View Full Version : Bubbles R34GTT engine build
I have been so busy the last week, what with running in the new engine, mapping it, new brakes and bedding them in, TAX and MOT, trackday @ Snetterton on Wednesday etc. etc. I have just been too tired to tell all about the new engine etc. Well that is my excuse and I'm sticking to it:D
Anyway, some pictures:

The long awaited grade 5 shells finaly installed, with the balanced bottom end.

I guess we need some pitons now.
http://www.dropshots.com/photos/127158/20070216/b_163325.jpg
Custom made Arias forged pistons, which are more than twice the price of off the shelf R33 RB25DET pistons.

N1 oil and water pumps.
http://www.dropshots.com/photos/127158/20070216/b_163404.jpg
Greddy exhaust manifolds can crack, just like the rest.
http://www.dropshots.com/photos/127158/20070216/b_163408.jpg
Lets see how long that lasts.
http://www.dropshots.com/photos/127158/20070216/b_163338.jpg
Nobody makes a large capacity baffled sump for the NEO engine, so RSP fabricated a 7 litre one for me.

Tomei GTR baffle kit.
http://www.dropshots.com/photos/127158/20070216/b_163416.jpg
Nearly done.
http://www.dropshots.com/photos/127158/20070216/b_163424.jpg
All done and painted. The oil pick up to the oil pump was extended to reach the bottom of the new sump.
http://www.dropshots.com/photos/127158/20070227/b_185706.jpg
In an effort to stop me from keep getting Black flagged at trackdays, the screamer pipe from the Greddy external wastegate has been plumbed back into the exhaust down pipe, with a removable flanged section. When the section is removed for normal road use, the rear flange is blanked off and the front flange from the wastegate has an angled section pointing towards the ground.
http://www.dropshots.com/photos/127158/20070227/b_185723.jpg
I took many hours to design and fabricate the exhaust and sump!
http://www.dropshots.com/photos/127158/20070303/b_124404.jpg
Oh yeah and who said that Greddy plenum couldn't be made to fit the NEO engine? RSP managed it, together with a Q45 throttle body :D
http://www.dropshots.com/photos/127158/20070303/b_124423.jpg
New fuel rail too.
http://www.dropshots.com/photos/127158/20070303/b_124508.jpg
Plenum, throttle body and turbo all polished by our Eddie (ESP)

Just need to replace one or two hoses for Blue ones and then get polishing the engine bay.

looks great, good luck with it matey.
Looking at the n1 waterpump, where you've got the slotted hole with the 10mm bolt going into it, that is a very reknowned point for the waterpump to leak!
When i had mine i filed a penny washer to the right shape and filled the slot with instant gasket to keep it water tight, before that it took 4-5 attempts at faffing about asking advice off people and removing the waterpump, cambelt etc because it kept leaking.
hope that might be of some use :)

that engine is:smitten: :smitten: :smitten: :smitten:
Looks fantastic Geoff, good on you mate:thumbs: (I love the EWG set up, I've got exactly the same thing:thumbs: )
That looks spanking Geoff:nod:
Looking good Geoff - give the outside of the car a clean while you're there!

How severely did you punish any of your work experience boys that dared to look at the engine while it was being built/fitted :wack:
Looks like it was worth the wait. How did the trackday go?

looks good
though you spend all that money and cant put a genuine Nismo oil cap on there lol
I heard the neo's are more stressed than the older RB25's as stock how have you found the tuning route in comparison mate ?

