This solution encompasses the components required to modify a Toyota 22R engine into a 22RE engine. The primary difference between these engines lies in their fuel delivery systems: the 22R utilizes a carburetor, while the 22RE employs electronic fuel injection (EFI). The kit typically includes parts such as a fuel injection manifold, fuel injectors, a fuel pump, an electronic control unit (ECU), wiring harnesses, and various sensors. For instance, installing this hardware will fundamentally alter how fuel is introduced into the engine’s combustion chambers.
The appeal stems from the enhancements EFI offers over a carburetor. EFI generally provides improved fuel efficiency, enhanced engine performance (particularly in terms of throttle response and power delivery), and reduced emissions. Older vehicles originally equipped with the 22R engine can benefit from these modern advancements, leading to a more reliable and environmentally friendly operation. Moreover, the conversion allows for better adaptability to varying altitudes and weather conditions, which a carburetor may struggle with.
