I bought these out of wrecks, so I can't personally say I've heard them run, but the seller promised they were good. Not really sure how much these are going for these days, so if you don't like my prices feel free to make an offer.
Alloy M52B28 from a manual 1997 Z3 158k, complete except for oil pan. $800
Alloy M54B30 from auto 2004 330xi 110k, complete except for exhaust manifolds. The thermostat housing is cracked from the wreck. Comes with DME, key, EWS unit, throttle. $1200
ZF320 from the 97 Z3. $350
I am unable to deliver or ship at this time, they have to be picked up from my house, zipcode 18951
