BMW 4 cylinder heads - street to race

[Guest Anonymous]

8v to 16v. A lot written about the various cylinder heads, pistons etc., I am working on a post of the letter etc., and pics of the ALPINA A3 head I had prepared by ALPINA years ago (subsequently sold) and as a precursor to that put together some very (very) basic info on the 121/121Ti, E-12, E-21 2.0, M12 and Schnitzer cylinder heads. Twofer wednesday.

Very good information. So any head could be converted to Alpina A3/4/4S type head. All you need is the bigger valves and matching pistons. As far as i know JE pistons had this type of pistons for 2002.
