FIrst of all I would go with more then a stock t5 trans. They aren't built for that much power. A stock 5.0(225hp) will kill a t5 in just over 100k miles. I would recomend upgrading to a t5z(93 cobra) or a tremec transmission for the added reliability.

I would def go with 3.73 gears they really give all the power you want still keeping the driveablity
