you defiantly need to get a boost gauge in there and find out what its running. without knowing exactly what is inside the engine, and what boost you are running, you are running a very big risk of wrecking things.

i recommend driving it nice until you know a little more about the car.

as long as the car seems to be running fine just take it easy, find somone selling a set of stock coils and springs cheap, and hookup with someone for an inspection, maybe map or db depending on where you live.
