Description

NITTO’s 4G63 2.2L Stroker kits consist of an increased stroke crankshaft made from 4340 forged billet steel, 4340 forged billet connecting rods and unique JE/Nitto forged piston set along with upgraded thick wall gudgeon pins and premium ring sets. Engine capacity is increased from 2.0ltr to 2.2ltr which provides more power and torque throughout the RPM range. The 94mm stroke / longer rod 2.2L combination is commonly a popular choice for use in time attack and circuit vehicles due to its calculated rod ratio which leads to a more RPM happy engine. All components have been meticulously machined to exacting tolerances and the highest standards. All Nitto stroker kits are far superior to the cheaper manufactured kits currently available that consist of cast forged crankshafts without proper counter weight design and high silicone content pistons.

NITTO’s 4G63 2.2L Stroker kits are designed for use in all motorsport classifications including drag racing, and circuit racing. Rotational capability is lifted to 10,000+ RPM and power handling is rated to 1100 HP *. The changed harmonics due to the crankshaft material and design results in a much “freer revving” more balanced engine.

Continuous testing and development has allowed us to design a kit with extreme strength whilst retaining a sensible reciprocating mass weight.

Available in 2 configurations with H-beam or I-beam connecting rods.
