180° Thermostat and an extra tranny cooler FIRST to solve the heat problem before you make it worse with mods. After that, intake and exhaust. The only Bonneville specific intakes are available at angryducktofuracing.com or www.angryducktofuracing.com
or pm 99bonnevilleSE here on the forum. He'* also building a set of headers if you want to replace your factory headers (the 94 came with them), and he'* working on a full exhaust.
has a fiberglass hood with scoops and heat extractors. It'* the only one available that I know of. He can also get you anything else you see on his site, including slotted rotors for cheaper than Powerslots. You can also email him at firstname.lastname@example.org
After the basics, you can move on to a Chip (read my signature for my suggestion on that), smaller supercharger pulley, and on and on. Don't do ANY of the performance mods until you change the thermostat and add the extra tranny cooler.
Good luck (and PLEASE don't put a ricer wing on your car)
