Is it a coupe or hatchback? If it's a coupe, they're known as EJ8 and if it's a hatch, it's a EJ6.

They are alot of displacement motors for a GOOD DD, with awesome mpg. Cheapest thats reliable is a d16y8, 1.6 VTEC, not too fast, but it'll get you close to 35 to 40 MPG. If you want something alittle faster, a b16a2 would be a good swap, quick, good gas mileage.

If it's your first honda, it'll be easy as hell to work on, to be honest lol. They're like legos.
