Pre 10/92 clutches needs the 22RE flywheel and clutch, all 22RTE's, and post 11/92, uses the 22RTE flywheel and clutch.
The non turbo clutch/flywheel is 8 and 7/8" and the turbo clutch/flywheel it 9 and 5/16". They aren't interchangeable, you will need a turbo clutch and flywheel, or a non-turbo clutch and flywheel. Can't mix and match. But you can put the turbo clutch and flywheel combo into any 22r series motors, and bellhousings.
