First off the car is a 94 cx stock. Recently i picked up a d16z6 with a y8 mani for a good deal, but unfortunately it didnt come with a harness. Now i got the motor in my car and used my exsiting harenss. It plugged up ok with some missing i.e the v-tec wires, o2 senor, not a serious problem for now . then when it came to the fuel rail it wouldnt plug in correctly, so i swaped over my i belive 190cc injectors from the cx with the 240cc ones and it went fine. pluged up everytinh else went fine. started it, amazingly it fired up but the timing was off.


Now my questions are:

With the smaller injectors will any problems occur? if i were to use the 240cc ones will i have to change harneses?
Should i get a v-tec harness and get it over with or can i wire my cx one for v-tec?
I am pulling up codes 10, 21, 41 what can i do to fix them?

Thanks

 

you can run the 240cc injectors
10- iat make sure its connected correctly
21 wire up vtec
41 o2 sensor convert the 1 wire to 4 wire o2 sensor.
what ecu are you running??
you can buy a vtec harness if you have the budget
otherwise you can rewire your cx harness for vtec, etc

 

Oh sorry im running a p28 ecu. If i were to fail down the lil clips/flangee things on the sides of the 240cc injectors to make them plug up to my cx harness will it work correctly? what do i do to my o2 sensor? how much would a v-tec harness cost me roughly? and is it ok to run smaller injectors for now? or will it casue problems?

 

just use a knife

 

bump for more answers

 

 

what year is your car????.. if its a 92 everything is wired from the computer to the engine bay... meaning you dont have to run wires all the way 2 the ecu...

its easy to do the 4 wire conversion... my first swap in my 92 cx was a z6 and i used the cx harness for a bit and just did the wiring myself

 

a 94 cx has a 4 wire o2 so all you need to do is extend the wiring
