From Nissan 350Z & 370Z Wiki
This year, HKS is celebrating 35 years of building the finest automotive performance equipment in the world. Following the release of the GT Supercharger, HKS has developed the GT Turbo Set up kit for the popular Nissan 350Z equipped with the VQ35DE engine. HKS set up kits provide the customer with the basic foundation of parts to build their own complete, custom turbocharger kits. The twin turbo set up kit is offered in 3 different turbine configurations allowing customers the ability to choose from quick response to high horsepower applications. HKS GT Set up kits include: cast exhaust manifolds, HKS GT Ball-bearing turbochargers, exhaust extensions, chamber pipes, high capacity oil pan, actuators and brackets.

Special Turbo Systems
GT3037 Single & GT-ZZ Twin
The Special Turbo System is an after-installation turbo system designed to achieve +100ps power with the normal Z33 equipped with an NA engine. Two types of Special Turbo Systems are available including the "GT3037 Single" specification, which provides a true turbo car like feeling that emphasizes the stretch in the medium and high speed ranges, and the "GT-ZZ Twin" specification, which features the characteristics of ease of use with flat torque properties from the low speed range to the top end. In consideration of environmental aspects, both kits feature an HKS metal catalyzer (with exhaust gas heat certificates issued by a 3rd party) as standard equipment. The kits offer a considerable solid ride, improved environmental performance, and new power tuning options. When used in conjunction with the HKS forged piston kit and reinforced connecting rods to further boost up performance, the performance of the turbine itself can be exhibited of an even greater level.
Speculation
No official information has made it to the US so far. However we can speculate based on the pictures, HKS history, and their target market. HKS USA will be doing testing to confirm the system will work for the US market left hand drive cars.
- Turbos
- The twin turbo kit utilizes twin HKS GT-ZZ turbos.
- The single turbo kit utilizes a HKS GT3037 turbo.
- Engine Management
- Most likely we will see the HKS F-CON SZ engine management system. This is the same EMU that is used in their Rotrex supercharger kit. The major downside to this EMU, is that a certified HKS Pro dealer is required to tune the system. The dealers are few and far between and tuning may turn out more costly than with a more common EMU.
- Blow Off Valve
- Expect a simple bypass valve to be included in the production kit to keep costs down. Rarely is the best of all components included in a turbo system. The standard bypass valve is also used in their Rotrex SC kit.
- Fuel System
- Their supercharger system was designed with CARB certification in mind limiting them to addon fuel injectors. However, I dont believe HKS will be going that route with their twin turbo system and will be including a fuel pump and six injectors at minimum. A return fuel system would be an added bonus, but there is no evidence of this either way.
- Manifolds
- From the pictures it is clear these are mandrel bent stainless steel and not cast. Hopefully HKS does not experience the same cracking problems the Power Enterprise TT manfolds had. Also, at this time we do not know the progress of the kit, an everything may still be in prototype form.
- Filters
- Judging from the placement of the 1 visible filter, expect dual Super Mega Flow air filters taking care of the breathing on this kit.
- Catalytic Convertors
- The sign at Tokyo Auto Salon 2006 that HKS was displaying said both the HKS Twin Turbo Kit and HKS Single Turbo kit will come with HKS high flow metal catalytic convertors. These can be seen in the pictures below. It is also noted that the catalyzers are 3rd party approved.
