GQ TD42 with GU TI pump Turbo Sizes

Who knows thier turbo specs?
I have a gq silvertop with gu ti pump fitted. Timing control on a hobbs switch. Lift pump installed with the below reverse scroll external gated turbo. Pump needs timing properly I know. The tool is on the way. Yes intercooler is not yet plumbed up either and no I'm not driving it round just shake down laps. Depending on fuel screw adjustment cruising egt of 450 to 550. I don't stay in it for long. No changes to compensator or to off boost fuel screw yet either. Just wanting to see if perhaps I've gone too big on the turbo. And no I won't be using a td05 or the like. As my setup was built around a reverse scroll turbo.
Cheers
