E46 BMW M3 Gains V8 Power Unit From E92 Gen Model

While the E46 M3 was one of the best all-time performance cars of its generation, there are still those who would consider its 338 horses to be insufficient in today’s era.

Luckily, there are people like Tyler from Technica Motorsports who can do something about that. He even let Matt Farah drive this E46 M3 project car, powered by the S65 V8 unit from the newer E92-generation model.

It also features the E92 M3’s 6-speed manual gearbox to help control the 414+ HP now running through its veins. We do learn that they’ve managed to get a little bit more power from the 4.0-liter V8, but otherwise the engine remained stock, as did the rest of the car – mostly.

During his drive, Farah found the V8-powered E46 M3 to be very smooth and extremely fast in a straight line. He did have a slight issue with the steering, but we’ll let you find out why that was by hearing Tyler explain the problems they ran into while modding this car.

The cost of jamming an S65 V8 into an E46 M3? Around $50,000, and you have to provide the engine.

    The concept is nice, but you can’t ask $50k for this job when you can probably buy an entire E92 M3 for two thirds of that sum.

    Can I just get the E92? Or the E60?

    • Belthronding Tinuviel

      e60 v10 is just a beast,you challange it and wake the wolverine up. it ll be coming for you.
      e92 v8 m3 is not a match for e60 v10.

      • SteersUright

        Yes but e60 V10 is notorious for breaking down, considering it likely wont make it too far the e92 might be easier to live with (even with its own rod bearing issues). BMW seems to no longer be building very well designed engines for the long term it seems. Sad, I’d love either car you mention otherwise.

        • Belthronding Tinuviel

          v10 m5 is really hard for to live it as you mentioned above.
          the (positive) difference of e92 is gearbox actually. 7 speed DKG is comfortable,fast shifting and newer than v10’s old smg3 which is quite angry,bit slower and uncomfortable for city.
          but potential rod bearing issues is same for both car.

  • Pros:
    It’s a BMW M

    You have to (potentially) ruin a E46 M3
    You have to (potentially) ruin a E92 M3

    And the result: only about 70-80 more HP.

    I’d say, if you really want more, go for a BMW turbo I6 engine and blow it up insanely.

      That would be a waste of a decent engine.
