There also plenty of WAAY better exhausts and suspension mods out there than can be had then what the NISMO is equipped with...they are on the same playing field...like it or not... you paid a ton of extra cash for for sup par exhaust, tune, suspension tweaks. Most people who REALLy want to turn the Z into an all out track car dont go for the Nismo, they get a base and build...

You can justify it anyway you want but it's the same no apples to oranges. It's like saying the iPad mini is totally different from the iPad. Same device, one just has a larger screen, same device and everything. You I believe have force induction, so you had to or should have changed out everything except for suspension that you paid extra for...just stating facts...
