Hey i have a 91 CRX DX with a d15b2 with DPFI and im swapping in a B18b i heard a ZC Wiring harness would work is that true?

 

Just use your existing wiring harness and add the necessary injector and distributor wires. What ecu will you be using for your swap?

 

you heard wrong.

 

well if your going from obd0 to obd1, which you should be, then you'll need an adapter to make life easy. Rywire sells them, so far so good for mine(3yrs) and made everyting really simple.

Of course you can stay obd0 in which case the above is right on the money.

 

you can convert to obd1 and run it with a p75, or just stay obd0 and run it with a pr4. like was said above keep your stock harness and convert it from dpfi to mpfi.

 

so all i would need to do is change my wiring from dpfi to mpfi and im good?

 

i was planning on sending it to rywire already i just dont have a b18 wiring harness so could i send my stock d15 DPFI wiring harness and the Zc wiring harness to rywire?

is this the right one i would need?

yep that will work. it says "or an equivalent mpfi harness" so the zc one should work fine.

 

ok thanks alot everyone!

 

I have 91 si 1.6L. SPoke to a guy about swapping b18b. buy says I need to extend a wire, but he didn't say so which wire? and how long is that clutch or how short should the integra be? overal which wire should be longer and length of stick shifter?

 

Sory I have a quick question, I have a 91 si hatch, already fuel injected. Want a b18b swap, which wire needs extension, and what type of wire do i use, and how short should i cut that integrea shifter?

 

For one you'll need to swap the fan switch from the back of the block (first pic yellow arrow) to the thermostat housing (second pic red box). Possibly some more if you decide to use the throttle body MAP sensor (third pic) as opposed to the firewall mounted one (fourth pic).

 

Im dropping in a B18b or just found out today possibly a B18c. If I go with the b can i use a pr4? It looks like OBD1 because it has three separate ecu plugs. Is this right?

 

so how short is that shifter from the integ into my 91 si
and so swictch the fan swithc wire just a litle confuse the pick are great

 

and do i need to make that wire longer?

 

what do you mean swap the fan switch from that back of the block to the thermostat housing? I am sorry really new to this swapping?

 

just extend the wires from the fan switch in the back the two little nipples things cut them get a two wire plug from anywhere solder them so it plugs to the fan switch on the thermostat housing make sure u dont put them in wrong order or the fan will blow it the oppisite way because b18b dont have the fan switch in the back they have it on the housing...
