so i finally have 300 horsies running around in my engine bay!!! it was a fight getting them all in there and quite expensive but i made it...

now i need the oil cooler on and then time to hit oran park again!

to get these horsies in there i used:

HKS GT-RS turbo kit

Just Jap FMIC

Xforce 3'5" turboback exhaust

Apexi Power FC with Boost Control Kit

Apexi Power intake

Splitfire Coil Packs

forgot a couple of things:

Nismo 555cc injectors

boost is 1bar...

guys who r getting more for the same or similar setup... any tips for tuning or adjustment?

did you have to tighten the wastegate?

if he is running 300rwhp with a gt-rs i would say he is running about 12-14psi. as they normally make 350rwhp @ 16psi (generally not always, depends on the condition of ur engine etc )

I'm on 255rwkw with the GT-RS @1.1 bar.

Is that 300rwhp or 300hp at the engine? i'm guessing if you say its in your engine bay then its at the engine? Because if thats the case it seems alittle low for a GT-RS on a rb25...i was just wondering and not having a go at you...

1 bar is just creeping up into that turbo's efficiency range...whack it up to 1.2-1.3 and she'll come alive...tightening the wastegate should not have an effect on peak power as you max boost should be controlled by the PFC boost controller...however...there should be enough preload on the actuator to hold the wastegate flap firmly shut...

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
