are there any differences between the Sedan / 350Z / G35 coupe? Can 350Z headers work on a G35? can the motors be swapped in place of one another?

Lastly , are there any Z33 / G35 owners in here that have performend header mods / turbo mods and want to get rid of their stock header equipment?

Thanks

Matt

 

The only difference between the three is ECU programing.

The manifolds will interchange, or so i've ben told.<--no reason to doubt that

To the best of my knowledge yes they are the same. As a rule of thumb the VQ series will be indentical between the Nissan and Infiniti brands. You may have a slight difference between the blocks that are horizontially as opposed to the longitudinally(sp?) mounted ones. So the swap, without acc., should be identical.


Keep in mind i do not have first hand experience with a swap of this kind. Only a lot of knowledge of people that do tool around with these kinds of cars every day. Hope that helps somewhat.

Are you planning on a VQ swap into the 240?

 

I'm really after the reasonign for the different horsepower levels.

 

Well, the G35 was given a few less hp so it wouldn't show up the 350z. Just to give the turtle every chance it could for making a good entrance into the U.S. market they gave it seven extra hp "on paper." Infact, they may have the same ecu programs and just the specs are claimed as different. There is no way of knowing for sure unless you crack and read both ecu's.

As far as the sedan goes that was more along the lines of the natural competion with the maxima. They have always been closely intertwined with features and options. The only real differences between the cars until now was the hood and standard leather interior with the Infiniti. With the arrival of the new generations of cars the companies wanted to seperate the brands a little bit with the styling. However, the same idea of giving the disadvantaged Nissan a little more in the engine, as with the 350z and the g35, holds true here as well. The quoted specs are a difference of 5hp but as i said earlier there is no true way of knowing unless you were to read the ecu's.

Nissan has claimed the difference between the vq in the 350z and the max is a different ecu program, a larger intake and more free flowing exhaust. There are some problems with that claim though. The larger intake on the 350/g35 doesn't neccessarely mean better airflow. The maxima's variable intake is extremely efficient and i'll show you how that translates in a moment. They may be right about the ecu's though. It seems that the 350 and g35 ecu's will reset themselves adjusting for mods. This is only hearsay so i don't know how much is truth or just peoples frustration at not being able to tune the car as they easily as they thought it would be. On the exhuast side i don't know how much i believe that one system is much better than the other. The engineers have been known to have done a hell of a job at designing a very efficient and free flowing exhaust since the very first vq series engine. I think the designs are just as efficient at expelling spent gases on all models the vq sits in. You have to realize that there are different engine placements for different models and take those designs for their intended use. So in actuality exhaust may have very little to do with the differences in power.

Now the interesting part. The real world dyno's of the 04 maxima has shed some light on some very interesting facts. It appears that the 3.5vq in the maxima is putting down numbers that coinside with a car that has a bhp of 280hp. This tidbit started showing itself once the new maxima owners started getting their cars baselined on the dyno's. Now i'm not certain of the g35 sedan becasue i have not seen anything for them but i would imagine some similar results. So all things considered the only probable difference would be in the tune of the ECU's. I'm sure there may be other factors for the difference in numbers, but that would be very small.



Hope that helps in some way???

 

What are you looking to get for them ?


Also, Does anybody know if you can switch a 2002 maxima 3.5 crank angle sensor with a 2000 maxima crank angle sensor ??

 

Oh yes, the swap is on...is it not?


Not sure about the sensor but if the part numbers are the same then you are golden. It would think the sensor itself would be the same. Maxima.org is down right now, but if you want to ask some specific questions about your project then try www.vqpower.com That should be a good place to start.

 

BobD, did you dyno your car after you put headers on it? Are you going to dyno it after you put the DC headers on to see the differences ???
