Pure800 Stage Two B58 Hybrid Turbocharger for BMW G‑chassis and Toyota GR Supra MK5

Unlock huge real-world performance with the Pure800 Stage Two hybrid turbocharger for the 3.0‑litre B58. This direct‑fit, factory‑frame unit delivers rapid spool‑up, massive midrange torque and top‑end power while retaining stock‑like manners for road use. Proven on our own builds and countless customer cars, it is the go‑to choice for drivers who want serious gains without sacrificing drivability.

Ideal for G‑series BMW models and the GR Supra MK5, the Pure800 is engineered to achieve 600+ wheel horsepower with the correct hardware and calibration. It is a bolt‑on turbocharger solution that maintains OE connections yet flows far beyond the standard charger thanks to a high‑efficiency billet compressor wheel, reworked turbine and precision‑machined housings.
