Toyota GR engine

1GR-FE The 1GR-FE is the version, designed for longitudinal mounting in RWD and 4WD pickup applications. It has a bore and a stroke of . Output is at 5200 rpm with of torque at 4000 rpm when tuned for 87 octane, and at 5200 rpm with at 3700 rpm when tuned for 91 octane. This engine features Toyota's VVT-i, variable valve timing system on the intake cam and a compression ratio of 10.0:1. Service weight, including fluids, is . An updated version of this engine features Dual VVT-i, increasing output to at 5600 rpm and at 4400 rpm on 87 octane. Inside, the 1GR uses a "taper-squish" combustion chamber design with matching pistons to improve anti-knocking and engine performance, while also improving intake and fuel efficiency. Toyota adopted a siamese-type intake port, which reduces the surface area of the port walls and prevents fuel from adhering to such walls. This engine has special cast-iron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block. In the event of cylinder wall damage (scoring, deep protrusions, etc.), the entire cylinder block must be replaced. For increased block rigidity, the 1GR also receives a high temperature plastic insulator/protector, which fills the empty space between the outer portion of the cylinders and block material common to open deck engines. For increased cooling efficiency, the 1GR employs water passages between the bores of the engine. There are two such passages for each bank for a total of four. This reduces cylinder hot-spotting and keeps combustion chamber temperatures more uniform. A bolt-on TRD supercharger kit was available on the Tacoma and FJ Cruiser but has been discontinued by Toyota. The new 2015 Toyota HiLux receives a slightly different version of the single VVT-i engine, with the only change being a removal of an air intake baffle tank being replaced by a conventional air filter housing to intake pipe to surge tank style. The new intake pipe now contains resonators. Power output is unchanged. First generation 1GR-FE variants with single VVT-i features Toyota's Acoustic Control Induction System. This system consists of a bulkhead to divide the intake manifold into two sections, and an intake air control valve (in the bulkhead) to control its effective length. When the engine is operating at moderate revolutions and under high load, an actuator closes the intake air control valve to increase the effective length of the intake manifold. At other operating conditions, the intake air control valve opens up to reduce the effective length of the intake manifold.

2GR-FE The 2GR-FE is a version. Bore remains at ; but stroke is reduced to . Reported output varies depending on the vehicle application, but is approximately to at 6200 rpm with to of torque at 4700 rpm on 87 octane (R+M/2). This version features Toyota's Dual VVT-i, variable valve timing on both the intake and exhaust cams. The cams are driven using a timing chain. Valves are driven by roller-follower rocker arms with low friction roller bearings, and a unique, concave cam lobe design to increase valve lift over the traditional shimless lifter type system of the 1GR-FE. This increases overall cylinder head height to accommodate the slightly taller roller rocker system. Moreover, the cylinder head is segmented into 3 parts: valve cover, camshaft sub-assembly housing, and cylinder head sub-assembly. As such, this valvetrain is used across all other GR engines with Dual VVT-i. Its service weight is . This engine has a robust aftermarket community and is a candidate for engine swaps, such as into the SW20 MR2. It has primarily been used in K platform vehicles.

This system combines direct injection (/min injectors) with traditional port injection (/min injectors). Direct injection lowers the tendency to knock (detonation) and increases performance by reducing the charge intake temperature. Traditionally, direct injection engines require an in-engine mechanism such as swirl ports or specific piston crown shapes to increase air turbulence in the engine. These are in place to help achieve a homogeneous air-fuel mixture inside the cylinder at low RPM and high load, but these mechanisms inhibit performance at higher engine speeds. In the 2GR-FSE, port injection is used considerably to achieve the correct mixture without having in-engine restrictions, meaning the engine achieves specific power near the top of all naturally aspirated production gasoline engines in the world (/L, in the Mark X). Toyota also developed a new type of injector for this engine. The dual fan spray pattern of the direct injectors is perpendicular to the piston travel with wide dispersion in the cylinder, which aids air and fuel mixture and therefore increases power and efficiency. The port injectors not only help improve the power and efficiency but they also help improve emissions, especially in the first 20 seconds after start-up (when the catalytic converter is in its warm-up stage). Compression ratio is 11.8:1. The 2GR-FSE engine is rated at at 6,400 RPM and at 4,800 RPM. The engine's service weight is .
