I've noticed that the CP Pistons for the MINI has a few overbore options... great, nothing new there. What confuses me is that there is a lack of CR information. I'll assume that this means that they are stock compression, and they only play in the MINI market for rebuilds where there maybe have been a hurt sleeve that only needed an overbore, and not really for N/A performance gains (although they are probably lighter than the OEM slugs).

With that said - are there any aftermarket high(er) compression pistons available for the MINI 1.6?? I'm not a stranger to going one-off with custom pistons for the cars that I've built, but I also don't want to reinvent the wheel since my MINI will likely always be my daily.

Any info will be greatly appreciated,

Thanx
