Okay i been having this idea but am holding back on it since i dont have much information yet...

Dream set-up/
VQ 3.5 heads with 350Z ported intake plenum,300hp 350Z cams, 02 pathfinder tb , with the VQ 4.0 bottom end, and a ts ecu.

Will this work???

Yea i know it will be expensive but i tink it might be a little cheaper that an all out stroker kit.

 

buMP.................

 

Sounds sick, but first no tranny will like that (i think) and seccond have fun.....

 

I saw on speed channel on Redline that they stuffed a VQ40 in a 350Z. Maybe you can do some research on that.

 

I would like to see it done, but lots of fabbing will have to be done to make it work. Also you have to find out if the VQ40 block bolt with VQ FWD trannies.

 

i thought he was sayin a FWD 3.5 block, heads and 350z...with a 4.0 bottom end. that would bolt up since he could use the one in his max already

 

how is he going to have a "FWD 3.5 block" and a "4.0 bottom end" in his maxima... or is this going to be a twin engine setup?

 

bottom end meaning the pistons, rods and crank. i was assuming thats what he meant, i really dont know if theyre compatible

 

Ah, I see what you were thinking.

that would be a "rotating assembly" as most people use the terms. when people say bottom end they mean including the block - at least most do. I think that's what he meant - that's how I read it anyways.

 

Isn't the VQ40's block what allows it to have such a large stroke? If that's the case, you wouldn't be able to use the entire rotating assembly and therefore not be able to achieve the 4.0L of displacement.

 

I work at the auction and well today we got a 2006 xterra (totaled) wit the 4.0 VQ.. i took a closer look and it seems like it has both fwd and rwd plugs... what i mean is the vq3.5 from the z has extra bolts wholes on the block, nissan did that so that the blocks for maximas and 350Z are the same...which speeds up production// the 3.5 block and 4.0 blocks have the same plugs.....and so i'm guessing it will work.
The 4.0 block is goin be hard for me to get.. but while i'm looking for that i will be having my heads built I have a 350Z intake plenum,,,but i'm waiting on my check to get it sent to get ported... i went to the junkyard and found a Q45 tb.... which i have at my friends house. All i really need is the 4.0 block and 350Z cams, and ts ecu.
Only way i will know if the tranny bolts on is to get a 4.0 block.

Trying to buy the exterra motor from the auction, wont know till the end of next month.
but first i'm goin to get me a daily driver..... cause my car is goin be sitting for a while

 

Goodluck with that, I cant wait to see how that turns out.

 

Now excepting donations for the project... this idea is patent'd by me so dont dare try to duplicate....if ya do...well i am not responsible for ur car suddenly missing.

 

At the heart of the new Xterra and Frontier is a revamped VQ engine. Formerly a 3.5L V-6, it has now been pushed to 4.0L. These new engines are made at Nissan's Smyrna, Tenn., engine plant. The increased cylinder length/volume was to provide an engine with even more low-end torque, lending itself to SUV/Truck applications. These new VQs also feature continuous valve timing control. The new V-6 produces 265 hp and makes 284 lb.ft, of torque

I'm guessing i will have torque from the 4.0 like a truck and rev-ups and top-end of a 3.5

 

Can someone help me out... i'm trying to find a website that will sell VQ4.0 long blocks and short blocks.... I tink its goin be really hard since that motor has only been produced since early 2005/

 

OH one thing i forgot to say.. the VQ 4.0 is a tall block version of the 3.5 member bigger displacment means longer stroke...thus taller block... I will have to get hood spacers///// Hmmmm that would be nice knowing that i will have a 350Z intake plenum that will already space my hood a good inch or more...lol Umm have to get a scoop!!

Umma be scoopin ;P

 

So you basically ignored what I said and then repeated it later. Now you're talking about having a hideously retarded looking franken Maxima.

Do you really need all that torque? Maximas (especially 4.5 gens) struggle with the torque of the 3.5 as it is with our FWD layout (even with some suspension help, i.e. JClaw's traction bars), why add to the problem? Stick with a 3.5 block, make a custom crossmember to lower it a little, and build it so you can rev the crap out of it. The result is something sure to be fun, look a he11 of it a lot better than what you're proposing, and not have the rediculously unnecessary torque of the 4.0L.