Hi matey... Looks ace.. What fuel rail is that? My friend is after a custom one.

have you got any pics of the whole car?? suppose it goes alright then??
Class work mate :thumbs:
Big up :D
Looks like it was worth the wait. How did the trackday go?
It went fine, but I need a larger oil cooler to keep the temps lower. There is allways something more that you have to do:D

Just looking on Nengun now:p
:D
I heard the neo's are more stressed than the older RB25's as stock how have you found the tuning route in comparison mate ?
The R34 NEO's are a lot harder to source parts for compared to the older R33 RB25DET. Although they produce more power as standard, they have smaller injectors, which soon max out with stage one mods. They do however have GTR rods and solid lifters as standard:thumbs:
Hi matey... Looks ace.. What fuel rail is that? My friend is after a custom one.
It's was one of a batch bought by RSP to fit GTR's, except they didn't, so it was modified to fit mine.

that looks awesome!! :notworthy sorry if i sound dumb, but my knowledge of RB's is a bit :confused: but one thing im sure, an rb25det neo head doesnt look like yours. from what i can see in your pics, looks like you've got an rb25 block with an rb26 head? :confused:

whoops my bad eye sight, it did look quite similar in some ways. probably because of the inlet pipe is not going across the top of the cam cover. nice car/engine anyway :thumbs:

awesome
What's she putting out now Geoff?
Dave
Dave, we don't know at the moment as it's only been mapped at 1.2 bar.
It will be going back to RSP for further tweaking, mapping etc soon, and then it will be running much higher bar. :D :D
When it's all done it will then go on the rolling road, then we will know how much power it's putting out.
Looks stunning mate and well worth the wait :nod:
Looking forward to my shotgun ride :thumbs:
Looking forward to my shotgun ride :thumbs:I remember that scene from Deliverance :wack: :hurl:
About time mate! Looks like the attention to detail alone was worth the wait :thumbs:
I suppose you better take me out at some point too! ;)
Looking veeeery nice Bubble :D

Very nice :thumbs: wish i still had my gtt :mad:
Always said the plenum should be better so the pipe doesnt go over the hot engine:thumbs:
More people should pioneer with there cars rather than cheap bolt ons.:clap:
WOW :eek: Very nice Geoff :cool:
Cosy stuff Geoff.
can't wait to see it at the next show.
Advanced warning of the new instalment tomorrow. :D :D :D
I bet we arrive home a bit quicker than before...:D :D
Mark, book your space in the pasenger seat now as there is quite a queue building. :)
Consider it booked :thumbs:

Every time I see that car I want to get an R34 GTT :nod:
Well things have changed a bit since that engine was built, so..........
I thought that it was about time that I updated this thread. Things have not gone to plan and the RB30 & T04Z have taken much longer than we first thought to install.
CardiffR33 (Ben) had his car collected by RSP for a similar conversion before mine and the plan was to duplicate more or less everything that was done to Bens, for mine.
I specified some extra bits and bobs, so they were never going to be identical though. While Bens was being done, my GTT had a dummy RB30 installed, so as to get ahead with the manufacture of the custom front pipe and screamer pipe return. The new 120mm deep:eek: front mount intercooler was installed and custom pipework made up to fit.
All the pipework was sent off with Bens for polishing to save time, along with some other parts too.
http://media3.dropshots.com/photos/127158/20080517/210642.jpg
The T04Z just fits below the strut brace :eek:
http://media5.dropshots.com/photos/127158/20080517/210515.jpg
Once again, I specified that the external Tial 44mm wastgate screamer pipe was to be plumbed back into the exhaust front pipe. It has a flexi section to allow for heat expansion and vibration etc. This section will not be fitted for normal road use, but it will have to be on there to keep the noise down for trackdays.
http://media3.dropshots.com/photos/127158/20080517/210810.jpg
I bought another NEO cylinder head so that I could keep the old engine intact as a complete unit and here it is fitted to the RB30 bottom end. Oil feed line to the VVT to keep the variable valve timing functioning too. There are also restrictors in the block to stop too much oil flooding the top end of the engine, which is a common RB problem with high revs.
http://media3.dropshots.com/photos/127158/20080517/210918.jpg
I specified an oil drain from the back of the head to return excess oil externally back down to the sump pan. This has been a time consuming exercise, as the original fitting fouled the transmission tunnel the the engine couldn't be fitted. Another fitting was sourced after a couple of days and the engine and box went in. But the clearance was still very tight and it would have entailed the engine and gearbox being taken out as one unit if there was a problem with the clutch :(
So another smaller fitting was sourced and now the gear box can be taken out independantly. Apparantly the transmission tunnel is different on the GTT and there is more room on a GTR.
http://media3.dropshots.com/photos/127158/20080517/211050.jpg
I didn't fancy a rattly binary action tripple plate clutch and after doing some research and on the good advice from Rockabilly (Bernie) I bought a NISMO Super Coppermix twin plate clutch. I could have saved a chunk with a cheaper ORC, but as the GTT is my daily driver, I wanted something that wouldn't be a pain in traffic.

