After the engine was rebuilt i bolted on an rb25 turbo. Before the car was a stock rb20det with a 3"inch exhaust system. It sounds like when a car is leaning out. The most the car comes on boost the worst the sound gets. I changed my injectors bcuz they were leaking, i bought some used ones. Speculation has lead me to believe the stock pump could be the problem.

Well i'm gonna check that, my lean rich guage also fluctuates from rich to ideal and so on. Its really annoying cuz i feel as if i'm not building any power.

Ok fellas. I have a r32 gts4 with a rb20det in it. I recently had the engine rebuilt everything brand new. I also did a turbo upgrade. I placed the rb25det turbo my motor. Now the car is making a sound like its blowing wind(bogging down) when i reach about 6000rpms. What could be the problem with it?

Well after pulling out my valves we saw that they weren't seated properly so we grinded the ones that i already had. And now i'm starting one click even when its hot. Exactlly what is the "CAS?" Check the compression on the engine and lets see what its saying. Remember if its less than 100psi your valves are the problem. The compression is leaking pass the valves due to the head warping.

Hey Juvv my car starts normally again. After checking all the electrical stuff like running an ecu check and other stuff it turned up nothing. So i decided to lift the head of the car and guess what? We found leaking valves man. So this is what you do run a compression test on each cylinder. The compression on each should be between 110- 140psi. Let me know whats up. If the compression is below 100psi,get your mechanic and you buy some new valves or grind the ones you have is they didn't melt or aren't burnt badly.

Hey man, I'm having the same problem with my r32 but when i did a ecu check it told me(after i let the engine warm up) that something was wrong with the knock sensor. I'm not really sure what the knock sensor does but i'm gonna have a look see and post my result. Let me know if you come up with anything.

Hey Guys exactly what is an FMIC?

I need a head gasket or a metal head gasket for my car. Does anyone know which company sells them and where they are located and if they have a website. Thanks much.
