Re: i want some boost

if you get a kit that should come with most everything you need for the project
what year and what engine do you have?
if you have a 4 cylinder i would get the turbo. 10 psi out of a turbo will give you more power then 10 psi out of a supercharger since the turbo doesnt rob so much damn power from the engine to operate

Re: i want some boost

If you've got the 2.0 or 2.2 OHV, don't boost it, swap engines or buy a new car.
If you've got a V6 or a DOHC I4, it depends on how much power you want to get out of it (whether or not you're going to upgrade the botom end), how long you can go without the car, and what your mechanical/fabrication abilities are. When I put my supercharger on, I needed something that I could easily do in one day because I didn't want to drive my truck every day and get 6 MPG for 30 miles x at least 5 days . The supercharger also made sense because it was a GM kit (discontinued, don't ask ) that I had to bolt on and then I was done after a PCM recalibration. I also don't need insane power (gonna buy a V8 RWD car when I start throwing my money away, looking at the 2010 Cameros... Just hope GM is around in a few years when I can afford a new one), I just wanted enough to make the 4 cyl a little bit peppier (and I waaay overshot that goal ). It'll be about the maximum HP that the bottom end can handle after I'm done with the intercooler and FPR, and I'm not going to put rods or pistons in an economy car, so the supercharger worked out perfect for me. If you plan on racing it and upgrading the engine eventually, I'd say turbocharger. If you want to make a 4 cyl move when you want it to and not do much else to it, supercharger.

Or if you plan on swapping engines eventually, I would go with NOS short-term because they're pretty much universal so you can swap it to your new engine or sell it to a wider range of buyers. Long term NOS would be more expensive, but a decent "fix" until you get boost.

I suppose, after looking back on all that typing, I should have just asked "what's your goal for this car?"

EDIT: OK, I clicked "back", and saw your name in the last two posts and then I put two and two together, and relized almost everything I typed was a waste of time
http://www.j-body.org/forums/read.ph...6&t=419186&p=1 A guy on there was making 287 whp at 13 PSI on a stock 2.2. So I guess I was wrong about what it can handle, but I think he's got TONS of money in it, and just because it can handle it doesn't mean it should. I'd still say go with a 75 or 100 shot of nitrous oxide, with 215 HP you'll blow those Civics out of the water. One of those guys apparently thought he could beat my Cavalier (looking at it you'd think it was bone stock), I could see him in the rear view mirror before I was out of 2nd gear with (again, estimated based on what others have had) about 220 HP. You'll be happy with that HP, you probably just won't like refilling the bottles.
