S50 Cams into NVM50?

[LuckyHenriksen]

Point taken, still tempting me :) I will see what I can come up with over this winter

So swapping the M54 rotating assembly into the M50 block will just produce a 3.0 M50 right? Which would essentially be the same as an S50 short block?

Not really.

Pistons are be nicer ; lighter as smaller bore.

sides are coated. The e46 pistons got fancy coating on the skirts.

Stroke is much longer. Bore is smaller.

S50b30 USA is old in comparison; new stuff = advancement, nicer lighter and smarter.

It's thanksgiving !! Need to get in the holiday spirit!

Smaller bore seems to allow the hg to hold more boost as the bigger bores have less space for sealing.

This having been said my fav engine (s54) is Oem 87mm bore and has almost no thickness between
cylinders. :p

S52 is 86.4 bore
S50 is I don't know bore
M50 and m54 are 84mm
Bore.

S50 exhaust cam goes on the exhaust side.
Both nV intake and s50 exhaust are the same. 240* 10.xmm
So people either run dual intake cams or swap the exhaust for s50 exhaust.
