Designed for the HPI Baja 5B, 5T and 5B 2.0, this big-bore engine modification kit allows you to convert your current engine into a 30.5cc performance monster. The modifications increase engine power up to an estimated engine power output of 3.75HP!
Inside each kit you will find a large 36mm cylinder, matching 36mm piston, 30mm stroker crankshaft, piston ring, wrist pin, insulator gasket, new spark plug, and other small hardware for installation. The modification kit also fits the Zenoah G23LH, G230RC, G260RC and Chung Yang CY23RC, CY26RC, CY27RC, CY29RC, and GP290 engines.
NOTE: This high-performance product requires 91 octane (using the R+M/2 octane rating method) or higher octane fuel, and due to the nature of this modification, the kit comes without warranty from the engine component maker.
