Features:
- Factory Replacement Type Sports Turbine Kit for SUBARU EJ25 Single Scroll Turbine.
- 360HP was the number we figured out as the practical maximum engine output of the stock EJ25 engine from various verification. To reach the optimized performance within this range, the turbine kit was developed. For further performance improvement, this turbine kit can be used with the upgraded pistons and connecting rods; so the engine output can be reached to 430hp.
- 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 restricting 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 buy separately depending on type of the boost pressure controller.)
- This kit can be used with any HKS product.
