I was just piecing together my own turbo kit based off of a Full-Race TS T4 manifold and began researching people using any of the Borg Warner Airwerks series turbos. Come to find out no one really runs them and all the focus has been on their EFR series.

From a budget standpoint, a S300SX even with a full race mani is still much cheaper than the pre built kits out there so what gives? I know full race has one video of an X dynoing with an S300 but that is about all the info I've seen on this setup.

So.... Anyone running or know anyone running an Airwerks turbo setup on an X? Also any insight into why no one runs them would be awesome.
