Engine compatibility between models? VQ37VHR
Hi guys,
I own a 2008 G37S Coupe. I am in the process of locating an OEM engine, to replace the built components on my original.
According to the well-meaning guys at salvage dealerships reading from a compatibility listing , my particular year is a standalone engine. They 'claim' I can only use a 2008 engine.
Of course I don't want to invest in a $3000 engine to find out it won't work (for whatever reason). I also am aware that a simple oil pan swap or something negligible may be the only distinctions.
Does anyone have REAL experience in the arena? No conjecture, but side by side comparisons or swaps?

Thanks in advance. I have many more options if I knew I could substitute elsewhere.

VQ37VHR
VQ37VHR
It was the first production engine from Nissan using VVEL. It has an increased compression ratio of 11.0:1, with 3,696 cc (225.5 cu in) displacement (95.5 mm bore and 86 mm stroke), while redline remains at 7600 rpm. It is rated at up to 337 PS (248 kW; 332 hp) at 7,000 rpm and 37.2 kg·m (365 N·m; 269 lb·ft) at 5200 rpm. Although the engine gains only 0.2 kg·m (2 N·m; 1 lb·ft) peak torque over the VQ35HR and this higher torque arrives at 5200 rpm vs. 4800 in the VQ35HR, the torque curve itself is improved and flattened via VVEL variable valve timing for better throttle response and low rpm torque. The VQ37VHR engine has been touted by car magazines and reviewers as an improvement over the VQ35HR engine mostly adding much refinement and smoother engine operation, especially at high rpm where the VQ35HR engine was frequently criticized for NVH and sounding strained, harsh and loud.
It is fitted into the following vehicles:
2008–present Infiniti G37 Coupe- 330 hp (246 kW)
2008–present Nissan Skyline V36 370 GT Coupe- 330 hp (246 kW)

I just did a quick parts search with Used Parts Search - Standard Auto Wreckers . usually when parts are interchangeable their website will cross reference other parts to see if they can find a compatible part. I searched for a 2008, 2009, and a 2010. All of which came up with their own year and engine types. The only exception was that I found a 370z 2009 engine that also came up and was compatible with a 2010 G37 engine. So it could mean that the salvage guys are right or wrong? Pray to the interweb gods to find your solution.

Have you tried contacting GTM or Stillen? They've dealt with a lot of VQs I'd assume they know the minute differences. The only changes I know of are small and negligible (different P/S pumps, oil/water cooler on later models, etc).

I haven't contacted either Sam at GTM, or even Vinny at VTR. They would be a good source.
See what I mean? The boneyard books claim non-interchange, however, I'd like to think it's negligible. I'd LIKE to think...

Coop you use any VQ37VHR out of any year G or 370z. You can also use a HR bottom end you would just have to bolt your heads up to it.
If your Interested in buying a built block let me know I will be willing to sell mines because I am looking to do something crazy with my spare long block.

How sure are you of the compatibility? I'm getting opportunities for engines locally and far away... just not from a 2008.
I can't imagine there would be distinctions, but no one wants to find an engine casting with a motor mount 2" away... LOL!

No built block wanted. Not now, but that's an opportunity. Thank you!

I have a spare long block that came from a 2009 G37 I am 100 % sure I can put this in my 2010 370z it's sitting in my garage .A friend of mine also has a 2008 G37 block in his 370z. It's the same block and heads for all VHR engines all years.

^^^ Thanks THis is good news It opens up a world of possibilities.
The car is sitting at The Shop, and we've simply put it on the back burner. It's getting time to turn on the gas...
Thank you.

Jimmy called Vinny from Vinny Ten Racing. He also verified the G37 and 370Z engines are compatible.
Jimmy didn't ask: Would the G37X AWD engine be the same? Is there a different oil pan? Or worse (like a BMW) a different engine casting?
Thanks to all who are helping in this matter.

Update: One of the forum members contacted me. He had a long block with less than 10K on it from a 2012 G37X.... I've since purchased it and I delivered it to The Shop this morning.
It has a lower casting which has a hole cavity for the AWD axle which goes through the engine. However.... that is also a removable casting 4" below the saddle which holds the crank halves together. This important saddle does not (can not) get swapped.
We are very optimistic that the lower casting from my unit will interchange with this. Not 100% but it sure looks so.
Either that or we get out the torches....
Jimmy's schedule allows him to get the existing engine out early next week. At that point we'll know for sure. Here's to being resourceful.
More news as I do. Once the other engine is out we can see how extensive the work on that would be.
FYI.
