Having a quick look at the turbo specs of that kit (60-1 I belive)
You would have to be pretty big on the exhaust housing AR to get close to that sort of hp.
Injs are WAAAAAAAAAAAAAAY too small as is fuel pump.

What you runnign ECU wise?

The turbo will a 60-1 Hi Fi with a 62-1 wheel.

As far as the ECU I will be runing TurboXS UTEC

On the exhaust side I will be venting the WG and on teh exhaust I will have a VES system which basicly vents the exhaust under boost

As far as the injectors and fuel setup, why do you say they are way too small? If you would calculate fuel requirments based on a BSFC of 0.61 and IDC of 85% you would need 1000cc with an FPR of 1:1 ..... Could you please explain...

You state TURBO not TURBOS
Typo or you only have one? If one, no way in hell you're going to get there.
IIRC correctly, the kit comes with 380cc injs.
Most you'll see out them with a bump in base pressure is around 450-500hp atw.
Walbro 255... no comment.. 2x Bosch 044s would be my pic. 4.Xl/min at pressure each..
1000cc injs.. yes.. but I don't/didn't see that on your list

Upgrade the pump/s and throw the UTEC away (sorry) and I think you're on the way to your targets.
Whats the AR and frame of the exhaust housing?
Exh wheels trim?
