I understand that and it does have plenty of everything if it's done right and it's true that there are a few now pushing high HP reliably without even sleeving the block.

I just want the VHR just because it's still slightly better. The cylinder heads alone flow nicely past the 650 whp mark without the need for aftermarket heads. The internals also hold more power stock 600whp max and the motor can be stroked to 4.5L and maybe even higher. It's more efficient too and more modern. Those are my reasons for doing this.

 

This is interesting. I called Courtesy Nissan Parts and they told me the motor mounts are the same for 2003-2008 but they said the crossmember is different on 07-08. That cant be true but I don't know anymore. I need to call someone else.

 

Whoever I talked with at Courtesy Parts was wrong. This is the definitive answer. http://my350z.com/forum/8139745-post4.html

These are the VHR, HR and DE motor mounts. The VHR and HR are identical so since the mounts work on the first gen platform 03-08 350z/G35 the VHR and HR bolt up to a first gen.

VHR motor mount

HR

DE

 

First gen is the same way. That's how I got my motor out both times. It was easier to leave the coilovers up in there but most of the rest comes down with 4 bolts.

 

Today I picked up a VHR HR transmission from Orlando FL from a member on my350z and brought it home. Long trip but it was worth it.

 

Now I'm subscribed.

what about fitting an 08 VQ40 to a first gen 04x?

 

Should have held out for an M56 motor swap.

 

Why not just swap in an ls2 and tranny....instant 12 sec car with a stock motor.
LOw 11's with a little modding. Its been done and there is a co. that makes all the harnesses and mounts. I've been toying with this swap...but only if I can keep the car street legal.

 

That's years away even if they are bringing one out. Prices on a used VQ37 are high enough even though it's been out 2 years already. Imagine a junkyard price on something that just came out like a VK56.

I also need a motor soon not later.

The only thing Infiniti is going to do next with the G is an hybrid G37. It's the only blank section in the factory service manual.
Personally I am not interested in the LS series.

I thought about emissions also. The EPA is stepping up inspections under Obama. My guess is as long as the ECU shows no codes and readiness of all systems it should pass.

 

Please let me know what you find. I got a OC engine and SPENT HOURS AND HOURS doing research, talking to the dealership, actually the best ones here in the bay area, talked with the CEO Dave M, From nissan sport magazine,

The swap is doable but for the price point not worth it at all.
Ill try to look for the link when I get home but if you have Magazine 11 and 12 i Believe there is talk in there. They swapped a HR in to a non hr z, and that should be cake right? well its not.


For us g guys, the most viable swap is the hr, it will bolt in but need minor work such as the starter is on the other side, and some minor custom fabbing. the cost for that would put me around 13k which is the cheapest for a stock swap I can find to pay someone else to do it.

I work about 60 hrs a week and dont have time to be out of my car for months, as the level of this swap is way beyond anything I have done before.

The 35hr doesn't make that much more power than a rev up, as for the cost.

The 37hr is definitely worth it and I am a strong believer in the great out of the box stock power, ( plus the vvel, im a old boosted 12 second vtec boy) and that motor makes great power with bolt ons, now hears the problem. and better MPG in a heavier car

The tranny is different length. All of the mounts are different. The wiring harness is different. the CAN BUS system will be very hard for it to function properly as it is set to work with the sensors from that car, the sensors from the 37 have different specs and perimeters from our 35's.


I was quoted around 15k for the job done right, And im talking to hopefully get it running, but they said the cost can go higher.( and most likely will as they dont know what other unknowns they will run in to.)


@15k guys Id take a RB26DETT swap, there some shops in texas and florida doing that swap right now all day long for about 15k.


So I suppose you can do the vq37hr as I wish I had did, but at around 15k with uncertainty that it will be 100% Like Factory, and maybe take even more labor, isnt worth it when you can get a STRONG AS HELL rb26dett and that stock motor ca easily get 600 whp in stock form.


But let me know your findings. I ended up kicking down 5500 for a fully built rev up motor NA to replace my oc. Didnt want to spend 10k on a OEM engine. And I went na because this is my daily and have no plans to boost. A built hi compressions na for 5500 is > 15k+ for a vq37hr



Heres the Link:

to my fellow g35 members EAT your hart out and have fun.

I thought id post my findings and share as my buddy Dave muramoto asked me to share my findings with anyone else wishing to do this swap.



So if you have plenty of time and the g is going to be strictly a track car, and don't mind the fact that for the same price and/or less work you can get a rb26dett to work this swap is for you.

 

People make it difficult because they choose to. It's simple if everything gets swapped over. Swapping and RB is a total mess and it's not practical since it's not ODBII and the stock ODBII ECU has to be kept to work together with a non ODBII motor/ECU. Not to mention that it doesn't bolt up at all unlike a G37 motor and trans that does.

I want full functionality and a factory fit and finish.
