Description
This adapter converts the factory throttle body on the 2JZ-GTE non-VVT-i & VVTi engine to a Bosch 74mm DBW (drive by wire) throttle body. This adapter is the interconnect between the throttle body and the factory 2JZ-GTE intake manifold. This may be necessary when installing some aftermarket engine management units.
Warning: The Bosch DBW Throttle Body cannot be controlled by a factory ECU. You must have an aftermarket ECU in order to control it.
The PHR 74mm Bosch Drive By Wire Throttle Body Adapter is machined from 6061 Billet Aluminum, and anodized black for corrosion and oxidation protection. Not to mention it looks killer.
The OEM Toyota throttle body is 65mm in diameter. The larger body opening of the Bosch 74mm allows more air to flow into the engine. This increase in airflow can lead to higher horsepower and torque, especially at higher engine speeds.
Additionally, the throttle response tends to be quicker which is very important in performance driving scenarios where quick acceleration changes are needed.
AÂ larger throttle body can help achieve higher peak power outputs. It’s a part of a broader strategy to enhance the overall performance of the engine.
