7at 4.08 FD Thoughts

I swapped the 3.36 for the 3.7 in my G37, it was by far the best mod I did and the only thing I lacked for full bolt was headers. ( To include a PST carbon driveshaft with aluminum U's) . I did drop 5mph on top speed and had to have the speed sensor code turned off in uprev and lost cruise control. I did a simple pumpkin swap from a 6MT to my car and paid under 400 shipped on ebay. Took about two hours to install in the garage using two jacks and stands. ( One jack dedicated to the pumpkin because that bastard is a beast. ) 4.08 gives a bit better accelleration at the expense of traction. Another option is 3.9 but if you can locate a 6MT pumpkin instead I'd just go the way of 3.7 and enjoy.
