New Design GTII 7460

Highly-reputed GT2835R kit was redesigned to the kit with newly designed GTII 7460 turbine.
New kit has more advantages under high speed range and maintain handiness like GT2835R.

Cast Manifold

The same cast manifold included in the GT2835R/GT3037S kit is also included. It is much more durable than stainless steel manifold. Cast manifold is 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; it improve engine compartment appearance.

Connection to stock Front Pipe layout. Atmospheric exposure type external wastegate

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.


Even though the turbine was upgraded to latest design GTII 7460, the MSRP stays the same so that it can be affordable for more silvia owners.
