Anything from a 49 to a 62 would work fine and anything up to a 62 will fit in the hotair housings. Since you have ported heads and intake and a good downpipe I would suggest the 62, just make sure to get the TB ported to at least match the inlet size of the turbo. You also need a minimum of a 2,800 stall convertor.

What might work even better is to look at the new Garett GT series turbos and find what they offer in the sizes mentioned. I've heard great things about them sounds like they spool much better for a given flow.
