Well, a street only car doesn't need an intercooler. Track car is a different animal altogether, although I have seen non-intercooled Promotive installs at the track. If you run a relatively small pressure ratio (ie 5 PSI or so), you don't need a rebuild on the engine (providing it is in good condition to start with). If your engine is not in good condition, then you are starting to look at serious money...rebuild plus which point you may want to consider 3.6 swap instead of a turbo. The stock Motronic pistons will be OK. You can probably find some used plumbing and maybe a decent Garrett turbo on the cheap if you keep your eyes open for it...lots of guys start out with turbo projects and give up after awhile.

It is a lot of work, and a lot of headaches, and there are about fifty things which will not go well and take up a lot of time. The end result will be maybe in the 250RWHP range, so you will essentially end up with peak 3.6 HP without the broad 3.6 torque curve.
