i recently completed a GT2871RS upgrade...rated at around 400hp...definately gives it more kick, but is a touch slower to come on.
Pros: Faster, New, will stop wastegate creep u prolly have (if u have a zaust)
Cons: $$$ (mates rates are good) need to get manifold and downpipe made...or adapter for stock manifold, oil & water lines need to be made, stock ecu means only around standard boost can be used. $$$
All up mine cost around 2500-2600...tho there is a new CAT in there for 275, and manifold and down pipe were done cheaply by mate (but good quality, he is a zaust specialist)

Only options for you without going custom manifolds and the like is a Highflow CT26 or a CT20B.
Both of which are limited to around 300hp
