Well I knew the gas mileage was going to go down, but this 3.0 has 194,000 miles and is just getting worn out.  I know I'm not going to get anywhere near a reasonable mpg with a lift and bigger tires, but I though anything would be better than getting like 9 mpg that I've been getting lately with my 3.0 and auto on 33's.  I'd rather stick with all Toyota stuff anyways and maybe add the supercharger later.  But it sounds like 3.4 with manual and 4.31 gear set and 4.88 R&P on 35's would be an alright setup.  But anything right now is better than getting the gas mileage i've been getting lately.  Thanks for the help
