Pure Turbos BMW F-Series B58 PURE 800 Turbo (M140I/M240I/340I/440I)

Developed and manufactured at Pure Turbos' own HQ specifically for the B58 platform, this is genuinely one of the most reliable turbos on the market at this power level. On 93 octane fuel alone with supporting modifications, expect around 560-586whp. Push further with an upgraded HPFP, an E50 fuel blend, and methanol injection, and around 700whp is achievable.

Real-world documented results back this up in detail: 586whp on 98 RON pump fuel, high 500s to low 600s whp on 99 RON pump fuel with meth, an upgraded HPFP, and full bolt-ons, 630whp on race gas/98 RON pump fuel (limited by the fuel system), 700whp on E50 with meth and full bolt-ons, and as high as 734whp on E85 with an upgraded Stage 2 HPFP and full bolt-ons at 30-32psi. This is a genuine core-exchange upgrade, built on your existing turbo housing.
