mod help.

[R33-Gts25t]

Hi juts looking for some advise.Ihave a r33 gts25t I have a 3" exhaust from the turbo bak,high flow filter,blow of valve,boost controller with boost risen to 12 pound.What would be the best thing to mod next.Would internals be a good idea like cams and pistons or bigger turbo and cooler? thanx for any help.

Probably best to lurk your way around the general or forced induction sections and get feel for what your looking for first. There is alot of technical knowledge in there for beginners like yourself and you will learn alot.

The cooler would probably be the next step followed by some kind of engine/fuel management (powerfc, safc, etc, etc) then you go to the manifolds and or new turbo. With all that, if you do it right, you should be able to double your power from stock. Internal work is for serious budgets and serious power (or exploded engines)

Hopefully that gives you somewhere to start but i still suggest having a look in the tech sections. Do a search if you want to research something specific.

Everyone has their own opinion best to make ure own mind up.

Oh and welcome to da forums

like boostzor said....

look at getting a front mount and or some engine management.

if your not looking for huge power but a fast car (about 13.2 for 1/4 and ~270ish rwhp) then go for the safc and the fmic and maybe upgrade to an ebc if you have a bleed valve....

but there is plenty of info already on the forum in the search area

ps. you dont happen to have the same colour car as mine do you?

dude safc first..

then cooler at 12psi

we are coming to winter.. so yeah

first make sure your fuel pump is running ok - if it isnt it can cause major problems e.g pinging.

Do FMIC 1st, you can buy a trust kit from $800 now (on specail at greenline and negun) or else get a hybrid cooler (they sell from around $250 to $400) and then get the piping made up for you (cost is around $600-$700); then go safc 2 or PFC, I would go PFC as it is a complete ecu and then you do have to sell the safc2 down the track and then buy a pfc and buy for my tuning time.

also good to invest in a heavy duty clutch if you dont have one already

[NO_RSPECT]

mikey why do the cooler first

so the car can remain inefficient in the meantime??

so it can run extra rich in the meantime...

[Boostzor]

But cooler is soo shiny

And you have to tune up a new safc or pfc so may as well do it with the cooler in so u dont havet ot do it again down the track. Sure its prolly gonna suck it down but they should be done pretty close together anyway.

[fane]

better off getting safc on its own or safc and fmic together as just adding a fmic without a safc wont make any increase in power at all.... as it will be running rich with some serious flat spotness....

go both...

[Boostzor]

I always thought that if u ran up around 12psi u needed and IC to stop it pinging and going nuts? hmm maybe im confused, dont forget that ive never had an RB powered 'line.

:werd:

Looking at $3K total (including dyno tuning) but so much better than anything else you can do to your car as a stage 1/2 before you step up to replacing turbo's, injectors, surge tanks, regulators, wastegates, etc etc....

[JXL]

safc on the cheaper side but hell do some suspension work get the baby to really handle.

it will spike with more hp but actually wont be any faster coz your power curve will be shit

[ossie_21]

How much would a safc cost????????

Am looking at getting this & a fmic once I have sold my car I have now. Should have my 'line within 3 weeks max.

[Kaido_RR]

safc II cost anywhere from $300 to $600 (depending if u buy 2nd hand etc) tuning cost i think is from $200 to $300

Oh yeah, what are some of your opinions about front mounts???? Some people say that paying more for the recognized brands or Japanese brands (ape int., trust, HKS etc), dosen't really give you any advantage over some of the kinds you can pick up over here.

I just don't want to pay over the odds when I get one, what sort of prices will I be looking at for a fmic?? (buying, piping, fitted etc) Any advice would be tops, .

[3R1K]

like all ppl say FMIC and powerfc, don't do anything else, maybe good tyres?
