My question is this. **What are the similarities and differences between the M3's S14 engine and the 318is M42 engine(apart from displacment)?** They look very much alike from under the vavle cover!! I was thinking that with the high cost assosiated with the E30 M3 S14 engine could one simply swap the S14 for a M42. With the cost difference, one could easily develop a nice intercooled turbo setup giving the M42 in the same power (or more) than the S14. This would retain the weight ballance of the 4 cylinder E30 M3. One could drive the hell out of it and if it breaks, simply find another M42 engine.

Correct me if I'm wrong but didn't the M42 put out like 190 HP with the DA supercharger?
