Full billet 4340 Nitrided and Balanced Crankshaft
Note: The standard RB26 capacity is 2568cc
Using the 79mm stroker crank, std length conrods and custom pistons, the displacement is increased as follows:
86.5mm bore and the 79mm stroker crank = 2750cc / 217cc increase
87mm bore and the 79mm stroker crank = 2818cc / 250cc increase
With the increased cubic capacity from the 79mm stroker crank, big increases in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
CP pistons come with rings, pins and locks. The gudgeon pins are upgraded to 9310 hardened alloy steel with 4.5mm wall thickness.
Note: Clearancing of the cylinder block is sometimes required.
