Intercooler upgrade before adding more power?

NorthEnthusiast44Community StarterApr 6, 20262023 Nissan Z PerformanceNYC / Long Island
2023 Nissan Z Performance, about 22,000 miles. On repeated pulls I can feel the car soften as temperatures rise. Would you prioritize an intercooler before adding more boost, even if the current setup is otherwise stock? I'm in NYC / Long Island.

Thanks — that narrowed it. I'm going to try the simpler check on the 2023 Nissan Z first. If the story changes I'll post the new data.

Write down what you already tried. A second data point from another 2023 Nissan Z owner helps more than a generic diagnosis. I'd do that before spending real money. Take it or leave it — that's what I'd do. Not trying to scare you — just skip the expensive first guess. Might be overthinking it, but I'd rather overthink than overspend.

Don't overfit one forum story to your car. If it still isn't clear on the 2023 Nissan Z, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. I'd want that in writing, not as a promise. I'm keeping receipts and dates in one folder.

Owner notes beat generic advice here. On the 2023 Nissan Z in NYC / Long Island, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “intercooler upgrade before adding more power,” that was the fork that mattered for me. Parts cannon is a personality type I try to avoid. I'd rather look cautious in this thread than stuck later.

Quick add on that: A second data point from another 2023 Nissan Z owner helps more than a generic diagnosis. I'd do that before spending real money. I'd want a dollar figure or a measured spec, not 'should be fine.' Not trying to scare you — just skip the expensive first guess. If this is nothing, great. I want that in data.

Not convinced that's the whole story. Verify the cheap/easy branch on the 2023 Nissan Z before a big repair or a big spend. I'd do that before spending real money. Not gospel, but it saved me a headache. I've seen both outcomes, which is why I'd test instead of assume. This is me being the wet blanket on purpose.

I'd keep this practical. Verify the cheap/easy branch on the 2023 Nissan Z before a big repair or a big spend. I'd do that before spending real money. Monthly payment math is how wallets disappear. Doing the boring step first on purpose.
