3s-gte vs. 1mz-fe flywheel differences

[zoni]

Anyone know what the bolt pattern differences are between 3sgte and 1mz flywheels? I need to start looking for a carbon clutch, and i cant find one for 1mz. I know the tranny side fits with the 3sgte, but need to mate it to the 1mz crank. Or, if Justin knows where i can get one for a v6??

Those who are looking at putting a manual trans behind a 1ufze(4.0 V8) are going through the same thing; the solution is to re-drill the crank pattern after welding the existing holes up in a 3s flywheel, make sure the chamfer on the ring gear is facing the starter, may need to modify or replace the ring gear.
You could probably get away with a near stock clutch for that motor and a lighter vehicle, have my doubts about a clutch that small being used behind the 1ufze, and in a near 4,000 pound vehicle however.
I don't know what the difference is between the 3s clutch and the six cylinder clutch, or whether you can use the parts together.

i cant get away with a regular clutch... i will have too much power. i know what i need. i am not a noob.

There is also an aftermarket flywheel available for the 1MZ-Fe engine. Fridenza makes one.

The bolt pattern should be the same between the 3MZ, 1Mz, and 3S series engines...
the difference is the backset. How far the plate actually sits from the front face of the engine.

i have a fidanza already. look in my sig.

i want a twin plate clutch and that exedy twin plate for 1450 comes with a flywheel. but they dont make that clutch for v6, so i have to weld the holes and redrill for the v6 pattern. on the v6 there are 8 bolts and the 3sgte there are 6.

Only the first generation models of the 3SGTE had 6 bolts. The later models had 8...

ohhhhhhhhh k then. maybe i will try my luck with the later one... maybe it'll just match up. but the bolt radius could be different too.. i dunno we shall see.

Did you try to contact Daikin Clutch USA (EXEDY) to get an undrilled flywheel or have them copy the 1mz-fe bolt pattern?

(sorry, just realized how old it is, but im still interested to see if anyone has fit a twin disk clutch to a 1mz-fe)

I HIGHLY DOUBT that. All 3SGE's are 8 bolt, the only 3S ive seen with 6 were the pre-90 3SFE's.

i cant imagine a 3SGE would have 8bolt while the 3SGTE would have 6, it just doesnt seem right.

i know they had a 6 bolt version sometime in their life cycle... ive heard recently of someone getting a clutch made for mr2 and it bolted up directly to the 1mz with no modification. dont know what year it was made for...

i wont be doing this clutch just yet... im going to wait for the motor to be built first.

They did use a twin disk in the 1mz-fe buildup in TURBO magazine. I remember that they had to space the transmission to get it to work properly but never really went into detail on how this was done.

A 3SGTE flywheel from an MR2 WILL bolt up to the 1MZFE engine. It's been done by a mate of mine who was going to put a V6 in his MR2. He changed his mind and went for the Beams 3SGE instead, and I ended up buying his flywheel, which will be going onto my 2VZFE, which, has the same bolt pattern as the 3VZ and 1MZ engines.

Go for the 3SGTE one, itll work fine in terms of mounting. The only thing i'm not sure on, is the starter motor. You may need to make up an adaptor plate to bring the starter out further if the offset is different, but i don't see why it would be.

Good luck

(check out my Flywheel thread, and you will see the pics of it.)

I know from first hand experience that the bolt patterns are different for at least some 1mz-fe and 3s-gte. Perhaps the american 1mz-fe or 3s-gte are different but they definetly are DIFFERENT.

[JetspeedCamry]

The MR2 3SGTE Flywheel (at leat the one I have...) only takes a 9" clutch. The V6 one takes a 9.5" clutch. That is the biggest difference I know of. Bolt pattern is all the same.
Seeming i'm using this thing on 2VZ, which doesnt produce too much torque, all should be well using a 9" clutch. However, on a 3VZ(especially) or a 1MZ, you make experience slippage.

[gLok]

Im using a 3sgte clutch/pressure plate on my 1mz-fe, however the bolt pattern of 3s-gte flywheel is different. We need to find out which years are different and which are the same OR if the overseas 1mz-fe uses a different pattern on its crank.
