Flywheel size

jrhendo

Hi,

Does someone have a 140 flywheel handy (8 bolt if it makes any difference) who could measure the diameter inside the ring gear?

Background: I run a Toyota gearbox on the rally 144 and need to get custom clutches made up. If I could fit a complete Supra clutch kit after redrilling the flywheel, I can get that a lot cheaper in the US than getting custom stuff made in Australia. And it's a bigger clutch. On the last long rally the clutch copped a lot of abuse and was very tired feeling at the end.

I'm currentlyin the US and could bring one back with me if it looks like it might work.

Regards

John

It just so happens that I got mine from the machine shop the other day.

The w58 disc upgrade has been covered before, I use a falcon 3.3 pressure plate with the exedy disc with the correct centre spline, from memory it ends up being a 235mm disc and an organic unit is $200 for the disc and cushion button or button disc is 450, from my research, prices online are not actually cheaper. Anthony Hyde's website cover's this conversion and the 8 bolt b20 uses different flywheels to a ohc Volvo motor but they are interchangeable. 240mm is biggest you can fit on the clutch surface.
