I have a 92 GS-R but I recently blew the motor up.
Im still desiding on what motor to swap in but I came across a really good deal from a friend that needs money.
Hes got a Built GS-R It recently droped a valve and scored number one cyl. wall. He was bored 82mm my question is what is the max/safest bore on stock GS-R sleeves.
If the block is no good where can I get factory sleeves, or could I use the sleeves from my B17 and bore those out to 82mm.

Thanks in Adance for any help

 

Well 82mm is as far as you want to go on a unsleeved block.You could get the bad bore sleeved with a stock replacement sleeve but you would be better off just finding a better block.Oem sleeves are not removable,they are cast into the blocks.
