VQ37VHR Engine for Sale: JDM Infiniti Q70 and M37 3.7L V6

Shopping for a VQ37VHR that won't leave you guessing about its condition? This one's a low-mileage JDM motor pulled from a 2014 to 2019 Infiniti Q70. The VVEL system is intact; it's compression-tested, and it ships with a 90-day warranty. It also fits the M37, so you've got options depending on which car you're working on.

Engine specs

VVEL explained

VVEL stands for variable valve event and lift. It's Nissan and Infiniti's system for adjusting how far and how long the intake valves open, which changes depending on how hard you're driving. Older VQ engines, like the VQ35DE, didn't have this. It's part of why the VQ37VHR runs smoother and pulls harder than the engine it replaced.

What this VQ37VHR fits

This engine shows up across a handful of Nissan and Infiniti models, so it's worth checking the exact chassis before you buy.

Infiniti Q70 and M37

The VQ37VHR fits the Q70 directly, since that's where this specific engine came from. It's also the same engine used in the M37, so this listing covers both cars without any modification needed.

370Z, G37, Q50 and Q60

Nissan and Infiniti also put the VQ37VHR in the 370Z, G37, Q50, and Q60. The core engine is shared, though wiring harnesses and some accessories differ between models. If you're not sure which version you need, reach out before ordering. For other Nissan and Infiniti engine options, you can browse JDM Infiniti VQ engines in our catalog.

VQ37VHR vs VQ35HR vs VQ35DE

These three engines get mixed up a lot, so here's the short version.

The VQ35DE was solid for its time, but the VVEL-equipped engines that followed it run more efficiently and make more usable power across the rev range. If you're upgrading from a VQ35DE, the VQ37VHR is a common swap target, though it does need extra wiring work.

Condition: low mileage and compression tested

Every VQ37VHR we list goes through a compression test first. If it doesn't pass, it doesn't get sold. We check mileage where we can and report it as is, not rounded down to look better. Low mileage still means used, but it also means you're not buying something close to failing.

What's included

• The VQ37VHR long block

• VVEL components intact

• Wiring harness where applicable

• Sensors attached to the engine

• Mileage and test documentation

Looking for a transmission to go with it? We stock a CD009 six-speed to match this engine, so you're not stuck sourcing it separately.

Frequently asked questions

Does the VQ37VHR fit a 370Z?

Yes. The 370Z used this engine along with the G37, Q50, and Q60. Wiring can differ slightly between models, so double-check your harness setup.

What's the difference between VQ37VHR and VQ35HR?

The VQ35HR is the earlier 3.5L version with VVEL. The VQ37VHR bumped displacement to 3.7L and added a bit more power. They're related but not interchangeable without swapping supporting parts.

Can I put a VQ37VHR where a VQ35DE used to be?

It's a common swap, especially in 350Z and G35 builds, but it's not a straight bolt-in. You'll need to account for wiring and some mounting differences. Check out the VQ35DE it replaced for more on the differences between the two.

Do you sell Nissan transmissions separately?

Yes, we carry a range of Nissan transmissions including the CD009, so you can match one to your engine if you need a full swap.

How do I confirm this VQ37VHR fits my car?

Match your VIN and engine code against what's listed here, or send us a message directly. We'd rather confirm before the sale than deal with a mismatch after.
