T-Charged-Civic

Hello, I own a 1994 Civic Hatchback, I have this problem, my car runs good, not enought thought, it used to run better with a lame manifold, T3 by garret, and smaller injectors and a smaller intercooler, can it be the downpipe ? because my downpipe is 2" that getting 2.5" after like half a meter, something like that, because of the AC, please help me out, ASAP, thanks in advance, Avi.

How much boost are you running? Is the car tuned at all? 720cc injectors are BIG, especially on a car with a 2" downpipe. If I had to guess I would say it's too much fuel unless your making like 450+ hp. It could be a number of things though. I know on my car it turned out to be fuel pressure. Just start messing with it, and only change 1 thing at a time. If it doesn't help, put it back like you had it. It will be easier to pinpoint the problem that way and you can address it accordingly. Good luck, turbo problems SUCK!

a wide band air/fuel ratio, I had a 440 RC Injectors,

ok, I had an EX, now I own a hatchback,
I had a T3, now I have a T3 T4
I had a lame manifold, now i got better,
I got a bigger intercooler, new plugs,
bigger injectors, everything is better, but the
downpipe, which is smaller, it runs like,
10-15 HP stronger than then.
