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

I would use a small port because of the MAP, and younger motor, but I think most people prefer big port heads because of the lower C/R and better flow ( don't quote me on the flow preference since I don't really know the differences on flow from one head to the other )

other random things I've been reading / thinking
4agze's have forged piston in stock form, that's one of the reasons why these motors run a little rough when cold until they're up to temp. so this engine comes built for good daily power on stock form, our only problem is the tranny, the 6 speed tranny is not an option for power builts, they are wayy to weak. Unlike the 3S guys we don't have a E153 option and the stock ST tranny's are not the best for big power applications, our best chance is with the C-52 that comes on some levin and JDM MR-2s with a hydrolic LSD, and a big turbo so we don't boost too early to lose traction. I was gonna swap my car before paint but the paint on my car is in such a poor condition that I can't do that, I'm gonna be painting the car within the next 2-3 months and if I don't get a job I just applied for I'm gonna use the time to swap the car before Sept when I'll be back to school.
