Currently running smaller ports (then ones in the pic) with a T66 .96 a/r p-trim. "IF" I am getting to much back pressure with my current ports I know this turbo will choke these ports at the top end. Thinking/wanting to purchase a new turbo but unsure which direction I should go, Larger 1.15 a/r with a p-trim wheel or go with a .96 a/r q-trim? The place I am thinking of buying the new turbo suggest going with the 1.15 a/r p-trim. Will staying with the smaller wheel help spool the compressor wheel and the 1.15 a/r help relieve some back pressure? I like the .96 a/r q-trim because my manifold is not divided and I think the ports in the pic should spin a q-trim wheel. Looking at a T72 compressor side and boost pressure above 20psi. Suggestion!

thanks
