i just saw some pics of a pathfinder intake manifold 01-04 and i know they have a vq35de but it looks as if the upper IM actually will bolt up to a vq30de. The holes are oval like the 3.0

so im wondering...has anyone tried this out before?

i thought i read a thread on this before also...tried searching for it and couldnt find it.

so will it bolt up?

 

I highly doubt it would bolt up and I highly doubt you would like the performance change it makes.

 

ive heard that if you get the upper and lower it will bolt to your 3.0, someone said they were trying it...

 

zack342 blolted it up to a vq30de LIM and it fits. He sold it to larrio.

 

yes we awaiting for Larrio to get it on and everything working and Dyno results

 

did either of them drive the max with it on? any comments from either of them?

 

By my measurements everything does fit under the hood. Just need some time to test fit on a spare VQ30de I have around and figure out how to work around the DE-K stuff inside my car.

I'll try to get some teaser shots near x-mas

 

You will have TONS and TONS of low end power. Your midrange will be okay at best. Top end will also be amazing. That is what I see from lookin at the runner lengths.

 

sounds like it would be a dream to drive!!

im actually thinking of making this my winter project...

 

subscribed......

 

How? is it a VI?

 

yes it is...

long runner is like 1.5x longer than stock 4th gen and short is like .5 of the stock!

 

Ya it is a TRUE vi as well. Not like MEVI or 00vi(upsidedown mevi)

 

Imagine a 4th gen USIM with an extra half of the manifold length added on for the long runner and a switch off into runners so short that it practically goes from the TB to cylinder in about 6-8 inches

 

Exactly

How heavy are the manifolds and is there an EGR hole?

 

any photos ?

 

heres some...
in engine bay








as you can see from the pics...the long runner comes from the throttle body - forward - then winds back under and down into the lower IM.

the short runner comes from the throttle...into the large compartment seen in the 4th pic then straight into the lower intake manifold of the 3rd pic.

 

No EGR hole from what i've seen on mine.

The manifold is fairly heavy in comparison to the stock DE-K composite one. I'll weigh it later on tonight

 

How? If you have poor midrange, you have to choose between pounding the crap out of your internals with all that low-end torque and screaming around above 5k RPM all day.

Unless you're running at the track... in which case you'll have no traction off the line, and your times will be crap because your redline isn't high enough for the top end to make up for the lack of midrange.

 

so wait, has anyone done this swap before? how much would the cost be compared to a 00VI? ohhhhh, im soo excited if this works.....

 

I would use this knowledge to run a a full pathy VQ35 with a 00 VI. Stephen Max found out a while back that it uses the same sensors/timing chain setup as a VQ30, but with early VTC's. The point would be to run the pathy VQ35 w/ 00 VI on a regular VQ30 ECU and wiring harness, and add on stuff (RPM switch?) to control the VTC's.

So VTC's without the wiring of a 02+ ECU, you get to keep simple cable throttle (no e-gas and electronic pedal), but you do get VTCs. Although they vary less than 350z/maxima VTCs.

 

If Nissan just made a front-wheel-drive 3.5 Pathy.......

 

sounds good...but why use the 00VI? the 00VI is for an engine that is .5 liters smaller...so i dont think it flows better than the pathyVI or the other 3.5 IM's.

 

Until dynos have been done with the VI open, closed, and dialed in we will just have to wait. I think the short runner length only may work well at the track, similar to the SSIM. On the street the long runners would be good in the city like the VQ30DE USIM.

 

The runners are the same shape, so it wouldnt need any boring or customization to fit and flow well.

 

Well if the 00 VI is great on boosted engine, it'll do fine on a NA 3.5.

 

You'd be surprised.

 

The people that went from a 00VI to a 2k2 IM noted a power gain.

 

Yes - extremely poorly matched to FWD VQ35 heads and lower IM. No one has tried VQ35 pathy heads and lower IM with 00 VI.

Seriously - the whole pathy VQ35 (okay, perhaps with FWD VQ35 shortblock) running on a VQ30 ECU but with VTC's on top of that - and a 00 VI - would be a great setup, really. I hope someone tries it. Then we will know FOR SURE how well the 00 VI works on an NA VQ35 setup since the heads and lower IM actually have oval ports that match up perfect to a 00VI.

 

wait...ppl noticed an increase in power with a 3.0 w/2k2 IM or 3.5 w/00VI IM?

this is getting really interesting...

 

We're not talking about 3.0s.

What happened was that some people with 3.5 swaps were using the 00VI even though the ports didn't quite line up. Then they switched to the 2k2 IM and got more power (duh).

 

BTW, is anyone concerned that Pathy heads might not be as good for high RPMs (>6k)? Has anyone looked at them vs. other 3.5 heads and compared?

 

It did and if anyone is interested I have Lower VQ30DE manifold with injectors for sale.(shameless plug)

 

Cost $30 too ship its darned heavy

 

 

 

The pathfinder Heads

 

I hate to bring up a really old thread but what happened with this? I was looking for info about a thread where someone mentioned chopping up a pathy manifold for a 3.0 and ran into this.

 

Good point, and search for posts by 98seblackmax and you will find the other thread you are thinking off, don't know if he gave up after all the timing cover issues but you should bump that thread as well.

So with the '02vi properly portmatched set-up that I did I think we can now assume that even though the '02vi gives huge gains and 1k rpms early than an '00vi, for a motor that is setup to rev out, the '00vi is still the king. BUT, I'm still anxiously awaiting the 2 manifold people have been sleeping on - the de-t & pathy, I have alot of faith in the pathy.

 

So how could you mod one of these for a 3.5 ??
