I was wondering if there was anyway to port the intake manifolds on the 2.8L crossflow system, i was looking at my friends tonight and it seemed like maybe it could be ported like the TPI systems often are and therefore make more HP with the expense of already low amount of torque. anyone tried this or any info?

well, the reality of it is that the MFI on the 2.8 is actually VERY similar to TPI, it basically is TPI cept a lil different name


now i cant take my machine shop class in college for a whole nother year.....but when i do, i hope i have the 3.4 installed


when that happens, i'm gonna pull the head and intake and port them suckas

I am half way done the port and polish job right now. I've got an open post on the topic, hopefully a lot of input will start coming in there.

BTW, the v6 doesn't have a "crossflow" intake system. The upper plenum may look that way, but once the air is in that upper plenum, it goes straight down to the manifold. Think of the 2.8 intake as identical in principle to a TPI, except instead of the runners separating from the plenum, the top half of the runners are attached to the upper plenum.
