This Seat Arosa Mk2 was built by Darkside Developments of Barnsley, UK.
The standard engine was replaced by a 2.0 L 16v turbo diesel inline-four, modified by Darkside. Its output is 406 horsepower and 500 lb-ft or 528 horsepower and 680 lb-ft with nitrous. It is equipped with modified stock pistons, Rosten H-beam rods, ported head, race camshafts, custom intake and manifold, 2000 bar injectors, Darkside GTD2872VR turbocharger, and Revo direct port nitrous system.
Power goes to the wheels through a billet flywheel, sintered clutch, built 02M six-speed transmission with a Quaife LSD, and custom driveshafts.
It accelerates 0-60 mph in 2.26 seconds, passes 1/4 mile in 10.49 seconds at 130.27 mph or 9.722 seconds at 146.74 mph on nitrous, and reaches 164.031 mph in half a mile for 30% nitrous oxide.
