firstly i am new here i am jan from germany , 29 years old and i have to skyline,s in my garage A R33 GTST spec 2 and a R34 GTT. i am a truck mechanic .
my englisch is not perfect but i am doing my best ,
so i have a problem with my r33 GTST spec 2 i imported from japan !
i hope some people here can help me as the forum in australia is definatly the best in the world !
so to my problem,
the car runs fine under 5000 RPM i can boost it and it runs exactly fine trough 5000 RPM , when it exaclty hit 5000 RPMS it stops like it don,t inject anymore fuel !
if i run it wit under pressure so under 0 bar boost then i can run it perfectly over 5000 rpm until it hit the limiter,
so the problem is only when the boost is there ! so if i boost it a little over 0 bar overboost then the problem is there if i run it uner 0 bar then i can rev it perfectly until the red zone !
if i pull full boost it runs fine until 5000 rpm and then it don,t accelarate any more , it don,t react ont the throttle when i putt my foot from the gas pedal and it is under 5000 rpm i can accelerate again,
so after 5000 rpm with boost it doe nothing no schock , no acceleration , i now when it shock then it musst the coilpacks but he don,t schock or vibrate the engine do nothing above 5000 RPM , so it must stop the fuel injection or the ignition,
hope somebody can help me here,
i already cleaned the afm , and check the fault codes and there was no fault codes !
hope somebody can help me
