I have only seen one NSX that was supposed to have over 300HP naturally aspirated, 9000RPM Danny. Has anyone built there car up to 300-325 with good results? If so, what did you use? I am thinking higher compression, maybe 11.0-1 or even 11.5-1, engine management(advanced timing), cams, titanium retainers, port matching everything, extrude hone the intake, adjustable fuel pressure regulator(more fuel), balance and blueprint the engine and proper tuning should get me there. Anybody out there who has tried this?
