There are alot of bolt-on's you can do with 500.00, it depends on what your looking for?? I'd say get yourself some gears...its the most bang for your buck. Then get yourself some drag radials later on...then just start knocking out piece by piece of the rest.
im jumpin from 2.73s to 4.10s if i do it though, and on the highway i hit like 2750rpms in 5th at about 80-90, how bad is it gonna be with 4.10s? i cant be at 4K only doin 80 in 5th
I like my 3.73's.. 4.10's WOULD be more fun in the city, but i drive a 400 mile trip a few times a year to and from college and would hate to be taching over the 3k RPM i'm doing now at around 85mph- i feel bad enuff about that
if you have the 2.73's in your car right now 3.73's will be a jump and feel great.. I'm gonna duck and cover now before the 4.10 nazi's eat me.
good luck, and also consider an intake plenum.. I ordered one from www.dragonperformance.net and it should be here soon.. i think it'll turn out being a good investment
