Setting Records: RZ34 Z First 9-Second Pass

The RZ34 Z is the newest offering in the Nissan Z line, and AMS Performance was quick to set a world-first 9-second pass using (by today's standards) relatively basic upgrades.

Back in 2022 9.92 at 137mph was the first run in the 9's in a RZ34 Z 2023 Nissan Z Proto Spec, and Nick Cassara of AMS Performance gives us some insight into the similarities and differences of this new platform compared to Infinity Q50 and Q60 models when it comes to the 3l V6 twin turbo VR30DDTT engine, and Nissan 370z on the chassis front.

The car is running upgrading turbocharges, a bigger DI fueling system, drag slicks and not much else to make 719hp with the aid of EcuTeks reflash tuning software capabilities. The biggest issue to overcome with this platform, party due to its very compact packaging, is heat soak and cooling complications making it the first port of call for any owner looking to make more power with aftermarket mods and tuning.

Modifications include:
– AMS Intakes (Prototype)
– AMS Heat Exchanger (Prototype)
– AMS Full Exhaust incl. Downturns
– AMS VR30 Intercoolers
– AMS Flex Fuel Kit (Prototype)
– AMS RA405 High Pressure Fuel Pump
– AMS Low Pressure Fuel Pump
– AMS Inline Fuel Filter
– AMS Fuel Pressure Sensor
– AMS Stage 2 VR30 Injectors (Prototype)
– Pure Turbos (Current gen/”Stage 2″ from Infiniti Q)
– Coil-overs and Misc. SPL Suspension Links
– Hoosier 28″ D06 Tires
– AMS e85 Flex Fuel Tune
