The BC stroker kit for the Nissan VR38DETT engine incorporates a 94.4mm stroke, steel billet crankshaft. Depending on bore size that you decide, the BC kit will take you up to a 4.45L with a safe 100mm bore. The VR38 kit utilizes premium steel billet connecting rods. As usual, each BC kit features custom CP or JE pistons, wrist pins, and full ring pack. Big time horsepower and torque gains.
BC 4340 billet steel crankshaft (94.4mm stroke).
BC 4340 Pro Series I Beam connecting rods w/top-of-the-line ARP Custom Age 625+ bolts.
CP or JE aluminum forged pistons (any bore size, any compression ratio).
Upgraded 9310 Series tool steel wrists pins come standard.
Ductile iron plasma top rings, tapered second ring, low tension oil rings.
BC crankshafts are made from the finest, aerospace grade 4340 steel billet material. CNC machined on state of the art, 5 axis Mazak Integrex 300-IV CNC machines to exacting tolerances (.0001"). Every crankshaft features large radius journals that add rigidity for high horsepower, high boost, high rpm applications. Gun drilled, CNC ground oil holes feature a smooth surface for extra oiling, tear dropped for added oil scoop, cross drilled for priority main feeding to the rods and micro polished to a mirror finish for optimum bearing lubricity. All cranks are stress relieved, shot peened, magna flux inspected and nitrided (multi step heat treatment) for ultimate performance. Fully profiled counterweights are designed for reduced windage through the crankcase creating less oil resistance for better rpm potential.
BC connecting rods are CNC machined from aerospace grade 4340 steel billet, available in your choice of the European influenced H beam or the traditional I beam design (certain applications). All rods feature a deep, double ribbed cap that keeps the big end housing bore true at extended rpm and insures uniform bearing crush, delivering proper clearances for superior oil supply and maximum load carrying capacity. H Beam rods feature a deep radial groove pin bushing and oil holes at 5 and 7 o'clock (the beam acts as a trough), bringing critical lubrication to the critical wrist pin area. I Beam rods feature a oil hole at the 12 o'clock position that keep the pin end bore true at high boost. Available in your choice of ARP2000 fasteners (rated to 210,000 psi) or the ultimate faster, ARP's Custom Age 625+ (rated to 280,000 psi).
