Anyone have 0-60mph times for Spec R Jap Model?

[londoner2001]

Am considering an S15 Spec-R Jap model automatic 200sx(what a mouthful!) and am wandering if anyone knows what the 0-60mph is for the tiptronic/automatic model, I know it has 240/250BHP which is a fair amount and I have heard about 5.4 seconds for the manual but would like to know figures for the tiptronic model.

Many thanks.

[stevec]

Helllo:wave:

Didn't know they did a tiptronic Spec R so you learn something new each day.

The spec R that I have is manual, and 250ps out of the box.

exhaust and filter sees about 300bhp and should see about 5 secs to 60mph.

ps.If you want a manual one give me a shout.

yes, give him a shout if you want a manual one for your own use :D

[londoner2001]

Indeed they do do a tiptronic Spec-R but it is ten BHP less.

I don't think you would get a 50BHP gain from just bat back and and induction kit, realistically 20 BHP at most from what I have seen in tuning Jap cars. I think to get 50 you would need new downpipe, ECU, induction kit and you might then see 50BHP but unlikely still.

Unfortunately I need a tiptoe box so I'll keep looking.

Many thanks.

With a free flowing exhaust & dump/front pipe and some sort of pod filter you will easily see 40KW (50HP) at the wheels due to the boost being raised to roughly 12psi.

On my S15 with just a cat back, power FC, FMIC, EBC, pod filter & 17psi my car has made 192kw at the wheels (257HP)

The S15's respond extremely well to basic induction & exhaust mods.

[ATrull]

they are already nicely tuned sr20s :)

Shot down in flames mate.:D

I have a downpipe too I didn't say anything about a cat back you need to ditch the lot.
:D

Speak to Kiki at Option Motorsport, he said he could map my car to 340 ish bhp with the mods I have. Std intercooler etc..

Like dcoghlan says they really do respond well to mild mods.

get one sorted you will not be dissapointed, but then you might if you leave the road backwards in the thing, which you will if you make assumptions about handling like you did about the power
:wack: they bite hard.

As far as I know - the non-tiptronic Spec R (i.e. manual) does 0-100km/h (0-62mph) between 5.5-5.6s depending on where you get the information. That is for a standard car (unmodified).
Obviously that is with perfect gear changes....

[londoner2001]

At the end of the day you can claim what you like but until you have dynod your car and have proof of the pwoer then a claim is just that, a claim. I don't believe that with full exhaust and induction kit you would get 50BHP you can't talk of mapping because to start mapping the car you would need an aftermarket ECU which is a whole new ballgame and with ECU zorst and induction kit I think you would see more than 50BHP, but you need the arftermarket ECU.

If you want proof, let me know and I can scan dyno graphs of at least 5 S15's which are all making over 145rwkw (100rwkw is standard) with just a full exhaust and pod filter, some are even making up to 170rwkw with NO ecu mods and NO boost controllers, Just exhaust and filters.

you don't need an aftermarket ECU if you have access to the consult mapping software.

which Option Motorsport have.

Why are you so agressive about something you obviously know litttle about:confused:

[Duck Dodgers]

Option Motorsport - not come across them before. Steve - you had a lot of dealings with them?

Pete

[Greg]

Option Motorsport - based in Silverstone.
I have not yet used them for my S15, but they seem competant and know what they are on about. A good source for HKS parts.

Non at Option has a a red drift spec S15 which is now running close to 500bhp, so knows a fair amount about S15's. :)

[Duck Dodgers]

Do they have a website address?

Is his S15 anywhere to be seen? - that's a helluva lot of fart thrust

[stevec]

website..

http://www.optionmotorsport.com

not had any dealings personally as they are a way from me but I know some very satisfied customers !!

[Duck Dodgers]

Thanks matey. A bit out of the way for me aswell but worth a butchers

[rm_dragon76]

hey all,
just read previous threads.

