So don't mod your car...?
CBE+Test pipes/high flow cats+intake = 10% to 12% more power over baseline throughout the rev range.
Figure another 3% to 5% with headers and a few more on top of that with pulleys if you are adventurous.
Whether or not it's worth it to you is entirely subjective -- but keep in mind that this "mere" 10% - 12% is greater than the difference in power output between the VQ35 and VQ37.
Thus, I think, not a trivial gain...
If the % increase seems weak for the cost, why don't you check the 1/4 mile times of folks with various mods and base it on that?
Or... if this is about "seat of the pants", see if someone with such and such mods will take you for a drive and see if that helps you decide.
Or... if you just want really big numbers for bragging rights, save up for FI or, I guess, buy a different car...?
