7th gen swap into 4th gen
Can anyone point me in the direction of information regarding the VQ35DE found in the '09+ Maxima and what would be involved in transplanting this into a 4th gen Maxima?
I've read all the VQ35 swap threads and know what's involved in that, I'm just specifically looking for the differences between doing a 5th/6th gen VQ35 and a 7th gen VQ35 swap.

I would do a little research and find the threads that delve into the differences between the motors, DL the FSM from the cars in question, and began looking into the differences there too.
Also, the L32 uses a very similar ECU/engine set-up to the 7th gen, if not the same, that's a place to look into as well.
Plenty of info on this forum on the L32 (07+Altima).
With all of the ECU/standalone options available, it's very doable. Only concerns would be your time and dollar commitment.
It might be more beneficial/cost effective to look into some cams, maybe some mild headwork, and the new 07+ IM vs staging an all out operation A34 swap.
IIRC, there might be someone on here with all of your answers.

1.) How deep are your pockets?
2.) Do you want the FULL A35 swap (to include ECU)
3.) Do you want a SA tuning system, or do you want to convert to something close to a full A35 swap (more like Z33 ECU, in the works by some members) and take advantage of the software out there (OSIRUS/UpRev V-Manage both come to mind).
The reason it seems as if we are semi shady on the subject (at least me anyways) is because from the looks of your short/vague posts, it seems as if you haven't even scratched the surface on what needs to be done for even a Z33/A34 ECU covnersion. And all that info has been posted.
Also, to clear up a few things, mechanically, the A33B/A34 swap are identical (sans some minor EGR stuff), BUT, electronically, the A33B vs A34 are quite a bit different, and I imagine the A35 to be even more difficult than the A34.
But with all of the tuning devices out there today (V-manage, et. al) there are options, but, research is something you need to consider, and a LOT of it.
I'd keep a laptop next to my bed with the A35_EC section very close to my bed. If you're not dreaming of wiring diagrams and such, you're not doing the research you need to.

If you wanna use static cam timing and 4th gen fuel maps, all the info is there. And if you cant figure that part out, you really need to step back and research alot more. Or take it to someone and have them do it for you.
If you wanna do a full ECU swap, (which is highly recomended by me for this motor) get the FSM for your car and for the A35 and read till your eyes bleed as nmex already pointed out.

the 7th gen Maxima VQ looks totally different,
which I agree with Kevlo , I worked on one and I notice the motor is completely different than the previous VQs.
the Altima VQ35DE with the plastic intake is one thing,
the 7th gen Maxima VQ35HR is way too differnt , doubt the 6spd will bolt up without making a plate,
and since its a CVT tranny, not sure if that tranny seperates apart /Bellhousing.

Dumb question, but why not older VQ35 bottom end w/ a 7th gen top end??? I'm sure the gaskets could use some redrilling/shaving but would the heads go on the DE bottom end?
Which timing cover would one go about on this venture? I dont have a copy of the 7th gen fsm on hand.....
Just an idea...

I belive the HR deck is higher if im not mistaken ( someone chime in )
even the VQ40 has a double oil pan , so much variables.. wouldnt even be worth it IMO to go thru that.
but if I know something, that someone on this board will be willing to spend their time on it as long as someone gets a hold of a 7th gen motor.

The 09 max has vtc on the intake and exhaust, the 07+ altima only has it on the intake. The block used in the 7th gen is different, and i believe the bellhousing is a differnet pattern. you could use a 7th gen engine with a L32 6-speed though. I'd def go with either the stock ecu or a stand alone, you'd have to set up the fuel maps and timing curves properly with the stand alone to get even close to the 290hp that the stock ecu istuned for.

What is the difference between the L32 6spds and A33/A34 6spds (in terms of bellhousings, not internals)
Because I'd love to bolt up a 7th gen motor to a 6spd and standalone.....
It seems positive, because AFAIK the L32 Altima and A35 Max have the same CVTs... Soooo..... I like where this is going...

SurraTT here,
say hello to the 2009 Maxima engine.
Bascally FWD HR, minus few things
Expect a thread soon on full info on this motor, loosing the myths, and telling the facts, and how to get this in a 5.5 gen with fully working exhaust timing.

^ im surprised there isent more info on this motor, considering this IS maxima org ud think we would have more info on a 2009 motor.
But hey ill take care of that. hhahah
anyone got a spare ac compressor i can borrow for a lil while?

The info is widespread and a lot of it is out there. Most if not all of which you probably already know about.
If you need any info as in for me to gather what has been posted (even though it's been about 90% from me and 2 other members) let me know so we can consolidate it and give you what you need in your pioneering effort.
This is going to be fairly awesome.

i think ive seen most of the info on this motor, i dont know of anyone putting into a 5.5 gen. only ive seen is into 4th gen with 4th gen timing, so not worth doing the 09 at that point.

Mmm, question... other than having an HR motor in the 5.5, shouldn't thre still be more "stock" whp vs the regular vq35de even if you use stock ECU?, still 3.5 timing.... when my motor went I was seriouly giving this a thought,I know however that nobody here would know how to do it, now another question I have is, if and when we figure out how to get this into a 5.5, would anybody consider making the brackets an mounts as a kit for anybody who wants to do this in the future cause I sure don't mind having my car sit out a while for his project also.... mated on a 6mt... WIN!

I think the reason why there isn't an abundant amount of info is because the motor is too newish, pretty hard to total out a $40k car (not impossible though), the motors have to be going for $1,500-$2,500 at least and a lot guys on here will blow the $500 on a 2002 3.5 before they blow that kind of cash on that motor. So really no one has the cash to blow to dig into this motor fully yet and a lack of bolt-on mods is also key, unless you want to go completely custom on stuff.
But I'm glad its you Surratt that will be doing this...dare I say? Father of the VQ35HRFWDish. LOL

Ill agree that I probebly would spend the $500 on a 02-08 3.5 before a grand plus on the 7th gen, now whenever suratt is done with this I'm sure their will be dyno numbers which should tell if this is also worth getting on the performance aspect... any idea or estimate on when this swap should be done?

How do you plan on making the exhaust timing work?
I was under the impression that those cam motors are controlled by a PWM signal.
I was talking to my professor at my school about this and he mentioned using something like an Arduino board to control it.
It's basically a little programmable circuit board with a couple of PWM outputs. It can be programmed to output anything you want and it is programmed in a language very similar to C++.
I already have the skeleton code to control a PWM based on RPM as we used this to control the speed of a wind turbine for one of my projects.
It also runs off of 12 volts.
This would allow for a simple RPM vs. PWM map.
I'm not sure if that is how the exhaust cam timing is controlled, but if so, this seems feasible.
You can also do 3d arrays, so you can make a map for RPM vs TPS vs PWM as well.
