2000 Audi S4 with a 5.2 L V10

2000 Audi S4 with a 5.2 L V10

Martin Harp put a lot of work into his 2000 Audi S4. The car originally came with a twin-turbo 2.7 L V6 however he swapped it with a 5.2 L V10 from an Audi D3 S8. The V10 still runs the factory twin ECUs and features 5-into-1 headers and dual 3-inch exhaust. He accomplished this using parts from at least six Audi and VW vehicles from the same era. The V10 is mated to the factory 01E six-speed manual transmission which is pushed back two inches and features a B7 RS4 clutch. Martin retained the Quattro AWD drivetrain. The car rides on a rebuilt suspension with Verkline tubular subframes (front and rear) and “17z” Brembo disc brakes from a Porsche Cayenne. After finishing the powertrain and suspension work, Martin is ready to start work on the exterior. You can follow the progress on DeV10us B5 FB page or @harp_attack

  1. Damn! You put in work here! Did the V10 drop in the same engine mount bracket/holes?
    No issue with the wire harness hooking up to twins ecu??
    Weight difference on front any factor in steering?
    Sorry for questions, but this built is off da chain!
    Respex to da max!

    1. I had to make custom engine and trans brackets and the trans was pushed back 2 inches so shorter driveshaft as well. The front axles are currently at their limit and steering limit will be adjusted to prevent axles from popping out of the outer joint.

      The wiring was simplified using a custom jumper harness to get all the power, ground and signals sent where they were needed at both of the stock V10 ECUs.

      The car was weighed against a stock S4 with manual trans and it was actually 100lbs lighter. The V10 car had no front bumper and lighter suspension, seats and wheels at the time. No noticeable difference in handling compared to the already nose-heavy 2.7t it came with.
