I have placed the same question with my source (BMW dealer). I think that I will get an answer on Monday.
BTW: You could go for a used block (without pistons). These don't suffer from metal-fatigue and therefore are a very good basis for going to first oversize (93,60mm).
An S38B38 block will work as well. I know someone who used pistons from the S14B25 (E30 M3 sport evo) in an S38B36, which requires boring to 95,00mm. Since the S38B38 has a bore of 94,60mm that will work.
I may have a VIN of a legally imported 3.8 in my archive.
Bob, my friend put a call into bmw ag on friday to find out what the status is on 3.6L blocks. Current there are none, but the part is not listed as 'no longer available' which makes him think something is in the pipeline. I know if a friendly 3.8 owner who may loan you a vin if you need to go that route (which wouldn't be bad, from a performance standpoint).
Regarding the 3.8, bmw na also requires ownership and importation documents to bring in euro parts. The car must have been legally imported to the US and federalized. So we'd need more than just a vin.
Since bmw was asking for cores back on these various block/piston and short engine sets, he's thinking maybe they'll be offering remanufactured engines.
First, I want to thank you for calling your "dealer BMW" sources, since with my "dinan /peter pan/stevans creek 'source," and all the calls to Germany all of those "sources," made, I am very pleased to announce, for all the world of BMW guys like us, that BMW has agreed to start making "reman' blocks, for 3.6L engines E34 M5s, complete with piston set, two year warranty, and unlimited miles.
My "order" was sent to Germany on November 12, and I may have been the first order in the US for a new one under this I hope new BMW ag "programme", and I am told from my Dinan source, that my block will be shipped from Germany on November 17. (customs pass through could take weeks).
No matter. I had already had my "heads" finished, and they are beautiful, a machine shop next to and recommended by Dinan.
None of this would have happened without your telephone calls. What is your preference in vino? Santa wants to send you a thanks.
Rest of story, here, goes, I also ordered a "reman' tranny, at $5600, from BMW, ag, and again, two year warranty, unlimited miles.
I am now waiting for Dinan to put it all back together and after "break-in," can enjoy what BMW intended for what MMiller at "bimmer" calls the best that BMW has ever done.
Again thank you so very much.
(Note I still may order a back up block just in case BMW ag "backs out.")
Ps thanks to all of you out there sending me your recommendations. I looked at them all, but decided to stay with the "mother ship."
Hopefully,you checked prices on sites such as bmwpartstore and Tischer before ordering your transmission.Though BMW list is 5600. or so,I've seen much lower on these sites and having done business with both,I can vouch for their service.I purchased a factory rebuilt Getrag a few years back from a local dealer for a reasonably discounted price but since,I've had alot of experience obtaining parts from the mentioned websites for a complete rebuild of my "93 3.8.Good luck!
