Find your 4.0 Liter engine

4.0-Liter Engines: The Toyota 4.0-liter engine made appearances in the Toyota F, GR, V, and UZ engine families running as a popular Toyota engine size for decades. Among the different Toyota engine families, the company found the most success with the GR series engines, which were designed for longitudinal mounting in rear-wheel drive vehicles and pickups. This engine features Toyota’s VVT-I variable valve timing designed to improve engine performance, and this series of motors eventually replaced the older MZ models. It should be noted that the Toyota 4.0-liter engine came in V6 and V8 configurations.

• 1GR-FE - The 4.0 V6 Toyota engine is a widely popular Toyota engine that was used among rear-wheel drive Toyota vehicles. This engine initially featured a variable valve timing (VVT) system on the intake side and was later updated to a dual (VVT) system with changes to the timing of the intake and exhaust valves which increased the power rating to 270 hp from the original 240 hp rating. This 4.0 Toyota engine also has a variable intake manifold called Toyota’s acoustic control induction system (ACIS). The 4.0-liter V6 Toyota engine was used for sale in the 2002-present Toyota 4runner, 2007-2011 Toyota Land Cruiser, 2004-2015 Toyota Tacoma, 2005-2014 , 2006-2017 Toyota FJ Cruiser, and the 2012-present Lexus GX 400.
