Here is further proof of this claim:
Both my NX and SE-R have VEs with N1 cams. The SE-R is still untuned with the cam gears at 0,0 (waiting for my Realtime ECU
) but has the ASP SuperFreak header, a ported head and N1 intake manifold, and a 3" exhaust. The NX has had some tuning, the gears are at +5,-5 and it has the ASP Budget header with a 2.5" exhaust. The rest of the motor is stock. The NX has a fatter upper midrange (5200-6500), but obviously runs out of breath compared to the SE-R beyond that point.