Work in progress.........
http://media5.dropshots.com/photos/127158/20080517/210143.jpg
Custom oil catch tank and just about everything done now :cool:
I got a phone call while I was at Japfest from Richard Bell and heard it running for the first time :D It has done about 100 miles on the dyno already :thumbsup:
There are a couple of problems still to overcome though. There is a small exhaust leak from the exhaust front pipe, which will be sorted out on Monday. Oh and the bonnet still wont shut.........every time I ring up RSP for an update on progress, I ask yeah - but does the bonnet shut :smash::D
If you see an R34 with a scooby bonnet scoop, you know it's me :D
Flippin heck!!
I was talking to Damo @ RSP earlier on this afternoon and I could hear my car on the dyno with Brian and Rich putting some miles on it and reving to just 4,500rpm.
Sounded great :D
Then it went quiet..............
Rich came on the phone and although it hasn't yet got many miles on the engine, they gave it just one blat to 6,500rpm :eek:
With boost controller off and 1.1 bar actuater pressure, no real mapping and wheel spinning..........

546bhp @ the fly :D
520lbs torque :eek:
Richard said it's going to be an animal and both he and Brian are so happy at how it has turned out, with 0.5 bar boost @ 3,500rpm and full 1.1 bar boost by 4,100rpm :cool:
With 1.4 bar it's going to easily make well over 600bhp with the only limiting factor going to be the 750cc injectors and Nismo in tank fuel pump.
What sort of power are you hoping for Geoff?
What sort of power are you hoping for Geoff?
Well it has the torque that I wanted and as long as it is over 600bhp I will be happy :D It might make 650bhp @ 1.5 bar if there is enough fuel :)
:notworthy
When do you pick it up? need a lift :wack:

Amazing work there by RSP, everything looks like it would had nissan done it :thumbs:
What are the diferences between yours and Bens? Or is thawt a trade secret.

Ben doesn't have the screamer pipe plumbed back into the exhaust front pipe, or have the oil drain from the back of the cylinder head. I think that apart from that they are much the same.
Fantastic and I love the fact its your daily driver:thumbs:
Awesomeness :D :D :D
Dave
Well we did the first oil change yesterday at 390 miles, so another 400 to do and then it is going back to RSP to be mapped next Wednesday / Thursday :thumbs:
Went out in this last night :D half throttle and only up to 6k is all Geoff is allowed till its mapped and run in but fook me its bloody quick already :wack: Loads of low down grunt so no noticable lag and you can just feel it coming on strong at 6k when he has to change gear :( Once its fully set up its going to be a beast :D :nod:
It could infact be too fast :nod:

