Hey guys i am in the process of doing a 2.3 turbo ranger. I have just put the forged pistons in the engine and I am currently porting or widening the manifolds. I just got done doing the E6 exhaust manifold and got to looking at my intake manifold and just realized it is a duel port manifold unlike most of the 4 port manifolds I see.....

My question is, is there a significant difference in performance between the two manifolds and if not is there a good picture or how to video of how much I should port the dual port manifold?? Thanks guys.
Engine is out of a 91 2.3 Mustang if that helps.

On the four port manifolds they gut the upper and knife edge the lower. I would assume the same would be true for the two port. I believe the four port manifolds are more common. I grabbed upper and lower out of a junk yard for $40.
