My brother's build

if i ever end up needing a rebuild, ill get mine bored to 85 and sell it to him so i can get a new one.

do you have a sleeved block? A stock GSR block is only good for 81.5mm. To go higher than that, you have to get the block sleeved. Golden eagle sleeves are good up to 86mm or so if I remember correctly.

lolol stock B20 sleeves will go to 85mm. I have never heard of a B18C1 going past 82mm (and that was with a block guard)
