Feature

Factory Replacement Type Sports Turbine Kit for SUBARU EJ20/25 Single Scroll Turbine.

Compared to the existing kit 11004-AF010, EJ20 engine is the main target of this kit; therefore, A/R of the exhaust housing is 0.67.

The ball bearing turbine of this kit was originally designed by HKS. Enlarged turbine wheel increases air volume. The ball bearing can reduce response loss. Also, the bypass port was also enlarged to reduce load to the engine and restrict the exhaust pressure increase at high engine rpm.

This turbine kit includes all necessary parts in order to install the kit such as an actuator, oil outlet pipe, etc. (There may be parts necessary to purchase separately, and parts modification is required in order to install this kit.)

Note

Since the turbine scroll is bigger, it comes in contact with the transmission case. Shave the part of transmission where comes in contact with the turbine.

Modification of factory heat insulator and bracket is required to install this kit.

This kit may be able to be installed on GC8 and GDB Type A & B with single scroll turbine. However, we did not test this kit on these models.
