I have a b18a with JE 9.1:1 pistons and Crower rods, stock bore. My goal is to make 350 and 300 on no more than 18psi. Which turo would be most efficient? I would like a Precision possibly or a Garrett maybe one of the new GT series. PLEASE SOMEONE HELP ME OUT. Oh yeah Hondata will oversee operations. Thanks fellas. Peace.
