Whichever Thunder Racing sells should be fine. They've never done me wrong.

i baught motive proformance 3.73 gears for my a4 i have a magnaflow exhaust a 3200 stall and a slp intake and altonator and underdrive pulley will it make a big diffrence?

the 3.73 will make it go faster, the catback exhaust will give around 12-15rwhp gain, the 3200 torque stall converter will shave off upto .4 sec in 1/4mi and give you lots of toruque to peel out, the pulley will give 10-12rwhp and 2-3mi/gal improvement...

I asked this mechanic guy, and he told me that if I could physically race myself (meaning the same car with mods as me) I would be 5-8 cars in front...
so hell yeah! that's like getting 40-50rwhp gain, but there's no hp gain in gears swap, you get lower gears so you accelerate faster.
I am doing 3.23 stock for A4 swap to 3.73 on 30th I am scheduled.
$220 for the part, $400 for labor (takes about 4-5 hours labor)... I'll keep ya posted how it feels, it will shave off at least .2-.3 off the 1/4 mile for sure.

on a side note: best mods for the money, gears, stall converter and NOS is top 3 pretty much... after that you get into more money for average gains, unless turbo, s/c or heads&cam package which are good bolts on.
