First Performance Upgrade Question

[nemesis101]

I have a R33 GTST 1.5, the engine has done around 160,000km's

There is literally no mod, all stock standard except a 3inch exhaust ......

what would be the next upgrade i need to do to gain extra KW??

what manual boost controller would you recommend??

How much psi can the RB25det handle with the stock??

How much psi can i handle with the stock intercooler?

Turbo back exhaust if you only have a cat back, then panel/pod filter. Cut and ground the boost solenoid. But before anything else... Search! This has been covered many many many many many many times

if i could start all over again, id start with engine management, depending on your plans for the car are, then fmic , a good front pipe (turbo to cat) panel fiter with some air box mods to get more outside air in. oh and change yur fuel pump if its still stock ... or do a search

R34 side mount intercooler $150ish

r32 wastegate actuator (holds a safe 10-12psi) $40

K&N panel filter $100ish

Apexi safc fuel computer $250 second hand + tune $150

Maybe an MBC if the r32 actuator doesn't hold the desired boost $35

Should see 200kW with this combination.

id be making sure that your timing belt, tensioner and water pump had got replaced at its 100,000k service...otherwise that would be the very first thing i would do before potentially giving that vehicle more power considering its kms.

Good point!

with mine i did mods in different stages. first i had a full 3.5" exhaust (3" is fine), larger front mounted intercooler, k&n filter and a bleed vavle boost controller set at 10psi = 175kw rw

later i got a power fc computer, bosch 040 fuel pump and tune = 204kw rw

now i got a hiflow t3/t4 turbo, z32 afm, and a nismo fuel pressure reg =241kw rw

later i plan on splitfire coilpacks and 480cc injectors for 250+kw

Hi Guys

I just recently purchase a r34 side mount intercooler and what i have realised is, its very responsive now........i notice it in a hot day....

Now apparently from my mechanic i only have a cat back 3inch exhaust....i dont have a turbo back dump pipe unfortunately

so my question is, whats best for my next purchase?

turbo dump pipe?

Manual boost controller + boost gauge to 11psi??

or

hunt around for an R32 wastegate & actuator

im tempted to go with the MBC + boost gauge to 11psi.... as that will give me more KW....

whats your thoughts??

Playing the bad man forum patron ...

If I went to a bird watching forum, I would assume the question "best cheapest binoculars to start off with" or "best, cheapest paint roller that gives uber even coverage, for a newbie" on a niche interior painting forum, would have been asked before.

Hitting that search button with a ruthless "enjoy sitting in wee drenched jeans" manic depressive anxt, will provide a wealth of experiences.

If you springboard off other ppls experiences (Like Sambo33) plus have a little desire to tinker, you can SKIP technical, and fiscal issues others have had when modifying; hence the use of a forum. Don't get caught up using fish tank pumps for blow by excavation or Korean HID's when you coulda had those sway bar's or high flowed turbo.

Don't mean to be condescending, im just an a55hole who trys to tell it how it is should be
