Is it A-Series only? I think it should be... So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'... On 26th Oct, 2004 Tom Fenton said:

It'll work, it'll just be a pig off boost and on boost it won't make quite as much power. 8 to 8.5:1 will be better for 20psi. Fastest 998 mini in the world? 13.05 1/4 mile 106mph

Imo ideal compression ratio is around 8.0:1, capable of 20psi, so that's what I would be aiming for.
