NISSAN SR20DET

We challenged the limits of stock bodies in drag racing. Even though it has just 4 cylinders, the Silvia with SR20DET engine boasts more than 700 ps. The durability which bears the time trial exceeding 100 times was proved. 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.
