Kerry,

300D flywheels are rarer than chicken lips, but a 300d from the earlier models will work. At least one guy on this forum is running with a turbo using a 240D flywheel.

I personally ran mine for 18 months with a 110 flywheel aaand had no apparent problem. By all means search for the 300D and whichever one you use line up the balance marks on the flywheel with the one on the crank.
