How does turboing a motor effect fuel economy. I know it will decrease do to increased fuel flow, but how significant is it. I realize there are lots of variables here, but what is a ballpark. I want to run 450's with afc on my d16y7 at about 10 psi. WIll mileage go down a ton over stock. Also, is premium, high octane fuel a must if managed well. Thanks.

 

Your MPG will now be dictated by your right foot.
I can get a low of 170m per tank and a high of 320.

 

Actually.. driving in the city, if not really pushing it - my mileage increased after installing turbo. It's prolly due to earlier shifting now, since car really pulls nice at low rpm (advantages of smaller turbo).

 

95ex d16z6: I get between 180 - 285 mi on a full tank. I can get 300 if I do a highway trip.

not that bad if you think of it anyone know how much u get with stock car ? so i can compare it ?

 

stock civics and crx's get anywhere from 35 - 45 mpg some even a little more if its a well set up hf. anyways with an 11 gal tank or so and lets say 35mpg the avg civic mileage.. youd get around 380 miles to the tank or so.

 

It depends on your setup, and your results will vary even then. With my EX sedan, I average about 33 mpg NA.

 

Thats not too bad of a loss for a turbo. I have gotten as much as 38 on the road with my dx sedan, but around town it drops to like 26. I dont even hammer on it or anything, you just gotta give it a lot to go at all. No power, hense my need for a turbo. Thanks for your input guys.
