the newer F22 is comepletly redesigned from the F20 internal completly different and the timing chain setup is different. Like john said everything else should work just fine (externally) just be carefulk with over revving S2000's have a thing with busting valves if you miss shifts ! weve rebuilt like 8 heads cause people think its a hot rod and miss shifts ! dont go to the factory rev limiter stay a lil below it !
