FW: Custom Pistons - relocation of gudgeon or wrist pin & chice of manufacturers
My apologies if this is appearing a 2nd time. Thought I'd sent it before,
but didn't see it on the list.
Has anyone on the list had any experience with custom pistons (say @ 82mm in
bore) and relocation of the piston wrist pin?
Any tips, hints or things to consider or specify in having a set of pistons
made? High silicon content; low?
Manufacturer experiences - JE vs. Wiseco vs. ?? vs. Mahle or Kolbenschmidt
(don't know if you can get custom sizes and/or other mods in the Mahle or
Any ideas how far "up" (i.e. increase in stroke length) a pin might be moved
in an Audi 3B / AAN piston? Is 5.5mm or 6mm doable?
JE wants a complete piston w/ rod to look at. I rather not disassemble the
brand new engine that's in the garage to pull out a piston if I can avoid
it, and the other candidate for supplying a piston is still in the car
moving it around town.
