I have seen a fair number of M52, S52US conversion. I hear it is pretty much an easy upgrade (for a seasoned professional), with only some special modifications. I haven't ever heard of an S52 upgrades, but that engine will NOT be cheap. Figure at least 15k for the engine and tranny...plus any install costs. I would peg that upgrade at at least 25k.
A more cost effective alternative is to find an S50US from a wrecked 95 M3 and install that and at that time or later you can easily add a turbo or SC to get more than 321hp.
I have seen used- low milage 321HP euro S52's including wiring for around 4K USD and another $1500 or so for the 6 speed. It's not uncommon for people to overpay certain shops (they'll remain nameless) that think they are the only ones who can get euro-only engine's/parts. I'm very tempted to do this conversion but I like the idea of keeping the original S14 as the powerplant the way BMW Motorsport intended.
shove that S52 in there and wipe every s14 powered M3 clean. with the right suspension mods you can get the car to handle like a dream again.
BTW I would like to know where you can get that motor for 4K? that would be sweet in my wagon.
