How does a 1000 wheel horsepower top mount turbo S54 swap into an E21 BMW 3-Series sound? Awesome
Here's an absolutely insane E21 BMW from our Scandinavian friends. For whatever reason, insane turbo BMW's tend to come from Scandanavia this one in particular from Jass Performance in Norway. The recipe is fairly simple, take a lightweight BMW and give it a crap ton of power. A 6 cylinder E21 is only about 2500 pounds meaning you combine that with a 1000 wheel horsepower from a top mount tubocharged built motor S54 and you have yourself a rocket ship.
The motor is mated to a 6-speed manual gearbox borrowed from an E39 M5 (the E46 M3 and E39 M5 6-speed gearboxes are the same thing). The turbo is a Precision 7654 pushing 29 psi of boost and the motor uses Bosch 1680cc injectors to flow the fuel necessary for all that air.
The car is simply insane and BimmerBoost loves it. Enjoy the video of it in action below.
