Mitsubishi 4G63 94mm 4340 Stroker Crankshaft
With the increased cubic capacity from the 94mm stroker crank, 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.
Full Forged 4340 - Nitrided, Balanced and Full Counter Weight Crankshaft
The 4G63 engine in its factory form has a 85mm bore and 88mm stroke, giving a displacement of 1997cc.
Using the 94mm stroker crank, standard length conrods and custom pistons, the displacement is increased as follows:
- 85.5 mm bore and the 94 mm stroker crank = 2159cc / 162cc increase
- 86 mm bore and the 94 mm stroker crank = 2184cc / 187cc increase
Note: If conrod to block interference occurs, slight clearancing may be required.
