    honestly you could but it would require some modding. AND im not entirely sure if it could physically fit due to sizing but...

    1. the m20 radiator doesnt have a fil cap; it uses a reservoir. to get around this, you could cut the upper hose and clamp in a remote water neck filler.






    2. do you want to use the stock transmission cooler? the location may differ from the m10 rad and m20 rad as with the fittings. When i used a manual rad in my auto m10, i just routed the transmission lines to a regular oil cooler from a truck...

    3. how are you going to mount it? like i said earlier, it may not fit physically, i dont know the dimensions of the e21/e30 but if it does, it shouldnt be to hard. from looking at the inlet/outlet of the radiator, you probably just need to extend the hoses a little bit


    this is how i would go about putting an m20 radiator in an m10 e30
    ?

          Typically the locations for inlet and outlet on M10 radiators are Top Left and Bottom Right.

          There are exceptions.
