You will have to spend some cash... :( But supercharging it would be the best bang for the buck, and most power minus a turbo kit possibly.

but if i put turbo i would shorten the life of the engine alote right? this car only has 38,000 miles in it used :) idk i am planing to make this car a show car and get a r6 sportsbike to get my thrill

Too complicated.


Drive it off a cliff, it will accelerate at 1 G!

Supercharge it

take out the rear seats and speakers to save more weight

I doubt most people would notice the difference removing the rear seat....although the car will be a bit more noisey inside. The rear speakers you allude to are pretty light. We're talking 60 Lbs total...which will make a 0.05 second difference in the 1/4 mile.

I still like my cliff idea for fast and easy results. :P

In all seriousness there's some great threads in the Motorsport and Track forum. Search "Car and wheel weights"

supercharge... anything else will be for fun (exhaust note, intake sound, chip, pullies, etc)... they make "some difference" but its negligable

try

swapping your differential. If you have a manual your 3.15 diff out to a automatic 3.46 you will see instant powah.

but if you have an auto, I 2nd PEI'd suggestion to achieve 1g

[AMv8(1day)]

If you don't want to spend the cash (4k-10k) on forced induction, go with a diff from Turner motorsports. You'll lose alittle fuel economy and your engine will be reving alittle higher on the highway, but until you get FI, there's nothing better.

word. swapping out the diff wont give you power but youll instantly feel like you did. your acceleration times will be significantly different.

If the turbo or FI system is tuned properly, you will not be shortening the life of your engine. Extended times at higher RPMs do more damage to your engine than occasional increased in pressure. Again, this is all assuming a properly tuned FI system. Yeah, changing your diff will give you more torque, but will also increase the cruising RPM thus shortening your engine life quicker (compared with NA) if you drive a lot of highway. For me, I would go FI.
