Personally if your going to stick with 350hp i would stay with FWD, i have heard a few people say that 4WD big turbo cars running that power don't feel as quick and are not as much fun. A well set up FWD car is easily capable of putting the power down from 2nd in the dry
If your thinking of 450+hp in the future then go for 4WD.
As for gearbox i am still running 5 speed with ATB diff although gear set has been Cryogenically Treated(frozen) and its never let me down running 370hp with racelogic launch control..
