I would like to know if it's good or not to run a turbo setup witht the T1R crank pulley and the T1R drive pulley set. Does it affect the performance ?

I know that lightweight flywheels are not the best for a turbo setup...but I wanna be sure for the lightweight pulleys...

Why do you want to run the T1R pulley set? Is it already installed?

already there...could those affect the F/I gains ?

Unlike a wheel, tire, or flywheel, a pulley has a relatively low polar moment of inertia. Swapping it out with a lightweight unit is going to yield very minimal gains. So long as the pulley is functional and has no problems, I wouldn't get rid of it, however don't expect anything special either.

Good ! I just don't want to loss power with that upgrade.
Thanks !

Why are lightweight flywheels bad

I wouldn't be so keen on that crank pulley. There is a lot of discrepancy against using an aftermarket crank pulley on these cars. There is a harmonic balancer built into the oem crank pulley as it has rubber impregnated into it to absorb harmonics of the crank. I ended up selling my pulley set cause a bunch of people warned me against it and it wasn't confirmed if it would cause engine damage over time nor did it give any significant gains
