We all know the engine determines the performance of a car, a good engine will lead to a good performance car and on the flip side a poor engine will lead to a poor performance car. All the same, it all begins with the type of engine running your car, that will decide if your car is capable of running great distances and on a tough terrain or it is just a city car that can take you to work and back. To give its customers a good performance car engine, Toyota came up with the 2rz engine.

The Toyota RZ engine family as well as the Trailgear parts are built in Japan and is a group of engines series that have a straight-4 piston. This family of RZ engine series is made up of a cast iron engine block combined with aluminum SOHC or DOHC cylinder heads to give it the needed physique. The engine series utilizes EFI fuel injection in combination with 2 or 4 valves per cylinder and forged steel connecting rods to give it a powerful working ability. This engine family is made through high-tech engineering where computers are used to ensure efficiency in design. One of the best engines in this family is the Toyota 2rz engine.

The Toyota 2rz engine is a 2.4 L (2,438 cc) version with a bore of 95 mm and a stroke of 86 mm. This engine has a wide range of combination of heads and fuel delivery systems available in the market for consumer preference. The SOHC engine option is made up of two valves per cylinder. The valve adjustment technology used is by shim over bucket giving the engine an average output of around 120 PS (88 kW) at 5,200 rpm. The first engine design originally had a carburetor induction system which was then upgraded to Electronic Fuel Injection that led to an E suffix added to the engine designation to match up with the new improvements. Toyota recommended the use of specified unleaded fuel with a rating of at least 91 RON to fuel this engine.

The engine was widely used to power many motor vehicle designs from like the 1989–2004 Toyota Hiace. A new engine model for the Toyota 2rz engine that combined the RZH1xx engine series together with the 2RZ-E engine variant was built in 1998 to power this model of cars. This new engine was more powerful and also more economical on fuel consumption. It gave the new Toyota Hiace a whole new touch from its predecessors.

Another model of the Toyota 2rz engine is the 2.4 L and 2,438 cc version, 2RZ-FE and 4RB1 or 4RB2 ( Chinese model). This engine has a bore of 95 mm and a stroke of 86 mm with a compression ratio of 9.5 to 1 and a total output of 142 hp (106 kW) at 5000 rmp.

The engine also has 160 lb•ft (217 N•m) of torque at 4000 rmp. This engine is engineered to get rid of balance shafts and combines four valves per cylinder. It is a DOHC engine that features valve adjustment technology by shim over bucket. Due to the great power and stability wielded by this engine, it was used to make the 1995–2004 Toyota Tacoma 4×2 and the 1998–2004 Toyota Hilux.
