4AGZE Swap into a 6th Gen Celica Options

[Dr_Tweak]

Tuesday, July 25th, 4pm to 12am

Engine resealed with new timing belt, ready to go. In the background, the victim waits...



AHHHH! It's the black Celica of DEATH!!!



Remember kids, when swapping to a 4AGZE engine, you'll need the backing plate off the 7AFE engine. A new rear main seal is a must too!



New SPEC clutch installed and the tranny swapped over from the Celica. Yes, I know it's ugly, but around here we make things that go fast, not things that are pretty

I'm not going to release the dyno numbers on THIS swap, for two reasons. One, it's up to the owner to do that, and two, there was a hole in the intercooler that he gave me which was causing a boost (and vacuum) leak, and so he wasn't running nearly the amount of boost that he should have been, so the numbers were a little low.

However, I will tell you that another swap I did, same engine, but into a Corolla, was dynoed the same day. Stock besides an SS Autocrap header and a front-mount intercooler, it made 150whp at 9 psi.

The s/c has no problem filling the intercooler system with boost, however ALL forced induction setups benefit from shorter intercooler piping. One warning I will issue about the 4AGZE though, the throttle plate is the first thing in the intake system, so the WHOLE intercooler system is under vacuum. This presents more than the usual number of chances for vacuum leaks and whatnot.

For driving impressions, it's a much different feeling than the 3SGTE. The the 3S feels okay at first, with a WHOOSH of power coming on around 2500-3000 rpm, and holding fairly well up to redline. The GZE on the other hand has no suddeness to it, it has extremely smooth and linear power from idle on up with a slight drop towards redline (like the 3S). The power is instant and if you don't have good tires, will burn rubber at pretty much any point in the RPM band in first or second gear. It feels a lot like you're driving a car with a pretty big V6 in it.

WH96TE, yeah my partner George does the website and he's not too savvy with his spelling skills. I pointed that one out to him a while ago but he hasn't gotten to it.

The 4AGZE is marginally heavier than the 7AFE, but it would be interesting to weigh each of them and see what the numbers are. I'll look into it.
