    • BimmerBoost member's E39 M5 with an S52 turbo engine swap goes over 900 horsepower

      Many of you are wondering why someone would ditch the S62 5.0 liter V8 under the hood of the E39 M5 for a smaller BMW inline-6 motor. Well, these results make a strong argument for such a swap. This E39 M5 belongs to BimmerBoost member @Omni. You can read all about his decision to do the swap in a past article.


      Even at lower power levels than the car runs currently it was a beast. @Omni beat up on a tuned Cadillac CTS-V Wagon as well as a tuned F13 M6 Gran Coupe. With the car now making over 800 to the wheels it is safe to say he can take on even more stout competition.

      He is running a Precision 6266 turbocharger at 35 psi of boost. 100% methanol is injected in a direct port setup. A water and methanol blend is utilized as well before the compressor. Tuning is by @NickG of Technique Tuning and done on the stock DME no less.

      The result? 813 horsepower and 819 lb-ft of torque at the wheels which works out to comfortably over 900 at the crank. However you feel 800+ horsepower at the wheels is serious power and this may be the world's most powerful E39 at this point.


      Simply incredible results and props to @Omni for continuing to push the boundaries.

        Just search my name on youtube, Eric Adrian
        Here is a handful of videos at all different boost levels, 600-750whp. Didn't have any races on the 800+ setup.

        Awesome numbers, but is a M5 a M5 without a M5 engine?

        It's certainly a valid question. Is it an M car without an M motor?

        It's a sweet swap no doubt. Love that it has a BMW heart unlike the E39 M5 2JZ swaps. If you are going to swap in an iron block I6, it better be BMW's: http://www.bimmerboost.com/content.p...sepower-on-E85

        does a car become an M car if you put an M motor in it?

        No.

        You answered your own question though. An M car is an overall package. Including the motor. Which should be the heart of the experience...

        Pretty sure a s52 is an m engine but I get what your saying. Is a e30 m3 with an s54 no longer an M car? lol
