Pure Turbos BMW G-Series B58 PURE 650 Turbo (M240I/M340I/M440I/540I/Supra)

This is Pure Turbos' proven mid-tier turbo offering for the G-Chassis B58 Gen 2 platform and the A90/A91 Supra, with real-world results speaking for themselves. On a stock fuel system, one documented M340i build recorded 542whp and 731Nm of torque. Push further with E85 and supporting modifications, an intake, catless downpipe and exhaust, an upgraded intake manifold, higher-flow injectors, an upgraded low-pressure fuel pump, and Stage 3 transmission tuning, and the same platform has been documented at 623whp/596wtq.

Available as a new aftermarket housing (OEM design), meaning genuinely no core exchange is required, or as a standard core-exchange upgrade built on your existing turbo housing, whichever suits your timeline and budget. Each unit features Pure Turbos' billet compressor wheel, larger and stronger turbine wheel, and upgraded bearing housing for genuine durability under sustained load, all VSR balanced for smooth, reliable performance.
