Im returning over 50 mpg in my saturn with a belly pan, its at 2000rpm at 65 mph and runs over 8psi vacuum on flat ground. 1.9L/3.1L*2000 = 1225 rpm equivelent displacement so it will have 10% more umf and 40% more weight than the saturn. Might be as slow accelerating as an unassisted Insight in lean burn. Id like to gear the saturn up more. Weight is 3600lb vs 2500lb. 120 hp is at only 4200 rpm, I doubt if my engine will make 120 hp, with hot air intake and all. What do CRX HFs run, 1.5L@1900 rpm at 65 mph, 2300 lbs. 3.1*1350/3600 = 1.16 1.5*1900/2300 = 1.2. So it will be struggling 4 % more than a CRX at highway speed. Definately willl need a belly pan and and full front and rear skirts, starting a CD = .30 is not too bad.. OK so 1350 may be a bit slow but not out of the relm. I could use a 3.06 final drive for 1440 RPM, but my wife likes to drive at 80 mph. 1350 would be fine for the 3.4 or 3.8 engines.
