If you're aiming for a road-legal, supercharged 1MZ-FE build, it's entirely possible to achieve a noticeable boost in power while staying within CARB-legal or emissions-compliant boundaries. The key is sticking to certified parts, primarily the TRD supercharger kit, which is emissions-certified for select model years and delivers solid gains in both horsepower and torque. When combined with a few legal supporting mods like a CARB-approved intake, high-flow catalytic converter, and a cat-back exhaust system, you can safely enhance performance without compromising street legality.

The 1MZ-FE engine came in two main variants that impact your baseline numbers. Early non-VVT-i versions, found in models like the late-’90s Camry and Avalon, start at around 190 horsepower from the factory. Later VVT-i-equipped versions, such as those in 2000+ Camry, Avalon, and Lexus ES300, produce around 210 horsepower stock. These engines are a solid foundation for a supercharged build, offering smooth power delivery, decent fuel economy, and proven reliability, making them ideal candidates for street-driven performance upgrades.

To safely push close to 300 horsepower at the crank with a supercharged 1MZ-FE while staying as emissions-compliant as possible, a few critical upgrades are necessary beyond the basic TRD supercharger setup. One of the most important is installing larger fuel injectors, which can deliver the additional fuel required under boost. Fortunately, some injector upgrades are considered CARB-legal when paired with the TRD supercharger kit, making them suitable for road use in emissions-regulated areas.

An intercooler is another key component for power and reliability, as it reduces intake air temperatures and improves performance under sustained load. However, most intercooler systems are custom-fabricated and not CARB-certified, which makes emissions compliance more difficult. To support all of these mods, a custom ECU tune or a piggyback tuning system is recommended to optimize air/fuel ratios, ignition timing, and boost response. Since the stock ECU has limited tuning capability, a well-chosen piggyback system can safely push performance without triggering emissions-related issues. With this setup, reaching the 300 hp mark is realistic while keeping the build mostly road-legal.
