Thinking Blouch 2.5xtr with 8cm housing....maybe 1.5xtr depending on the differences between the two, will have to speak to Troy....all depending on how much build costs are on Tuesday.

I agree with Nick here....forge it now that its getting opened, don't want to only do head gasket then in a few months time pop a cadbury piston
