i have a 1990 civic si with a OBD0 b16a and i wanted to put a OBD1 b16a into it since my old b16a blew up. what all do i need to get for the car so far i know i need the jumper harness for the ecu and dizzy and i plan on using my old tranny. do i need anything else?? thanks for your help

I suggest contacting rywire, boomslang or another harness maker. You will prolly need something like this. http://rywire.com/store/8891-crxcivic-si...-p-71.html

If your car is US spec it should be housing a D16A6, if it has a B16a in it then it's already been swapped. If it's already been swapped to an OBD0 B16a then I really have no idea where to start as I don't know what's been done yet.


Just remember, if you want to use an OBD1 distributor then you need an OBD1 ECU. The OBD0 ECU won't work with the OBD1 distributor.

i swapped in the OBD0 b16a a while back it did have a D16A6. i was going to buy a OBD1 engine from hmotorsports so it would come with the dizzy

Ok, this helps a lot. If you used simple adapters to do the old swap then it shouldn't be an issue, just use adapters again. You can also have a whole new harness wired from the ground up. Try and get a motor that has the ECU with it. It's not really an issue finding an OBD1 ECU as lots of the OBD2 guys use them so they can run Hondata.

From everything I know, this should be a pretty easy swap. Considering you already had a B series in there the new one should bolt right in. Connect the proper ECU with the wire adapters and you are good to go.

alright thanks alot for the help. time to order the engine and ecu
