hi, looking to put m104 3.2 in w201 2.0 sportline chassis,or would a 2.6 chassis be better for the job? can anyone help,any info would be great

A 2.6 chassis is already modified to accept the longer I6 motor. All accounts I have heard say that the m104 (be it 3.2, 3.6, etc) will bolt up using existing mounts. The wiring will be challenging regardless of what era w201 you use, though the latest MY car you can find, the better in terms of ancillaries and other electronic systems being compatible
