The auto tran's is going to be a little more difficult to play with, but you can still squeeze some power out of it. I would look into either swapping the tran's if you want hellllllllllla power, or look at some auto builds to see how they did on their tran's. I know 8urcivic is really interested in an auto-build, so yo may want to talk to him a bit about his thoughts on the power that the tran's can withstand
