Rb25det Problems Please Help

[ReganGTS25T]

i have a 40th anniversary sII gts25t and i have some problems the car first of all has a small air leak from the fuel rail thats a little bent out of shape and its not sealing, but it still boosts up to 7 psi but the car is really slow, a n/a stock sr20 is faster, the car kind of slugs its way up the tach then at high rpms you start to feel a little push but thats about it the compresion is fine the idle is fine it sounds liek all the cyl's are firing its just uber slow, any suggestions? heh i know its not too discriptive but some help would be highly apreciated

the fuel rail isnt stoping fuel flow, the previous owner i suspect tried toforce the fuel rail out or something and bent it upwards 1 of the injectors isnt totally flush with the manifold so its sucking/blowing air through thier only 1 injector though

That cant be good....

I would take 1400r advice or go see mechanic. before you melt a piston. and check that injector?

easy way to suss it would be to hold the motor at a constant RPM, while spraying some AEROSTART around the injectors while listening.

ok fixed the leak fuel rail leak and its still uber slow, could it be that the vtc is messed up?

check your Airflow meter for gunk, and clean with throttle body cleaner, may aswell hit the throttle body with some as well..

may have an exhaust leak in the manifold so listen for that and check.

check your O2 sensor and fuel pressure.

could be heaps of things man, so check them and see how you go.
