Precision Sport Industries (PSI) has developed a sweet BMW M3 Coupe project. What makes this project so special are not the exterior or the interior kits, but what lies under the hood. under here, PSI has installed a G-Power SKII CS kit that increased the V-8 engine’s output from the standard 420 ponies to a supercar-like 600 horsepower. Peak torque has also been increased up from the standard 295 pound-feet to 427 pound-feet.

In order to obtain this amazing output the SKII CS kit includes an ASA T1-522 supercharger with the bracket system made from aluminum, a dual-flow air-intake box made from carbon fiber, a high-capacity air-to-air intercooler made from aluminum, eight fuel injectors with greater flow and eight racing spark plugs. There is also an Akrapovic Evolution Exhaust System that makes the engine sound better than ever. Capping off the build, PSI draped the air-intake tubes, resonator and valve cover in orange sherbert paint.

With the extra 180 horsepower, the M3 can now hit a top speed of 198 mph.

In order to handle the extra power, PSI also installed a set of 20-inch wheels, Eibach Race Springs and high-performance brakes. The interior received a series of new gauges — air-fuel ratio, boost and water temperature — developed in cooperation with VEI Gauges and 3D Design.

i love the fact that they have upped the torque so much. that is with almost 50% extra.

having a 200 MPH m3 will trick lots of racers. they will never suppose that your m3 will go that fast.

you got that right snow! imagine a m3 keeping up with a gallardo!

they should do something to the car to make it go 200+ MPH!
