maximum overbore gs1100

[amxsteve]

I am looking at some new pistons for my 82 1100 motor and was wondering if is possible to safely bore the stock cylinders to 79mm.This will be a low compression turbo motor

To my knowledge 75mm is the max bore.

Steve, you can go 75mm on a stock 1100 block, 77mm on a stock 1150 block, or with a re-sleeve you can go 80mm on a race only setup on a stock block. Anything over 3mm overbore on a stock I HIGHLY recommend a "big block".
