I have a GT2860rs on mine, change the compressor wheel to an after-market GTX2860 units has a -48 housing on it's on boost by 2600rpm and by 3000-3100 it's 24psi.
A very drivable car tyre shredding low-end fun, instant torque. Not the most bhp , 334bhp 332 pound foot but a lot of fun and driving pleasure.


Cheers.

Tim.
