Default What turbo should I buy? :-)

Evening guys,

Well, after much thinking I've decided to upgrade the turbo on my S2!! I know this subject has been discussed many times with a lot of people strongly leaning towards having one spec'd for your specific application etc.
Now I'm not adverse to doing that, obviously it will cost a bit more, but just thought I'd check to see if any of you regulars have any suggestions for me...?

Ideally I'm after something that cuts in at 2.5-3k and holds boost nicely till it runs out of revs. I have had a T35 on an old RS I had and that seemed just the ticket compared to the stage 3 T3 (360 bearing, cut back blades) that's fitted to this one when I bought it. So time to change! I'm looking to break the 300bhp barrier ideally, so here's a snap shot of what she's packing so far:-

Some info for you on the turbo,

Bottom end is a standard 2.0 zetec end with the under piston oil jet sprays bored out to 86mm with cavalier gsi forged pistons from the xe engine, standard zetec rods with the little end machined out for the gudgeon pin from the xe pistons, very ported & polished head etc, arp con rod bolts, high pressure oil pump(using stronger spring), new bearings, sitech racing multilayer steel head gasket and head bolts, Inc flushed valve guides, rpm 36 cam shaft same spec as piper 285t2, adjustable vernier pulley, grs cooler, airtec rad, chipped etc, -31 actuator.

That's about it engine wise. Now before anyone points of he fuelling being an issue, I know. I've got an MF2 5th injector system (with 803 green in there) sitting to go on when the turbo does so it can all be set-up in one hit. I know not all are fans of this method, but it's the route I've chosen, for now

So any advice on what turbo would be awesome

Let have em, lol
