Ultimate N/A M20 racing engine?

[digger]

yes, you can make S50B32/S54B32 power....the most important part is the cylinder head modifications

What are the realistic limits of an M20 ?

If you put 84mm crank, 12.5 cr pistons, H-beams, Rama roller cam kit, ITB's and proper headers... what can you expect about DIN-power from crank ? Anything like Euro S50B32 ? S54 level might be out of range ?
