This site is for Cavaliers, but they do have an expanding variety of 2.2 and 2.3/2.4L performance parts. Some kinds which haven't been available since mantapart closed down. I know they are the only place I could find selling ARP headstuds, camshafts (new cores), selling beehive spring kits, stroker kits, pistons, adjustable cam gear (2.2L) and a few other things.

I have no idea what their quality is like, but it's worth posting up for someone looking for some of the only performance parts being made for our older engines.

Its interesting. I'm a little disappointed that the 2.3 doesn't have many parts listed, but they concentrate more on the later twin cams and ecotecs.
