I don't plan to have more than 250bhp. I will track the car (lightly, no racing tires and suspension), so the config must be reliable under beating. What is the best way to achieve this goal?

Think the biggest factor would be what is your current budget? And or future budget?
From the sound of things you would be a good candidate for a lower boost supercharger setup could run 7-8psi at 240whp all day. However this route when everything is said and done probably 7.5k$ for kit, install, tune.
Or a ace header + custom tune setup for roughly 2.5k$ and about 200whp.
However neither option restricts you from the other and they both benefit eachother. U could sc now and add header or header back later or vice versa.
So depending on budget you may want to go header first, and if that is enough or getting close to enough power then u don’t need to invest in sc.
If committing to NA and not SC then a CAI if maf scaled and if no E85 then billet blocks.
A lot of ppl say ace 350, that is best daily driver low / mid range torque. If you want to stay rev happy and have some mid / top end power the ace 250 is a bit cheaper and offers more 4K+ then the 350 but doesn’t 100% eliminate torque dip.
And lastly like I mentioned earlier weight reduction. The first 100lbs or so is free/cheap and can make a huge difference. On stock car 100lbs is about 7.5bhp. From a ratio standpoint.
