Yup...
I could list them all, but it'd be way easier to tell you to check out Full Throttle Motorsports

I've got a couple good bolt-ons but its not about bolt-ons......

......its all about that <b>BOOST!</b>

I'd recommend saving up for a turbo kit.

The Boost Boys @ Hahn are going to release a Turbo Kit real soon. So keep your Eyes peeled!

Bolt on parts are a waste of time and energy, buy a base turbo kit, you spend the same in the long run and get 60-70% more power over a whole pile of bolt on parts. And car will run better then a heavily modified NA car (noisy+rough running) <br>

Ya, I think I'm going to get an intercooled kit for mine. Was interested in the kit being developed at cavalierconnection.com, or the Hahn Racecraft Stage 2 kit. Looks about 4 grand USD for either. Refinancing my mortgage for a lower rate soon, so I might grab a bit of cash to juice up the Sunfire a bit. Be interesting at the local Street Legal drags. Get the forged H beam rods also for another $400, or you might have an accident as you crank your power past 285hp. From what I have readl, 375 hp is pretty easy to attain, especially with a port&polished head, maybe even a bit more with a mild cam. I read that the cylinder head sealing problems start around 450hp, which is actually pretty high, all things considered. I think 400hp in a J body is more than adequate for spanking some Mustangs, don't you think? I'll admit, I've had a lot of N/A performance cars that I've modded over the years, including doing my own headwork, but this would be my first turbo car. My basic understanding is that if the engine strengthwise can handle it, keep cranking the boost, and add fuel accordingly, so that it doesn't run lean(detonate). As long as the turbo can support the boost, and the internals can handle it, and you can keep it from running lean, everything should be fine? Any experience turbo modders out there with advice? Am I on the right track?

An extra 400hp to beat mustangs?? Lol, I know guys spanking mustang gt's with 2.4's and a 75 shot + mods. I wouldn't say 385hp is easy to obtain, remember these are economy cars...at those hp levels axles are going to snap, things are going to break...axles/trannies will definitly need beefing up, I don't think the auto will be able take that much torque without some beefing up, the rods (which by the way, you can get for $245 right now on ebay at Rk Sports clearance sale...Eagle forged ecotec rods, I picked up a set at that price maby you should too), the forged low comp. pistons, better bearings, better headgasket or O ringed block and copper gasket, upgraded oil pump,
etc. <br>

Do you know where to get an upgraded ecotec oil pump, better bearings, and better headgasket? Also, I read in SCC that the block has piston squirter bosses in it, I wonder what'd be involved in firing those up? I will look into those rods and pistons.. Just a note, I think it was around 450hp where they ran into sealing problems with the head gasket on the GM Performance ecotec drag engine project. I figure keeping the power under 400hp will keep things relatively safe. I hope the stock axles/drivetrain will hold up(5 speed manual). I've read that these components are generally a lot beefier on these cars than on their import counterparts, which is good news.
