"worth it" is all relative for power. The most "worth it" modification in terms of power per dollar is probably forced induction.

I did and some said that it wasn't worth it, that you may get 11-19 at the wheel and some say 20-30 at the wheel.
This is why I posted here :(
Sorry for all the bad that has been written, I was just hoping for a more definite answer.

I don't know what you're thinking but 20-30 whp is 10% gain. THAT IS A LOT!

I didn't say that it would. Just when I googled it, I found soooo many from the low end to the high end and since I am a member of this forum, I thought that someone has done these mods and could tell me

What is whp? Do you mean whp=rwhp? No whp here :icon18: . Go turbo and never look back...

Geesh - I'm glad you're not a burden to society and have a job. I did not say or imply you could not afford it. What I said is if you have the funds go get TT or SC if not save up for it rather than spend money on 11 to 30 whp and later on go to FI like some of the guys did.

You're looking for a definite answer, you won't get it, you'll get a range depending on the mods. As I learned by reading posts and searching around like a lot of members already suggested, mods do not add up incrementally. Good luck with you.

Z1 has a Stillen Gen Intake that they said was Dyno proven on 370Z to give 17.5 increase at the wheel ! LOL, see I did do a search :)

This isn't a video game. Gains are not going to be the same across all cars. Gains, even with the same mod, vary based on manufacturing tolerances.

By the way, something about the way you type makes you seem like a very small child. Can't tell if it's because of the questions your asking or the way you're asking them but I think it rubs people the wrong way. All of the questions have been answered before. If you didn't get your answer the first time then please RE-READ because the answers regarding intakes, exaust, hfcs, etc. have been discussed adnaseum.

More horsepower comes from pixie dust sprinkled on your engine by a GOOD fairy.
You'll know you have more horsepower when little children clasp hands, form a circle around you Z, and dance in a circle singing Ring Around The Rosie! :happydance:
