Default gt28 or gt3071

im thinking of upgrading my spec of my 2wd cossie. i think the only thing to upgrade is the turbo and map.
at the moment my turbo is limmeting my power (t34.48) its running with the pipe off the accuater at only 1.5 bar which means its flat out. no play in shaft etc.
the rest of my spec is half decent to see over 400 bhp i think.
woosner forged pistons 8;1 comp
ported head and manifolds(4x4)
10mm spacer on inlet (4x4)
bd14 inlet cam, std exhaust
2wd exhaust manifold
rs500 cooler 70mm pipes
3inch exhaust and good filter etc
siemens 83lb injectors.
the car is a good stage 3 but just want more for the summer, i was thinking 2 bar boost on a gt30?? any one recomend them on a cossie?
also who is the best people to supply me with one with cossie accessorys to make it fit.
any info of discusion is apprieciated

3071s seem to be doing very well fella and your spec would suit one very well, speak to Mark Shead about the turbo, he's done a few now and rates this conversion very highly...2.3bar boost wil be nice...
