hey what is the fuel tank on my 93 sedan and what kind of mpg can i expect with my d15b7 (headers and muffler) with 5speed please help i'm moving 1200 miles this weekend and need to know how much gas i'll need

you have a 12 gallon tank
and i would expect atleast 35 mpgs on the highway
sooo roughly your going to need three full tanks of gas
