Early e30 rad or e36 m52 rad for swap

[E30randy]

I have the e36 rad that came with the m52 and then my old e30 rad from 86 325e. Which one should I use? I have piping for both too

I went with the e36 radiator. Either will work. Really I replaced a stock m42 radiator with a mishimoto.

I'm using the stock e30 325i rad for my m50 swap - drove it through nevada in august, never ticked over the halfway mark!
That said i'm not sure if the 325e rad is the same

[M3PO]

Yeah, I have an 84 325e and I think the rads are different. I went with an E36 rad and welded in the later model E30 mounts.
