This build has been going on for over a year, but it’s no easy task to make a monster like this. The mad scientist behind this Frankenstein has dropped an S62 engine from the E39 M5 and then slapped a twin-turbo kit on it. To provide some insight as to what exactly this all means, here’s a little background information on the two cars.
In stock form, the S62 M5 engine produces nearly 400 horsepower and 369 ft-lbs of torque. This is a lot of horses, even when placed in a 4-door saloon car that tipped the scales at 3,800 pounds. 0-60 could be achieved in just 4.9 seconds. If you took off the speed limiter, you could reach a top speed of 187mph.
Now the E30 M3 only weighed 2,844 lbs. With its 192hp Inline-4, you could run it up to 60mph in around 6.5 seconds. Back when the E30 was produced, that was very fast for a car. Backed by big names like Prodrive and AC Schnitzer, the E30 M3 was a very successful race car, competing in anything from road races to rally competitions.
With that background, you can understand that putting an M5 engine into the lighter weight M3 should deliver ridiculous levels of acceleration. But putting a twin-turbo kit onto the 4.9-liter V8 behemoth will surely reach levels of insanity that are only known by those in an asylum. The car isn’t finished yet, but you can follow the build here.
