Toyota Mark X
Together with 4GR-FSE, in 2003, Toyota introduced a 3 liter 3GR engine. It has replaced the worldwide popular 2JZ-GE. This engine uses the same aluminum 60° V6 cylinder block as 2GR. However, the cylinders diameter of 3GR is smaller – it is 87.5 mm. Also, these engines feature different cooling systems.
Toyota 3GR engine uses two DOHC cylinder heads equipped with variable valve timing system (Dual-VVTi) on intake and exhaust camshafts. The camshafts have been slightly changed. 3GR engine uses variable length intake manifold ACIS and multi point injection system.
The engine version with direct fuel injection system D4 was also being produced. These engines were called 3GR-FSE. In such engines, the compression ratio is increased to 11.5. Also, intake ports are modified, pistons are of the optimized shape, and spark plugs are different.
As a result, 3GR is similar to 2GR, but with a smaller displacement.
This engine was designed for the Lexus cars with an index of 300, as well as for Toyota vehicles.
Besides 3GR, Toyota GR series includes the following models: 1GR, 2GR, 4GR, 5GR and 6GR.
Toyota 3GR engine problems and malfunctions
This engine is not very different from 2GR, so both these engines have similar problems. This is, for example, the problem with the fifth 3GR cylinder. Learn more HERE.
This 3-liter engine was designed for comfortable driving in the city and on the highway. To make it faster, a lot of money is needed. You can buy some performance parts, such as cold air intake and performance exhaust system. This will increase the engine power a little, but your car will still be slow.
You may buy TOMS 3GR supercharger kit. This kit is installed on the stock internals and it may provide more than 300 horsepower and a torque of 390 Nm. Buy 3” performance exhaust system and you will get a little more power. You should not make something even more powerful (especially 3GR turbo); it is easier simply to sell your car and buy a more powerful one.
