taken from the "articles" page of the toymods index page.
"F - Narrow angle Twin Cam (economical head)"
Narrow angle meaning the ports and everything else are in a different poisition,
"G - Wide angle Twin Cam (sportier head)"
If they were exactly the same, why would toyota feel the need to engineer two different heads?
They may be similar, but the wider angle head is obviously better suited to performance application.
7afe is 1.8 litre isnt it? i assume its just a stroked 4a? i know nothing about these engines, but, it seems simple enough to swap the heads and ecu over, seeing as they *apparantly* are bolt up.
the 7afe/4age could probably only put up with 6-8 psi of boost on high compression setup before is fucks up, whats the point?
Buy a 4AGZE, swap it in, apart from the ecu, everything should *glide* right in.
