Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Transform your B58-powered BMW with the Pure Turbos Pure800 Stage Two hybrid unit. This high-flow, direct-replacement performance turbo is engineered for rapid spool, huge headroom and OEM-like manners on the road. Ideal for fast road, track day and drag builds, it is the proven choice for enthusiasts chasing serious gains on the F-series M140i, M240i, 340i and 440i platforms.

We run the Pure800 on our own B58 projects and customer cars, and the feedback is consistently outstanding. Expect crisp response, reliable power delivery and repeatable dyno numbers when paired with the right supporting hardware and calibration. If you are searching for an uprated B58 turbocharger, performance turbo for M140i, turbo swap for M240i, 340i tuning turbo or 440i power upgrade, this is the solution.

What Makes Pure800 Stand Out

  • Custom billet compressor wheel for excellent airflow and efficiency
  • Optimised turbine wheel for strong midrange and relentless top-end pull
  • Precision CNC-machined housings for perfect sealing and factory-like fitment
  • High-speed VSR balanced for smooth operation and long-term durability
  • Direct replacement unit for B58 F-series applications with no fabrication required

Real-World Performance

  • 586 whp on pump 98 RON with appropriate supporting modifications
  • High 500s to low 600s whp on 99 RON with meth, upgraded HPFP and full bolt-ons
  • 630 whp on race fuel or 98 RON where fuel system becomes the limiting factor
  • Up to around 700 whp on an E50 blend with methanol and an upgraded HPFP
  • 734 whp on E85 with Stage 2 HPFP and full bolt-ons at 30 to 32 psi
  • Approximately 542 whp at 23 psi
  • Quick spool from roughly 3200 rpm for strong midrange punch

These numbers make Pure800 one of the most capable and confidence-inspiring B58 performance turbos for mixed street and circuit use.
