Another exciting build is underway in the workshop, with Ben working his magic on this BMW performance project. The car is now equipped with a PSR 6870 GEN2 turbocharger paired with a PSR 50mm ProGate, a serious hardware combination designed for high airflow, strong boost control, and reliable power delivery.
This isn’t just a visual upgrade — it’s a major step toward transforming the vehicle’s performance potential.
The Hardware That Matters
🔥 PSR 6870 GEN2 Turbo
The 6870 GEN2 is known for:
Excellent top-end power capability
Efficient compressor design for strong airflow
Quick response for its size when matched correctly
Ideal for high-horsepower street and track builds
This turbo allows the engine to move significantly more air, which is the foundation for producing big power safely when paired with proper supporting mods and tuning.
🎯 PSR 50mm ProGate
Boost control is just as important as boost production. The 50mm ProGate ensures:
Stable boost pressure
Reduced boost creep
Consistent performance under load
Better tuning accuracy
A quality wastegate setup like this keeps the turbo system controlled, reliable, and predictable — especially at higher boost levels.
Why This Setup Works So Well
When a large-frame turbo like the 6870 GEN2 is paired with a properly sized external gate, the result is a system that can:
✔️ Flow enough air for major horsepower gains✔️ Maintain stable boost at high RPM✔️ Handle future power upgrades✔️ Deliver a strong, aggressive powerband
This BMW is being built not just to look impressive, but to perform at a level that matches serious enthusiast expectations.
What’s Next?
With the turbo hardware now in place, the next stages typically involve:
Fuel system support
Intercooling efficiency
Custom ECU tuning on the dyno
That’s where the real magic happens — turning hardware potential into real, usable performance on the road or track.
Stay tuned for dyno results — this setup has all the ingredients for a seriously quick BMW.
