H22A into a 89 civic si HB (wiring Question)
 

i have a Question about the H22a1 ecu. i have a 93 prelude and i want to swap the motor into my
89 civic si. i found motor mounts and axles but i dont know what to use for the ecu. my friend told me to
get the obd0 to obd1 conversion harnes and use a chiped p28 ecu, but i was wondering if i could use the
prelude ecu and wiring harmes, or ecu and ob0 to obd1 harnes, to make it cheaper.
any advice would help, i have looked and i dont see anything that aplies to me.Thanks!

run the 89 civic harness.

there is no real support for the p13 except a couple base map all motor proggies that are alright but if you want to really tune the motor go with the p28

does your h22 have an external coil? if so, get a jdm dizzy.

Re: H22A into a 89 civic si HB (wiring Question)
 

yeah it does have the ext coil, will it not work if i use this dist?

it's just easier to wire up your existing harness to the internal coil dizzy.
you can use the external coil, it's just a bit more wiring.
