I looked at that spot where the VIN is meant to be and nothing was there but just off to the left about 8 inches are a bunch of letters and numbers stamped in to the firewall (not on a plate) with the first three characters being EF9. Well there you go. The engine swap was done in japan so it must be a JDM motor, and the exhaust has 2 oxy sensors therefore apparently making it a b16a1. Also some interesting facts on the ef9 wouldn't go astray, I don't know heaps about honda's, but from what I understand the ef9's pretty good. Thanks everyone.
