Hi, I've got a JDM K20A that has just lunched itself (con-rod thru block and bent valves). Its fitted to a low-volume kit car. It had a JRSC fitted a couple of weeks before it blew (ran fine for nearly a year before that). I've taken it back to the shop that fitted the JRSC to complain. They say I must have mis-shifted to blow the engine. I didn't. Is it possible to plug into the ECU (hondata - sorry don't know exact model), to check the max revs that the engine had spun to? I've read loads of forums, but haven't managed to get a definitive answer (like directly from a Honda tech).
