Not the Rover T25's.

I went through a few of these, laggy and not really suitable for high boost (read they just fall apart after a while)

I personally use a GT Tuning's HE5B which is a T25 sized turbo and it's very responsive (i run 22PSI)

What you got to deside is what boost you want to run, how you want the engine to respond and also whats the spec of your engine already

I have run t2 , t2.25 , t28 , and VNTs

All about your engine spec , and what boost you want to run as Marky Mark said.

Every turbo has a different characteristic !

If you sticking with standard cam then i wouldn't go any bigger than a full T25, maybe go for T25 with T2 rear housing this will be nice and responsive but still be able to flow some boost
