I was wondering if anyone might know the thickness of the cylinder walls on a b20 and a b18b?

 

81mm=b18b, b20=84mm

 

I actually worded it wrong, the thickness between the cyclinders is what I am looking for. How much can I bore befor the cyclinder walls become too thin?

 

82mm max on b18b. B20 is already pretty thin. 84.5 maximum to be safe on a b20. I've seen a couple 85mm bores around here but mainly its a risk.

 

I think b20 walls are 6mm thick, my gsr block walls are 7mm thick, but you shouldn't bore more than 82mm on a gsr/itr block

Yeah, 82mm is the max on stock sleeves.
