My old one which was same gears and same tire size I'm going to be on, I used to get about 18 around town in San Diego with it. Only difference is that one was 4 speed auto, where this one is 5 speed manual. I'm hoping to be about the same. Honestly, the 31's with 3.73's in it... It's kind of a dog and underpowered. I'm thinking when I bump to 4.56 and 33's the engine RPM's are going to come up a bit better and I might actually see a little increase in mileage. If it was a highway cruiser this would be a great setup but around town light to light it's a bit under geared. I did get smoked off yesterday by a flat bed semi truck! Shows how slow I drive.
Best part is everything looks on schedule for me to have this expo 100% finished short of a winch by May! I'm talking painted, tinted windows, stereo system, all the suspension stuff, bumpers, etc...
