How to find out which 4A-GZE I have installed? - Toyota Nation Forum : Toyota Car and Truck Forums

I have bought a used Corolla AE86 with an 4A-GZE engine installed and I wonder how I can figure out which version of the engine is installed.

Any numbers somewhere on the engine I can use as a reference? I couldn't find any...

I thought there was only 1 version of the 4agze.

Did they make Stock Ae86 with the 4agze motor?

freakinbox · 06-19-2006, 01:35 AM

not that I know of

AE86's didnt come with the 4AGZE.

Really, there is no big difference between the 3 geneations of GZE engines, but i thought it had something to do with the number of Ribs, the absence or presence of a Knock sensor and/or the colour of the lettering.

I could be wrong though...

Does it have an AFM on it?? If so it's an AW11 MR2 or a Zenki AE92 (88-89) GZE. If not, it could be from a Kouki AE92 or an AE101.

^^ Thats it! I knew there was a noticible difference between 1st and 2nd gen GZE's. I just couldn't remember what it was. Doesnt make too much difference to HP tho, if thats what youre worried about...

***REN69*** · 06-19-2006, 02:30 AM

I guess not if you don't think 25hp is not a BIG difference.

The earlier GZEs were rated at 145hp while the last version for the AE101 was rated at 170hp. I can't remember if the Kouki AE92 version was rated at 165hp or 170hp.

freakinbox · 06-19-2006, 04:03 AM

the site he showed said 165 for the ae92 one.
neat thing to learn though

check the s/c pulley for a * or a x pattern on the front of it

also, if it has a yellow dipstick it's from an ae92, if it has a grey dipstick it's from an ae101

if it has a top mount (that's still mounted there) then it's from a FWD car (ie japanese corolla)...

if it has coilpacks then it's from a FWD car, if it has a distributor then it's from an mr2 (that is, if whoever put it in used the electronics the motor came with)

if there is an oil return line on the back of the head by the #4 (intake side) piston side then you have a later gen smallport 4agze.

there are noticeable power differences...... theere were different CR ratios and boost levels between different gze's

Also the later ones have oil squirters (not that you can see those).

And FYI the CR are 8.0:1 for the early ones and 8.9:1 for the later ones.

Thanks for all the information you provided, I will have a closer look at it tomorrow and see what matches

Hm... The supercharger has a yellow dipstick, and the normal oil dipstick is grey/black.

So I guess it's from an AE101?

Runs like mad so I kinda suspect it's the big one...

How about posting some pics of the car and motor dude.. this thread is worthless without them.
