have just got rid of the tired old Walbro and fitted a Bosch 044 in tank. This has had a big effect as the car is massively overfueling now so needs Mr. Sadler to come and tweek the map a bit;)

Hopefully once Steve has been over the map and adjusted it i will be able to get some driving done! Although i haven't been able to get another gearbox yet (the current one sounds like a bag of spanners:wack:) as the prices on RB25 gearboxes is, in general, stupidly overpriced:rolleyes:

Should also say thanks to Stu (Stuee_69) for his continued hard work on the car! :)

So the walbro can't cope with the BHP your running then Jez or is it just an upgrade..

[Delboy]

Awesome stuff mate, glad it's all finally putting a smile on your face again, told you it would all be worth it :)

Really must give you a call soon mate, been a while!

[dano]

that is one very nice s13 :nod:

[Jeremy 200]

So the walbro can't cope with the BHP your running then Jez or is it just an upgrade..

Yeah, it ran out of steam on the last dyno session! Couldnt keep up with the demand from the fuel rail.

Cheers Del, give us a bell over easter weekend, let me know how your engine swap goes... Are you still going ahead with it?

[gander]

looking nice. fresh look about it. i see you did away with the ****y spark crap

[Jeremy 200]

looking nice. fresh look about it. i see you did away with the ****y spark crap

Thanks mate, yep, sooo much better now with the Splitfires! Got to get a few bits and pieces sorted before we finish of the mapping on the dyno still.

I'll see you up Santa Pod soon! Been itching to get up there!:) You've been getting some good results i see!:D

[tokyo_black]

This is such a superb s13 :)

[Ian200sx]

Awsome car

[Delboy]

Cheers Del, give us a bell over easter weekend, let me know how your engine swap goes... Are you still going ahead with it?

Sure am mate, mounts arrived today :) May take a drive down to you at some point after it's in and ask for a cheeky spin in yours, not been in it at all since the RB went in!

[Jeremy 200]

excellent! hope it goes well, keep us updated!

Your welcome anytime mate:thumbs:

[JP]

Do you mind me asking what duty cycle your injectors were running at on the Walbro when it ran out of puff? What fuel pressure and what size injectors have you got? Lastly, what's the 044 rated to #L/hr @ #bar fuel pressure?

I'm having fuelling issues running E85 where my 4x 1000cc injectors are running out of puff on a SARD (280L/hr @ 3bar) in-tank pump running @ 4bar of fuel pressure. It's killing me cause I can only get just over 1bar of boost on a 2871R before they run out. :(

I cant quite remember the duty cycle before.. I Think it was around 70%.
They are 630cc SARD injectors running of a twin entry fuel rail. I didnt have a fuel pressure gauge on at the time unfortunately but now it is on it has highlighted that my FPR is not a rising rate as the fuel pressure is not increasing with revs.

Some specs on the 044: http://www.camskill.co.uk/products.php?plid=m10b959s2657p37088&rs=gb

Theres also a big thread on it on here somewhere. Quite a few people running them now.

I would have thought 1000cc injectors should be plenty big enough to cope on your setup.. Sounds like there not getting enough fuel supply, Maybe you need to fit an inline pump as well as the SARD?

[JP]

By inline you mean external? Swirl-pot needed too I'm guessing?

I've a SARD Type-RJ FPR but can't remember what size the ports on it are (6mm or 8mm); what have you got?

Lastly, how many & what type of fuel filter(s) are you using?

Hi mate, yeah, inline pump would be external. Yeah, ideally you'd want a swirl-pot... Maybe you should just try a more powerful intank pump first though?

8mm on mine. I need one of those SARD FPR's! There just what i've been looking at! That and the AEM ones. (which are a bit cheaper)

Just the one fuel filter. Off of a (VW) VR6 engine. Its a bit larger than a 300zx filter.:)

[JP]

The SARD 280L/hr one was the most powerful in-tank one I could find at the time - didn't know about the Bosch 044 but you can use that in-tank anyway can't you?

If the SARD FPR's what you're looking for then I'm hoping mine's an 8mm port on each, haven't checked.

What size is the hole going into that filter & do you just get them from a VW dealer? Do they cost much or do you have a part number?

Yep, you can use the 044 in tank with a filter 'sock' on the bottom of it. Its not too hard to do either.

Should be 8mm.

My lines are 8mm and the fuel filter came from just a local motor factors. Ask for a 2.9 golf/corado VR6 fuel filter:thumbs: cheap too as i recall:)

[JP]

Cheers for that good sir! :thumbs: I'll get out a measuring tape whenever I get a chance & confirm what size the fittings are on the FPR.

[SteveSadler]

Hows the drive ? ;)

Stuee ready yet??

Very good mate!:thumbs: Loving it! Cant wait for some more boooost!! :D

Me and Stu are heading over to castle combe next Sat... Its one of the big 'action days'. Im not going on track but i think Stu wants to.. you should come if your not busy!:)

[SteveSadler]

nice nice!

Sat COULD be a possibility. im not sure yet as i may be busy mapping a couple 200's and a Pulsar on that day but ill check my diary and see. If not ill drive up with one of you (if you've a spare seat ;) )

[Jeremy 200]

After the 'missing wheel' incident a few weeks ago (http://www.sxoc.com/vbb/showthread.php?t=405257&highlight=cheap+nuts) i've not done much with the car as the insurance is up now and id rather take my time and get things done properly before it goes back on the road.

Already got a replacement wheel thanks to Dan at SRB:thumbs: and when i can, they are all going to be powder coated white as i fancy a change:)

Parts im going to order (next week hopefully) are:

- Wide front fenders (+25mm)
- 4 x DW 25mm spacers (rear arches are going to get a roll)
- New brake rotor

and i've got my eye on a vented carbon bonnet too:D

The front bumper got a bit mashed so i thought id have a go at fixing it a bit before it goes to the bodyshop to have the new fenders painted sometime in June.

sweet!, also nice to see a standard rb25 running very healthy figures, mine ran 404.4 at 1.2bar, feel a bit more confident in the engine now knowing they can handle as much.


cars looking good!
