yes it will fit in both .you can use ls rods just have to have a custom piston,there are several ways you can make it work.but the ls and b20 crank are the same.except the b20 has a 84 mm bore. hope this helps you.

Yeah...LS rods and crank are the same as b20b/z..though maybe balanced differently.They are a direct bolt in,using the pistons that came from the block theyre going in.You can use either the b18 or b20 crank in the b16,but you will need custom pistons.It has been done many times before and there's 2 documeneted ways to do it.One is with b16a rods and custom pistons,which gives you a 1.50 rod ratio and 1 is with rebushed LS length rods with custom pistons,and gives you a 1.54 rod ratio.Both have the wrist pin moved up way high.

The old prelude b20 cranks will work in b18 blocks,but it will need to be balanced.You will need custom rods and pistons,or you can just buy the eagle/crower stroker rods and pistons.
