VX swap questions
I have a 1974 Honda Civic which I made AWD by transplanting it onto a shortened 1989 Civic RT4WD floorpan/firewall (OBD-0 chassis). I've driven it over 100K miles since the transplant, with two different engines. Right now it is running a 1994 OBD-1 d15b from a JDM civic. I only get 30 mpg, which is a disappointment. I used to get 31-32 with the original non-vtec d16a6.
I picked up a cheap VX (d15z1?) motor from a guy who swapped it out for more power. What is needed to get the VX up and running in stock form? I've already got an OBD-1 jumper harness, I'm running an OBD-1 P28 ECU now. I've got the 4 wire O2 sensor. I've heard there is some component that needs to go on the firewall, or something, that is specific to the VX. I don't yet have an ECU. Brian http://i140.photobucket.com/albums/r...ivic4x4001.jpg |
A p28 and 4-wire isn't going to work for the car, unless you're planning to run california emissions, in which case you'll probably still need a cali vx ecu since I don't think anyone has dumped the rom for the cali vx yet. I would pick up a p07 and ntk/ngk 5wire or the swap really won't be worth it. You'll also need the additional wiring for the vx and the EGR controls.

Extra wiring would be vtec, egr, 5 wire o2, I'm not sure if there's any besides that if you are already running mpfi.
I'm sure it has egr, I can show you a picture of the egr valve on my engine if you want me to. P07 is the stock ECU The differences are just the o2 and computer. |
I'm already running OBD-1 vtec so I think it is just the 5 wire and the EGR, right?

that is a strange car
