hey peeps i know there is a lot of info of these but i cant seem to find the right answer or am still confused.,. anyways

i got a b16 but its a jdm one to my info its from 96-00
am not sure wat kind of harneess do i need..
i dont really understand by the OBDI and OBDII..

am purchasing a P28chipped ECU dont know if it makes a difference!?

please help.. been in a single series for way too long..

your gonna want a 99-00 si ecu to run it and a obd2b y8 harness from a 99-00. granded u will probably loose one o2 sensor wiring because in ex's they were ran through the cab harness. u can take and repin one from ur old harness. or just wire vtec to ur current dx harness which i would find easier.

Your car is OBD2B. OBD2A is from 96-98 for Civics (except for HX which is wired OBD2A for 96-00). OBD2B is from 99-00 for Civics. To run the P28 you'll need an OBD2B-OBD1 ECU adapter harness. You can use your DX engine harness but you'll need to do a few modifications (3 wire IACV to 2 wire, wire in VTEC solenoid, VTEC pressure switch and the knock sensor).

being hes from cali hes gonna have problems tagging it using a obd1 ecu. even though this is probably the best way to swap but not if ur going to have emission issues.

Oh man, another thread of "how to swap". First things first, do it legit or don't do it at all. If you're not going to BAR it, I suggest you just turbo your D.

Judging by your post, you need to do a lot of searching and reading. There are info here that you can check out and read up on under FAQ. Being that your in CA as well, swapping can be tricky and if this is your first time. Hence like BAR referee. I just recently BAR'D my EH with a B18C1. So I'll help you what I can on that part.

Here's a list of what you need:

1) 99-00(EM1) Civic Si B16A2/S4C
2) 99-00 Civic Si axles/Rear T-mount
3) 96-00 Civic Ex/Si catalytic converter (if you can find it with the swap, great)
4) 99-00 Civic Si engine harness (should come with the longblock)
5) 99-00 Civic Si DOHC VTEC P2T ECU
6) Del Sol AC bracket

To make things easier, I would find a donor car that is wreck or just want to part out the whole engine swap. This way you won't be missing any knick knack parts and everything is original down to it's distributor and nuts and bolts. Also, try to find one that is low mileage. Take your time, get the right parts and do it right the first time.

These are the basics you need.

Here's the number to the ref station. 1-800-622-7733

ok well the car comes with the harness and being that its coming out of a 91 civic am guessing its a different harness..

the motor well thats the one i got am not looking for it I GOT IT!!
am not askin a "how to" but help cus like i said i dont understand the terms of OBDI and OBDII.. and since you guys are sayiing there cud be problems with the smog of the car so wuts the best option!?

Red_Army

bring it to a shop. tell them what you want. and pay them so you don't have to touch it.

crazyowes2000

You live in California, own a Civic, about to do a JDM swap and don't know what BAR is? You're in trouble.

crazyowes2000

LOL.. well honestly i have no idea of it and well like i said i been dealin with the stock d16.. this swapp came as a gift so might as well..

and thats the reason am asking.. cus am lost in all these.. i just wanna do it right and well with a lil more things in order to make a bit more power than usual..

crazyowes2000

ok so i b een reading and in order to pass the BAR thing..
i just gotta have the right ecu!! o2 sensors and stock cat!!

anything else am missing i know i might have to check for lean or rich incase it doesnt pass.. and for the wioring do i still do the OBD0 to OBDI or how is that!?

rhymeshark916

This is really what you should consider.

If it's coming out of a 91 Civic, then most likely it's been raped and it's OBD0 and its JDM. A few things to look for before you jump the gun. Do a compression test to see if it's healthy. Second. Is the head at least a 00? Reason why I asked is because I think the Ref stations(smog and inspection stations) smogs JDM motors now. If so you can use any JDM block but the head has to be the same year or newer. Next is definitely you need a Si harness.

I don't think you can put a 91 into a 6th gen and get away with it in Cali.

crazyowes2000

WELL THE MOTOR ITS 96-00..
and well they swapped it into that car ..

rhymeshark916

Yes you can. As long as the head is the same year or newer and it meets that year's emissions. So if he has a complete 2000 PR3 head with a JDM bottom end with the CFK sensor with a P2T ECU, he should pass inspections. Now, we can't tell if he pass smog or not, that's up to the sniffer.

crazyowes2000

ok so according to my friend the motor came out of a del sol which he says its a JDM motor .. and if am not confused that motor came to be the em1s..

am not trying to bar that thing..

so i would definetly need to use the si harness right?

efekek

I can't recall but it's from a crashed em1 im picking it up Sunday,and sorry for the confusing *** thread
