Motor Change guide for EG * B / D / H / K SERIES !!!!

[specialst]

i have a civic with a zc crx harness and want to know how i can make it possible to run the b16a in it and also is there any other dissy that can be used to replace the td22u obdo distriubtor or if any magnetic pick up off any other honda could replace the td 22u one

replace the harness with the B16A's respective OBD 1or2 harness and ecu. makes life easier to just rip the old one out and put the new one in. no messy wire chopping and joining. also, your crx has non-vtec ecu thus i dont think its possible to run a b16a (obviously a vtec engine) off it.

i have a civic eg5 with a d16 sohc vtec engine. if i put a b16a2 into a eg5 do i need to change harness? or i can keep the harness just change a ecu?

I've just done that exact thing

You can as I have but need to wire in the knock sensor and 4 wire 02 sensor to the ECU that cames with the motor

[Kevin99543]

so the harness should be fine for my new engine,right?

Yeah if your B16A2 has an odb1 ECU

I got my EG5 but I wish I had a good nick B16A one to make life eazier

[Kevin99543]

yeah. i havent got the ECU yet,so u suggest that i get a odb1 ecu?

You have to if you want to use your EG5 loom or spend $$$$$$$$$$ to conversion harness

if u have a Vti
the b16a will drop straight in as it already has wires for the VTEC solonoid and oil pressure etc
and ECU has to be a OBD1 B16a ecu

[Kevin99543]

currently,im trying to connect o2 sensor to the ecu...its a 4 wire o2 sensor...but my old harness only come with 1 wire....
so anyone has the diagram?

Yup

Just lookup 0db2 pin outs and connect accordingly

But why are you wiring up a odb2 sensor when your cars odb1?

jdm b16a's have 4 wire 02 sensor
doesnt matter if it's obd1 or obd2
