In this episode Marty is recycling parts from our EJ powered VW Beetle project to get Water to Air Intercooling on his MR2. Then it's time to install an ECU to try and make it all work. More problems are discovered as the car is slowly transformed from a rusted nugget into a reborn JDM weapon (using copper pipes and bends from the hardware shop) ready to defeat Moog's Moon Buggy.