Not jealous at all
:D
I also drove Bubble's Bomber on Thursday before he took Mark out, all I can say is OMG!!
The difference is unbelieveable, when you put your foot down the car just wants to go, it pulls so well and smoothly. I just cannot wait until it is fully run in and mapped. :)
Only downside to this is that now my skyline feels so slow in comparison...
Not for long though. ;)
I got a phone call from Richard @ RSP this afternoon and he said it made 600bhp with the boost controller off :eek:
So he carried on mapping up to 1.5 bar and the calculated flywheel figures are......................
678 bhp @ 7,500 running 1.5 bar
574lbs
:thumbs::thumbs::thumbs:
Running out of fuel pressure at the top end and the boost is tailing off after 6,000rpm, but I think the power is adequate for my needs :D
Well done to Richard and all at Rising Sun Performance :notworthy
It will be an interesting drive home tomorrow :eek:
.
Nice one Geoff, you must be chuffed:thumbs: any graphs?
OMFG!!!!!!! :eek: :D :D :D :D :D
I had a poke around this last week and it's a lovely lovely thing :smitten:
Dave
Nice one Geoff, you must be chuffed:thumbs: any graphs?
Over the moon mate, I just wanted it to make over 600 and it has by a long way :D
I will post up the graphs when I get hold of them :thumbs:
There is more power there, but it means twin fuel pumps, new front to rear fuel lines and 1000cc injectors, but I think what I have is enough for rear wheel drive :D

30-05-2008, 11:12
WTF - thats just silly :wack:
What a result though. Nearly 700 BHP:eek:
You've got to be happy with that.:eek:
Take it easy mate, that thing must spin up in 5th at 150.....:smash:!!!
678bhp :eek:
You must be over the moon with figures like that :)
Well I left work in Colchester at 2.30pm yesterday afternoon and with the Friday afternoon traffic round the M25:annoyed: I didn't get to RSP untill 6.00pm:(
I was completely knackered and suffering from a cold didn't make me feel any better (could be man-flu);)
After a welcome cup of coffee (thanks Damo) and a chat about the car and a couple of things left to sort out, I left and filled up with V-Power again. My credit card is taking a right hammering this month:smash:
After driving for a bit and getting the oil up to temperature, I changed down to fourth and floored it..........OMFG :eek::eek::eek: dry road and rear tyres scrabbling for grip.........this is going to need respect :nod:
Just putting your foot down in fith and the accelleration is relentless, I have never, ever been in anything so quick.
I made the mistake of dropping down to third to punt past one car on the M11...........one huge sideways moment later :eek:
I allways said to Richard Bell that I wanted a car that would scare me. You soon get used to 500bhp and sometimes crave for more, but this is phenominal, well done Richard and all at RSP :notworthy:notworthy:notworthy
Just need to upgrade the driver now :smash:
Awesome results Geoff :notworthy
Ouch that sounds rather scary! More track time methinks :D

I went for a ride in this last week whilst 'running in':D
AGAIN AGAIN AGAIN!!! :nod:
I was out with mates and didn't get back in until silly O'clock time in the early hours of Saturday morning when Geoff collected the car from RSP. Saturday was spent feeling ill, we both have the blooming flu...
Today we dragged ourselves out to attend a local show with our club, Geoff in his car, me in my skyline...
OMFG!!!!! If you thought the car was fast Danielle, then think again. I tried really really hard but that car left me for dead this morning. :eek: On the private test track, Geoff was in front of me trundling along and in a blink of an eye he was up the road, a dot in the distance!
I now know what the kids can get Geoff for Father's day....
a supply of pampers! :)
:D:D:D
I think I need some racelogic traction control rather than pampers :eek:
Still just a :ghey: GTT and not a real Skyline ;)

I managed to get hold of one of the dyno graphs from Richard after he had another tweak before I collected the car. Lost 4bhp, but I don't think I will notice ;)

OMFG!!!!! If you thought the car was fast Danielle, then think again.
No I didn't think it was particularly scarey but I knew it was only being run in and of course that was fast for being run in :nod:
AGAIN AGAIN AGAIN!!!! :wack:
Danielle, I didn't say it was scarey did I? Didn't scare me one little bit, either driving it or being a passenger. :D
Although Bubble may think differently now after his little episode on the way back from RSP.
I just need to pursuade Bubble that I could do with his old engine in my skyline. :D
