Title: 1600 piston hole size
Post by: 70's Looker on May 16, 2013, 06:26:28 PM

Hey if anyone has a stock 1600 case sitting around, could someone measure the inside hole size? I just got some 88s and want to know if they are slip ins or machine ins

Thanks everyone!

There are three sizes for 88mm cylinder base.
Slip in are 90mm. (Not recommended)
Machine in are 91.5mm and 94.4mm
94.4mm are best.

thanks camron!

 i had one of them checked out the other day, and it check out to 92.3mm, they are old ks ones so i guess i got the right ones!

  i couldnt match up the part number on the box to anything on kolbenschmidt's website so i had to ask the question!

The sizes I gave were for Cima / Mahle 88s. I don't know what the KS sizes are.
