What issues surround just swapping long blocks but retaining the M42 intake/exhaust/OBDI system, etc.? This is in context of using an available M44 1.9L long block in lieu of rebuilding the existing M42 1.8 in a '91 318iC.

Just because I found a 1.9 M44 in good shape that I can swap cheaper than rebuilding the M42
well I'm assuming the mounts are probably the same and so is the tranny/rear. I'd imagine that the computer wouldn't be too much of a problem thing. just strip down the m44 engine to the block and use all retaining parts from the m42 engine that fit and hope it works. this is basically what I did w/my 6 cylinder swap.
