New Gears
Ok, so Ive got my body all fixed up and I'm ready for some small drivetrain stuff, my neighbor said I should go with some gears, he said the 3.73 is a good set, but I've read and alot of people say to use a 3.42, I drive about 40% highway, if even. So basically what I'm wondering is what kinds of performance would I get from a 3.73 as opposed to the 3.42, I have a 94' 3.4L v6. Thanks.

I guess im one of the best to ask about gears on a 5spd here lol. I've had the stock 3.23's, 3.42's, 3.73's(what im currently using) and 4.10's. I dont do highway very often so its not a huge deal for me. But personally I saw a very small difference between 3.42's and 3.73's. About 400rpm difference at 70 mph. With 3.73's I do about 2800-3000rpm@70mph.
The only reason i'd say to jump to 3.73's, is you wouldnt notice much difference between 3.23's and 3.42's(im not sure if you have M5 or A4 though, so you could have 3.03's).

Ok, and my other question is, how hard is the install, and the tune. My neighbor is like a master mechanic with basically every kind of tool in his garage except a lift. but is it something that i would need to take to a shop?

no, you dont need a lift to do them. the speedo actually has to be recalibrated though. I believe youll have to send in your PCM to a company, or find someone with the software. My speedo has been off for over year now.. I really should have sent the PCM in this winter.. but I have 3.42s and mine is close to 5mph off.
