Full build breakdown, dyno data & tech inside.
The BMW M240i, known for its agility and fun-to-drive nature, has hidden potential waiting to be unleashed. Through a complete upgrade solution from JA Performance, we have transformed it into an ultimate performance machine, boasting over 926 wheel horsepower.
At the heart of this build is JA Performance’s “Big Turbo Kit”, specifically engineered for the BMW B58/B58TU engine. This is not a simple turbo swap, but a complete systemic solution that addresses the heat, piping, and strength limitations of OEM-frame upgrades.
Turbocharger Core: Features the JA7275 high-performance turbo. Its 72mm forged compressor wheel and optimized 75mm turbine provide a solid foundation for the 1000hp goal.
Supporting Components: The kit includes a high-flow exhaust manifold, reinforced intake piping, a massive front-mount intercooler, and all necessary hardware for a true “bolt-on” and reliable installation.
After professional ECU tuning and rigorous testing, this M240i delivered astonishing results on an AWD Mustang dynamometer:
Peak Wheel Horsepower: 926.5 whp @ 6500 rpm
Peak Wheel Torque: 880 lb-ft @ 5000 rpm
Peak Boost Pressure: 44 psi (approx. 3.0 bar)
Achieving 1000hp is about sustainable power, not just peak numbers. The JA7275 turbo utilizes a dual ceramic ball bearing CHRA, ensuring rapid response and ultimate durability at extreme RPM. Paired with the massive front-mount intercooler from the JA kit, intake temperatures are kept in check under high boost, preventing heat soak—this is the key to consistent high-power delivery.
JA Performance specializes in providing complete high-performance turbo kit solutions for the BMW B58 platform. Our philosophy is “Systematic Solutions,” delivering full kits that include vehicle-specific exhaust manifolds, reinforced piping, and all necessary hardware to unlock immense potential with exceptional fitment, finish, and reliability.
