Check out the build thread. Basically it's a lx sedan with a d15z1 swap. The EPA rating I got for the factory lx was posted on fuel economy.gov and is the revised 2008 edition. First goal is 50 mpg tanks with no eoc,no aero, no p+g, only block heater usage. second goal is 55 mpg by adding afr gauge, grill block, underbody pans, and eoc if needed. last goal is 60 mpg using all the above and max hypermiling techniques.
