I tried to talk on " alternative port efi intakes " and got run off like the plague.I hope someone here can relate or at least gives a flip. I need to start this build with a new intake. The Mercury Marine Intake is a good base design but, I don't think it has enough flow ? Any ideas on a custom application would be very helpful. I intend on putting the whole Boost mechanics in the bed of my '02 S-10 Crew Cab. 4.3 Vortec, 4L60E automatic, 4x4, 373 gears. I will set the truck down four inches front and rear. There are no helps on the S-10 sites, way to one track minded.

 

very nice project, one of these days i will do a turbo 4.3 into a 3rdgen.
few years ago i even bought a block heads/pistons and rods to start the build.

as far as port injection u have basically 2 choices marine manifold, or u can cut down the stealth ram ( i belive its the stealth ram)

other then that u can get a custom manifold from hogans but they are exspensive.

do they offer any single plane carb manifolds? u could covert one like the v8 guys convert the vic jr's for efi
