Searched and did not find an answer to your question, maybe you have since you posted? Haven't found anyone else on thread with same code other than you.

I also have a JDM transplant with codes 53J 1L, valve cover has black channel, color is alternately described as champagne or gold, the donor car it came from had an auto trans. Described to me as 10:1 CR motor by Dave Coleman before I bought it, but other than that, don't know much about it. He replaced the original USDM SR20DE with >125k miles with this JDM motor and then set up to pass CA emissions pre-OBDII.

I have a lot of pics of the engine before I went into the car, plus pics installed. DC set it up with the full EGR for CA emissions compliance. I can't see other codes unless they're hidden by the coil, next time I have a reason to I can take it off.
