steve, dan root seems to find running 6's for far less than that even factoring the exchange rate. where he looks, i have no idea, but he finds them.

two ways (at least...)

2,7 (90mm) pistons on the 66mm 2,0 stroke is the "big bore" and somewhat easier way, if you have a source for pistons, because otherwise you'll get about 6:1 (good if you have a turbo, i suppose...)

or you very slightly overbore 2,4 cylinders to - i forget - 86mm? you still need pistons...

the factory did it both ways. nowadays, very high compression 2,7 racing pistons can work well with otherwise basically stock cylinders. you'll need to have the heads opened up (or use 2,7 heads) and of course have the case spigots opened up. and add piston squirters, without which Nikasil cylinders won't last very long, and do something about strengthening the rods and we can onlyhope you have a counterweighted S crankshaft...

pretty easy, actually...

i think if i had an aluminum 2,0 case i'd build up a "Baby 935" engine. for a 2,5 you'd probably be money ahead to just start with a 5R 2,2 or 7R case...
