what gains would be had from swiching out the oem fly for an aftermarket flywheel on a turbo car............is it worth the money to just buy a fly wheel or wait for the clutch to go out and buy both a new clutch & flywheel at the same time?

 

if you consider the installation cost, which is like $400, it makes much more sense to install the clutch and flywheel at the same time.

 

As mentioned if you have plans to do both you should do them at the same time.

As for the need for a flywheel with TT, not really, the engine will rev up fast enough when boost kicks in.

 

so just buy the clutch when it goes out then.................how long should the OEM one last after install of twins? is the JWT clutch good for Twins?

 

Depends on the driver, mine was replaced at 30k total miles and 10k of them with TT's and looked good and probably good for another 10k.
