doing a rebuild on 4AG MR2 motor with 42 mm crank to replace my GTS motor (87) with 40 mm crank, need to know if my lightened flywheel will fit on 42 mm crank?

It should, as both should have 8 flywheel bolts. If it was going into my car, I would have the bottom end balanced (those MR2 internals + lightweight flywheel). But I'm no expert...

He should include the crank pulley, AND the pressure plate too

thanks guys, the shop is doing the long block assembly I'll make sure they balance it all, getting psyched, ordered .20 over Wiseco pistons 10.5:1 , have some mild HKS cams, should be a sweet little motor
