My Ride: comes with blow
I could be wrong but if I remember correctly, the M50 intake manifold (I assume this is what youre referring to) doesn't fit properly to an M52TU engine (the head is different from the M52 engine, which was found in the E36 range).
It was a popular upgrade for E36 M52 engines, yes, but the gain in hp did come at the expense of low end grunt. Without modification, I think it doesn't even fit on an E46 M52TU engine.

Can't comment on the cams, sorry.

Well at least we are actually getting somewhere. That sure is a bummer because that would be an easy 10-15whp gain. Thank you for the info though.
