The price for a replacement INFINITI G35 engine varies widely, but you can expect roughly $1,000 to $4,000 for the engine itself, with installed costs typically ranging from about $3,000 to $8,000 depending on labor, parts, and location. This covers used, remanufactured, and rebuilt options, with OEM new units being rare and usually more expensive.
Engine price ranges
Prices shown below reflect common options for the G35’s 3.5-liter V6 powerplant. They refer to the engine block itself and do not include labor, taxes, or core charges.
- Used/salvaged long block: $800–$1,800
- Remanufactured long block: $2,000–$4,000
- Rebuilt/restored engine: $1,500–$3,000

Prices can fluctuate based on year, mileage, core availability, and seller. Always verify exactly what is included (timing components, accessories, ECU) before purchase.
Installed and related costs
Installing a replacement engine involves more than the part itself. The following figures cover typical labor and ancillary costs that affect the total bill.
- Labor for installation: $500–$1,500
- Core charge (where applicable): $100–$500
- Shipping or delivery to the shop: $0–$200
- Additional parts and services (timing kit, water pump, seals, fluids, ECU programming): $100–$1,000
The total installed price often falls in the $3,000–$8,000 range, depending on the shop, region, and any extra work needed beyond a straightforward engine swap. Getting multiple quotes is advisable.
Buying options and warranties
Choosing the right option involves balancing price, reliability, and coverage. Consider these factors when shopping for a G35 engine replacement.
Choosing a supplier
Buy from reputable sources—OEM distributors, established remanufacturers, or well-reviewed salvage yards. Check what is included in the price (core return, gaskets, belts, sensors, and ECU) and whether a warranty applies.
Warranty and coverage
Look for a warranty that covers at least 90 days to one year for the engine itself, with clear terms on what constitutes a warranty claim. Confirm whether the warranty follows the engine or the vehicle and whether it requires professional installation.
Compatibility and documentation
Verify exact engine compatibility with your G35’s model year and transmission. Bring your VIN and request documentation showing engine code, mileage at time of sale, and any included components. Ensure you receive installation guidance or professional support if you’re not doing the swap yourself.
Summary
For a replacement INFINITI G35 engine, expect part prices in the roughly $800 to $7,000 range depending on condition and source, with installed costs typically between $3,000 and $8,000. The best approach is to determine your priorities (cost vs. longevity), compare multiple reputable suppliers, and secure a solid warranty. Factor in labor rates in your area and any additional parts your specific build requires.
