Re-read your post a few times bud. Can you even understand what you're trying to say? Oh, and add some punctuation while you're at it. Then *maybe* someone will be able to help you.

Ok.

So Basically your friend's Sr is in the car, and running. When he tries to accelerate the engine revs up but its moving at a slow rate of speed. Right?

check for boost leaks. many times you feel a loss of power like that, it's air escaping from the intercooler plumbing because a couple clamps aren't on tight enough.

There are two other causes of this. Clutch slippage, which you would feel as a shudder in the clutch pedal, or bad turbo. Bad turbo would leave oil in the IC piping, and the compressor wheel and turbine wheel will have a lot of play in them if that's the case.

EDIT: S13Guy, if you can't contribute anything useful to the thread, please don't post.

I also cleaned the thread up so it gets to the point faster.

Unplugging either will give you that wonderful WRX misfire sound. Make sure your injectors are plugged in as well.

Unplugging the o2 sensor, or using an incompatible o2 sensor, or a bad o2 sensor will make your super duper slow. Also check your timing, and make sure where it's set makes it run the best.
