I'm looking into getting a samurai as its probably the most fuel efficient 4x4 out there. I'm just wondering with all the different engine swaps that are common with samurais, what kind of fuel economy are people getting with their different setups(engine, gearing, tires.) My friend has a 4runner with a modded 22r and once he put bigger tires on the thing started drinking gas like crazy because its still underpowered and he has to rev it fairly high. Is this a common problem for samurais as well?
