Unlocking True Potential: Why the B58 Is a Tuner’s Dream
The B58 engine, BMW’s inline-6 turbocharged powerhouse, has earned a reputation for performance, reliability, and responsiveness. Found in models like the M240i, 340i, Supra, and more, the b58 is not just a capable engine—it’s a platform begging for modifications. At Rvng RaceWorks, we specialize in bringing out the best in your B58 through real-world-tested mods that deliver gains you can feel.
Intake Systems – Feed Your B58 More Air
The stock B58 intake system is good—but not great. Upgrading to a high-flow intake transforms throttle response and turbo efficiency. A performance B58 intake lets the turbo breathe easier, reduces restriction, and delivers a more aggressive induction sound. At Rvng RaceWorks, our proprietary intake designs are engineered to optimize airflow and thermal efficiency, giving your B58 more air and, ultimately, more power.
Downpipes – Let the B58 Exhale Properly
One of the most popular B58 mods is a high-flow or catless downpipe. The factory downpipe creates significant backpressure, limiting spool and power. Swapping it for an upgraded B58 downpipe reduces turbo lag, improves exhaust flow, and unlocks horsepower gains—especially when paired with a tune. The B58 responds extremely well to exhaust mods, and our downpipes are precision-built to deliver results without sacrificing fitment.
Tunes – The Heart of B58 Performance Upgrades
While hardware upgrades are essential, tuning is where the B58 really shines. A proper B58 tune adjusts boost, fuel, and timing maps to unleash the full potential of your mods. With a custom or off-the-shelf tune from Rvng RaceWorks, your B58 can gain upwards of 80-100 horsepower over stock—on pump gas. For those looking to push further, E30 or full E85 tunes take the B58 to a whole new level of performance.
Charge Pipes and Intercoolers – Reliability Meets Power
The stock B58 charge pipes are plastic and prone to cracking under high boost. Upgrading to aluminum or silicone B58 charge pipes ensures durability and maintains consistent pressure. Coupling this with an upgraded front-mount intercooler dramatically improves intake air temps, reduces heat soak, and keeps your B58 performing at its peak—even in aggressive track conditions. These upgrades aren’t just about power—they’re about keeping your B58 reliable under pressure.
Turbo Upgrades – For the Power-Hungry B58 Owner
For enthusiasts chasing serious horsepower, upgrading the turbo is a game-changer. The stock B58 turbo can deliver impressive gains with bolt-ons and a tune, but there’s a limit. A hybrid or full-frame B58 turbo unlocks 600+ horsepower potential. At Rvng RaceWorks, we support a range of turbo options that bolt up with minimal hassle while offering maximum gains.
Fueling Mods – Supporting Big B58 Builds
Once you go beyond basic bolt-ons, the B58 fuel system becomes a limiting factor. Upgraded fuel pumps, port injection kits, and flex-fuel kits allow your B58 to safely run ethanol blends and support high horsepower goals. Whether you’re targeting 500 or 700+ horsepower, our fueling solutions ensure your B58 gets the right amount of fuel every time you hit boost.
Suspension and Drivetrain – Putting B58 Power to the Ground
What good is power if you can’t use it? Enhancing the B58’s supporting systems—like drivetrain mounts, limited-slip differentials, and coilovers—helps translate your performance gains into real-world speed. At Rvng RaceWorks, we offer components that complement your B58 power mods by improving traction, handling, and launch capability.
