Will a 350z throttle body fit the 3.5 ac?

[Mr.Coupe]

Hey guys. I would like to know some information. Well I have an 08 3.5 and I would like to know if a 350Z throttle Body would fit and be fully functional with our/my engine? Hope you guys can help. Thanks in advance (TIA).

Thanks dude.

This is an old pictures. I have done SO SO much to the car since then.

ok-ok "I have no clue"

What would a 350z throttle body do?

What year 350z??

I would just like to know if it would work for our A/C's. And any year 350Z or even the 370Z. don't matter to me.

Thats a great question, and if it will work, a definately needed find. Ill do some research on that asap.

What? the turbo isn't fast enough for you Ricky?

I would imagine it would work as long as the bolt holes line up. But what's the use of that? A throttle body controls the amount of air that flows into the motor. Replacing it, IMHO, will do nothing. However, with that said, putting a phenolic spacer def. would affect the way the air comes into the motor. It would act more like a tunnel ram...sorta...

Oh dude the Turbo is more then fast enough. I'm pretty sure that the throttle body would bolt up to our VQ. The only part I'm not sure about is if the harness will plug and work correctly. I was sitting at my office and think what could be done to the engine or the altima. Please explain further about the phenolic spacer dude. I'm interested to know.

Thanks for your help and ideas.

Find any good info that would be useful?

There's no mystery with the phenolic spacer. It's just what it is a spacer. Basically you're putting more material thus increasing the space the air has to travel. The phenolic is just a material that resist expansion like metal would do.

BTW, How long have you had the turbo and what do you think about the drive-ability. Did you notice a reduction in MPG? And is the reduction due from you hammering it to get on the turbo or because of the bigger fuel injectors, normal driving is compromised.... Sorry for the thread jack

thanks for the info of the phenolic spacer. I've had my turbo for about more than a month and the driveability of it is great. I actually didn't get a reduction of MPG. I actually got an increase of MPG.

Okay... call me stupid... but the ECU doesn't know about it, so it is metering the same amount of fuel-to-air. Traveling a longer distance by the size of a relatively small spacer (a couple of inches at most?) is not necessarily going to be more efficient, but possibly less so. The spacer will add outer wall turbulence to the charge, since it can't meet the intake pipe or throttle body perfectly, so flow could actually be worse, and how will you now fit a performance intake since there will now be not enough room for it? (Intakes are a tight fit already!) Like I said... I may be stupid! But I don't get it.

This may be a bit off topic but could we get the dual intake setup like the 350z has?

First we have to find out if the throttle body from a 350Z would fit and be fully functional. Then there could be modifications to do something similar.

Im going to try and take one of my mans z and get my mechanic to see if it bolts up correctly. At least he will take a close look at it. Ill PM you and let you know exactly what happens as soon as possible.

Thanks dude. And please also check to see it the wire harness hooks up correctly and turn the car ON and give it some gas, drive around and test the F'ER out to make sure there won't be any check engine lights.

Hey Ferg,

From my prev G Sedan, I know that intake spacers/plenums were popular on VQ engines a few years ago for a couple of reasons. The first was that the airflow to the front two cyclinders was compromised a bit due to a frame member on the 350 that required the engine to be a little shorter in height. The same plenum was used for the Gs, so companies (like Motordyne) started producing intake plenums with better flow to these cylinders with decent gains. There was also a spacer that fit between the top and bottom half of the stock plenum to achieve the same effect.

The thermal spacers were used, and made out of a plastic material, to help keep the air/fuel cooler and therfore more dense and more power. These sat below the plenum. They also increased low end torque a bit because a longer intake runner holds more air/fuel which has more inertia to keep it moving forward when the intake valve closes and the cyclinder isn't really sucking. The net effect is that pressure builds in the runner a bit and you get more air/fuel in the cylinder when the intake value does open. Once RPMs increase, you're exactly right, the added friction of the longer runner becomes a liability and you loose some top end power.

I don't think either of these situations apply on an Altima because our intake plenum is different and already made of a non-heat conducting material. Motordyne certainly doesn't make anything for the Altima, and they would be the obvious choice to produce it since they already have the parts.

[Ferguson]

Appreciate the info on that! The constraints you mention make sense but I didn't see how it applied to our coupes. A little history goes a long way. Thanks!

Are there any new updates? (took me 2 days to find this post again. I hate when they move the thread)

Sorry LBC I did not mean that in a bad way. I know you guys do great work. but are there any updates on this subject?

[FGFCacoupe]

I love this car, and just like anything else that I love, I strive to bring its full potential out everyday, rather it be my car or another human being.

Thanks dude. And please also check to see it the wire harness hooks up correctly and turn the car ON and give it some gas, drive around and test the F'ER out to make sure there won't be any check engine lights.

No problem man, im on it, and if it can bolt up, ill do all of those things and do a write up so that you can see the entire process, step for step. So this way if my mechani or I have t make any minor adjustments, you will know exactly what to do if you proceed to bolt one up. So hopefully it works

Just to keep you guys posted, im just waiting for my man with the z to get all of his parts in. He is going with an entirely knew setup, and he is waiting for all of the parts to come in so that he can do the installs all at once. He is thinking about installing all of the parts and selling the car so that he can get a 370z and if he does, ill buy the throttle body spacer off him to see what I can do.

[brakthru]

hey guys,

Any updates on the z throttle body spacer working on the 4th gene altimas?

[Dexion]

I don't know about the spacer but I doubt any Intake Manifold mods would produce any worthwhile results, unlike the 3rd gen motor. We already have one of the best flowing IM designs in the industry. (4th gen VQ)

Yeah,

I contacted those f'ers at motordyne about our altima's and the alti community having spacers/ manifolds produced.

They never responded.....

[dangeris]

So FGFCacoupe,...did your buddy get all the parts and did you make it work on the coupe?
