I have a straight cut at the moment but it needs a rebuild as its crunching into second. But I have a newly rebuilt helical box I could use. Wasnt sure what would suit the turbo as the straight cut is close ratio and keeps it in the boost. Was the metro turbo a different gearset to a standard metro/mini or was it the same

It was the same. It had a 3.2 diff and boost was limited to 4psi until 4k rpm and then it was 7psi. I might be wrong about the revs but i know it was limited and then went up
