heyo-
so i just bought a 3FE injection setup and head this morning, i am STOKED! a stroked 3FE is on its way!
BUT-
in pulling the head out of my cruzah and taking a cursory look at it, i am a little shocked to see that the thing looks almost exactly like my late model ('86) 2F head!
if i could put all the EFI stuff on my 2F head, i would prefer to. the head was ported and polished, compression is now about 9:1, and the valves were cleaned up nicely. it would save me getting a 3FE head gasket and new exhaust plumbing too, saving me lots of cash.
i looked around a bit on the various archives that i know of and have found that the 3F (carbureted) was available in 1984. i have also HEARD that a new late model 2F head from toyota is the SAME as a 3F/FE head. i have also seen it mentioned that the compression in late 2F motors was higher than in the earlier models, implying there was a change in combustion chamber/piston choices.
other than the volume of the combustion chamber, are there ANY differences? if all mounting studs are the same, all ports are the same, i would much rather cut the project down to simply a wiring nightmare rather than an additional head job...
thanks for your time and knowledge!
