2GR

2GR-FE

thumb|200px|2GR-FE engine in the 2008 Lexus RX 350

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.

2GR-FSE

thumb|200px|2GR-FSE engine in the 2008 Crown

The 2GR-FSE is a engine used in the Lexus IS, GS, Mark X and Crown and incorporates Toyota's latest D-4S twin injection fuel system. 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 .
