I feel very much the same. One of my first cars was a ’72 240Z, back in 1978. At 16, I was the talk of my peer group—it was something special. A couple of years later, I had another ’72, but as life progressed, practicality took over and I could only manage one vehicle.
Like you, I found the Z...

Hi all, thanks for your comments. Very helpful.
I'm going with your recommendations and adding a heat exchanger to the pkg. Going with AMS.
Tuner agrees that catback likely only add 10%, and i want to retain factory sound, so leaving for now. Though I am open to systems that improve exhaust...
You are correct. I looked deeper, and the Wheel HP/TQ numbers would be less on 91/93 pump gas. Overall, it's looking like my pkg would amount to about 90-100 hp and 150 tq gain.
As per ChatGPT:
Stock is an official factory crank rating for the 2024 Z NISMO. 91 and 93 octane figures are...
Thanks. Funny. I almost went with Mishimoto intercoolers, but read they didn't cool as well as AMS on repeated pulls. Though, I admit that I liked the the idea of AMS continuity in my package.
P.s. I watched the Mishimoto intercooler Z installation video...impressive kit.
Nice! I see that they charge $5k USD for pkg only on website. I guess I am going with my version of a pump gas version - 91/93 Octane (hence no fuel delivery related components), and intercoolers rather than heat exchanger, with full catted downpipes instead of lowers only. Being a new car I am...
It maybe. However I reran Chat with OEM Performance/Nismo exhaust and talked with my local tuner - the 5-10hp gain estimate holds. Where the big difference would be in applications with upgraded turbos with substantial airflow increases and output targets well above 500 hp.
WHEN CAT-BACK...
Hi all,
Here is an ChatGPT summary of my final decision on upgrades:
Redoing it properly:
For a 2024 Nissan Z NISMO, Nissan rates the car at 420 hp and 384 lb-ft at the crank from the factory. In wheel terms, a stock NISMO typically lands well below that on a dyno because of drivetrain loss...
Very helpful info thanks. Almost 3/4 of an inch for both front and back. Wondering if anyone has actually tried that or other wider set ups on stock suspension and camber?
Sorry, no pic of wheels on my car, but considering these
