We are proud to introduce our new line of Twin Turbo Kits for the 370Z based on the venerable Mitsubishi Heavy Industry turbocharger line up. These turbos are water cooled and oil lubricated journal bearing turbos with a great track record of reliability, performance and value. Available with our kits are three different turbo options: 16g (600hp), 18g (700hp), and 20g (900hp). All three turbo options cost the same. Since the VQ37VHR is such a great engine, the 16g and 18g options are great for stock motor builds while the 20g is the way to go for built engine, high horsepower setups.
Since this kit was designed to be as unobtrusive as possible, it is the only turbo kit that retains the factory crash bar. Also, there are no permanent modifications that have to be done to the car to install and run this kit successfully with outstanding performance. In addition, the engine can remain in the vehicle for installation.
As usual, we offer our kits in two basic forms: Turn-Key and Tuner. Our Turn-Key kits come with our GTM Spec ECU flash and upgraded fuel system components. These kits are designed to deliver a complete package that can be installed on a car and perform flawlessly out of the box. Our Tuner Kit, on the other hand is a complete kit that gives the end user the freedom to choose whatever engine management and fuel system components they prefer.
