4A-GZE Clutch and flywheel compatibility

[BLSTIC]

Hi all, it's apparently clutch time, if no-one buys my car. And I can't for the life of me get my head around which clutch I actually have in the car. The build plate says 4A-GZE and E58-474. It's an 89 model, air-flow meter, DLI, bigport.

So have I got the 250mm, 253mm, or 225mm clutch? I'm assuming that the smaller clutch was for lowly n/a models, which leaves me with the 250 and 253mm items. Which is close enough to look the same but not close enough to bolt up.

Any help please?

I *could* just get the 70% remaining 8-puck clutch I was offered but I think button clutches are about as sensible on the street as a guy in drag. Sure it's funny to watch but you sure wouldn't want it to be you...

Oh there are two clutches exedy list for the car. The TYK-7411 for 250mm pcd, and the TYK-7501 for 253mm. I can find both online, but don't know which I have

[wiso]

no, 225mm was a supercharged clutch, it was in the AW11 4AGZE. Lowly N/A models got the 212/215mm clutch

As for which you have, god would know without pulling it off. at a stab I would guess 225 like the AW11 since yours is still an early GZE, but its only a guess and you should i no way buy one based on that


edit:
a quick search saw this http://www.ae86drivingclub.com.au/fo...ctory-flywheel , so if this bloke is correct then an AE92 one is the same as the AW11 item

[BLSTIC]

Well I did some more searching and I discovered that if I go by the xtreme website I have

AW11 MR2 Supercharged KTY23016-1A
AE92 Levin GT-Z 5/87-9/90 KTY23029-1A 250mm pcd
AE92 Levin GT-Z 10/90-6/91 KTY23018-1A 253mm pcd
AE101R Supercharged KTY23017-1A

Given that I know my vehicle is an 89 model (based on big-port with air-flow meter) I should order the 250mm item. It has a wrecker gearbox (or maybe the gearbox was tagged for wrecking but narrowly avoided it before importing) So that could mean anything...

But I'll just order the 250mm part and if it doesn't fit, can I get my flywheel modified to suit while it's being machined? Or maybe another flywheel? The price difference is huge between the two clutches (like, $200-300 depending on where you get each one).

supercharged flywheel 225mm


n/a flywheels

[BLSTIC]

The issue is that there are two supercharged flywheels though The difference being a cool 3mm...

Thanks for the pics though

you have there saying 250 and 253mm PCD, that means the mounting points. so technically, [edit] I was thinking it was like the NA flywheel where you could rotate the bolt patterns and redrill, but looking at that pic, no it does not look like you can move the pin locations. So no modifying the flywheel would be out of the question on a budget.

going off what Nickjoe said on the AE86DC

nar they are 224/5(aw11-ae92) or 230(ae101). Was measuring up the difference between the ae101 and ae92 4agze flywheels last week, both actually had the same clutch face size however the ae101 had slightly larger bolt pattern/pin location for the pressure plate(probably like 1mm or two difference).

if your ordering the 250mm item (225plate) i would dare say it would be pretty safe.

IMO smartest thing to do is drop the box and measure the clutch plate diameter. you gotta pull it apart to do the job anyways, so why bother waiting to pull it apart and find out you've bought the wrong thing......

Goes from a single day job into a 2 week job while they get your obscure clutch kit from a warehouse somewhere
But your right, probably the safest and smartest option if you afford the downtime

Hmmm... one last question I swear

What's the spec for the height of the posts that the clutch mounts to? Because if the flywheel surface gets ground and tter posts don't... Less clamping force... I would hardly be surprised if that's what has happened.

Car is sold. No need to answer, though out of curiosity I'm interested

Not sure about Yota's, but in regards to other cars I have dealt with (a star badged AWD make in particular), as long as the clutch bolts up to your gearbox, and the flywheel matches the clutch, it shouldn't really matter what diameter either are (within reason though of course, since diameter is related to pressure plate clamp load required etc.)

So theoretically if you were to find ANY E58/4AG clutch/flywheel combo, it *should* bolt up, unless I am missing something here.

Anyway, best method I would use is the EPC. Check the part number for the AE92 clutch disk and or flywheel, and find what other models it matches.

PN #31250-17030, OD=224, clutch disk was also used on the GZE MR2
PN #31210-17020 , clutch cover also used on the GZE MR2

PN #13405-16050, flywheel also used on the GZE MR2

Your chassis code would have been ACMXR, and provided everything in there was stock, the EPC does not lie about what parts fit in there.

No idea about post height, but I'd imagine if it being reground affecting the clamping force, then something very wrong is being done during the regrind.
