The conversion you are referring to only converts a 200mm car to 220mm. The 220mm class did not take off as well as many had hoped and only a few (mainly West Coast racers) still run this class. Serpent still produces a 235mm car (the 835) but it is mostly sold in Europe (the class is dead in the states). I have a Super Nitro and two Serpent 235mm Impacts (2wd) and loved this class and am sad that it died off. The Impact was more stable than a 200mm and with the right engine, almost as fast as an 1/8th scale on-road car but at a slightly lesser cost.
