Buy Toyota 1gr-Fe Used Engines For Sale

The 1GR-FE is a 4.0-liter V6 gasoline engine designed by Toyota for SUVs and RWD/4WD pickups. This 4.0-liter member of The Toyota GR engine family, together with 3.5-liter 2GR-FE, replaced the previous MZ V6 engines. The 1GR was first available in 2002 in the Toyota 4Runner and Land Cruiser Prado. After update in 2009 (Dual VVT-i 1GR-FE), the engine continues his life and still used in some four-wheel drive Toyota and Lexus vehicles like Toyota Tundra and Lexus GX 400.

The 1GR engine has an open-deck 60-degree V angle aluminum cylinder block with cast iron liners. Inside the block, there is a forged steel crankshaft with nine counterweights and four main journals, forged connecting rods, and aluminum alloy pistons. The engine uses oil jets mounted inside the engine block which sprayed oil to the bottom side of the pistons for temperature reduction. The piston skirts have a resin coating to reduce friction.

The engine has aluminum cylinder heads. The double overhead camshafts are driven by the primary and secondary timing chain. The primary timing chain drives the intake camshafts and then the intake camshaft drives the exhaust camshaft via the secondary chain. The first 1GR-FE engine (until 2009 model year) had the variable valve timing (VVT-i) on the intake. Cylinder heads for this engine have four valves per cylinder. The valves are actuated via shimless type valve lifters. The heads are covered by aluminum cylinder head covers.

There is a plastic intake manifold mounted on top of the engine. The intake is equipped with Toyota’s Acoustic Control Induction System (ACIS). The special air control valve varies the effective length of the intake manifold according to engine speed and optimizes the engine output. The Toyota’s Electronic Throttle Control System-intelligent (ETCS-i) system is also applied. The engine uses a sequential fuel injection system with twelve-hole fuel nozzles for each cylinder. The ignition is the Toyota’s DIS ignition. Each cylinder has individual ignition coil integrated into the spark plug cap. Each head has a stainless-steel exhaust manifold (header) with an integrated three-way ceramic-type catalytic converter.
