I'm just wondering, since the 07 6spd coupe has a dual throttle body, will the z tube and jwt pop charger be suitable? What about a nismo cold air intake ?

 

you mean the 08 G35 coupe?

the 03-07 intakes do not apply to the models with dual intake... (07 Sedan / 08 Coupe)

 

You mean the 08 G37 Coupe.

 

yeah its gonna take me some time to get used to that one... :-/

 

is dual throttle body and dual intake same thing ?

 

i guess you could have 2 cai on the new coupe... but imo 2 short ram would be more efficient

 

you tell me if you have 2 inlets wouldnt you need to inlet pipes???

 

The 07 sedan has the dual intake setup...the 08 G37 has the same engine, just bored out to make it a 3.7L.

 

Umm, not quite. The 3.5L HR in the Sedan doesn't have the Coupe's VVEL system. Also, you're wrong about the 3.7 being a bored 3.5HR. The bore diameters for both engines are the same at 95.5mm. The 3.7 has a longer stroke (86mm vs. 81.4mm) which leads to the increase in displacement. Big difference between increasing bore and increasing stroke.

 

PWNED!!!

 

Well hell, if you want to get technical...I was simply implying that the engine was very similar to the 07 sedan. I realize that bore and stroke are different ways to make displacement...

Article taken from NICO:

"While the 2007 Sedan received a tuned 3.5L VQ35HR powerplant, the 2008 Coupe will step it up a notch with a all-new VQ37VHR. While this may surprise some, the upgrade to a 3.7L motor had already been in the rumor mill for over a year. A difference between the VQ37VHR and the VQ35HR, besides .2L of displacement, is the addition of Variable Valve Event and Lift (VVEL), now has an 86-mm stroke (up from 81.4 mm) and a compression ratio of 11.0:1 which is four-tenths of a point higher. VVEL is utilized to control valve events and lifts in order to reduce intake and exhaust resistance that leads to energy loss within the engine. Instead of a conventional throttle body butterfly, engine output is controlled by seemlessly varying the valve lift and timing. VVEL will improve fuel efficiency, high torque and allow for cleaner emissions as the existing throttle-body butterflies will only be utilized from an emissions-control aspect. The VQ37VHR will have a 7500rpm redline, symmetrical dual exhaust system and isometric tubular steel exhaust manifolds. Finally, to mate up to the dual intakes on the front facia, the powerplant utilizes a dual throttle body intake system. Horsepower estimates are in the 330-340hp range with 270ft/lb torque. VVEL comes into play here as well. 270ft/lb is only +2 from the VQ35HR varient, yet there is an additional 6% of low-range torque and 4% high-range torque in comparison to the VQ35."

Yes...yes they are different. Two very different ways of of increasing displacement. So much so in fact that two engines of equal cylinder count and layout, and equal displacement, but one oversquare and the other undersquare will behave and perform very differently from one another. Increasing bore diameter will NOT yield the same results as lengthening stroke length. Not by a long shot.

To be fair, I wasn't trying to hurt your feelings by correcting your inaccuracies, just wanted to make sure that everyone in the the thread had the facts. We're all friendly around here. Heck I learn things from you guys every single day.
