Does anybody have an Upper Intake Manifold, the collector, and TB that they could either sell to me or loan me? It will need to come out of a 02-03 Maxima 3.5L.
I need to make my CAD drawings based off these manifolds. Thanks!

I might need a spare TB from the 3.5 also. OR, if someone can give me pics of what the backside of the TB looks like compared to the upper collector tube, that would help. I just need to base my drawings off of either the TB or the elbow tube. I need to design which would be better for airflow and cosmetic appeal once it's installed.
I will NOT skimp on my design and testing of this kit. The first run of these will be perfect just like the first run of my VE spacers.

Ok stupid question...
For the guys who have modified their Intake Manifolds, would we see extra gains with the spacers too (if the spacers gain any extra power at all)? I have yet to modify my IM (eventhough I have the write-up) and I am waiting for the spacers to be finish, so I can get a good tune with my SAFC II with the TS ECU.
Or should I just go ahead and modify the manifold and get dyno-tuned.

It's not really the lengthened intake plenum spacer that gives the power. That helps. But it's the cooler intake manifold temps that really makes a nice difference. The intake manifold temps can be decreased by as much as 60 degrees. Average temp decreases are usually 40 degrees for other cars.

But this is going to be an AWESOME kit! Two Lower IM spacers, Upper IM spacer, Upper IM collector spacer, and a Throttle Body spacer. It's not set in stone right now, but that's where it's going right now.
I don't want to talk too much b/c I want to have this kit developed and tested before stating facts. Right now, it's all 'here say' since I'm in the beginning of the design process.
But this kit WILL get made!

But I can't say for sure. If for any reason they don't, then I will design spacers for the 6th gen also.

man i am interested in seeing the temperature change. i just changed my plugs last night and after driving 10 minutes and letting my car sit for 2 hours at 50 degrees my IM was Still pretty damn hot. and yes the gaskets are flimsy metal. any idea when these will be available and if you are doing a before and after dyno???? not sure if that was mentioned already

So right now, we are on track!
Yes, I will be doing before and after temperature and dyno testing.

Thanks
These phenolic intake spacers have a more noticable gain in the summer months than they do in colder weather. The hotter the temps get, the more gain you will see!
The guys on this forum with the VE30DE motor are always complaining about heat soak. It's only noticable when the motor gets up above 210 degrees in the summer months. But by keeping the upper intake manifold cool, the heat soak is almost completely eliminated!

Also, since the Altima has an EGR system, I will conduct seperate testing for the 02-03 Maxima. I believe the spacers will be the same, but other testing will be needed to accommodate the change in emissions. Once I make the spacers for the 3.5L Maxima, I will test fit them on the Altima and make sure they fit perfectly.

If you're in need of any down payments, or anything.. I'm more then willing to donate some cash (so long as I can get the amount I have to pay discounted from the amount I donate
) I'm VERY interested in this modification.. and I know JUST how hot the intake manifold can get after a hard drive. The cooler is stays, the better it is. Add on nitrous and oh man! It's going to rip!GENE

No down payments will be needed. I will just go ahead and get these made for you guys as fast as possible and release them after a full day of testing.

to unbolt anything in the bay. I am only about an hour east of Sanford 5 minutes off highway 264. I will be more than happy to install these for you for an extra cost. PM or email me if you want pricing for labor.
maxima0001, the VQ30DEK has a composite plastic type intake manifold which already stays pretty cool. I don't see any huge gains that can be had by using these phenolic spacers. We might only be talking a couple horsepower on that motor. But on the VQ35DE, I see a huge potential.

Ahh ok....Now I see...
As I always say, the less work the better.....
Ty for your response nonetheless, it was very helpful!

I finished reading this thread, after FINALLY coming back to this board and I don't see any rough estimates on how high the upper IM and runners will be raised. Too much and it won't clear most FSTBs. Just wanted to throw that out there, has come up in past discussions about this.
I really hope this works out. Nextgear just dropped off the face of the earth after some interest.
