What's the difference between an e30 m tech and m3?
There we two versions of the E30 M Tech in the UK - the 1 and 2. They both had the 6 Cylinder 2.5L M20 engine (I believe the only difference between them is a slight change in the M Tech factory body kit). The E30 M3 also had a couple of different versions but they all had the S14 engine which was a 4 Cylinder so that's the main difference. (They put a highly tuned 4 Cylinder into the M3 to preserve the weight distribution - this is why the 318is is referred to as the 'Baby M3' even though it was not the most powerful E30, it just had a solid 4 Cylinder).
TL,DR: M Tech cars had a straight six and the M3 had a 4 Cylinder.
