Where to Buy a 4G64 Engine and What to Look For

If you're searching for a 4G64 engine for sale, you're likely replacing a worn unit or upgrading a Mitsubishi-powered vehicle or forklift. The 4G64 is a durable 2.4L inline-4 gasoline engine from Mitsubishi’s Sirius family, commonly found in models like the Eclipse, Galant, Pajero, L200, and various industrial forklifts¹. Whether you need a complete long block, short block, or fully assembled replacement, understanding your exact use case—vehicle type, condition preference (new, used, reman), and budget—is critical before purchasing.

Understanding the Mitsubishi 4G64 Engine

The Mitsubishi 4G64 is part of the broader Sirius engine series (4G6), introduced in the late 1980s as a reliable, fuel-efficient inline-four alternative to V6 engines in mid-sized vehicles and light commercial equipment 🏭. It features a cast-iron block with an aluminum DOHC 16-valve head, producing between 130–160 horsepower depending on application and tuning. Unlike its turbocharged sibling, the 4G63 (famous in the Eclipse GSX and Lancer Evolution), the 4G64 is naturally aspirated and designed for longevity rather than performance.

This engine is widely used across several platforms:

• Passenger Vehicles: Mitsubishi Eclipse (1995–2005), Galant (1997–2003), Pajero (V31/V33), Delica, Space Wagon
• Light Trucks: Mitsubishi L200/Triton, Dodge Stratus, Chrysler Sebring
• Forklifts & Industrial Equipment: Numerous OEM forklift models where durability under constant load matters more than peak power
• Aftermarket Applications: Used in kit cars, conversions, and Chinese SUVs like Great Wall Haval and Brilliance due to availability and low cost

Because of this broad usage, the term "4G64 engine for sale" can refer to very different products: a rebuilt long block for a 2001 Eclipse, a complete diesel conversion for a Pajero, or a brand-new assembly for a warehouse forklift. Knowing which version suits your needs prevents costly mismatches.

New vs. Used vs. Remanufactured: Pros and Cons

When exploring options for a 4G64 engine for sale online, three main categories dominate the market: new (often imported), used (salvaged), and remanufactured (rebuilt to specification). Each has trade-offs in cost, reliability, and warranty coverage.

✅ New 4G64 Engines

New units are typically manufactured in China or Turkey and sold through global suppliers such as Alibaba, Intella Parts, or CharNor. These may be labeled as "OEM factory" or "complete assembly." While they appear attractive at $600–$1,400, scrutiny is essential ⚠️.

• Pros: Full warranty (if offered), no prior wear, consistent build quality if from reputable source
• Cons: Often reverse-engineered copies—not genuine Mitsubishi; inconsistent machining tolerances; lack of proper break-in procedures
• Red Flags: No identifiable manufacturer name, missing serial numbers, vague documentation

🔧 Tip: Ask sellers for proof of origin, material certifications, and whether the engine was hot-tested before shipping. Genuine new Mitsubishi 4G64s are no longer produced for consumer vehicles, so most “new” units are third-party reproductions.

🛒 Used (Salvage) 4G64 Engines

Used engines come from junkyards, insurance write-offs, or dismantled imports—especially Japanese Domestic Market (JDM) units. Prices range from $300 to $900 depending on mileage, location, and demand.

• Pros: Lower price, real-world reliability history, often tested before removal
• Cons: Unknown maintenance history, potential hidden damage (e.g., overheating, oil starvation), limited warranty
• Best For: Budget-conscious buyers who can inspect or test the engine pre-purchase

📍 Geographic Note: JDM-sourced engines (from Japan) are popular due to strict emissions inspections and lower annual mileage. However, verify compatibility—some JDM variants have different emissions controls or sensors that may not work in North American or European markets.

⚙️ Remanufactured 4G64 Engines

Rebuilt engines are disassembled, inspected, and reassembled using a mix of new and refurbished parts to meet original specs. Companies like Powertrain Products, Lift Parts Warehouse, and Magna Engines offer these with warranties up to 3 years.

• Pros: Factory-level quality control, includes new gaskets, seals, water/oil pumps, timing components
• Cons: Higher cost ($2,500–$4,200), longer lead times
• Key Features to Confirm: Balanced rotating assembly, updated ECU mapping (if applicable), dyno testing records

⚡ Performance Tip: Some remanufacturers offer upgraded internals (forged pistons, performance camshafts) for higher output—ideal if planning mild tuning later.

Compatibility: Which Vehicles Use the 4G64?

Not all 4G64 engines are interchangeable. Variants exist based on year, region, fuel system, and balance shaft design. Below is a breakdown by application:

Vehicle Model	Years	Engine Code Variant	Notes
Mitsubishi Eclipse	1995–2005	4G64-S4M	Naturally aspirated; matches automatic/manual trans
Mitsubishi Galant	1997–2003	4G64	May include balance shafts; check transmission bellhousing
Mitsubishi Pajero / Montero	1999–2006	4G64-S4M	Often paired with 4-speed auto; some diesel conversions exist
Mitsubishi L200 / Triton	1996–2006	4G64	Rugged design; common in tropical climates
Chrysler Sebring / Dodge Stratus	1996–2000	4G64	Same base engine but different mounts/sensors
Forklifts (various)	1990s–present	4G64 PSI	No balance shafts; industrial cooling systems

📌 Critical Check: Always match the engine code (e.g., 4G64-S4M) and VIN-based lookup when ordering. A forklift-spec 4G64 lacks balance shafts and harmonic dampers needed for smooth operation in passenger cars.
