This is an awesome build. The porting and polishing would normally make the power peaky but I see that the standard valves are being used so that shouldnt be a problem. Porting and polishing doesnt give big gains in turbo applications like it does with normally aspirated engines but every little helps.

Keith is hoping for around a 50 bhp gain from the head and re-calibration.If it makes that much is will send my head off straight away.
is it similar gains across the rev range or is it mainly peak power gain?Sounds awesome so far
