Here are my know little pretend experts answer :_:

1)How much will it cost to make a Silvia S15 Spec R 350WHP?
I will said it range from Rm 20,000 to 30,000
2)What mods needs to be done ?
I assume your S15 are stock standard, you need
a) Good ECu ( Apexi D-jetto / F-COn-V-Pro),
b) High cam ( valve spring if you want lift higher than 10.5mm)
c) Min 555cc injector,
d) Intercooller
e) Oil cooler
f) Fuel pump, fuel regulator
g) Equal length manifold, exhaust, downpipe
h) 1.5 to 1.8mm metal Gasket
3)Will car be still reliable?
I will said, if you good yourself a good tuner yes, but to answer your below question, I think it is possible to reach this target using stock turbine as I saw a lot of Japs magazine had did it. But I always think this way, if you use the max out of your turbo, changes are you will wear down your turbo easily.So it is realible , is really to me unprove issues but I will say if using stock turbine, nope it is not reliable.(p/s I might be wrong , don't shoot me :mouth_closed: )
4)With stock turbine and intercooler,is it possible to reach my target without sacrificing reliability?

Please help!
Thanks!

Err 350whp ? bhp ?
the $$ vs can be very big different

you can spend 100k easily just to get 300hp car

 

[Doink]

yeah...money matters...but the most important thing is that do you really need that much power on tap???

 

[DarkChild]

In addition to all that power, you will need to upgrade your brakes, rims as well as suspension.

 

[cutebum]

easy la

aiyo! easy la buy an equal lenght manifold with GT3040 not GT3037 boost at 1.3 with motec m400/autronic sm4 + MSD4+/CDI 500R.. the rest u figure out yourself k...haha...yeah full boost will hit at 4k with good tuner!

a) You can you L-Jet too, saves some $$ on tuning and installation. Will need a z32 afm though.
b) get something suited to your turbo, not just the biggest and lumpiest cams you can find. Tomei poncams are a sensible choice.
c) 555's aren't going to safely fuel 350rwhp. Some 800's would be nice (If you're trying to save some money, perhaps go with the 2ndary injectors off an FD, but you have to find 4 :confused_smile: )
h) Maybe 1.2mm.. 1.5-1.8 is a bit thick for boost IMO
Still need some other basics like rocker arm stoppers, valve guides/springs, 60mm throttle body from Q/Spec S, thicker radiator like a 3 layer koyo, high press radiator cap (can get a cheap z32 one, factory 1.2bar, or just buy new ;p) , low temp thermo and some new silicon hoses, you will need a new turbo to run that much power safely. HKS GT-RS is a bolt on, ultimate response turbo for SR20, and should be able to max out at 350rwhp. On 350hp, don't expect your stock internals to last as long... and on S15, don't expect your 6 speed to last either.
You'll need a new clutch kit of course, and upgrade your suspension and brakes as someone mentioned earlier.

A "boost up spec" S15 is pretty fast already IMO (modified on stock turbo). Probably more than enough for street driven car. 210+rwkw is quite fast...

oh well, just my 2cents :cyclops:

 

[Stormvolution 9]

Errr... 350WHP = 350 Wheel hp right??? Which means 350/70% for RWD = 500hp on engine wo...

Definately need a GT 3037 turbo kit or bigger kit, big fuel pump, bigger injectors, fuel rail, stroker kit, big i/c kit, big radiator, stand alone ECU, mayb after mkt LSD for this kinda output n oso a Nismo gearbox... Dun think de ori S15 box can stand tht kinda power... Not an expert in S15, but luv it n read lotsa mag abt it... Errr... not sure RM 50k enough to build it not let alone de 20k-30k...

Not really difficult, just boost more than 0.9 bar with the spec below and you are done.

do you mind telling us your 30k dollars modifying cost for 350hp? he..he..

 

[cmng]

you can spend RM5k to build a 350whp anytime
but it just whether you want or not ?
some people spend 5k can get 350whp
but do that last ?

somepeople bought tomei Engine for 60k. but run it at 350whp only

it just how you want to build it ..

You've got umpph under your hood.With a little more boost up,I'm sure 400++hp is not a problem. Congrats!