Previously dealt with www.optionmotorsport.com for my previosly owned rx-7, option customer service exellent and they are masters in tuning + reliability. :thumbs:

I think you need to read the replys. With a figure like 257 HP@ the wheels it aint going to be a guesstimate. Oh and he said he had a power FC which is an aftermarket ECU :wave: You have assumed too much about something you obviously know little about (the s15)
Would be an idea to stop that now and have a listen to the people here that have s15's and know what they can do. Remember 50 BHP from a 250 BHP engine is only 20% increase.

Well said Martin :nod:

[DAVE610]

What boost do S15 run as standard?

[stevec]

0.7 bar but it is on a strange controller which feeds in .5 bar until about 5500 rpm then full boost comes along.

changing the zorst and filter will let you see just about 1 bar with all the std boost regulation in place.

hth
Steve

[DAVE610]

I think the other way to Londoner2001, I would have expected a lot more than 50bhp extra at the wheels with the kit and the boost you are running.

[londoner2001]

Sorry been away from this one for a very long time, just noticed though on Option Motorsports site that to give you an extra 25-45bhp they advise exhaust, intake kit and ECU upgrade, what happened to these claims of 50bhp from just exhaust and intake kit? Thought I was an idiot, seems Option think on same wavelenght as me!

[stevec]

ffs this has been flogged to death. :rolleyes:

Speak to kiki and tell him you plan to get a front pipe, de cat, rear exhaust and an induction kit, and ask him what power you should see.

he told me 300 bhp, and having driven a fair few cars of this or more and it feels like about 300 bhp. which is a 50bhp gain.

Kiki also went on and said he could remap my car as it sat, in the state of tune above and get a reliable 340 ish bhp, without even changing the intercooler :nod: this should be about right given the injector size.


so instead of whining about it, get one tuned up and prove me wrong...

Are these figs. definately correct Steve? :confused:

I mean, 1 bar is just under 15 psi (right?)

then 0.7 is about 11 psi,

can an SR20det make 250hp with only 11psi boost on a T28? (OK a BB turbo, but what else differs from the S14?)

(or have I been getting my sums wrong here?)

[stevec]

That is pretty much right mate.

It still has the variable boost and I dont see one bar until 6000 rpm.

as for differences, there are a few.

Air flow meter, injectors, intercooler, turbo, fuel map.

plus I expect the exhaust is different too.
the air filter has a direct feed into it from a vent under the middle of the bonnet, dunno if S14's have this..

then you have all the std goodies like vvt that the S14a has.

hope this helps.

I am saying that yes. I spoke to Kiki at a drift practice day. And he said he could map my car to 340bhp. WITHOUT fitting a fmic.

295bhp is 300ish isnt it :rolleyes:

I am going to sell my car soon so I wont ever get it on the rollers but I really don't care TBH my S13 will destroy it anyway.

/Steve

[londoner2001]

the 295bhp is with the ECU upgrade and is maz of what they estimate, you said 300 without ECU upgrade, I still think it is absolute bollocks to say that with exhaust and induction kit you would get 50BHP gain and their website supports my view.

[Julio]

Just scouting around and have read this with some interest.50 bhp extra is easily doable with just an exhaust and filter. The car i own (Mazda 323gtr) has a 1.8 engine with rb turbo as standard. They make 210 bhp as standard but they respond ridiculously well to tuning. For instance a car with filter and 3 inch bore exhaust made 281 bhp (yes that is correct a 71 bhp gain). This car now runs 340 bhp with same exhaust/filter, but now with fmic, catch can, boost controller and a couple of other little touches and is running high 12 quarters. He hasnt got the new graph up yet but have a look at http://www.323gtr.net/ and go to records, then look for Lee in the bhp section at the bottom and his old 281 bhp graph is linked from his name.

Why these cars arent more popular i dont know (might have something to do with the chocolate gearbox and the fact only 2500 were eva made :( )

Anyway hope this cleared a couple of things up.

you'd better get back to tuning your na piece of sh1t engines then, because if you are only expecting gains of 1%-5% you will be extremely dissapointed.

I don't understand your problem. maybe it is just me, but a tuner will always err on the side of caution, and option are about as modest as they get. their business is run through word of mouth. you will never hear Kiki boasting about how much it can be done to, but he will tell you if you ask him nicely.

it is a commonly accepted fact that with a boost hike to 1 bar on these engines (with supporting mods) you are looking down the barrel of 300 bhp, you may not have more but it wont be alot less.

