SUBARU EJ20

JUN participated in the New Zealand maximum high-speed challenge by JUN SUPER IMPREZA GC8, and achieved over 300km. Moreover, good results were recorded in the circuit of each place. The degree of technique of EJ20 engine tuning has been proved. In order to induce those results, we performed original engine processing and repeated the test. We feed back such technology to a user and high quality engine processing is offered by JUN.

We receive a customer's cylinder head and perform high quality processing to a cylinder head. It is also possible to build a JUN parts into the cylinder head which processed as a short head assembly. Moreover, we can make cylinder head in the specification for which you wish. We prepared two menus, menu1 and menu2.
