So far all I've done is stereo upgrades. I have a tranny cooler, just haven't got around to installing it yet. What should I approach next? I would like to at least get as far as heads and possibly a cam. I want to beef up the tranny as much as possible, to support future mods and also hopefully last forever I like this car and plan on keeping it. I don't have much money til tax time, but i kinda wanna get a game plan for the next few years, I've never done extensive engine mods and I'm not really sure what i should do first. Don't be afraid to get technical, I would appreciate why I should get this cam and lifters as opposed to that one over somebody saying "errr just get an exhaust lolz".
