I am guessing you are from Canada.

Minor gain from stock.
5-10whp with bolt ons.

Swap or Turbo is the way to go.

CivicsRdBest is a glorious beacon of light

Don't expect much hp. The 1.7L engine is very effecient and was tuned fairly well from the factory.

basically, by the time you spend enough money to make the 1.7 liter go fast, you would have spend way more than a engine swap
