STAGE 4 HYBRID TURBO 400WHP CAPABLE

Introducing the Hybrid Turbo That Could!

This exceptional turbo has the potential to deliver an impressive 400 WHP, making it the perfect match for your Audi A4. Why is this turbo a game-changer? Your stock block can handle a maximum of 350 tq before risking damage, so having a turbo that seamlessly integrates with your stock hardware is essential!

No need to worry about complex coolant lines or exhaust modifications—simply remove your old turbo and install this massive powerhouse! Designed to utilize your actual 1.8T power band, this turbo spools up at just 3000 RPM and delivers robust performance all the way to 6500 RPM, ensuring a safe and exhilarating driving experience.

Unlike larger turbo setups that typically spool at 5000 RPM, which can overwhelm your stock valvetrain that is limited to 6800 RPM, our hybrid unit maximizes your usable power while staying within safe limits for your connecting rods. Enjoy true performance without compromising reliability—choose the hybrid turbo for a thrilling driving experience that keeps the fun factor high!
