Hello and welcome!

With enough money most things can achieved. What's your budget?

That's quite a nice budget.
Are you just looking for power? Or do you need to look at brakes and suspension as well? I ask because you may need to look to those places if you go too high with your power as you will want to go around corners and stop :)

In general terms you could open up more power by upgrading the air intake, exhaust, fast road cams and a remap. As a pure (albeit slightly educated) guess I'd say you'd push that 300 to 350.
Turbos are way to get big gains but that opens up a whole lot of other work and your €5k budget will disappear quickly.

If you arent going crazy your brakes etc will probably be ok.

Are you doing the work yourself or paying for a professional?
