JRC702 obviously doesn't know what an M30 is...

Having rebuilt an old 3L M30, I know that a mildly ported head and
stainless steel headers will give you an easy 30 hp and some torque.
It's quite possible that an intake manifold will add another 20 or so.
A total of 50hp (easily doable with those options IMO) is much more
than you will ever get from an M50 (and I have an M50B25 in my '91 E34
so I know what I'm talking about, here.)
