Important Fitment Information

The engine code is extremely important, but matching VQ37VHR does not automatically guarantee that every external component will be identical.

JDM and USDM applications can differ in sensors, wiring connections, accessories, brackets, intake components, exhaust components, engine mounts, oil pans, emissions equipment, and other vehicle-specific parts.

For many installations, the JDM engine serves as the replacement long block while selected components from the original USDM engine are transferred to the replacement motor.

Before ordering, compare your original engine and vehicle application with this unit. If you need assistance, contact J-Spec Auto Sports with your year, make, model, drivetrain and VIN.

What Is Included?

This listing is for the VQ37VHR engine only.

Recommended Service Before Installation

Even a quality used replacement engine should be properly inspected and prepared before installation.

Because the engine is already outside the vehicle, this is also the ideal time to service accessible wear items. Doing so can reduce the chance of paying significant labor costs later.

Before installation, we recommend having a qualified technician:

• Compare the JDM engine with the original USDM VQ37VHR.
• Inspect accessible gaskets and seals for leakage.
• Inspect valve cover gaskets.
• Inspect timing chains, guides, and tensioners.
• Inspect the water pump and cooling-system components.
• Inspect or replace spark plugs as needed.
• Inspect ignition coils, boots, and electrical connectors.
• Check VVEL-related connections and components.
• Transfer required USDM sensors, accessories, and brackets.
• Install fresh engine oil and a quality oil filter.
• Prime the lubrication system before initial startup.
• Fill the engine with the manufacturer-specified coolant.
• Properly bleed air from the cooling system.

VQ37VHR First-Startup Procedure

Proper first startup is especially important after replacing an engine.

Before starting the VQ37VHR, confirm that all electrical, fuel, cooling, vacuum, intake, and exhaust connections are properly installed. Also verify that the engine contains the correct amount and specification of fresh oil.

The lubrication system should be properly primed before normal startup so the engine is not immediately operated under load without adequate oil circulation.

After startup, monitor:

• Oil-pressure warning indicators
• Engine temperature
• Oil leaks
• Coolant leaks
• Fuel leaks
• Vacuum leaks
• Abnormal noises
• Idle quality
• Check-engine light
• Diagnostic trouble codes

Allow the engine to reach operating temperature while closely monitoring the cooling system.

After the engine cools, recheck the oil and coolant levels and inspect the installation again for leaks.

Professional Installation Recommended

J-Spec Auto Sports recommends installation by a qualified technician familiar with Nissan and Infiniti VQ-series engines.

The installer should compare both engines before installation and determine which original USDM components need to transfer to the JDM engine.

After installation, the vehicle may also require applicable electronic throttle, idle, VVEL, or other relearn procedures according to the correct factory service information.

Frequently Asked Questions

What is a VQ37VHR engine?

The VQ37VHR is Nissan’s naturally aspirated 3.7-liter V6 from the VQ engine family. It uses DOHC cylinder heads, variable valve timing, and Nissan’s VVEL variable valve lift technology.

What does VVEL mean?

VVEL stands for Variable Valve Event & Lift. The system controls intake valve operation to improve engine response and performance across different operating conditions.

Is this engine a VQ37VHR or VQ35HR?

This engine is a VQ37VHR 3.7L V6. It should not be confused with the earlier 3.5L VQ35HR.

Will this VQ37VHR fit an Infiniti G37?

The Infiniti G37 is one of the primary VQ37VHR applications. However, exact fitment depends on model year, body style, drivetrain, and the external components installed on the engine. Compare your original engine before installation.

Does this engine fit an Infiniti Q40?

The Infiniti Q40 used the VQ37VHR in applicable configurations. Verify your vehicle information and required external components before ordering.

Will it fit an Infiniti FX37, EX37 or QX50?

The VQ37VHR was used in applicable versions of these Infiniti models. However, external components can vary by chassis and drivetrain. Verify compatibility before installation.

Is this the same engine used in the Nissan 370Z?

The Nissan 370Z also uses a VQ37VHR-family 3.7L engine. However, do not assume complete engine assemblies are identical or directly interchangeable. Oil pans, accessories, brackets, intake/exhaust components, sensors, wiring, and other external parts can vary by application.

Can I transfer parts from my original engine?

Yes. Transferring original USDM components is common when installing JDM engines. Your technician should place both engines side by side and transfer any components required for the specific vehicle.

Should I replace the valve cover gaskets before installation?

Inspect them carefully. If they show signs of leakage or deterioration, replacing them while the engine is outside the vehicle can save substantial labor later.

Should the timing chains be replaced?

They should at least be inspected along with the guides and tensioners. Replacement should be based on their condition and the appropriate service requirements.

Should I replace the spark plugs?

We recommend inspecting the spark plugs before installation and replacing them when necessary. Also inspect the ignition coils, boots, and electrical connectors.

Should I prime the engine before the first startup?

Yes. Proper lubrication is critical. The engine’s lubrication system should be primed using the appropriate service procedure before normal operation.

Does the cooling system need to be bled?

Yes. Air trapped in the cooling system can contribute to overheating and poor coolant circulation. Properly fill and bleed the cooling system after installation.

Is the transmission included?

No. This listing is for the engine only. The transmission is not included.

Is this VQ37VHR compression tested?

Yes. This particular engine has been compression tested by J-Spec Auto Sports before sale.
