This is a direct replacement for the discontinued GTII 7460 FULL TURBINE KIT (11003-AN012).

New from HKS, the 11003-AN018 GT Turbine Kit! This kit includes all of the necessary components for an effective and powerful upgrade on your S14/S15 SR20. The highly reputed kit was redesigned with the newly designed GTIII RS turbine with a greater advantage under high speed range.

The same cast manifold included in the GTIII RS kit is also included. It is much more durable than a stainless steel manifold. Cast manifolds are not only durable but also very reliable. Port's shape and pipe junction are designed to reduce primary exhaust pressure. Turbine is installed on the manifold and improves engine compartment appearance.

For SR users, Front Pipe is the important factor to decide road clearance.The extension layout was designed to be connected with current Front Pipe (triangle flange). The extension has two bosses so that A/F knock sensor can be installed as well as the stock O2 sensor. The bypass pipe is atmospheric exposure type that makes external wastegate sound. Modification is required in case return connection is needed.

Kit includes:

• Highly durable cast exhaust manifold.
• HKS special wastegate to ensure stable boost control.(68.9kps)
• Wastegate return to stainless steel in consideration of environmental pollution.
