Leib Engineering Will Turn Your V8 M3 Into A 600bhp Monster

We may have waved goodbye to the mighty E93 V8 BMW M3, but that hasn't stopped tuners Leib Engineering having a bit of a play. In this upgrade kit, the 4.0-litre V8 gets a dirty great G-Power SK II CS supercharger bolted on to it, which ups the power to a brutal 600bhp when combined with an upgraded fuel pump, air intake, injection system and tweaked ECU.

A set of KW DDC coilovers help tame that power, and a fruity new exhaust with the intriguing addition of a steering wheel-controlled valve lets you alter the shoutiness of your M3 at will.

The exterior has been pretty much left alone, save for the peculiar decision to remove the M3 badges (presumably Leib wants to make the M3 into a sleeper), and a new set of 19-inch BMW rims nicked from the 1M.
