I have a 1999 civic si (canadian, so d16y8). I am planning on putting a 1996 b18b1 in it this winter. I am wondering where my car is OBD2b will it match up to the OBD2a in the b18, or do I need a conversion harness?
Also do I use the stock 99 si harness and ecu and just change the distributer plug? And is there any other wiring that will need to be changed?

I know this has probally been asked a million times, but i have had a hard time finding a direct answer. I have never done a swap before. Sorry about the repost everyone!

Thanks for your time,
Jacob

ive gotta ask: why a ls swap? power gain is minimal, tq is not very significant. if youre going to put yourself thru it, AT LEAST go b16.

-__-

he has his reasons...maybe it was cheap? maybe he wants to turbo? maybe he wants to do an LS/VTEC? maybe thats all he could find? maybe cuz b16 have no torque and he wanted torque?

i assume your car has a manual transmission? anyway, you can use your stock obd2b harness and use an obd2b LS computer. u may have to splice on a new clip for a couple things but its not hard. dont forget axles, mounts, transmission and shift linkage. good luck

Dammit. Someone give ME a swap for free. I live in Oak Ridge TN. I'd swap that in and boost it.

Use a conversion harness, all the OBD2B Integra ECUs have an immobilizer and can't be used unless you have it removed.
