    • Someone swapped a GM LT4 V8 into an E92 M3 because they hate BimmerBoost

      You do not swap out the E92 M3 S65 V8 for another V8. You certainly do not do it for a Domestic V8 unless you just like to see the world burn. There is only one engine you consider swapping into that engine bay and it is the BMW S85 V10. Anything else is pure heresy.


      Despite whatever evil compelled DynoTorque UK to do this it certainly is unique. It is not exactly an OEM level swap though as the GM ECU is retained and they had to be creative to get things to work:

Running the GM ecu at the moment but with a Emerald ecu as the canbus interface ( run fans , steering etc ) . All fitted into car with no body mods at all , all std heat sheilds etc still in place . Sounds fantastic through the akrapovic system !!
      So while the engine fits without any issue there are some electronic issues. We do not get to see how the tach and interior electronics function with it but it seems to work well enough to drive and create a whole lot of smoke from the rear tires.

      With 650 horsepower and 650 lb-ft of torque out of the box there is plenty of power and plenty more on tap should one want it. C7 Z06's easily make 1000+ rwhp so this is one way to hit the four digit mark in an E92 M3 should one want to.

      Hopefully we get more videos of it in action showing the driveability.

        I mean... say what you want, but at least the car is running.

        guess they didn't want to bother with the rod bearings

        Ouch! But neither did they want high RPM.

        Unfortunately, an engine swap is probably the most reliable way.

        I see nothing at all wrong here. Go with what works. Function over form, purists will always hate something but when you're the one who has to drive it - reliability and avoiding S65 headaches and roadblocks to power is a big bonus.

        It does look good sitting in there. Almost factory appearing.
