Not a lot of older cars here I've noticed so I figured I'd post the general plans for my vehicles. Please post any other tips that I might have missed, getting EF numbers hasnt really been a priority until now.
1989 Ford Mustang 2.3L / 5speed
1989 Dodge Daytona 2.2L / 3speed auto
I hope to have two vehicles with 160HP that can easily tackle the mountains I live in. Balance fuel efficiency and performance
1)Major Tune-Up including replacing the O2 sensor. Now should I pay more to get the exact OEM set O2 sensor or go for a cheaper one?
2)Weight reduction I'll be removing everything in the vehicle that I do not currently use, I'm even going as far as removing the backseat from my Daytona. I'll try to find some ultra lightweight wheels as well at least half of the weight of my current ones.
3)Lowering the vehicle to help decrease wind resistance
Thats a pretty basic idea of what my plans are I probably wont be turbocharging my vehicles, but the difference in the NA Daytona and the Turbo Daytona as far as EF goes isnt very significant according to fueleconomy.gov
I do not know a lot about suspension does suspension play a large role in mileage?
