NA motors are expensive to mod for marginal gains of any meaning. A turbo based motors yields much more power when mods are done in general. None of it is cheap. My Abarth 500 here in Germany has 135 hp with my G-Tech ECU mod for about 700Euros its how above 163 with a nice boost in torque. A bigger turbo/ ECU and exhaust will get you about 210. Thats about 4000euro package from G-Tech overall for a healthy boost to 210. More could be found but the gearbox limitations begin to arise as well.
Again not cheap but turbo based motors respond better and give you more flexibility. You live with what you are given.
I am no expert just passing what Ive seen in general.