 

250-plus horsepower 3.5-liter DOHC 24-vale V6 with 250-plus lb-ft of torque and dual exhaust Modular cylinder head design, lightweight pistons, continuously variable valve timing, variable induction system... Does the SE-R have better built heads than our maximas???
Any input??
I mean i really want to get this project goin...
but want the best...so i'm be done by like ummm dunno maybe 30

 

Like i have stated earlier..... its a "DREAM SET-UP"
Its is an IDEEEEAAAA...
I wanted other peopls input...
Aren't you curious as what this set-up would do??
I get goosebumps just thinking about it...

 

So you basically ignored what I said and then repeated it later. Now you're talking about having a hideously retarded looking franken Maxima.

No i didnt ingnore what u said... i jus restated it for people that didn't understand the first explanation...

 

Ok, so you restated it. What did you accomplish? My explanation was about as elementary as it gets. If someone didn't understand it, they weren't going to get it the second time with poor English and slang.
Ok, you want other peoples' input. I GAVE YOU MY INPUT. You can choose not to listen to it and waste time and money, but that's you, not me.

 

If you were to put a VQ40 rotating assembly in a VQ35 FWD block then the piston would be well inside the head.

You can use the VQ40 crank, but the rods would have to be shorter. The pistons are the same AFAIK.

 

The 350z block and the maxima block are not the same. Mounting locations are completely different. You can't put a 350z engine in a maxima. Not without LOTS of fab work.

 

Problems:

1. Like tavarish said, how the hell are you going to mount a RWD block in a FWD car?
2. Will you be able to close the damn hood? We know the block is taller and the heads and intake manifold may be larger as well
3. I don't think you'll be able to use the 3.0L timing components. It may work with a 5.5gen ECU though.
4. No one knows if you can bolt up a 5MT or 4AT to this motor.

You'd be better off boring and sleeving a vq35 to get 4.0L. But the price to do that is rather steep. You could use the vq40 crank with custom rods, but that costs megabucks. You're not getting more than 3.5L of displacement into a maxima without shelling out a lot of money for a little bit of displacement and power.

 

Have you guys seen the 350Z block... i'm not using the 350Z mounting holes... there are extra holes on the block to mount and rotate the block to fit the maxima.... Also i'm not using the internals of the 4.0 I will be using the entire 4.0 block......All i need fab is a three layer head gasket to keep the piston from hitting the head.... like i said i'm still reading on this to get an idea if the set-up will work .

 

THERE ARE ONLY ONE SET of mounting holes in the Z block.

If you are using the 4.0 block, then WHY would you have to use custom gaskets to keep the pistons from hittin the head?

 

Since when did the Xterra have a VQ35???

 

It didn't. Made the jump from the VG.


lolz...this guy


Edit: I just reread it and i don't think it's implying that the Xterra was ever powered by the VQ35.

 

You guys honestly never seem a VQ3.5 powered xterra????

I thought u guys had some knowledge on other nissans besides the maxima and 350z//

 

We do, you obviously don't.

The Xterra has never had a VQ35. It's had a VQ40, but not a VQ35. Prior to the VQ40 (and it's current model generation, for that matter), all it had was variations on the VG (VG30E, VG33E, VG33ER, etc.). The only Nissan SUV to get the VQ35 in the States was the Pathfinder (as well as the QX4 and FX35, if you count Infiniti).

 

why brake you head on something so rediculous, just get a supercharger or a turbo on a 3.5 and you'll have all the HP and TQ you want...more then u can handle

 

Or even on the 3.0 for that matter.

 

Keep on dreaming.....

 

The things about dream setups is they are usually unreal because a person needs to understand how engines work to have a dream that could even be fabricated, and they usually don't.

 

Okay..... ummmm i guess umma just built my heads, and hopefully my friend can built my bottom end too. I mean i will do most of the work...jus have him guide me threw the whole thing.

Does anyone know of someone selling headers???

 

Damn... sorry about the Xterra thing. I forgot they has a 3.3 Supercharged motor in there and some other 4 banger as options... forgot they didnt have the VQ3.5 in there.... so again sorry about that.

 

First of all, what do you mean by "building" the heads? Secondly, why?

 

Reading some of these posts makes me wonder how people graduated High School, let alone get into college. It's painful really.

 

I don't know how old you are, but I graduated 8 years ago and it was dumbed down pretty bad then. I was taught where the US is on a world map in my senior year. I'm sure it's worse now. You don't even have to speak English to graduate.

 

Basic port n polish job.. valve's, springs and retainers..etc. To get that extra boost in power that you can get with just basic bolt ons.
