Garage Revolution has prepared a very cool Mazda RX-7->ke344 for the World Time Attack Challenge. Their RX-7 is powered by a 13B turbo engine that has received a 50mm exhaust manifold, 80mm front pipe, 80mm full titanium exhaust, custom airbox, custom cooling ducts for turbine, MoTeC M2R ECU and boost control solenoid. The result is an impressive 600 HP and with a total weight of 2204 lbs you can only imagine the level of performance it will deliver.
