The 22R-E was a 2.4-liter four-cylinder engine produced and designed from Toyota between 1984 and 1994. It was used in several Toyota vehicles including the Celica, the 4-Runner, and the Toyota Pickup. Without modifications, the engine produced 112 horsepower and 143 pound-feet of torque. There are a number of performance aftermarket parts available for the 22R-E engine which increase horsepower when installed. Some of these parts replace existing engine components, while others bolt on to the engine itself.
Replace the 22R-E air intake with a performance aftermarket air intake. First, locate the factory the air intake within the engine bay and open the intake housing if your vehicle has one. Next, remove all components connecting the factory air intake to the engine. Gently life the factory air intake out of the engine bay and set it aside. Lastly, simply place the aftermarket air intake in the vacant area where the factory air intake resided, replace all connections, and replace the intake housing.
Replace the 22R-E headers with performance aftermarket headers. First, lift the engine slightly out of the engine bay so that you can reach all of the header connecting hardware. Remove all connecting hardware and disconnect the factory headers from the engine itself. Align the aftermarket headers with the connecting brackets and re-connect all connecting hardware. You may need assistance with this step in order to keep the headers aligned with the connecting hardware.
Replace the 22R-E exhaust system with a performance aftermarket exhaust system. First, lift the vehicle using either a hydraulic lift or a manual jack and tire chocks. Make sure that the vehicle is secure before continuing. Remove the connecting hardware from the stock exhaust system and remove the stock exhaust system from the underside of the vehicle. Line up the new exhaust system with the bracket connections and re-connect the connecting hardware, taking care not to over-tighten. Lastly, connect the new exhaust system to the headers.
Install a supercharger or turbocharger system. The specifics of installing one of these systems varies drastically from one manufacturer to another, but they are typically very demanding installations that many involve lifting the engine, punching or drilling holes into the engine, and replacing many other engine components.
