A T66 is rather large. The sizing of the turbine and A/R will be critical, especially since it's made to flow more. Typically that would mean the surge line is higher. Too small a turbine may cause boost to occur in front of the surge line. With a larger turbine, expect more lag. So I would probably reserve this turbo for a high boost, high RPM application where response is not critical.
