Outside of regular oil changes, I’d say spark plugs at 75-90k. I would flush coolant at 100k, then every 60k. Check your belts and hoses at 95-110k. Check your brake and fuel lines at 100k. Air filter every other oil change. If you ever take your intercooler off, check for oil blow by. A little bit won’t kill it. If at or under a quarter tank, don’t go full throttle to reduce strain on the fuel pump.
Transmission fluid flush at 90-100k with the filter. At 75k is when I would make it a habit to check oil every time at the gas pump if you think of it. Modern cars can burn oil per spec at higher mileages.
The turbo should be fine if you keep your oil and coolant maintained. If you just use it as a daily driver, you shouldn’t need to touch anything else until it breaks. An upgraded fuel pump can be insurance, but not necessary.
At higher mileages (120k+), you might start seeing signs of worn suspension and worn bushings. But if they aren’t wobbling and aren’t broken and you don’t mind the ride, it’ll be fine. But replacing bushings would make the ride good as new
