well......here in brazil we're still running the nova ns series and the rex (same as nova ns series)........

but at the world there was not only one rr12l3........everybody has chosen NS series or similar.....Sirio, RB and Picco......also JP, Max, but they're all nova ns based (except for the suuuuuuuuuuuuuuuuuuuuuuuuuper high exhaust port of the JP sleeve, which I think is the big problem of this engine, all engines with regular exhaust port height are great)...........
