103 kw = 138 hp
I thought that E36 M42's had slightly more power than the E30 M42's, and I am pretty sure they do considering they have improved intake manifolds, narrower valve stems(less airflow resistance and less weight), and lighter, not as strong springs(less hp lost to friction).
But I also got my VIN decoded and it came out at 103 kw or 138 hp and it's an E30 with a 5/1990 build date. I also thought it should have 100 kw or 134hp.
I'm curious what is the reason for the inconsistencies. But either way, it's only 4hp or 3% difference in power.
