that depends on "significant increase in power" and how you define it. How fast you want your car to go.
If you needed alot of power, you could pay someone to fab up a turbo system for your car. Spend several grand to increase your power up 30-50% or so. And then watch your engine blow itself to pieces prematurely.
Or, as Andrews suggested, you could go buy a car that has the power that you desire pre-engineered into it.
The Versa is never going to be a terror. You can spend some money and get SOME improvement in performance without major impact to its drivability or reliability, but to give it gobs of power... it'll be expensive, and may not last long.
