Does anybody have a beefed up valve train or does everybody just use the stock stuff in turbo and built motors?
Usually I'd go with new rocker arms for any build. That is a main problem with the m20, is the breaking rockers issue. If I were to build any sort of 'hot' m20 motor, I'd have to budget in Billet rockers. For higher RPM applications and/or more agressive cam lifts, I would want to look into different rate valve springs too.
