2.7L 95mm Stroker Kit for BMW E30 M3 S14

Custom CP Pistons + Carrillo Connecting Rods + Billet 4340 Crankshaft Combo for BMW E30 M3 S14 2.7L Our intention with our S14 stroker kit was to design a no compromise solution to increase stroke as much as possible in the OEM 2.3 liter block. We are now on our third iteration of this bottom end design. Our crankshaft is specifically designed by us for maximum clearance on the oil pump and block. We were unwilling to make compromises in rod length and as such this required that we design a custom rod for this application. Our rod is longer than the 2.5 liter EVO rod. Naturally this is difficult to accomplish when increasing stroke 8mm. We work with CP Pistons to design a custom piston that has the minimum safe compression height while still utilizing a 3 piston ring package and avoiding an oil support ring. While rod ratio is decreased over stock we are at the maximum rod length achievable which will decrease side loading of the piston compared to other stroker solutions on the market
