The 4B11 is the engine that powers the last of the legendary and iconic Mitsubishi Evolution series. The Evo X is widely used in circuit and street applications, and so, we have developed a 2.2L stroker kit to give this combination the increased capacity that it needs without sacrificing the ability to rev as required.

The kit consists of Nitto/CP pistons in either 86.5mm/+0.020" or 87mm/+0.040", cut from the Turbo HD forging, PVD Turbo ring set for the ultimate sealing capabilities and, of course, the CP 9310 wrist pins. Nitto 4340 143.75mm I-beam and H-beam connecting rods are both available for the stroker kits and come with ARP 2000 rod bolts as standard. The option to purchase Custom Age 625 rod bolts is also available on purchase. Finally, the Nitto 4B11 2.2L 4340 stroker crank is also included in the kit.
