This crank is designed for 2500+whp! Features Honda journal for aluminum rod clearance. 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. \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff2a00;\"\u003eVehicle Fitment:\u003c\/span\u003e \u003cbr\u003e1987-1998 Toyota Supra \u003cbr\u003e(MK3 and MK4 with 2JZ engine) \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff2a00;\"\u003ePurchase Includes:\u003c\/span\u003e \u003cbr\u003e(1) EN40 Billet Crankshaft \u003cbr\u003e\u003c\/p\u003e\n\u003cdiv style=\"overflow-x: auto;\"\u003e\n\u003ctable cellspacing=\"0\" cellpadding=\"0\" border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr bgcolor=\"2d2d2d\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003ePart Number:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eApplication:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eCrankshaft Stroke:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eRod Journal:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eMain Journal:\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eWeight:\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"404040\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eBC5308-90\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e2JZ Toyota Supra\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e90mm\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e45mm Honda Journal\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e62mm\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e59.7 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr bgcolor=\"505050\"\u003e\n\u003ctd style=\"color: #ffffff;\"\u003eBC5308LW-90\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e2JZ Toyota Supra\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e90mm\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e45mm Honda Journal\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e62mm\u003c\/td\u003e\n\u003ctd style=\"color: #ffffff;\"\u003e48 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff2a00;\"\u003eNotes:\u003c\/span\u003e \u003cbr\u003eImages are for reference \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff2a00;\"\u003eMore Info:\u003c\/span\u003e \u003cbr\u003eBC crankshafts are crafted from aerospace-grade 4340 steel billet and EN40 steel alloy for power levels exceeding 2500+whp. They are CNC machined on advanced 5-axis Mazak Integrex 300-IV machines to precise tolerances of .0001\". Each crankshaft features large radius journals for added rigidity in high horsepower, high boost, and high RPM applications. Gun-drilled and CNC-ground oil holes provide a smooth surface for enhanced oiling, with tear-dropped designs for added oil scoop, cross-drilling for priority main feeding to the rods, and micro-polishing for optimal bearing lubricity. All cranks undergo stress relief, shot peening, magnaflux inspection, and nitriding (a multi-step heat treatment) for peak performance. Fully profiled counterweights are designed to reduce windage through the crankcase, decreasing oil resistance for better RPM potential. BC also offers a Micro Polish finish that improves oil shedding, reduces oil foaming and parasitic losses, and enhances ion nitriding, increasing overall tensile strength by 10% compared to standard BC crankshafts.\u003c\/p\u003e\n\u003ca href=\"https:\/\/stmtuned.com\/collections\/bc-brian-crower-products\" style=\"color: #afafaf;\"\u003e\u003cbr\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cspan style=\"font-size: .8em;\"\u003e See more BC Products\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/a\u003e","brand":"BC Brian Crower","offers":[{"title":"Standard","offer_id":50560587104598,"sku":"BC-BC5309-86","price":5518.66,"currency_code":"EUR","in_stock":true},{"title":"Lightweight","offer_id":50560587137366,"sku":"BC-BC5309LW-86","price":5966.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/9531\/8102\/files\/bc-brian-crower-en40-billet-crankshaft-2jz-toyota-supra-bc5308-90.jpg?v=1749194201","url":"https:\/\/www.speed-addicts.com\/en\/products\/bc-brian-crower-en40-billet-crankshaft-2jz-toyota-supra-bc5308-90","provider":"Speed Addicts","version":"1.0","type":"link"}
