Would these be good mods to start with?

On one side is what is affectionately called the “demon bolt” that is difficult to reach and remove. On top of that, the cats are what will give the most trouble emissions wise

After headers or high flow cats or test pipes, you run into a wall. You can get cams, ported manifolds, upgrade the fuel system, and aggressively tune, but that phase is VERY expensive and still wont result in much gain. I think even the most extensive builds have struggled to approach 400 wheel HP.

If power is your goal, forced induction is probably the better choice

I personally go with upgrading the clutch and flywheel. This doubles as a maintenance move since our cars have a clutch slave cylinder notorious for failure. Swapping in an upgraded unit from Z1 or zspeed while also grading the clutch and adding lighter flywheel will make a big difference; our stock units are heavy Af. You will notice an immediate improvement in revability and not worry about the slave cyl failing

After that, turn your money and time toward the suspension and brakes, and appropriate cooling

As much as I would love to go forced induction, I don't think that's something I'll be able to do anytime soon, but definitely a goal of mine one day. Suspension is another thing I've been trying to learn about as well, thinking coilovers are what I would get when I figure out what would be a good fit for me.

Sorry if it sounds like I don't know what I'm doing lol, I'm trying to learn as much as possible but work doesn't give me much time these days. Thanks for for all the input!

In addition I installed a Sprint Booster, which I found more useful than the tune. But my best upgrade was having Sparco racing seats installed (no sliders, so sit even lower). The racing seats make me feel that I'm in a performance car and not just driving a fast sporty coupe. Yes, I can take turns faster now, but the feel of sitting in racing seats makes a big difference. Racing seats make the 370Z look cool on the inside too. I'm 6'2" and it's not difficult getting in and out of the seat. The motion of my body getting in and out of racing seats actually enhancing the driving experience. With the 370Z stock seats getting in the car felt similar to getting in my SUV or other sedan. With the racing seats my 370Z really feels very different from ordinary appliance blob cars.
