7M & 1JZ/2JZ flywheel compatability ???????

I have a Steel flywheel/puck clutch and TRD PP combo for sale and I was informed that it suited a 7M/R154 combo.

As I now no longer need at and am selling it, I have been asked will it fit a 1JZ-GTE/R154 oand I presume that the 2J is the same ?

So the $64 question is :

Will a Flywheel/Cutch and PP combo for a 7M-GTE/R154 be equally home behind a 1J/2J and R154 ?​

Anyone know ?

Cheers

The 7M is a 6-bolt flywheel like was said, the JZ series is an 8-bolt setup.

If you want to run an R154 on a JZ motor, you need the 1JZ-GTE bellhousing, and a 1JZ-GTE flywheel meant for the R154. All 7M-GTE pressure-plate/clutch setups will work on a 1JZ-GTE flywheel.

The difference between the 1JZ-GTE and 7M-GTE flywheels is only the bolt pattern as far as I know, an aftermarket 7M-GTE flywheel would work fine if you had the JZ bolt pattern drilled into it instead of the 7M pattern, but this would have to be done during manufacturing, and couldn't be done later on.

Good luck.

Thanks guys.

I asked on both engine forums just in case one got read first as I needed a quick answer for an Ebay sale.

You can close this thread as well now that it has been answered
