Wow. There are good jap cars to mod and they're are ones that aren't so good to mod, I for one am not impressed with the 350z's and the G35's/37's. I know a kid with a G35 and yes it has an sts twin turbo kit, among other mods. My buddy lined up with him in his ctsV (stock m6) I was passenger. We went from a stop 3 times. 1st time ctsV got him from 1st to 3rd gear, the g35 slowly creped up, then the kid in the g35 missed a gear we won by default, the g35 was dead even with us, and i need i remind you the ctsV is completely stock, stock air box and everything. We went a 2nd time same thing as the first run. The 3rd time the g35 didn't miss any gear and he beat us by 1 car length. The kid gave all types of excuses why his car was slow blah blah blah, all the spectators were all disappointed, as was I.
