We have built many BD series of engines over the years most of which have been for RS200 competition cars. We can offer any state of tune for Road-Rally-RallyX-Hillclimb. Starting with Pat Doran’s Rallycross engine we have converted it to use a modern style piston as in our YB engines and using a multi butterfly inlet system to improve response while not compromising high end horsepower. The inlet manifold features the original magnesium plenum cover to keep some originality in the build. We keep good stocks of RS 200 engine components please call or visit our online shop.
