Hi all im about to convert my 88 crx dual port to multi port but have ran into a problem.


I have

multiport Dizzy
OBDO injectors
Wire harness with resistor box
PM6 crx si ECU

ok on to the bad.

The intake mani i got with the swap is a HF. i dont want the little manifold.

So on to my questions. I have a complete D16z6 manifold. i removed the injectors and put the OBDO injectors on it. but the hf fuel rail wont fit. so i put the Z6 fuel rail on them it seems a snug fit.

So will this intake work????? on my 88 rex? with the multi port swap???? has the Z6 throttle body still on it.

Now another question how and do i have to hook up all the stuff like the IACV??? the cold start valve???

What can i remove and still have the car running without any check engine lights????



Thanks all Rep will be given!!!

 

yes it will work you could have eve used the injectors preObd and obd1 are near the same.res box or not..YES I WOULD USE the z6 Tb cause of the mapsensor then you can get rid of all the vac hoses on the firewall makes it alot cleaner

 

thanks man....

I thought the OBD1 injectors were different???

i have a set of the OBD1 injectors. Could i use those??

just trying to get my facts right before i even start on converting it.

 

well i dont want to say yes yet,i never had a problem useing them high or low res. even with a resistorbox,maybe someone else can answer cause i dont answer something unless i know for sure,but i have done it.i only say it cause my motor was a 00si b16a2 i have in my 89 civic hatch and i used those obd2 injectors with no problem cause i had the harness.and it looks alot nicer with no firewall crap

 

If you want to run the OBD1 or OBD2 injectors, you will need to remove the resistor box and solder the five wires together.

 

obdo injectors are peak and hold, thats why you need the resistor box.

obd1 injectors are saturated, I wouldn't use them at all, but you can use the z6 im and tb, all the plugs are the same. You can also use this site for reference in doing your MPFI swap. This site also has the ecu codes and meanings. I told you I would help you man.

Hmm....

thanks guys.

Well on to one more question.

Witch injectors to use??? OBDO or OBD1 Z6 injectors???

 

obdo injectors in the Z6 im. And take that Si sticker off your car.

 

the odb1 injectors could be used if wired properly and would help clean up your engine bay
