here's the email he sent me guys:
"Kev
The hx30 will do 400bhp no problem and will spool very fast between gearchanges,I would expect full boost in the 3500rpm area so a good useable rev range there as boost will start building below that level.for direct fitment you will require a t3 flange adaptor for your existing manifold or a t3 flange manifold.I'm guessing you want internal wastegate?this makes fitment easier but if not you will require a t3 flange external gate manifold.the hx30 would be ideal for your situation
Thanks
