Is there any companies out there that have body and performance upgrades for the 2.2 liter I4? other than RKsport

Dude your wasting your time with that motor. In all honesty, unless you put it in a golf cart.

I am also interested in the same thing. With my 91 cavalier. Check out my web site with some pics at www.rcjon.com/carconnection I want to get a body kit like the one on that page, a flowmaster muffler and maybe a K&N air filter. I would like to swap my 2.2 engine with a 2.0liter 90' engine that comes with a turbo and TBI and 160hp. If anyone has any info on this engine please inform me thanks. The 2.2 liter is only 95hp which stinks lol. But it still gets me speeds of up to 110mph.
