@Sarra, there is limited information about the EJ203 and what vehicle it came from. It is a true JDM ONLY motor. The only thing I could find is that it came out of a 2004, not sure what model though. But that really didnt matter in the end because it is a single cam non turbo engine which is what I needed and also it is listed on the JDM Racing Motors website as the direct replacement for the EJ253. When you call them they make sure it is in fact the right engine and that it will work for you. If it does not work they will tell you rather than sell you an engine you will not be able to use.
