first off i have a 1996 civic dx hatch. wiht the stock y7.
the new egine i have is a d15b8 block with a z6 head y8 manifold and a y8 tranny. axles full obd1 harness and motor mounts
i have a obd2a to obd1 conversion harness and i plan on getting a p28 and z6 dizzy.
1. do i use the stock harness and wire up vtec or use the z6?
2. do i need to get a z6 dizzy or can i use the dizzy jumpers
3.i have integra injectors will they work?
4.what other problems will i run into?

i am confused by how much threads there are. just wanted to clear things up

 

1. Use the stock harness or get one from a 96-00 EX for plug and play. If you use the stock harness you'll need to wire up VTEC solenoid, VTEC pressure switch, knock sensor. Also you'll need to convert to a 2 wire IACV (http://www.ff-squad.com/tech/wiring/wiring.96-98.jpg, http://www.ff-squad.com/tech/wiring/...in_removal.jpg).

2. Use the Z6 dizzy with an adapter harness.

3. Are they OBD2? Then they'll work plug and play. If they are OBD1 you'll need to remove the blue tab in the injector connector plug itself and it'll plug in (http://ff-squad.com/tech/wiring/obd2-1injclip.jpg). If its OBD0 then forget about it.

4.Using the Y8 manifold you'll need to relocate the IAT into the intake arm, most aftermarket intake have the location for it in the arm itself. What exhaust manifold are you going to use? If you reuse the Y7 you won't have to do any modifications other wise if you are going to use the Y8 or Z6 you'll need to relocate your secondary O2 by using an extension harness and a Y8 catalytic converter. What ECU are you going to run? OBD1 might be the easiest as you won't have to worry about the CKF sensor by the crank pulley as the B8 block doesn't have it. Also it won't look for a secondary O2 so you can do what you want with the header and exhaust. Let me know if you have any more questions.

 

thanks for the info. i plan on running a p28 if i can find one close by me for a reasonable price. and im pretty sure the ls injectors are obd1 because the guy said he was running the motor. but you never know

do you think its easier/cheaper to wire up the vtec stuff myself. or just get a 96-98 harness

i am going to use these after market headers i have. they work on my y7 so i figure theyll work on the z6
