Im building a B18A1 right now and I got some b16 pistons and rods. Im wanting to know if the b16 rods will be able to fit on the b18 crank. Is the bearing bore the same size? When I go to get new bearings for the rods do I get the number off the rod like normal and the crank to get the bearing size?

Thanks for your help. :thumbup:

 

B16 rods are not the correct length. They're too long.

 

B16a blocks have a shorter deck height so using the rods and pistons will make the piston sit to far down in the cyl which will not compress the air.

B16b uses the same block as the B18 however the longer stroke of the B18 would push the pistons out of the top of the block and hit the head.

Your answer is yes they will fit the crank...no you can't use them.

 

Very good expination. :thumbup: Thanks

Well now I need to press out all the dam pins and swap the rods. :down:
