I have a line on new Mahle European 10:1 Compression pistons, will know more by tomorrow or latest Friday I hope? I would like to do a group buy for those of you doing 3.5 clean to dirty swap or are planning one. These are the correct piano top style pistons and will not work in a later 1988 and up motors as most of you may know already...
They fit all 3.5 blocks 85-87 535i, 82-87 633 csi, 1985-1986 735 i and more m30 blocks if your willing to bore your 3.2 blocks possibly check with your machinist.
92mm std bore, or 92.25 or 92.50 oversize for 3430cc give or take few cc's if your going oversize?
Compression height 39.85mm
top ring 1.5mm
middle 2.0mm
oil 3.5mm
There are no NOS rings anymore, however think those can be found rather readily check with Total seal see what they have.
