Hello everyone.Has anyone ever used a turbo deisel manifold on a a m20 motor? If so what stud do you on the flange do you drill or unibit out.Also, any pictures or related information on the subject. Thanks again . Bmwe21e30 at firstname.lastname@example.org.
I think what the gentleman is trying to ask is... Why in the hell would you want to do this in the first place man? WTF is wrong with the M20 manifold and how do you propose to mount a throttle body to a diesel manifold which would not have one? Also a turbo manifold would not be a good choice for a naturally aspirated engine in any application! It will not provide the correct flow or velocity under atmospheric pressure. Again... why?
my understanding is that the fellow that posed the Q wanted to fit a diesel turbo into an M20. (perhaps because he already has a diesel turbo cum manifold at hand).
It just WILL NOT WORK! period...
N.B. the right calibration and boost pressure plus the necessary electrical interface to monitor its operation will be impossible to achieve. nice idea actually, though.... (if it wasnt for ECU brain, and smog issues that we have to contend with... i might actually be in favor of the fellow and put my 2 cents worth) ;-)
ADDENDUM: if we wuz talking 75 and older bimmer, i'd take a chance ;-)

I am not using the whole m21 motor. Just the turbo exaust manifold where the the turbo will be mounted. Its has a t3 flange so I changed the turbo out to a new one.The bolts holes wont line up on the head but you can drill one or two out to make fit . I will supply my own piping/intercooler and turbo. My question is to anyone who has done this to their E30 for futher info.
