BMW E46 M3 with a V10

BMW E46 M3 with a S85 V10

Driftworks owner Phil Morrison spent two years and £55,000+ on his daily driven 2001 BMW E46 M3 to swap in a S85 V10. At the time it was the most expensive and difficult engine swap they had attempted. The Pectel ECU and Cosworth Motorsports engine harness alone cost £15,000. The 5.0 L V10 taken from an E60 M5 makes 545 horsepower. They paired it with a E90 M3 six-speed manual transmission and Carbonetic Carbon limited slip differential.

    Hi,
    I am fan of Germain supercars specially E46 M3, for me it is the best in BMW series!
    Firstly i would like to thanks u & ur team for this fabulous work.
    it is very clean & professional.
    Hats of guys!

    hmm i have some questions:
    – With this swap on a BMW E46 M3 with S85 Engin swap, is it possible to put a Twin turbo(not a big one – an average twin-turbo)? does it have enought space??

    – Secondly, with this swap BMW E46 M3 with S85 Engin ONLY, can we drive the car daily? what problem can we get? heating problem maybe??
    And if yes, we can add a twin turbo, it will be possible for a daily drive car??

    Bcuz am thinking seriously to make this swap on my E46 M3, and for the budget it will not be a problem.

    Sheikh Abbas Yunnus Mussa Muhmmad Ali from Sweden!