The S15 is a quick car, I have yet to find anything that pushes me down the road while I have been out.

It keeps up with a scooby which is quite well tunes up judging by the tuning company stickers all over it, and that was in the wet and on B roads. and yes the bloke was trying.

If you want a quick car then get one, if you want to talk power figures all day long get a GTR. The SX is a drivers car and why youd want an auto is beyond me :D :ghey:

I'll post no more on this unless you have any digs at me :whip:

Oh of course. A 50 BHP increase isn't possible from a complete decat, full free flowing exhaust system and a decent air filter. Why? Because you say it ins't :rolleyes:
Why is it then that an S14a with 50 BHP less sees nearly 50 BHP for a filter and exhaust?

You do know that boost increases when you fit a filter and exhaust on a turbo car dont you :rolleyes:
Have you thought that the ECU upgrade could be pretty much bugger all? Maybe just removal of the fuel cut defencer? Do you know what one of those is? :rolleyes:
Did you know that the S14a intercooler will happily support up to 280 BHP?
The s15 one of 50% larger!
Notice that for 340 they say ECU remap (not upgrade) :rolleyes:
The point still remains - 300 is only a 20% increase. Do you think that say a low restriction zorst would only do 20 BHP on say the 8 litre W16 with 1000 BHP in a 16/4 veyron?

As for your 20 BHP claim I have an s13 that has only 165 BHP standard and with a filter and exhaust made 190 BHP so thats more than your 20 BHP increase - and that was with standard boost as the actuator was adjusted to make it only run 9 PSI! - Thats over a 15% increase and relatively speaking the s13 intake and zorst is less restrictive to the less powerfull engine.
I have graphs to prove that aswell and they have been posted before on this board.
Bare in mind that the s15's and s14a's exhausts are relatively speaking far more restrictive than the s13 ones and that'll explain the sizable boost increase they see.

[docwra]

I don't understand your problem.

Hes a prat and a troll. Coming onto undoubtedly the leading forum for UK S15 owners, and quite possibly the best 200SX forum worldwide, and the proceeding to tell the people who actually own and tune these cars they are incorrect ............... :rolleyes:

Never mind using Kikis website and figures against people who actually know the bloke and take their cars to him to be tuned .......... :rolleyes:

[SM]

Found this thread amusing .. as stated SXOC knows the SX like no other tuning company, individual or team, that is that much knowledge here its just :notworthy

We all know how easily tunable the SX is :thumbs:

Talking of Option .....
I've been recently speaking to somebody with a S14a that option look after, they have charged for, and claimed to have loaded a new map onto his S14a ECU. I'm lead to believe it is possible for the S14, but not S14a. Does anyone know if it can be done on the S15 ECU ? No piggy back chip was used.

[stevec]

i believe option tweak the ecu map itself rather than changing anything :notworthy

as far as I am concerned when it comes to tuning these cars option are the nuts, and I have never actually used them.

They just know their stuff so well.

If I were local to them I'd be a groupee :nod:

/Steve

[Channie]

Steve why you sellin your S15? Wouldnt mind a race wit ya? :)

Option said to me they use Motec piggybacks, not sure which model, theres about 3!

That londoner bloke shouldnt argue wit people about a car which he aint got.

Besides which if he gets an auto tranny its gunna have less brake and its gunna be a fair bit slower than the manual ne way.

you'll have to settle for racing the S13 :nod:

Yeah they use the piggybacks for higher tuning but for the level s mentioned in this thread they just re tune the original chip... well going by price anyway... £200 odd quid doesn't buy much ecu modification ! :eek:

I have moved offices and I now commute around 80-100 miles a day(depending on which route I take) and the S15 is just too nice to do that sort of mileage in plus I need a dieseasal car that does about 50 to the gallon :whip:

so what do you want to race me with then ? :) I had an EVO6 last week, embarrassed an Golf GTI R32 (how dare they use that name!!) yesterday. dunno how quick they are supposed to be but the evo was a good kill.

cheers
Steve

[Channie]

Ive got a spec-r, 6sp, Greddy BOV, Airinx and Trust EVOII (on the way, hopefully).

