The Honda B series engine is still very popular around the world with lots of fans. Since the majority of these engines are of high mileage, customers can be concerned about its condition. Toda Racing has developed an overhaul (O/H) piston kit specifically for such engines. Designed with a longer skirt compared to our standard high comp piston and an only mild increase in compression ratio over the stock Honda. This makes it more of a straight swap overhaul piston compared to most aftermarket pistons.
