I know many are going to say just use a 00-01 VI or a MEVI. However I don't really care for either I really want to adapt this intake manifold not only for the coolness factor but the gains, I guess gains range from about 12hp N/A and about 30-40hp with F/I.

Kinetix

If hood Clearance is the only issue I really don't care as that can be easily taken care of.

Thanks Guys!

If that's what you want to do, go ahead and lead the way.

 

Yes, please try. BTW, your link doesn't work, nor does copying and pasting the URL.

 

Hood clearance is only an issue with the STOCK 350z/G35 intake manifold. Kinetix and Crawford's plenums are smaller and more compact, and according to both of them, fit under the hood of 02+ Altimas, so it should fit in a VQ35-powered 4th gen.

it will bolt on with the 350z lower and actually bolt to the 3.0 heads but it will not line up to the heads right .

thatsb the IM i have in mind for my car or maybe the other one the other companys gonna produce that will be pure NA IM.

 

interesting

You would also have to have your intake pointing toward the pass headlight and youll have to either get a 3.5 TB or pathy TB and make a adapter plate for it.

 

Are you talking about the piece for the throttle body pointing towards the passanger headlight? If so thats okay because my chage pipe goes that way anyways.

Hmm...Couldn't I just make an adpater plate for our Stock Throttle body?

Also you said it would bolt to the heads but would not line up correctly anyway to remedy this?

Thanks Guys, I appreciate the help.

maybe you could widen the 3.0 to 3.5 head specs. I wouldnt try.

And with the TB if your gonna use the smaller 3.0 TB i wouldnt even bother with the intak manifold because why choke it with a TB but pay good money for it.

 

Damn you guys are right on the button with this one I already know...

 

Why not..?

 

because some of that head area is cast thin and for that trouble with that nice manifold i would just use 3.5 heads which i have

 

Krismax,

I understand what you are saying and I am curious if I can retain the VQ30 Bottom End and adapt the VQ35 Head.....ahhh....what to do....

 

There have been some before and after dynos presented in my350z.com which show no gains after installing this IM. Looks pretty, though.

 

Expensive shiny piece of crap then ... It looks like ours w/o the dual chamber stuff.

 

Why can't somebody just design a good IM for us? It's not hard, just produce a FWD version of the 350z IM that fits under our hoods. They'd sell like crazy. Altimas, 5th and 6th gen maximas and 4.5 gens would be all over it. They'd make tons of dough.

 

^^ I'd get one.

 

Work in progress

Even if the Kinetix showed no gain on the 350z, it might show a gain on the 02+ Maxima/Alt etc.. But what do I know .. exactly nothing.

 

A stock 350z intake manifold has a muuuuuch better powerband that our IM. It's basically like comparing a 95-99 3.0 manifold to the 00-01 VI. Night and day.

 

The 350Z intake manifold is an engineering marvel. I don't see how ANY aftermarket company could significantly improve on it. 105% volumetric efficiency at 5600 RPM will be EXTREMELY tough to beat.

 

They don't need to beat it, they need to match its power and make it suitable for FWD applications. The gains would be significant. SR20DEN's Secret Sauce Intake manifold already gives big gains over the original IM, and I doubt his modded IM is better than the stock 350z IM.

 

Very true. I agree. I was just saying that in response to aftermarket companies trying to improve on it, that's all.

With all this said, i think SR20's manifold should go into regular production...

 

once a pure NA IM comes out for FWD or RWD its gonna be mine but a prob with useing 350z IM is you need the 350z lower also that holds the injectors because its not the same as the 3.5 FWD lowers.

 

I wouldn't mind buying a 350z lower intake manifold.

 

I think there $220 new without rails or injectors but thell swap over from maxima

 

And just to let everyone know you will need a powerbulge in your hood a couple inches and it will be offset on the hood

 

This is referring to the 4th gen or 5.5g? Or both? Or do you know if it's the same for the 5.5g?

 

this is from pics ive seen of one tried on a 5.5 gen max . i would say that for 4th gen its not known 100% but i would bet its the same ,TB neck is the main prob.

 

Yes, but the kinetix/Crawford manifold is considerably smaller than the original z IM.

 

Smaller footprint, but what about height?

 

I am too chicken to put it in regular production and it's more difficult for me to get them done now since I don't work at an auto shop anymore.

However, I have some ideas to make it even better to the point that everyone would want one over anything else. If I can find a way to pull it off I'll open the flood gates.

 

Whenever you're ready, we got the cash in hand, tons of us.

 

Well the one I have now is easy to copy (for those who have the right equipment) and that is what scares me. However the one I want to sell would be too complicated for anyone else to consider, and It would make the car go down the track even faster.

 

How much were you thinking of selling them (roughly)? If your price is fair AND the thing is complex no one will want to go through the trouble of copying them.

The aftermarket 350z IM's cost like 1g's. It would be funny if the Z/G guys ended up being jaleous of your FWD manifold

 

Most Z guys just have too much money and spend it on the latest product, little of them actual do tinkering/engineering on their own to improve a product. That's what makes the small Maxima community that does this unique..IMO.


I'd like to see what the Gen II SSIM is all about too. .

 

Hmmm...I wonder how a Vq35 powered 4th gen with a secret sauce GenII would perform? and some tomei cams w/cattman headers and 7500 rev limiter

 

Who makes the 272 cams .

And don't forget the rod bolts.

Only time will tell.

But for now, we can just work with what we have.

 

Give me one and ill test it on the dyno with my 00 vi ,ill prob dyno in 3 weeks. And ill respect all secrets .

 

i'd be willing to wait for an sr20 IM
i guess i'll just sit back and hope =)
