Originally introduced in November 2002 this crankshaft was a factory-fit component on all Japanese Domestic Model vehicles. For many years the crankshaft was supplied balanced, cross-drilled, and finished with a nitride hardening offering good potential as a budget tuning component. In 2013 the crankshaft was superceeded and both the cross drilling and nitride hardening ceased to be included in the manufacture, instead being replaced with a more cost-effective form of heat treatment.

This “JDM” crankshaft is still considered to be the best “standard” option available for all EJ20 engines and is the preferred choice before investing in more expensive billet crankshafts.
