Can anyone tell me the difference between a non turbo flywheel and a turbo flywheel??? on a BA manual ...cheers...

N/A - 10" flywheel, 10" Self Adjusting Clutch (SAC), 26 splines on clutch plate.

Turbo - 10.5" Flywheel, 10.5" Non-SAC, 26 splines

You can run a turbo clutch behind the N/A motor by using the turbo flywheel. Can't mix and match bits due to the SAC nature. CSC is the same. N/A box will bolt up just fine with turbo clutch and flywheel.
