    M51, m21 swap

    is it possible? How hard would it be?

    Sounds like a domestic guy.

    into what?

    an e30 I assume?

    m21 wouldn't be that bad, as e30 324d/td's came with them stock

    m51 might be a little harder, but I'm sure its possable

          Why??

          M21 is... well... slow as hell. Things like turbo upgrade are not worth the money spent.
          M51 - better, but by any means not economy car.

          If you want a diesel in E30 try M45 - probably lots of work, but you get an economy diesel with some power to go.
