Z3 S54 radiator is the upgrade. Should fit, E36 M3 guys run them all the time. Edit - that would just be for a swapped car though, M44 radiator has the expansion tank integrated, you'd have to figure out the correct lines for the Z3 rad. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM Last edited by spidertri; 09-19-2014 at 09:02 PM. |
