JTuned Nissan 420Z TT: A 760 HP Twin-Turbo 350Z

Table of Contents show

Alex Yao has created a masterpiece, and her name is Alyssa. A stock Nissan 350Z is akin to a Yugo in comparison to this beast. I know comparing a 350Z to a Yugo is blasphemy, but when you see what this man has done to his car, you will agree. No, this isn’t a simple turbo upgrade to a mere 380 horsepower; Alex has started with an upgrade from the stock 3.5-L V6 to a monster 4.24-L GT Motorsports Stroker Kit.

That’s not all. He slapped on two Garrett turbos tuned to 18 psi of boost. That combo would be plenty for most people, but not Alex. Along with his other modifications (listed below), the Nissan 420Z pushes out a total of 760 RWHP and 713 ft-lbs of torque. The list of modifications includes a fully custom exhaust, suspension, brakes, and plenty of carbon fiber all around.

The Z rolls on beautiful 19? Volk GT-S Titanium Gunmetal wheels wrapped in Toyo T-1Rs have a completely new interior, barely resembling a stock 350Z. What’s Alex’s favorite part of the car? The custom “420Z TT” Rear Emblem, of all things.

The extensive list of modifications is below the photos:
