Can it be done?
Snaped some pics and the lower looks the same. The design is similar to mevi but I wonder if there would gains.

 

 

 

yeah but wouldnt the throttle body be in the fire wall?

 

That's nothing that a sawzall couldn't fix. It's not similar to the mevi or 00vi though. It's a true dual runner intake. Super long ones for low end torque and super short ones for top end power.

 

The concept is interesting, but it seems like an awful lot of work for very little to possibly no gains over the MEVI. I would LOVE to be proven wrong though, so please, by all means try it since it appears you have one in your possession. Looks like the torque could potentially be rediculous, but given that the length of the "short" runners would still be really long (nearly as long if not as long as our USIM), I have to wonder how it would flow on the top end.

 

It looks to me that the short runners are only 3-4in long when the butterfly opens and it just dumps straight down into the LIM. That thing would definetely hang off the front of the motor. Interesing though.

 

I see ITB's.

That's one hell of a difference in runner length...

 

Make TB side come out in the front, then it's naturally induced air path right ahead of it. Kinda like RSX's intake manifolds. Block the EGR, Make IACV adapter plate with extended hose, get a longer throttle cable, extend a few more hoses, it's done. Willl have major problems during oil change, though. Not a practical idea.

 

It is a VQ35 Pathfinder BTW. The Pathfinder never had a VQ30. That is a very nice looking IM as far as how it shoud perform.

 

I know....I have a spare DEK in my garage I think the throttle body would actually face the radiator.

 

Good point.

Plus, would it even fit under the hood if you did it that way?

 

ill come pick it up and install it and tell you

 

It would face the front... I think you would need to flip the lower IM 180° though.

 

you seem to be missing something or havent put it together yet . the pathy isnt like the MEVI or 00 vi it is a TRUE VI.

this has 12 runners in the pic its decieving on the way its setup

 

^ It looks like all the pieces are there...

This is the way it looks on the engine:



Also it looks like you would have to do something about the hood too.

 

Looks like the VQ30 oil cap should clear fine too.

 

Interesting idea Zack. I think it would be a good challenge to get it to fit correctly, even if the manifold collector lines up with the lower intake manifold section.

You could always try and test fit it on that spare VQ30DEK you have sitting around in your spare time. You would not know about the hood shutting correctly though.

 

Would you even have to flip the lower 4th gen IM 180*?



I wonder who will be the first one to try this and dyno it vs the 00vi?

Although, it could take a camaro style hood scoop/cowl to make it fit under the hood with the TB right there next to the radiator.

 

Tons of low end. NO mid range. Tons of topend.

 

LOL no traction, 15.4 @ 104mph.

 

boost can cure that issue

 

^^^ Wtf??

.....

 

i think he means cure?

I would love to see a dyno of this IM. Zack, get your *** up here and we can install it. The we can drive 2 miles and dyno the darn thing.

 

I wonder how hard it would be to chop it and make the loooong runners more midrange friendly.
It looks like the top portion of the longer runners goes up gradually to make a better turn into the lower portion, it dips down, and gradually comes back up to where the short runners meet?
Maybe just chop the longer runners off totally and fab up some shorter runners with aluminum pipe? Sourcing the bends might be hard though.
Might even be able to make it clear a cut support stock hood.

 

i guess i need to write it all out for you.....

boost can cure the no mid range this might supposedly cause

 

I'm not dumb. I understand what you said but failed to understand WHY you said it. Boost can cure the lack of mid-range? Boost can cure ANYTHING if you want to look at it that way, but that isn't the point of this thread.

 

well you comment upon what i said had nothing to do with this thread but that sisnt stop you from typing away. why i said it is non of you concern since you don't actually make the thread about this. if zack or whom ever started the thread wants to know why i said it then i would love to explain why i said it

 

What liqidvenom is suggesting is true in that, if you could find a turbo that operates at peak efficiency in the range in which that IM is weakest, turbocharging could make up for the IM's inefficiency at least partly.


What nismology is saying is that no matter what you do, you can't change the fact that that IM is weakest in the midrange. Sure, you can try to fix that with boost, but why? You'll just end up with a turbo and an IM that never work together 100% since they are never in their most efficient ranges at the same time. For all the time, money, and effort you spend installing this IM and then trying to find just the right turbo, you would be able to get a lot more benefit out of your car by just going with a decent all-round IM that fits directly and then designing and building your turbo kit accordingly.

 

thanks....glad someone can put things together

 

ha ha, thanks for the clarity. btw, i did a search but i didnt find anything. but. how come no one ever did the pathfinder 3.5 swap? i think i saw somewhere the compression ratio was 10:1 as opposed to 10.4:1. anyway, i think it would make sense, since it uses throttle cable.

 

Ummm...i can too. I just don't understand why boost was mentioned to begin with. If you have to "fix" a modification with boost, is it worth doing? Like i said, if you want to look at it that way boost can fix anything. Need extra low end, get a small-ish turbo. Need better mid-range, get a medium sized turbo. Need crazy screaming top-end power, get a larger turbo. Need to lower your 1/4 mile times, boost it.

Saying boost can "fix" things goes without saying and is besides the point of this thread 100%. Completely irrelevant. Boost can "fix" a stock maxima for that matter...

 

RWD block...

 

the only thing irrelevant is everything you have posted to try and take away from what i've posted. he came with an idea to install a new manifold to his car. i have never seen it will do on a maxima no have i see what kind of gains it will make with different types of forced induction. if thats something you don't care about then stfu and move on and stay on topic. i like to see the envelope get pushed and to me seeing what this does n/a, sc, turbo, nitrous is important to me and hopefully to other people if this seems like a worth while thing to do. people build lots of cars with parts that n/a don't make much sense but once you add force induction that mod(s) suddely comes to life. this may be such a mod for our cars and maybe if you stop being a child and be quiet then this thread can advance some.

 

i think its actually not (at least in the 4wd versions). friend of mine has one and i could swear its transverse, but i could be wrong. ppl could use the engines from vehicles such as murano as the engine is transversely mounted

 

Like i said, i don't think your post was germane to the discussion. I'll leave it at that. Good day.

 

no ur wrong....the pathfinder and murano use different 4wd and awd systems

 

liqidvenom, I think you two are speaking different languages. All he's saying is that boost won't fix that IM's deficiencies, per se. That's true. Now, correct me if I'm wrong, but it sounds like what you meant to say is that boost will make up for the deficiencies. That's true too, and it's not incompatible with what he's saying.

You're also saying that with FI, this manifold could give benefits that outweigh its disadvantages, so you'd like to see what it can do. What nismology is saying is that it probably won't be worth doing. That's really just an exchange of ideas, since as you both know the argument is purely academic at this point.

See? No need to get panties twisted, guys...

 

ok...so are you saying neither would work? transverse is transverse, i dont see why they would change the block design and i KNOW that the murano engine is transverse
