I've been debating turboing the 6 port NA I have wondering if I should stick with the stock steel flywheel since of the more storred mass it would have or just keep the AL one and get a different clutch for it maybe. stronger than what I would need for the steel one.

 

For what you are worried about the flywheel material makes no difference. If the clutch and pressure plate will work with the stock flywheel, it will be fine with an aluminum one.
