Noticed my engine block stamped 13B--thought that was prior model... (during one of many oil checks). BTW, was in shop during first 500 miles for check engine light. problem was oil injector SW program. Reprogrammed and replaced injector just to be sure. No problems since then, over 3000 miles. Just curious if others have 13B stamped on their engine, too.

yes the renesis is a 13b and they are all stamped as such. Officially it is the 13B-MSPE (multi side port engine) although i have seen it written without the "E" also
