. . . about liners, reboring and some info about cams, perhaps Ian can write a piece for the technical section about how to convert the humble M20 to a 700+ cc engine (sans liner, I guess, or does it also have to start as an M21?).

Hi John...It's a very simple conversion in its most basic format though there are benefits in going a little further...

I'll try to find some time to write up a piece for the 'Tech Section' as you suggest...Ian

Hi all, some machinist once told me that when using a liner the bore should be a couple thou more, as the heat transfer between the liner and the cylinder is never optimal, and some extra clearance is needed, anyone ever heard of this??

Cheers,

Lex

ps, an article would be nice!!
