The R&D 1600cc Engine Kit for the SX-R was developed specifically for the UIM Racing Series where “Big Bore” Kits are allowed in the N.A. classes. R&D starts with an OEM Cylinder Block and precision bores the block to 85mm replates the bore (rechromes), and finish hones to specification. R&D has worked with CP exclusively to develop Forged 85mm Racing Piston Kits. R&D offers high quality forged aluminum, heat treated, and CNC machined racing pistons in 12.5-1, 13.5-1. Forged and CNC Machined pistons in High Performance marine applications are a must. Trust the pros at R&D with all your compression ratio, boost, and engine management needs or questions.
