I am looking to rebuild and sleeve my D16Z6. I've been really happy with it but I am interested in getting the JDM pistons that develop the higher compression ratios. Does anyone know what the hp output was on these engines? It is difficult to get a straight answer. Plus do any of the racing piston makers carry of the JDM piston sizes? I am thinking of supercharging soon. Would there be a disadvantage to going with a supercharger and the higher compression pistons?
