Also if the Block says D15B then it's a JDM D15B because D15b7 blocks have D15b7 stamped on them.

But the head is what gets me... never seen that before!

- Mon Feb 15, 2010 2:50 am #175393 there are stampings on the head
look right above your exhaust manifold
on the upper left hand side should be stamped something not sure for this head
if you take a good pic of the front of your motor we should be able to tell you :thumb: :thumb:
on second thought you will have to remove the heat shield first
