Thread: p11 head On a p12 bottom end

are u going to get deep relief cuts on those pistons? for some reason i think you will be cutting it close to v2p contact but other than that it just sounds like a fun and very responsive ride.......enjoy and pics or it never happened lol

Add in a Port and Polish job with some Supertech OS valves and Competition Valve job

no this wont happen, as there is a reason why i dont want to spend much on this head as it has a crack on the timing chain gallery, and i dont want to buy another engine just for the head as these engines are $1800 au . if i can find another head i will. but at this stage i have a strong bottom end which is a good start. and a decent top end. not unless some one wants to send me a a head cheap.

i wasnt planning on as the je pistons have a decent relief in them as it is.

but i might need to look further into it.

and as per my other bmw throttle body thread pics are a must.
