Greddy 11520097 T517Z Twin Turbo Kit for Nissan 370Z Z34 8cm RHD

The GReddy 11520097 is a bolt-on twin turbo kit engineered specifically for the Nissan 370Z (Z34) platform, featuring dual T517Z turbines with an 8cm² turbine housing. This complete kit delivers a significant power upgrade while retaining compatibility with the factory catalytic converter, making it a compelling choice for performance enthusiasts seeking serious forced induction.

The kit is designed for use with a stock engine using the included boost restrictor, limiting boost to 0.6 kg/cm² for a conservative, reliable setup. For those who upgrade to forged pistons and a strengthened engine, removing the restrictor allows boost levels up to 0.8 kg/cm², capable of achieving output exceeding 500 PS.

Key Features:

• Bolt-on T517Z twin turbo fitment for the 370Z (Z34) VQ37VHR engine
• Exhaust manifold and turbine outlets constructed from 4mm thick stainless steel lost-wax castings for superior crack resistance and durability
• Dual independent left and right intercoolers (TYPE16 twin) for balanced intake air distribution across both cylinder banks
• Includes boost restrictor for stock-engine compatibility at 0.6 kg/cm² boost
• Compatible with the factory catalytic converter — maintains vehicle inspection compliance
• Compression tubes: aluminum 50φ–70φ; suction tube: aluminum 60φ
