for a turbo build and with this build what turbo would be best. I have never dealt with boost at all and have been thinking about turboing my GTO but I really would like some opinions from the guys that have already done it.

If you swapped the heads out for a 72cc head you could get your CR to around 10.5 and that would be do able on pump and Meth or E85
