questions about b20's
--------------------------------------------------------------------------------
I have a question bout these 2 cranks, I was wondering if they are the same, if not which is better, i need to know because i just bought a b20b bare block and im trying to put it back together, and piston rods are the b18a rods the same as the stock b20, NEED INFO ON THIS ASAP

Re: questions about b20's (hondahead87120)
you cant use the pistons cause the b18 is an 81mm bore while the b20 is a 84mm bore. sroke is the same on both which is 89mm

you can use an LS crank in a b20.....you can use the RODS of an LS in a b20, you can not use the pistons in the b20
b20=84mm
b18a/8=81mm
you could use the 81 mm pistons if you resleeved the b20 and went to a smaller bore but that would be stOOpid.
b20b/z=b18a/b cranks an rods
