My daily driver is the Minion (96 Civic lx 4-door manual VX trans w/ LSD block & D15B dual vtec motor 37820-p2j-j62 (CVT)ecu)

I also have a D15Z1 motor ( I was intially thinking mini-me and turbo - forgive me! )

As I understand it, the D15Z1 motor has more torque, and less power in my normal highway rpm range ( 65-70 mph, 2500 max rpm ), and I should be able to do better for mileage with this motor versus the dual vtec D15B, correct?

Next question - hell, I already know, but I'll ask anyway.. I bought a second VX tranny from fellow ecomodder turbovr41991 (one left, I think info here: http://ecomodder.com/forum/showthrea...ale-28931.html), and I'm rebuilding it. Would I get better mileage with an open differential or a limited slip differential?

Thanks in advance,
Victor
