Nissan CA18DET 87.6mm Billet 4340 Stroker Crankshaft
This is a true billet crankshaft machined from Billet 4340 core stock (not a cast forging blank that is final machined).
Each crank is machined from core stock 4340 on a CNC machine, then Nitrided and final ground.
With the increased cubic capacity from the 87.6mm m 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.
The CA18DET engine in its factory form has a 83mm bore and 83.6mm stroke, giving a displacement of 1809cc.
Using the 87.6 mm stroker crank, std length conrods and custom pistons, the displacement is increased as follows:
- 83.5mm bore and the 87.6mm stroker crank = 1919cc / 110cc increase
- 84 mm bore and the 87.6 mm stroker crank = 1942cc / 133cc increase
