I have the stillen stage 4, and the car is quick. Car has great power from redline. I have a 95 300zxtt with almost 400rwhp and the stillen feels much faster since the roots supercharger gives almost instanst boost. I know turbos have more potential but for your application if you just want to bolt it on and make good power stillen is the way to go. I had my car dyno tested and the AFR was perfect with the stillen split second box. I also hear people talk about belts, I have about 4,000 miles and about 6 track events two 3 at homestead and 3 at sebring, reaching speeds well over 140mph and there is not one single frey in the belt whatsoever. I rag on this car and the motor as hard as possible and havent had an issue. This is all in the south florida heat only thing I am going to add is an oil cooler.

 

thinking of adding a oil cooler is a good idea. I may want to get one for my turbo set up just running low on cash right now.
