I'm looking for oversized pistons for my M90 motor in E24 of 1980. Original BMW/Mahle are out of stock since few years. I would be happy to order custom casted pistons. I've heard something good about hypereuthectic Alu alloys. I've already checked at:
JE Pistons, UEM (Keith Black), CP Carrillo, VAC Performance, Kanter, Egge, Summit Racing - they don't offer for BMW.
Does anyone has an idea where to ask for in U.S. or Europe?

It looks like forged pistons should not be a big problem at JE Pistons or Wiseco for instance. Maybe you could advise others?

Maybe somebody heard something about original new pistons for sale? Relevant numbers for +0,2 mm oversize is BMW OEM 11 25 1 278 112, Mahle 082 23 01. Piston outer dia 93,56 mm.
+0,4 pistons are also interesting for me.

How about starting with those that build similar engines: Metric Mechanic, Ireland Engineering, Korman, Coupe King...?
