Hi guys, I bought an 03 M3 6 speed manual and need a used motor. there are 4 options on the junk yard sites for this car!! 2 are build dates and other 2 are smg vs manual. Now we do alot of motor swaps and usally its something stupid that the interchange system says this. and usually we can just swap it or make it work.. Does anyone have experience with this? as these motors are quite expensive! Thanks in advance! EdScreenshot_20180711-201827.png
