Hey Guys I opened up an engine today. Head code is 53J 6R. I'm assuming it is a complete JDM import. My friend pulled it from a G20 at the local junkyard. The engine has a Nissan valvecover so I'm thinking an engine swap was performed in the past.
This engine has 9.5:1 compression pistons, and standard valves(53J,64Y), high port head. No Ribs on the side of the head. I'm not sure what color scheme the valve cover was originally as it has been sanded down to bare aluminum.
