BC offers stock bore XPTurbo cylinder jugs that have been hopped up with copper o-rings and .500" dowels that mate to the cylinder head to keep both from shifting at high boost levels. We choose the XPT cylinders because of the closed deck design and the fact that they're +.050" taller deck height. This adds rigidity and support to the cylinders as well as delivering less piston side loading with an optimal compression height design piston. BC also offers a +1mm overbore (94mm) that has been...

RZR XP1000 and XPT motors are notorious for excessive crank case pressure, the factory breather system recirculates crank case blow by back into the intake system from a breather box on the lower front side of the engine case.   The main problem with this design is how close the breather box is to the oil pan allowing oil to be carried out with the crankcase blow by and then put into your intake charge and burned. XPT models are known for rod bearing failures due a number of issues, one bein...

These exclusive mains from King Bearing however do provide the proper oiling from the mains to the rods with some qualified machining. King XP line bearings are a hardened coated race bearing vs the OE soft Babbitt bearing. To thoroughly “bulletproof” the case, we designed an oversize O.D. (1.75...
