Lexus V8 Engine for Sale | OEM Used Toyota

Toyota's flagship V8 family from 1989-2011 across three variants. The Toyota / Lexus UZ engine family is Toyota's flagship V8 engine family from approximately 1989 through 2011, serving across Lexus and Toyota's premium and heavy-duty applications. The UZ family is widely regarded as one of the most reliable production V8 engines ever made, with many examples delivering 300,000-500,000 plus miles of service when properly maintained. Three variants: 1UZ-FE 4.0L (1989-2002) the original UZ V8 for Lexus LS400 / GS400 / SC400 applications, 2UZ-FE 4.7L (1998-2011) the larger truck/SUV variant for Land Cruiser / LX470 / Tundra / Sequoia applications, and 3UZ-FE 4.3L (2001-2010) the modernized variant with VVT-i for GS430 / SC430 / LS430 / GX470 applications. Specifications: 90-degree V8, aluminum DOHC 32-valve heads, VVT-i on later variants, port fuel injection (NOT direct injection), timing belt driven.

Three variants with different displacements and applications. 1UZ-FE 4.0L (1989-2002): original UZ family V8, introduced 1989 with Lexus LS400 launch (the engine that established Lexus's reputation for refinement). 3,968 cc displacement, 250 HP early (non-VVT-i) up to 290 HP later VVT-i, applications: Lexus LS400 (1989-2000) / GS400 (1997-2000) / SC400 (1991-2000), aluminum block. 2UZ-FE 4.7L (1998-2011): larger truck/SUV variant, introduced 1998 for Land Cruiser / LX470. 4,663 cc, 271-282 HP, applications: Toyota Land Cruiser (1998-2007) / Lexus LX470 (1998-2007) / Toyota Tundra (2000-2009) / Toyota Sequoia (2001-2007), cast iron block (for durability under load). 3UZ-FE 4.3L (2001-2010): modernized variant with full VVT-i. 4,293 cc, 290-300 HP, applications: Lexus GS430 (2001-2007) / SC430 (2001-2010) / LS430 (2001-2006) / GX470 (2003-2009), aluminum block, refined character with full VVT-i for improved torque curve.

Widely regarded as one of the most reliable production V8 engines ever made. The UZ V8 is widely regarded as one of the most reliable production V8 engines ever made. Reliability factors: over-engineered design (Toyota's design philosophy of conservative tuning and robust components produced an exceptionally durable V8); 300,000-500,000 plus mile capability (many UZ examples deliver 300,000-500,000 plus miles of service when properly maintained with timing belt and oil changes); smooth refinement (the original 1UZ-FE in the LS400 established Lexus's reputation for refined power delivery); established Lexus reputation (the 1UZ-FE in the 1989 LS400 was instrumental in establishing Lexus as a credible luxury brand by demonstrating Toyota-quality reliability with luxury refinement); strong aftermarket support (UZ rebuild kits, performance parts, and conversion supplies widely available; the 1UZ-FE has a strong enthusiast following for engine swap projects); Toyota / Lexus parts availability (OEM parts remain readily available through Toyota / Lexus dealer channels).

UZ family era and modern UR family successor. The Toyota / Lexus UZ V8 family (this listing) is the OEM Toyota / Lexus V8 from approximately 1989-2011. The Lexus SC400 water pump from is the OEM water pump for the 1UZ-FE engine in SC400 application (the LS400 / SC400 / GS400 share the same 1UZ-FE engine architecture and water pump system). The Lexus LS460 4.6L engine from is the modernized 1UR-FSE V8 engine that succeeded the UZ family in Lexus LS460 applications (introduced 2007 for fourth-generation LS), representing the next-generation Lexus V8 with direct injection technology. Cross-batch Lexus engine context: LS460 4.6L 1UR-FSE V8 from (the modernized successor to UZ family with direct injection), SC400 water pump from (the cooling system component for 1UZ-FE applications), and (this listing) UZ V8 engine family covering 1UZ / 2UZ / 3UZ variants.

UZ family uses timing belt requiring replacement every 90,000 miles. The Toyota / Lexus UZ V8 family uses a timing belt (NOT a timing chain), and timing belt replacement every 90,000 miles is CRITICAL maintenance. Failure to replace the timing belt at the recommended interval results in timing belt failure, which damages the interference engine (the pistons strike the valves causing catastrophic damage including bent valves and potentially damaged pistons). Timing belt replacement cost: approximately $800-1,500 at Toyota / Lexus dealers or qualified specialty shops, including water pump replacement (recommended at same service since water pump is behind timing belt). Skipping this service to save cost is one of the few ways a UZ engine can fail prematurely; with proper timing belt service, UZ engines routinely deliver 300,000-500,000 plus miles.

Specific Lexus and Toyota applications per variant. 1UZ-FE 4.0L applications: Lexus LS400 (1989-2000) the flagship Lexus sedan that launched the brand; Lexus GS400 (1997-2000) the sport sedan; Lexus SC400 (1991-2000) the personal luxury coupe. 2UZ-FE 4.7L applications: Toyota Land Cruiser (1998-2007) the flagship full-size SUV; Lexus LX470 (1998-2007) the Lexus-badged Land Cruiser; Toyota Tundra (2000-2009) the full-size pickup; Toyota Sequoia (2001-2007) the three-row full-size SUV. 3UZ-FE 4.3L applications: Lexus GS430 (2001-2007); Lexus SC430 (2001-2010) the convertible personal luxury; Lexus LS430 (2001-2006); Lexus GX470 (2003-2009) the mid-size SUV. Each variant has the correct engine for its specific application; cross-application requires careful verification of bellhousing, mounts, and accessory drive.

Timing belt + water pump, cooling system, VVT-i inspection. After acquiring a used UZ V8 engine, budget for timing belt + water pump service first (if not recently done): $800-1,500 for full timing belt service including water pump, tensioner, idler pulleys, and accessory belt; this is the most critical UZ maintenance item. Cooling system service: $300-600 for thermostat, hoses, and coolant flush as preventive maintenance. VVT-i solenoid inspection (later variants): test VVT-i operation, replace solenoids if codes present. Strict 5,000-7,500 mile oil change intervals with Toyota-approved oil. Iridium spark plug replacement every 100,000 miles. With this maintenance schedule, expect 300,000-500,000 plus miles of reliable service. The UZ family rewards proper maintenance with exceptional longevity.
