"Needed a engine for my F-150. Nationwide verified the exact match by VIN, and it showed up at my mechanic's shop palletized and ready to drop in. Saved over $2,500 vs the dealer."

Engines for every major make

Infiniti's engine lineup is built on Nissan's acclaimed VQ and VR platforms. The VQ35HR/VQ37VHR 3.5L/3.7L V6 powers the G35, G37, Q50, Q60, Q70, QX70, and QX50 (pre-2019) — this is one of the most celebrated V6 engine families in automotive history, earning Ward's 10 Best Engines 14 consecutive years. The VR30DDTT 3.0L twin-turbo V6 (300–400 hp) powers the Q50 and Q60 Red Sport. The QX80 uses the VK56VD 5.6L V8 with VVEL (Variable Valve Event & Lift). The 2019+ QX50 uses the VC-Turbo (KR20DDET) 2.0L variable compression ratio engine.

We carry every Infiniti engine platform from the combined Nissan/Infiniti inventory — one of the deepest Japanese luxury pools available.

Common Infiniti Engine Issues

These are the most frequent reasons Infiniti owners need a replacement engine.

VQ35DE/VQ35HR (G35/M35/FX35) — Gallery Gasket Oil Leak: The VQ35 in the G35 and FX35 develops an oil gallery gasket leak between the upper and lower oil pans where they meet the block. This leak is age and mileage related, difficult to access, and compounds with valve cover gasket leaks and front timing cover leaks to create a multi-point oil loss situation. Replacement is common at 120K+ miles when repair costs approach engine value.

VQ37VHR (G37/Q50/Q60/370Z) — Concentric Slave Cylinder & Oil Consumption: The 3.7L VQ37 can develop oil consumption from valve guide wear at higher mileages, and manual transmission applications commonly fail the concentric slave cylinder (CSC) inside the bellhousing. The 3.7L is otherwise very robust — most replacements are from vehicles with 150K+ miles or significant oil neglect.

VR30DDTT (Q50/Q60 Twin-Turbo) — Water Pump & Turbo Wastegate: The VR30 twin-turbo can develop water pump bearing failure and turbo wastegate actuator rattle on earlier production units (2016–2018). Later revisions improved both components. A replacement engine from later production eliminates both concerns with updated hardware.

VC-Turbo KR20DDET (2019+ QX50) — First-Generation Complexity: The VC-Turbo is the world's first production variable compression ratio engine. While technologically impressive, its mechanical complexity (an eccentric actuator arm changes the piston stroke) means repair costs are high when issues arise. When repair costs exceed the value of the repair on this mechanically complex platform, a replacement engine from our growing donor pool is the practical path forward.

Infiniti Engine — Quick Answers

Are Infiniti and Nissan engines the same?

Infiniti uses Nissan engine platforms. The VQ37VHR in the Q50 is the same family as the 370Z. The VR30DDTT twin-turbo is shared between Infiniti and Nissan applications. Combined Nissan/Infiniti inventory for fast sourcing.

Is the Infiniti VQ engine reliable?

The VQ35 and VQ37 are among the most reliable V6 engines ever built. They regularly exceed 200K miles with basic maintenance. Most replacement demand comes from oil leak accumulation on high-mileage units rather than catastrophic internal failure.

Do you carry the VC-Turbo engine?

Yes — we stock the KR20DDET VC-Turbo for the 2019+ QX50. Due to the specialized nature and limited donor pool, we recommend quoting early.
