Auto tranny is pretty solid...Im pretty sure your good up to somewhere between 300-400whp

however its a good idea to stop boosting around 7PSI or 300whp before you build the engine

Yeah Minesbetter was pushing 13 psi on his auto and it held up fine. I would talk to TC about getting a built tranny if your concerned. You should worryabout getting a shortblock first though if you have big plans.

Also do you need the fuel pump with the 2.75 pulley? I thought you could get away with just injectors
