An OEM replacement will probably last a bit longer than your old CSC will, but I would go aftermarket, as I still don't trust a CSC that fails even once under normal driving.

My opinion is that you should go with a clutch and flywheel kit rated for 500 torque, and do the CSC replacement aftermarket as well. That way you can be confident that your kit will not fail until you start doing boosted miles. You might lose some gas mileage though.
