This is the same reply that I put on your post in the 24 valve forum. SORRY FOR THE DELAY!!
I hope I am not too late on this reply, sorry for the delay.
YES!!!! You can resurface these flywheels and more than once.
Folks, these flywheels are meaty and have plenty of room for wear. Your hydraulics move at least an inch and the clutch plate releases approx. 1/4" (gap). Most flywheels take about 10 thousandths to clean up and if you multiply that by 3 times you are looking at 30 thousandths. Think of holding a . 030 shim when you have . 250 to work with... . Yes you can reface the flywheels. The dealer likes to sell new ones.
