Toyota 5GR engine is the 2.5 Liter version of the GR family of engines. This version features a Dual Variable Valve Timing (VVT-i) on both camshafts but does not include direct injection but, instead, a multi-point fuel injection.

5GR engines are only built in China for vehicles specifically for the Chinese market. It shares the same engine design, architecture, and bore measurement as the 3GR-FE engine, which is also built in China to lower production costs and hold them on the same production line.

5GR engine is a member of the 8-piece family of GR engines.

Engine Specifiion and Design:

• Production Run: 2005 – Present
• Cylinder Bore Material: Aluminum
• Cylinder Head Material: Aluminum
• Configuration: V6
• Bore: 87.5 mm
• Stroke: 69.2 mm
• Valvetrain: DOHC with four valves per cylinder
• Displacement: 2.5 L (2497 cc)
• Compression Ratio: 10
• Weight: 380 lbs.
• Max HP: 194 HP at 6,200 RPM
• Max Torque: 179 lb-ft at 4,400 RPM

Toyota 5GR engines are designed for Rear-Drive longitudinal mounting, which is identical to the 3GR-FE engine, for which 3GR-FE machines are also substantially similar to the 2GR engines, perhaps with smaller displacement and a different layout. 5GR engines produce 194 HP at 6,200 RPM, 179 lb-ft of torque, and a compression ratio of 10.0.

Toyota 5GR-FE’s cylinder block is made from a lightweight cast Aluminum alloy. Within the bores are spiny type cast-iron cylinder liners made into the block. This surface creates an irregular texture to allow a better adhesiveness between the Aluminum cylinder block and the liners.

The 5GR engine has a bore of 87.5 mm and a shorter stroke compared to its identical counterpart, 3GR, of 69.2 mm. The banks of the cylinder have a 60-degree in V arrangement, which are then spaced in an equal offset of 36.6 mm.
