Which engine should I go for?

Haha, stonking is strong , and reliable :)

Yes, I know that we got those motors here... my s50b30 Euro is lying at my mech's place

why aren't you going to use a s50b32?

Cause I prefer the square motor, the 3.2lt has a nasty habit of throwing a rod when revved.

and at a later stage I want to use forged internals, and some wikkid camshafts... which would mean the peak power is going to shift till about 8000rpm, and rev limit will be at 9200rpm ... I dont feel comfortable revving such a long stroke (3.2) that high even if it has forged internals.

Plus I personally think that the 3.2 isn't all it's cracked up to be... the power was very overrated by BMW IMHO.
