914 flywheel vs a bus flywheel, any differences? Options

[malcolm2]

I sure can’t see any.

Building a 2.0 from a 1.8 from a 914 for my 72 bus that came with a 1.7. Have both flywheels. I did not label either. The 914 was running when removed so it must be the shinier one. The bus sat in a field for 10 years. So much moisture under there that the magnesium bell housing deteriorated.

Anyway, both are 210 mm. Some vendors say their 914 FW won’t work on a bus and visa-versa.

Anyone have more details?

My car had a 228mm flywheel when I bought it. Idk at the time, but I found out when I went to do the clutch. If my memory is correct the 228 mm flywheel is lighter than the stock 914. By the way, that donor crank you have looks like the flywheel came loose when it was in service.
