    I am going to look at a civic with an alleged JDM B18C Type R swap. How do I know if it is a gsr engine with a red JDM valve cover or the real deal? Does the GSR have duel valve springs like the type r? If it doesn't I figured I could pull the valve cover and see if there were duel springs or not. If anyone knows of any block or head stamps the would distinguish the two I would greatly apreciate it. I intend to purchase this car very soon, please help!! Thanks.

    Engine code

    GSR B18C1
    R B18c5

    (JDM type R's will NOT have a numerical designator, or so I hear)

    head codes

    GSR = P72
    ITR/B16 = PR3


    intake manifolds

    if by chance he is using a Skunk2 manifold on a GSR (copy of the JDM ITR manifold) the manifild will have a CARB number on it if its a real JDM ITR there will not be a CARB number on the IM

    both JDM ITRs and GSRs will say B18C

    both JDM ITRs and GSRs came with red valve covers

    Thanks for the info.

    So do both the GSR and ITR engines have duel springs? On which side intake, exhaust or both?

    Thank you.
