Um, I HIGHLY doubt the t3 is a bottle neck, the t3 makes well over 300hp and doesnt loose significant amount of effenciency until 25psi, (.63/.60 t3)... and this is on a 2.3 which flows 165cfm per port on the head.. so I dont see the t3 as being the bottle neck...

Stock internals are forged Im guessing??? or how the hell do you run 25psi on them??? I dont care how good the cast piston's are, they have a melting point somewhere...
