#107072, "I want a turbo that won't kill my fuel economy"
I am thinking of turboing my 420a but I like the fuel milage I get and don't want to ruin that. What turbos would be good candidates to increase or at least not drastically reduce my milage? Thanks.

With a turbo, fuel economy is entirely within the control of your right foot. If you choose the turbine correctly, the restriction on the exhaust will be minimal. If you keep the engine out of boost, you can keep the A/F lean and retain your mileage. When you put your foot down and get into boost, your A/F will have to be richer and mileage will drop as your power increases (that relationship is unavoidable). I have kept a log of every gallon of gas that has been put in my car for the past twelve years. If I avoid tanks where I was tuning or screwing around, my average mixed city/highway mileage is essentially the same. That covers bone stock to NA bolt-on to turbo bolt-on to fully built w/ turbo. When I am tuning or screwing around, my mileage drops like a stone. It is within your control. There is on automatic penalty for adding a turbo.

Your smiles to the gallon must be through the roof.
To the OP. Good gas mileage with a turbo is more dependant on your right foot than the turbo size. With My WRX I could get 30mpg or I could get 17mpg. For good mileage I just had to keep my right foot light and upshift BEFORE the turbo spooled up.
Hell, I've gotten horrible mileage with my NA 420a Eclipse, it was around 13mpg IIRC, but I was having a shit ton of fun at the local track (road course). I even managed to setup some clean passes on cars that I shouldn't have been able to pass that day It was a good way to waste a tank in half a day.

Your right, All those hot houston nights, im currently building a hideaway license plate out of two antenna actuators. The truth is its not what you drive its how you drive, a prius only gets 16mpg at WOT, thats something to think about.
Why did i turbo a 420a? Why is your 4g63 smoking in a ditch?

Agreed my buddys Ram hemi only gets 7mpg but he drives it like he stole it. I just recently got 30mpg on a tank on my 98 NA talon but I was grandma driving it.
