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

 

check out= http://www.rywire.com/catalog/ or call them (240-479-9473)

 

$500.00 for a wiring harness ...... are you crazy ?

 

Alright. So ill need to find a obd2b ecu for the ls. I cant use the obd2a ecu.
And yeh its 5 speed.

 

because i was given a complete swap for free. whats wrong with a ls swap, mroe power then a 1.6bsohc?

 

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.

 

alright thanks. what do i get for a conversion harness, 0bd2b to 2a or the other way around.

 

OBD2B to OBD2A

 

B to A

"OBD2B to OBD2A ECU jumper harness to install a 96-98 civic or 96-99 integra ECU into any 99-00 civic or 00-01 integra chassis"

 

i also need help on my first ls swap into my 99 civic d16y8,i got it for cheap thats why im swapping this,
what will i need to swap it,they told me i needed a obd1 ecu and ls harness
t bracket and si sidepost,b series mounts? is it true?

 

This must be a Canadian Si? Same as the US EX i am assuming if you have a sohc
