I have recently killed my OEM block (D15B1, DPFI), and a VX motor fell into my lap at no cost. I know I need to do some work to my wire harness and get a different ECU, but that would be the extent of my knowlege of the D15Z1 Vtec-e motor. I am also more concerned with fuel economy rather than top end power, so please do not try and talk me into another swap that would produde more power in your opinion. I am seeking information on what ECU I need to pursue using/acquiring in addition to what route I need to go with my wire harness. FYI, the transmission that came with the VX will also be discarded as I will simply use an 89 CRX Si transmission to keep the clutch cable operated. If any of you know what ECU to use, what additional items I might need to make it work correctly that would be greatly appreciated. (axles, throttle cable and intake/filter have already been thought of and accounted for) Thanks guys!
