How tough would it be to do? I found a complete swap with engine, tranny, OBD2 to OBD1 harness and P72 ECU. I'm probably going to need a shift linkage and definitely motor mounts. I found a couple of threads that ended up dying with the question still unanswered. The asking price is basically what I'd pay for a low mileage LS and I don't want to pass this up. I just want to make sure I know what I'm getting myself into.

So if i get it, I want to work towards getting it CA BAR'd. My car is a '95 OBD1 Civic VX with a D15z1 and P07 ECU. The swap is a '99 GSR with about 110,000 miles with tranny, engine harness, obd2 to obd1 harness, and p72 ECU. Any help is much appreciated, thanks!

 

a obd2 gsr motor will drop right in a eg plug and play, just dropped one in like 2 days ago works perfect, plug and play

cliff note, the obd2 engine harness will plug and play to your obd1 car harness,

 

What else would I need exactly to make it it ref-able and smog? I want to make sure I know the job i'm getting myself into before i pick it up. Thanks, RHDCOUPE

 

to do a complete gsr swap, your going to need this stuff

gsr head
gsr block
gsr transmission
stock integra mounts or hasport b-series mounts
stock gsr axles
gsr halfshaft
p28 ecu
stock integra headers
what ever engine harness the engine comes with obd1 or obd2 will work plug n play
gsr torque mount on front of transmission
a/c mount to frame thats a ++ its nice to have

 

i just reffed a 97 gsr in my 95 coupe converted it to OBD1 and im running a 95 ecu

 

hes right about everthing except you can use your EG mounts and the ecu just depends on the year of the swap the main thing is to make sure everything is connect to something and cant be throwing any codes i think that was the hardest part was getting the codes off the visual is a peice of cake to pass

 

the drive side mount on single cam the out put bolts on the mount bolted to the motor are angled a lil the b-series mount the out put bolts are str8... and the ecu you want to run a vtec ecu chipped p28 is good

 

I didn't quite understand what you were saying about the mounts. So I will or won't be able to use some of my own mounts?

p72 not a good option for ECU? Figured i'd use it since its coming with the swap, but didn't know p28 is a better option.

Thanks for the input so far.

 

You have to use the p72 to ref but ppl say p28 is a better ecu and I thought you could use your same mounts but that other dude is saying no. Just google it

 

The tranny mount will fit but the driver side mount u need to change it to any b series motor mount and the back one u need a t bracket for it to fit right I'n.. Also people forgot the Axels need to be b series and ecu if ur motor was not vtec u need to run a wire from ur ecu or harnest to the vtec selinoid if ur car is obd1 and ur gonna get obd2 the destrubuter and alternator are different u eather wire them up or just use the obd 1 alternator and obd1 injectors I'm not sure about this one but the obd1 don't have the crank sensor and obd2 does and that's a problem..

 

if your car is obd1 and you are running an obd1 ecu you will be fine for reffing it. it would just have to not be throwing a code and be running properly with a cat to pass smog

 

But his car is obd1 and motor obd2 destrubuter is not the same the change unless u wire it up

 

NO you can't use that motor for REF. Been there, done that. First hand experience. Law states that the motor going into your car has to be of the year or newer than the chassis it's going into. It also states that if it's from a newer OBD, you have to make your car that OBD.

I REF'd a 96 Hatch with a B16A2 complete swap. I had to swap EVERYTHING over from the donor car, when I say everything, I mean EVERYTHING: engine harness, dash harness, chassis harness, AND gas tank.

To answer your question, YES the motor will work in your car with the OBD2 harness no problem, you can run it on either a P28 or an OBD-1 P72, your choice. And, NO you won't be able to REF that motor in your car, not without major work at least. If you have any more questions regarding REF you can PM me or post on this thread, I currently own 2 REF'd cars, and have REF'd over 7 cars in the past.

Good luck.

EDIT: I barely noticed the date on this thread. Waste of time lol

 

^^^ damn I didnt notice that either
but either way I thought the op said the motor was going into an eg so the motor would be newer than the chassis

 

Yes the motor is newer than the chassis, he's ok that part, or was ok, who knows lol ... But the motor is also from a different OBD1 than that of the 92-95 Civics... As stated in my previous post, he would have to convert the car to OBD2

 

No, negative. You don't have to swap "everything": dash harness, chassis harness, etc. If what you're saying is true then my friends couldn't pass on theirs. One of them passed his '97 hatch with a 99 B16a2 using a civic ex harness and obd2a P30 ecu. Another example, my other friend's '96 hatch passed with an obd2 B18B LS engine/tranny,ecu, no problems. They didn't have to do anything.

Pass visual/emissions = BAR'D. Simple.

Now, I've also heard the same thing from these white dudes from a local muffler shop. They said exactly what you're saying. I don't know if it's a "white" thing, but I call it BS.

 

Lol ^

But... I still have the GSR longblock in my garage and haven't gotten to work on the swap yet because it's my daily and I need to make sure I can get it BAR'D. Thanks for all of the feedback; I'm taking all of your opinions in consideration :]

 

You shouldn't call it BS, call around different REF stations and you'll see... I've also heard of what you are saying, people REF'ing their cars without much hassle, idk if it's up to the ref, lazy/strict, idk but the REF I go to is pretty strict, but he will tell you EVERYTHING you need to do in order pass it the RIGHT way. I've called the main REF number and various REF stations, and ALL of them have told me the same thing, which is what I base my information off of, and that's how I have REF'd my cars successfully.

And for the record, I'm not white lol

 

Yes. You can get it bar'd. I'm in the process of reffing mines. I just need to fix some minor issues. Run obd1 gsr ecu and cat. w/o cel's and you should be good. Sorry for bumping old thread. To "slowhatchcali", you can only believe of what people say or hear 50% of the time and the other half you just have to experience it.
