I think it's pretty relevant. I mean, a tune can change the personality of an engine. Just wondering if the Nismo gets any of its hp from a chip as well as its different components.

Also, I thought there was a fairly decent replica wing out there, or close to it.

Nismo wheels are fairly easy to find. Brand new, they'll run over 3 grand. If you're patient and lucky, you can find them used on here for less than that.

But I agree, by and large. If you want the Nismo, shell out for it.

Wow, really didnt expect too see another one of these threads pop up from a member whos been registered since this car's been available, but since I am trying to help before the lock...here goes nothing...(please search)

better member than myself, he provided the links for you!

Thanks for all these links, honestly, I wasn't trying to branch out my thread to be about body kit, and other stuff. I've read those threads and I'm only curious about the tuning aspect of it and to see if both cars were to have the same mods, it would pretty much means both cars are now starting from having 332 hp and + whatever performance gain the aftermarket provides.

For example:
Nismo 370z:
350hp delete OEM Nismo Exhaust (-18 hp) = 332 hp and then (+18 hp for FI CBE) = 350 hp

Sport 370z:
332hp delete OEM Exhaust and then (+18hp for FI CBE) = 350 hp

Or will the Nismo 370z still have bit more HP because of the tuning?

Not trying to beat a dead horse but, I just showed 5 links of about 40 which returned from a quick search. I have seen this topic discussed before but I think I've steered you in the right direction. Hope you find what you're looking for.

No, both cars HP will vary since mods have been added and not tuned. Having a car slightly tuned before mods i.e. Nismo doesn't mean it carries over. I believe that's what you asking.

Either way the body kit will hold the Nismo back in a straight line race, it's like .1 in 1/4. On a course the Nismo vs Sport is marginal with the same driver, unless said course has high speed turns/braking areas. Then the Nismo will shy forward.

Plus if you retune each car with all the same mods, they will be tuned the same way and this new tune will negate the old Nismo tune.

It is believed the 18 HP increase is from the S-Tune exhaust and a mild tune.

I've read most of the 5 links you posted and majority of them pretty much sums up the same thing, but it doesn't neccessary answer my question. In general, they all just say, if you want to mod it, go with a base/sport as oppose to a Nismo because of blah blah blah amt of money you're gonna spend or how the Nismo body kit is a waste of $$$ b/c it's ricey or whatever. - I'm not interested in that as I am not trying to figure out which car to buy. I already own a Z.

My question is "theoretical". I am not trying to go about find out whether it's worth it to buy either a Nismo or Sports with my limited budget and see which one fits me better.

I'm purely wondering if one to get a Sports 370z (let's just say) did all the Nismo suspension upgrade, body kit, etc you name it, but still running on stock ECU and original engine. So the only thing that's identical to the Factory Nismo. Should they have the same HP if they both has the same exhaust system (whether if it's Nismo exhaust or any other aftermarket one)?

One thing we know for sure is that Nissan claimed: Nismo got their extra 18 hp from Exhaust and a tuning. But is the exhaust alone +18hp? or is it from a little bit of both?

To your question in post #23...answer is YES, seeing you can get the Nismo tune from the dealer.

There was a thread of a member who got "hooked up" from the dealer with the tune.

Ok since you don't want to click specZ's links, let me summarize:
-Both cars have identical VQ37VHR engines.
-The nismo has unique bells and whistles including bigger wheels, a stiffer suspension, a really nice looking body kit + wing, and a nicer exhaust.

This isn't like say...a mustang or a corvette where different trims have entirely different engines and are built differently.

All Z34s are identical deep down. You can replicate/exceed the nismo's performance in a base with a few bolt-ons. Those same bolt-ons will provide the same gains in a nismo (assuming you don't replace nismo-specific parts) and the Z34 is fun because it lends itself easily to modding.

The nismo's extra power comes from the exhaust and a different tune. Not that big a deal.

It's a bit of both.

Ok you can close thread now.

Thanks, that was helpful.

If you throw in a tune like uprev plus bolt-ons then they become the same as far as HP goes.

It really is not relevant. The reason being, if you mod both the Nismo OR the Stock Z, you'd still want to tune it after to get the gains from the mods...

Thus the Nismo tune get's thrown out the window.

Buy on looks, not performance.
