Ok i have a 2000 civic ex and im swaping in a B16a2 engine and trans in to my car but the mechanic said the car wont start because the ecu is not compatiable with my ex wireharness. he is useing the Si ecu and i have a ex wireharness. as i now all i wont have right now is the vtech connnected but will it start with the ex wireharness or no

 

if its a 2000 and you have the right computer(p2t) it will just plug in and every thing will work as long as it was a ex, including vtec(not vtech unless you woring about you cordless phone not working) a 2000ex to b16a2 is the simpleist swap to do every thing just plugs in all you need for the swap is the mounts(wich some you can use off your d series)

yeah what he siad ur harness is all prewired for vtec so idk what ur mechanic is talkin about.. time to get a new one. and i think the only mount u need is the rear T mount..

 

yeah i got all the mounts working right but can i use my old ecu from ex sohc or does my harness plug straight into the b16 ecu

 

ok but what ecu do i use the one from my ex sohc or the b16 ecu becuase my 2000 civic was non vtech so i dont have the plug for it to plug into the ecu

jesus man, DO YOU HAVE AN EX CIVIC WITH A D16Y8(VTEC) MOTOR OR NOT?!? if you do, then the EX wiring harness will plug right into the b16 ecu, which is what you need to be using for the b16. if you do NOT have an EX civic, then you will need to run the wires for vtec.

first you said you had a EX civic, and now you say your civic is non-vtec. do you just have an EX wiring harness laying around? if so, then use that for the swap.

 

i have a 2000 ex but i didnt know if it was a vtech or not IDK the mechanic is really messing around with me and i dont know what is going on the wireharness that im useing is from my ex but he said that the plug for the vtech does not fit also i need a new power steering line and ac lines because they dont fit please help with this thanks again for the posts

 

OK FOR THE SECOND FUKING TIME ITS VTEC NOT VTECH and if you dont even know if you car is VTEC than you need to go in to you garage and slit you wrist with a sorering iron, how much are you paying fot this swap $10,000 thats what id chare you since aperantly your a dumb *** and any info we give you will not help

 

Even if your car isnt VTEC The harness should still start the car. VTEC doesnt have to be wired in to drive the car, hence the fact of having solenoid issues where VTEC doesn't crack. Your mechanic is dicking you around and you obviously have no idea about what your getting into. You should have done a little research before buyin a Bseries swap to put into your car because if you did you would know that if your car was an EX it would be VTEC Already, no extra wires. If it is a DX then you have no VTEC Therefore u need an EX harness and you'll be all set unless you know which wires in the ECU harness to run from the solenoid to?. Which you dont. Take your car to someone who knows hondas not your local shitty hole in the wall where a bunch of grumpy old men work who all worship V8's and talk **** about hondas and 4 cylinders. Those are the ones who can build a carburator but dont know a god damn thing about an ECU or wiring harness. Your car is very un Prehistoric. Take it to an updated shop or do it yourself. Easiest swap to do. I was in ur place once when i did mine and the only way i got out of it was not by getting flamed on a forum but by asking the people i know with hondas and swaps. Im sure you know people around you with a swapped civic. Ask them to help you or read a book or something. Lose the mechanic.

 

And to add the AC and P.S comment.. DELETE AC AND PS .. you dont need it :-P although nice to have, id rather drive in an uncomfortable gokart with a DOHC vtec with no AC then drive in a honda with luxury. Hondas arent luxury cars unless u have an S2K but even then u have the race inspired setup lol! ... F00k AC. :-P

dude all that **** isnt needed.....nobody is forcing you to post so if you dont want to help him then dont. Somebody else will....and stop acting like you were born knowing all this......do you remember the time you didnt know jack ****??? Keep it moving man no need to be an ***.

 

Ok I'm the person you should be talking to. I have two Civic's, an Si and an Ex. What I did was rebuilt and swapped the B16A2 into the 2000 Civic EX which had the D16y8 motor in it. What I came across during the swap was that you do need the B16A2 Si harness because my group found that the <U>distributor plug</U> from the D16Y8 will NOT plug into the B16A2. Harnesses for the D16y8 and B16A2 are totally different.

The EX harness is the same as the Si harness. They both have functions for knock and VTEC. Who is your mechanic, and what is he smoking? It should be a 100% bolt on and plug in swap. You dont even need to make any pin or wire changes. BTW, I live in the chicago burbs. PM me if you need help or want me to take a look at it (on a slightly warmer day, lol). I've done a lot of these swaps.

Edit: Depending on your model year, and trim level, there are different distributor plugs. At the most, you'd have to maybe change those around a little bit. The 99-00 EX does have the smaller plug.


You wouldn't need new power steering lines. Just a different pump (SI). You can buy an AC adapter bracket so that your original EX AC compressor will bolt up to the engine. I think you can get one from a CRV or Hasport makes one. You only need a new line if you switch to the B series AC compressor.

I think your mechanic is a little inexperienced. You should take it to a speed shop or something. Mechanics dont know all the interchanges sometimes.

If you had an EX, you had VTEC. The EX ecu has provisions for VTEC and knock in the same pin locations as the Si harness. The EX harness plugs right into the Si's ecu. You need to use an Si or the JDM OBD2B B16A ECU.

here, I found you this:

Those two harnesses are not the same. Your fuel rail plugs will also be too short to plug into your B16A2 check out some of my pictures. myspace.com/r378504

Not on an EX. The fuel rail plugs are too short for the D16Y7 harnesses. The 96-98 EX and 99-00 Si have pretty much IDENTICAL wiring harnesses as far as the engine bay is concerned. The ECU connector is different.

The 99-00 EX and the 99-00 Si have the same harness except the distributor plug. You can solder on a distributor plug from a 96-98 EX or a 99-00 Si. You can even use an OBD1 plug with a couple mods or an Integra plug.

???????????!!!!!!!!!!!!!!!!!!! Where to start on this one?

S2000 a luxury car???? Since when? Much more importantly, the ONLY Honda luxury car? Are we talking about the HONDA S2000? Is there like a Mercedes S2000 out now or something? In all the time I've owned mine, I haven't really noticed luxury. You're aware that some models didn't come with a clock anywhere in the car, right? A 2 speaker stereo system...headunit out of a 85 Daewoo...the list goes on.

The AC pulley being run without the AC being on sucks up maybe like 0.5hp??? The PS pulley hogs up a LITTLE HP, but you can add like....an intake or something to curb that. Ever dated a female? They dont like to sweat when you take them out in your "dohc vtec go kart"? They like AC. Sitting in traffic also sucks without AC. So does driving in the 100 degree heat and humidity. Your sack may as well be an extension of your leg.

Also, Since when are there FWD go karts? Since when are cars like go karts? Especially since I'm almost positive the civic is an econo car.....

Sorry if I came off like a dick....it all just caught me off guard.
