260-270 WHP NA? Heres is the missing link(new 2004 oem max part)
Above is a pic of the 2004 maxima bay, it's hard to see whats under the cover but heres what nissan has listed.
They have the motor specs as follows:
Engine features include electronic throttle, silent timing chain, microfinished camshaft and crankshaft surfaces, molybdenum coated pistons, resin intake collector ,digital knock control system, cross flow coolant pattern and higher capacity muffler.
As you can see the intake manifold is indeed new, it no longer has the very poorly designed variable intake manifold. It now incorparates a resin intake collector . This may sound cheesy to some but it is(well should be) a big improvement over the 2002-2003 variable intake manifold. The 350Z and G35 show a 30 WHP gain using there very well designed intake manifold(thats where there extra power comes from).
So what does all this mean? It means I have a new project comming up in may
With the addition of this manifold, OBX headers, Apexi S-AFC and iridium spark plugs I hope to see around 270 WHP NA and 250 WTQ. Don't beleive me? You will see.
Should be awesome!!

Sounds great. While you're at can you find a way to swap out the the 4 speed auto tranny for the the new 5 speed auto. I know, I know, you have a manual.
Good luck on the new intake project.

A new ECU and new tranny should do the trick for you. I'm not trying it
I have been looking around on www.nissannews.com and I found the following quote on there.
Maxima’s legendary performance continues in 2004 with the continued use of the award-winning VQ 3.5-liter engine. The VQ engine series has been recognized as one of the "Ten Best Engines" by Ward’s Auto World magazine for eight consecutive years. The DOHC 24-valve V6 has been refined to produce 260-plus horsepower and 250-plus lb-ft torque. The increase in power and torque was created, in part, by modifying the intake duct and exhaust muffler, thus improving the intake/exhaust flow ratio. An equal-length tuned exhaust with a high capacity muffler adds power and gives Maxima a quiet, yet strong, sound – hinting at its performance capabilities.

........hmm i wonder whats in the way of that battery being mounted the 2k2 way..mebby a big air collector over in that corner...

AgisAbatzoglou, sorry but what does the 2004's maxima weight have to do with this?

heh, throw in that new silent timing chain in there while youre at it.. How is that a new feature? You cant get Nissan to acknowledge that the 02's are noisy, but they call that a feature in the 04's
there's nothing u wont try w/ your 2k2....I bet you'll be the first turbocharged 2k2

the g35 has the microfinished camshaft and crankshaft surfaces and molybdenum coated pistons, so does the 350z. i don't think the 2k2-2k3 has them... err maybe they do. i hope your project works. i will do the same. hehe.. sorry for copying you. =) while your doin that, might as well put the timing chain on to eh? hehe. btw, does that make it quieter?

270whp? NO way...... 255-260whp maybe.... Ethan, I would really have to take a look at the intake manifold but dont think that is going to eqivalate to 10whp. That is too much, that is damn near Ypipe territory.

Keep in mind the 2004 max is on a altima platform, and if you look at a altima the battery is moved in the same way.
Does that now make the Maxima the Altima's fat young brother

The Z dynoes at 235-240 WHP stock. The extra power comes mostly from the intake manifold. So a 10 HP gain fom a good flowing intake is a understatement, try about 30.

I think 30 is a big overstatement...No way

Well, this speaks for it's self.
And
And for all you nay sayers, explain to me why the 350Z has 40 more WHP stock over the max, come on let's here it? lol. Please dont say cause there motor is better because it's identical, and don't say it's the "exhaust". The 350Z gains 20 WHP from a Y-pipe and 11 from a nismo exhaust. So whats left I ask, think it;s the headers? No thats right headers dont do jack you all say? So I ask why exatly does the Z breath so much better then the max I ask? Simple, think about it...
And if the max new manifold does not pan out to be good I am going to fininsh my 350Z manifold conversion, infact I might get right to it now.

I believe the numbers that emax says can be put down with the 2k4 intake manifold... but I was wondering if the 350z has slightly different internals that contribute to the extra 30-40 whp ALONG WITH the different manifold

Like I said, Im not putting you hopes down. I think the Z also gets it power from different compression ratios and other small nick nacks. I think exhaust differences are like 10-15whp tops from 2k2 max and Z.
I'd still consider porting the intake manifold and headers if you want to hit up high #s.

I know your not putting me down Dixit, you just don't agree with what I'm saying and that's jsut fine.
Ok and I will again point out the fact that the Z puts down much more power then the max. Heres my question again, where is the extra 40 WHP comming from? That's RWHP mind you, typicly a FWD drive train is more efficient.
Compare apples to appleas here, what does a MEVI have to do with this? Differnt applications can and will yeild drasticly different results.
Do what exactly? You lost me here.
Why would porting a poorly designed intake manifold make it "the best flowing intake ever"? I fail to see the logic here. Intake designes vary greatly and simply polishing a poorly designed intake will yeild little to no results. By no means does polishing a bad intake make a good intake. If this logic held true why do people buy a MEVI? Why do many, MANY aftermarket companys sell better flowing intake manifolds?
This notion is apsurd and I am shocked your even saying this, you really have a lot of research to do.
The Z and the max share a 10:3:1 compression ration, AKA the same. And there are no nick nack differences, this has been proven many times now. The are identical.
Like I said before the Z has shown nice HP gains from after market exhaust systems, just like the max. So the extra power the Z makes does not reside here.
You over rate porting and polishing way to much. You can port and polish the hell out of any crappy piece and it's not going to make it a good piece.
[B]
Emax you missing the point, im not putting you down, just saying dont set the standards too high.
I dont think an intake manifold alone is going to give you 30whp-40whp. What you misunderstood is that I dont think the intake can be that bad from the 2k2 to a 2k4.
The biggest gainer on intakes in the range of 30-40whp came from the MEVI.
But in our case the 2k2 and 2k4 and Z all do that already.
So even if we ported the max intake manifold to be smooth as hell and make it the best flowing intake ever, I cant see getting anymore than 10whp.
The best porting job would have to be better than the Z intake manifold or the 2k4 manifold anyday.
Like I said, Im not putting you hopes down. I think the Z also gets it power from different compression ratios and other small nick nacks.
I think exhaust differences are like 10-15whp tops from 2k2 max and Z.
I'd still consider porting the intake manifold and headers if you want to hit up high #s.

FWIW - when I had the VIAS problem on my 2k and the intake was not changing over at 5k, I dyno'd the car and compared it to the earlier stock dyno I had done.
The result was a loss of about 35-40 HP TO THE GROUND at redline simply from a failure of the intake to switch over.
So, clearly the intake collector can account for the difference.
The only question I have is whether changes were made to the ECU maps as a result of the change in collector/air flow to allow the car to better utilize the change.
