4AGZE Swap Options

[mikecelica]

I've been planning on turboing my st for a while now, got all the parts, but after going through all the costs with parts and labor I've come to a total of $3100, which I think is waay too much for 40-50hp (If even that). I wouldnt be getting much horsepower, plus risk damaging the engine, and say goodbye to the toyota reliability. So Im thinking now of just swapping in a 4agze, Ive been reading up alot about this and what i wanna know is why people think its such a difficult swap and that only few people have attempted it? Ive gone through this with a mechanic at toyota dealership that I work at. And he too says its the most simplest of swaps. All i really need is the engine,ecu,wiring harness,4age flywheel with using my 7afe tranny and same motor mounts. Thats pretty much it, unless I put in FMIC, but I've heard they benefit more from TMIC. The 4agze from the Levin from has about 170hp at stock psi (7psi) and at full boost (14psi) it should reach around 190hp or more with some pulleys and an safc. Plus another advantage would be that this engine was built to handle boost so its alot more safe than a 7afte. This mechanic has a 88 corolla gts with the 4agze and an mr2 4agze and they are faast. So I just wanna hear some thoughts on this. thanks

Everyone I have asked says use the large port head for a turbo build
from what that shows, I don't see why. The small port comes stock
with bigger injectors, and makes more power than the large port.
To me that says better flow.

think of it this way when you port and polish a head for more flow you widen it
the big port head is bigger by like 25% stock to stock with the same port
so when you turbo and you want all the flow you can get so starting the big port is the way to go

now this all depends on your power goals
