John E came to Z Car Garage through a dealership connection at Dublin Infiniti. He purchased this Q50S Red Sport in 2019 with 46k miles on the odometer and it was time for bolt-on performance upgrades with dyno tuning.
We installed several parts from AMS Performance including their AMS Heat Exchanger, AMS Coolant expansion tank. Helping the VR30DDT engine breathe are AMS downpipes and a full Fast Intentions cat-back exhaust system. Photos of each are shown below.
The new AMS heat exchanger compared to the stock unit and installation:
AMS expansion tank installed replacing two plastic OEM units:

The Fast Intentions cat-back exhaust replaces the restrictive OEM system:
Standard exhaust tips on the FI exhaust system, we love the quality, fitment and sound of these parts:
We also installed new Hotchkis sway bars front/rear. Stock vs new below:
Dyno Tuning
Straight from the factory, the VR30DDTT is an impressive motor rate at 400 hp and 350 ft-lbs tq stock. It is actually underrated as we have seen with dyno testing. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Rob tuned John’s Q50 using EcuTek, making 404hp/435tq at the wheels. A significant improvement over the 336hp/338tq baseline:

Enjoy The Boost John!
