He is using e85 but you can do on pump, turbos are easy on the rotating assembly but if you want to up the boost put atleast forged pistons and h beam rods in. Converter is up there from ptc but do dont want to go cheap on that. Trans yes upgrade to handle the power, rear end for sure 9" or Dana.
I’ll definitely go for forged internals and look at the h beam rods I want the build to last and not go boom after a couple of passes rather over build the motor than cheap out where it counts
