What kind of flywheels to M20B25 have ( i.e. single or dual mass)? I think there was a crossover point from single to dual but it was something i read and don't know the real truth. What is the mass of each? Do cat equpped cars have different flywheels? Are they easily interchangeable or are spacers and clutch changes needed?

Cheers

single mass on all M20

the A/C equipped cars have a 1.3kg lighter flywheel other than that, no variations I'm aware of dude

Dual mass are crap, expensive and dont last when pulling loads. Have a normal one anyday.
