swap

[WHY_NOT???]

ok well ya'll I got a few techy ?'s and let's just say mad fun

ok well i have a 89' AE92 SR-5. So i have the stock 4A-f motor in it and the stock tranny as of right now.

I am looking to do a 4A-GZE swap into it, got the motor and ECU and wiring harness. I think the 4A-f's tranny will bolt up so i think i'm set there.

now the fun part is what else exactly would i need to do this swap and what are some binds i might run into?

You'll need a hood scope if you keep the top mount IC. Exhaust manifold or header. Reroute intake. Very basic.

Good EFI Fuel Pump.

Flywheel and Bell housing-The GZE uses the 212mm Flywheel and your 4af uses a 200mm flywheel and the bolt pattern is different between the 4af and 4agze as well.

You will also need a oil pressure sensor that will work w/ your dumby light in the dash since the gze sensor is for a gauge.
Just ask if you have any more questions.
C-YA!!

you sound liek u actualy know some stuff lol, but yeah anyways i have a guy bwho is a toyota 4 cylinder guru and is pretty good with MR2's and corolla's ho is gonna help me and what not so im sure he will knoiw the stuff to do but it is defantly possible not toooo outrageous of a swap to do right?

Get a oil pressure gauge package from autometer

Unfortunately he's a little bit off... =[
The 4AGZE uses a completely different tranny, but the C50/52 that comes with 4AF/7AF/4AG's can bolt up if the correctly sized flywheel is used. The E51/E58 trannies that come on different versions of the 4AGZE are much stronger and are slightly different. The problem is the 4AGZE flywheel which is 224mm. That flywheel is physically larger than the typical 4AF/7AF/4AG flywheels which are 200mm/212mm. If you're gonna use a C50/52 tranny, you must use either a 200mm or 212mm flywheel. These flywheels are physically the same size with different sized contact surfaces. You must source one of these from a 4AGE because of the 8 bolt fly vs. the 4AF/7AF's 6 bolt flys. I don't think the 4AGZE flywheel (224mm) will fit into the C50/52 tranny.

i think you'll be snapping your axles everyother day if you run the 4AGZE with the C-series axles... the E58 axles are much thicker.

likewise, the gear ratios on the E58 are taller compared to the C-series... which means you'll be running out of revs fast if you use the C50/52 with the 4AGZE.


on other things, not sure if you're running a stock carbbed 4AF... if you are, you'd need to change your fuel pump for one that suited for an EFI engine. also, the radiator for the 4AFE has the top water hose coming from the middle... the one for the 4AGZE should have the hose coming from the side.

You'd be suprised, VooDoo. They're a lot stronger than you think. Several years with a HKS overdrive pulley, and they're still fine.

[VooDoo]

how about the gear ratios? don't you run out of spin at top speed?

[4Aaron GE]

With the C50, you'll never reach top speed. I worked it out mathematically, and it's somewhere around 250+km/h

ok so i need to get a 4 age flywheel and bolt that up to the motor and then it should bolt up to a 4a-f/4age tranny?




yeah and btw fuel pumps and guages etc..., dont worry i got all that covered, i am just woried about this whole tranny situation really and what is the deal with running out of rev, bad gearing?

[4Aaron GE]

The GZE has lots of torque, so it'll be okay with the 4A-F gearing.

hmmm... interesting...was thinking of fitting a C52 with LSD in mine to save some weight...

More or less... yes. Any version 8 bolt 4AGE flywheel should work. Just be sure to use the clutch that matches the flywheel... 200mm/212mm...

Just remember to get the C52 that has the characteristics that you want. The C52 from the AE92 GT-S has lower gearing than the 7A-FE C52. The one that my brother and I are using is a C50 from a 4A-FE setup.
