bore on b16 n b18
 

is there a difference in da bore of a b16 n a b18 cause they r selling me some pistons for a b18 n i want 2 put them into my b16 please help thanx

same bore... different stroke..... ur gonna need smaller rods i believe....

they both have a stock bore of 81mm.

Like the guys said this will work. Both 81mm bore. But it will also lower the compression ratio. So the real question is WHY? I assume you are posting in all motor, because you want to do an all motor engine. This would drop your compression down to 8.5:1 or 9:1
And that my friend would suck balls for all motor!

yea dont u want like 10.5 and up:1?

well thanx for da advise, so if i get some b16a pistons dat would b better right
