One for the techies (?!)

[Dave (Kent)]

In the days of yore we used to overbore mini engines and use Triumph 200 pistons to achieve 1400 cc (ish).

With regard to a 3 brg 2.25 petrol series engine:
Anyone know the max overbore using std LR pistons?
Any other pistons fit that would enable bigger capacity increases?

I know - just buy a V6/V8 - just want to work out whats possible......

Also, what 's the formula for psi in relation to compession ratio? (Or what readings should I get for 8:1 and 7:1 compession heads), and how much needs skimming off the head to gaet to 9:1? (Used to have a book with all this in, but damned if I can remember which one it is...)
