I got a catalog from PAECO today, I think I remember Anarchyx34 talking about them before. Anyway they make quite a bit of nice stuff for the N/A 2.2, I'm sure some of it fits on the turbo. The best things that I saw were the camshafts. There are 4 grinds, mild to wild. The mild one will rev to 7200 rpms, the wild one goes all the way to 8800 rpms but it requires LOTS of mods
They also have underdrive pulleys, headers, weber carb kits, clutches, turnkey motors. In fact, they have a 2.2 N/A with 229hp for $7500
