Wow you guys LMAO. My civic has a D15 with SL3 transmission. I get 70 mpgs out of my car on the hwy and 40 around the city. Extreme stop and go I get 32 mpg on a hot day. The SL3 transmission is a SI transmission but I rebuilt it. with different gear ratios per gear. My 5th gear runs a low rpm cruising. I have a 70/30 lsd locker as well. I thought it was funny bout the mpfi swap. More air/More fuel. More Fuel/More money
Linear Mode
