View Full Version : Difference between S13 and S14 SR20 oil pump

Would anyone know what the difference is? Oil pumps are year specific and I would like to know the difference.

Reason why I am asking is because I have a brand new oil pump for my S14 SR, but I think I might need a new block, and I can hardly find any S14 blocks when S13 blocks are abundant. Would it be the difference in the head that makes the s14 oil pump differ from the S13 one or is it something else?

There was a guy in Oki th used an S14 Bottom end and an S13 Head on his setup

Aww great... So that would mean I'd need an S13 oil pump to match a S13 block with a S14 head. Thanks a lot.
