Installing a TRD supercharger on the Toyota 2AZ-FE engine is a highly effective and emissions-compliant way to significantly boost performance while maintaining street legality. The factory TRD kit, part number PTR29-21000, was designed for the Scion tC but is compatible with other 2AZ-FE-equipped vehicles such as the Camry and RAV4. The kit includes an Eaton M62 roots-style supercharger, a cast intake manifold, mounting brackets, a bypass valve, a properly sized drive belt, and a TRD piggyback ECU. Most importantly, it carries a CARB Executive Order (EO D-425-33), meaning it is legal for use in California and other CARB-compliant states as long as all emissions equipment is retained.
Although the original TRD kit did not include an intercooler, adding a front-mount intercooler (FMIC) is both beneficial and legal when installed correctly. A bar-and-plate FMIC, combined with custom 2.25–2.5” charge piping, silicone couplers, and appropriate mounting brackets, helps reduce intake temperatures and improve performance under boost. The key to legality is ensuring the MAF sensor, EVAP lines, PCV system, and O2 sensors remain untouched and fully functional. With proper routing and installation, the intercooler does not affect emissions equipment and can be used without jeopardizing compliance.
To support increased airflow and fuel demands under boost, fuel system upgrades are necessary. These include 440–550cc injectors and a high-flow fuel pump such as the AEM 340LPH or Walbro 255. These components are not emissions-controlled and are legal for street use. Additionally, installing a wideband O2 sensor and AFR gauge is recommended for monitoring air-fuel ratios during tuning. The TRD piggyback ECU retains full OBD2 functionality and does not disable emissions systems, which ensures the vehicle remains legal for inspection and road use.
Exhaust system upgrades can also be made while staying compliant. A CARB- or EPA-certified high-flow catalytic converter can replace the factory cat for better flow, and a 2.5” cat-back exhaust system can be installed as long as it meets local noise ordinances. O2 sensors must remain in their original locations and operate properly to avoid triggering a check engine light. By following these guidelines, you ensure that all emissions monitors are set and the car can pass smog or roadworthiness inspections in most regions.
With all legal modifications in place, TRD supercharger, intercooler, fueling upgrades, and compliant exhaust, a 2AZ-FE engine can safely produce around 235–245 horsepower at the crank, or approximately 195–205 horsepower at the wheels. This represents a gain of over 60 horsepower compared to stock, all while retaining daily drivability, reliability, and full emissions compliance. For enthusiasts who want more power without compromising legality, this setup provides an ideal balance of performance and street-readiness.
