    • Speedtech's EFR7670 based N55 turbo kit hits 556 rwhp on an F22 M235i with an E50 blend, JB4, and Port Injection

      Speedtech is pretty quiet overall but their N55 turbo kits are making some noise. Check out this Asian F22 BMW M235i that the owner equipped with the Speedtech N55 manifold and a BorgWarner EFR7670 turbo charger.


      The numbers:

      BM3 HCP Custom Map Flash Only 98+Meth 488whp / 62KGM

      BM3 HCP Backend Flash + JB4 + PI Kit + E50/98ron Mix 556whp / 79KGM


      Not bad right? 556 wheel horsepower is a major upgrade for this M235i and it is working well with port injection on the stock internals and a BMS JB4.

        These EFR kits are really impressive lately.

        I have seen nothing but good things about the speedtech kit. Their n54 kit should definitely change up the n54 single turbo market.

        Should be this summer. No it will be for Garrett frame sized. Twin scroll t4 or t3 option and VERY reasonable pricing.

        Sweet. A t3 would be fine for many.

        Twin scroll bottom mount at a very attractive price point. Targeted to be cheaper than the n55 kit.

        You would have to ask the tuner for that info. @lfelunden

        i make 600-650 at 23ish on my daily speedtech kit. its a beast. for PWG can be more challenging dialing in the tune and the install is harder than PS2.
