Toyota 1GR-FE Engine

The Toyota 1GR-FE 4.0 engine is a powerful and reliable V6 powerplant commonly found in heavier duty Toyota vehicles, such as the 4Runner, Tacoma, and FJ Cruiser. It produces superior performance with a 300 horsepower output while offering improved fuel economy over other engines thanks in part to its advanced Variable Valve Timing (VVT-i), which ensures optimal combustion efficiency.

The 1GR-FE is designed for proven reliability; it features an oil filter that helps regulate oil pressure and minimize dirt and debris damage to your engine’s internals, along with durable cylinder block construction using iron sleeves to reduce weight compared to previous Toyota engines. All of these features make the 1GR-FE an excellent choice for drivers who need dependability under heavy workloads.

The GR family also includes the 4GR-FSE, 2GR-FE, 3GR-FE, 5GR-FE and 6GR-FE engines.

In 2002, a new 4.0-liter unit debuted on the Land Cruiser Prado 120 SUV. By design, it is a classic for its time V6 engine with a cylinder angle of 60°. It has distributed fuel injection, an aluminum block with an open cooling jacket and cast-iron liners, aluminum DOHC cylinder heads without hydro-compensators, and a chain drive timing. The first generation of this engine was equipped with VVTi phase controllers only on the intake shafts.

In 2009 the second generation debuted on the Land Cruiser Prado 150. The main difference was the presence of VVTi phasing regulators on all camshafts. Also most versions of the engine were equipped with hydro-compensators for valve timing.

Problems & disadvantages of the Toyota 1GR-FE

• Toyota 1GR-FE head gasket failure is one of the more common issues on the 4.0L engine and can be identified by white smoke from exhaust, coolant loss, misfires and milky looking oil.
• Replacement of the head gaskets cost around $50-100 for parts but labor to replace them may add up to about $800-1200.
• Water pump problems are also common in Toyota 4.0 engines with symptoms such as coolant leak, overheating and steam/smoke from engine indicating a problem that needs fixing quickly before it leads to further damage like head gasket failures; replacement costs around $100 plus labor at about $250-500 for installation.
• Ignition coil issues are not too uncommon either with misfires, rough idle/stumbling acceleration or loss of power being potential signs; replacing all 6 coils will cost approximately between 90$ -150$, while spark plugs should be changed every 80 000 – 100 000 miles at an approximate price tag of 50$.

Engine 1GR-FE Tuning

• Toyota Racing Development (TRD) offers a compressor kit for the GR series engines, based on an Eaton M90 supercharger with intercooler, ECU and other engine components.
• The kit produces approximately 300-320 hp and excellent traction at all ranges. More powerful kits are available but require more work to install.
• Oil consumption is not usually an issue with this engine when 5w30 oil is used and changed every 7000 kilometers or filled up to 400 grams above the upper mark of the dipstick.
• If properly operated and serviced regularly, 1GR-FE can last up to 1 million kilometers in total use time
