ok my 7afe is dohc but the head is so small and so little hp i want 2 know the gt motor it has like 130 hp will it bolt up 2 my st will the wiring harness hook up are there more parts 4 it is the head any biger can you get cams 4 the gt motor i thank anyone who helps

it is not a direct bolt in.
youd need a complete engine set, harness ecu and tranny, to even begin to think about doing it.
not at all worth it.

There are some guys on here who have built up there 7afe's. It might not be too bad of a motor if built right. Look into the option of putting a 4age head on that motor. A guy you'll want to talk to is Nik. He's done a couple. There is the option of the 4age motor too. It has a lot of potential, and comes with about the same hp as the 5sfe in some years.

or more in the 20v
