The Power of the B58 Supra: A Street Racing Legend

The Toyota Supra B58 has quickly become a favorite among street racing enthusiasts, thanks to its powerful B58 engine and impressive tuning potential. Built in collaboration with BMW, the fifth-generation Supra (A90) features a turbocharged 3.0L inline-six B58 engine, delivering 382 horsepower in stock form—but with the right mods, this beast can push well beyond 500+ HP. Whether you’re into drag racing, track days, or just showing off at car meets, the B58 Supra is a force to be reckoned with.

Why the B58 Supra Dominates Street Racing

The Toyota Supra B58 stands out for its perfect balance of power, weight, and handling. Unlike many heavy muscle cars, the Supra’s lightweight chassis and rear-wheel-drive setup make it agile and responsive. The B58 engine is also incredibly robust, with a closed-deck block, forged crankshaft, and strong internals that can handle serious power upgrades.

Key performance features of the B58 Supra include:

• Twin-scroll turbocharger for reduced lag and instant throttle response
• Direct injection & port injection for optimal fuel delivery
• ZF 8-speed automatic transmission (with manual option in newer models) for lightning-fast shifts

With simple bolt-on mods like a downpipe, intake, and tune, the B58 Supra can easily hit 450+ WHP, making it a street racing monster.

B58 Supra Internals: Built for Power

One of the biggest reasons the B58 engine Supra is so popular in the tuning scene is its strong internal components. Unlike some engines that need immediate upgrades to handle extra boost, the B58’s internals are designed to withstand serious power.

Key B58 Supra internals include:

• Forged crankshaft – Handles high RPM and big power
• Aluminum made-inside engine – Gives extra power inside ultra boost
• Forged connecting rods & pistons – Durable enough for 600+ HP builds
• High-flow cylinder head – Optimized for turbocharging

Because of these strong internals, the B58 Supra can handle 600+ HP on stock components with proper tuning. For those chasing even bigger numbers, aftermarket rods, pistons, and turbo upgrades can push the B58 past 800+ HP for all-out drag racing builds.

Street Racing Mods for the B58 Supra

To unlock the full potential of the Toyota Supra B58, enthusiasts often turn to these popular upgrades:

• ECU Tune (BM3, MHD, JB4) – Eliminate stock barrier as well as enhancing boost
• Catless Downpipe – Improves exhaust flow for more power
• Upgraded Intercooler – Keeps intake temps low for consistent performance
• Hybrid Turbo / Big Turbo Kit – Takes horsepower to the next level
• E85 Ethanol Fuel – Maximizes performance through fuel with superior octane

With these mods, the B58 Supra can outrun many high-end exotics in street races, making it a favorite for those who love speed without breaking the bank.
