wat engine wil fit in my civic dx it has a 1.35 in at the minute im wanting to put something bigger in it without to more trouble.

 

You can fit a lot of Honda engines in your civic. What are you looking for? Gas mileage? A lot of power? Some power and pretty good gas mileage?

What year is your Civic? Is it the original engine?
And what do you mean you have a 1.35L? I've never heard of such a thing coming in a Civic.
