Hi Dave,

Do you remember what that flywheel weighs? Was it the same diameter as the flex plate, or was it smaller, like the non-turbo manual trans flywheels? Did you remove all the disk mating surface to reduce weight, or just enough to mount the damper plate?

I've got an aluminum manual trans flywheel on the shelf, but it's slightly smaller in dia than the flexplate. Wondering about weight comparisons, mounting, etc.

In more general terms, the flexplates seem to have a rather checkered past even in the car. I've got one that came off the car cracked.

Neil, great job on getting your gear-box into production.  We sure need it.

Hello James,

 

I have a stock 13b ( estimated 150 hp) with RWS equipment. I used a racing aluminum flywheel and removed the steel clutch facing. Then I resized the RWS splined hub to fit. Basically I copied RWS by making a new plate and riveting on the RWS splined hub to my new plate. Because the new plate is a smaller OD I used 6 bolts instead of 4. I used the same durometer rubber cushions.

 

Thanks,

Dave Williams

Dave, do you have a recommendation for a lightweight flywheel and flexplate/ damper (brand or type) for a 250hp 13b? Thanks, James Whitehurst

Can anyone confirm which flex plate fits the RWS redrive?  I believe it comes from a 92 model RX7. But is it from an automatic, manual or turbo model?  All are different apparently.

Thanks  Neil.