Seein as you neva see them about, thought it would be sweet to see two racing! I'll settle for a race against your S13(make you wish you'd neva sold the S15!!!)

Wot mods did you have on your S15?? Ne recomendations?

[stevec]

just basic stage 1 mods, apexi air filter, trust front pipe, de cat and trust power extreme II rear exhaust.

apparantly provides around 300bhp.

The S13 is quicker and corners faster...now. :nod:

300ish bhp per tonne in the S13 :thumbs:

should have over 300bhp and it weighs 1100 kg, fully stripped out, roll cage, coilovers, stage 3 horsham developments conversion, full kit, fibreglass wide front wings etc..

bring it on fella ;)

/Steve

[Channie]

Your S13 sounds the mutts nuts :thumbs: !

Im tryin to keep all my mech mods Greddy/Trust and electrics Apexi. Just put on an Airinx dome and Greddy Type S BOV, and waiting for a Trust Evo II zorst from SVS. After that some coilovers (which im still undecied about :confused: ) and possibly an Aexi powerfc very soon after. Then all my funds will be depleted :( !

Any advise about suspension??

[stevec]

It will be if I ever get it finished !

With regards to suspension, check out Whiteline's website. I think it is www.whiteline.com.au they have a lot of stuff available fo the S15.

They also say that if you cant afford to do it all then leave it std. in std form it is probably the best handling car they had tested (according to them)

if you just lower it without setting it up for camber etc, then you will ruin the handling of it (apparantly)

This is why I left mine the std height.

the whiteline suspension kit isn't hugely expensive though, if you compare it to some of the more exclusive Japanese makes.

hth
Steve

[Channie]

Still cant decide!!!!!!! I think i'll leave it for now, money is being depleated on things like fixing my exhaust and turbo gasket. Finally getting rid of the factory jap stereo which picks Kiss100 up on 82fm :confused: Exhaust is going to arrive (finally!!! :D ) in a week and a half. Not in time for JAE though :( .

You going to JAE Steve??

[stevec]

No I can't make it unfortunately :(

/Steve

[Nicely]

Wow. How did I miss this thread? :eek:

Clarification on a few things I spotted along the way.

You won't get as big a power increase as the S14/a by adding a frontpipe, full exhaust and filter. The reason for this is that the S15 comes with a bigger better flowed standard exhaust than the S14/a.

The S15 AFM is exactly the same as the S14/a.

The S15 (MT) injectors are 30% bigger than the S14/a. The AT injectors are the same.

The BB turbo was fitted on the S15 until 10/2000. It was also fitted on the late S14as. The non-BB turbo was fitted on the 10/2000 onward S15s.

The S15 standard air box is exactly the same as the S14/a.

The S15 WMIC is 33% bigger than the S14/a unit, not 50%.

It is possible to directly remap the S15 ECU (like the S14) due to the ECU not having NATS integrated into them.

The standard boost level on the S15 is higher than the S14/a (by some 3-4psi).

Tiptronic? WTF?! First I've heard. Was a 4 speed auto. There is no option for it listed here (http://www.bengoodger.com/cars/silvia/jsite/options/options.shtml) either.

I don't dispute the tunability of the S15, however, 340 sounds FAR too much on the standard WMIC, AFM, plugs, injectors and fuel pump. The AFM itself would start maxing at around 310. The standard turbo would maxed out too. 300-320 fine.

[Topper]

What kinna power you running now Nicely, you must be over the 300 mark now?? Especially at 1.1 bar.

[Nicely]

I'm not running 1.1 cos my turbo gasket is blowing. :rolleyes: Also I've still got my unpredictable boost. If I try to run 1.1 it flies up to 1.2 when I go past about 5-5500.

I'm not going to say what I'm running until its definite on an RR. :)

[Django67]

Nicely, I just love that pic in your sig of you launching the S15 with the front wheels in the air. Awesome!
