This article will describe attributes of the original 1GR-FE engine and include details of the differences with the upgraded, 'dual VVT-i 1GR-FE' engine in turn. 1GR-FE Toyota engine. Engine Trans. Years Peak power Peak torque. Toyota Mk.7 Hilux 4.0-litre petrol V6 5sp auto 2005-15 175kW at 5200rpm 376Nm at 3800rpm. #1 · Nov 8, 2011. In December of 2010 my VVT oil line burst, only my AC light was indicating a malfunction. While enroute to the dearlership the car would not accelerate and was making odd noises. Once in service I was told that the line burst and there was no oil in the vehicle, and that there was a recall (which I had never been notified of). The dual VVT-i engine is a continuation of the previous engine, which uses VVT-i technology. VVT-i or variable valve timing with intelligence is a machine that relies on changes in valve timing based on engine speed. The narrow or wide opening of the engine valve depends on the engine speed. The VVT-i system works by using an oil-pressure actuator to adjust the location of a camshaft. This results in better low-end and high-end performance and overall engine efficiency. Early 1GR-FE engines only used VVT-i on the intake camshafts. That changed in 2009, when Toyota added Dual-VVT-i to the 1GR-FE in the 4Runner and FJ Cruiser.
