alright... im kind of confused... dont 84mm pistons in a ls make a 2.0 liter... thats a .2 liter gain from 2mm, So how is it with 86 it would only make 2.06
Stock LS bore is 81mm. 84mm bore yields 1973cc displacement. Technically, B20s only displace 1.973L, not an even 2L. B18A/B's displace 1834cc, so going from 81mm to 84mm bore is a 139cc or .139L increase in displacement. 86mm bore yields 2068cc displacement. Going from 81mm to 86mm is 234cc or .234L increase in displacement.

if youre going 86mm, u should get a B20 block and bore that out to 86mm....otherwise, just keep the B18B bored out to its current 84
Stock B20 sleeves bored to 86mm would be dangerously thin. Stock LS bore is 81mm.
