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

the swap is not " bad " for a ST, some people will argue that " its not as powerful as a 3S " and that's true, stock per stock the 3s is a stronger ( HP wise ) motor, but both have good potential. if you plan on keeping the 4AGZE stock ( rated @ ~ 165 hp at crank ) make sure the power will be enough for you, after all us ST guys, we get the joy of ~ 90 hp at the wheels on a healthy engine lol. the 6 speed tranny option is more for bragging rights, I search on different forums and this tranny is weak, doesn't take abuse and can't hold extra power, the tranny is great for N/A engines, a better tranny IMHO is a 5 speed with a hydrolyc LSD from MR-2 and some levin.


I was reading on a 4AGTE set-up using a 4AGZE + silver top intake manifold and custom exhaust manifold + HKS cam shaft + HKS cam gears + supporting fuel up grades, someone on Australia got 245 HP at the wheels. That's not bad,

everything needed can be had for US$1500.00 and if you want more power work on a custom turbo kit, I'd be happy with anything over 200 hp at the wheels, but it'll be some time before I can do anything like this to my car. too much going on in my life at the time.
