B18A1... what's the difference (NEW QUESTION 12/27)

In researching about a potential swap, I see that the '90-'91 integra B18A has 130hp, while the '92-93 has 140. Same boreXstroke, same CR, blah blah...
What changed? Cams? Fueling? ECU?

TIA.

Comments

  • Definitely the ECU. All cars went to OBD1 in 1992. What else I can't say.

    Cams were slightly different too. If you're going that route I'd recommend a B20 over either of them, the torque difference is substantial.

    Thanks. I found on ef-honda that the cams and possibly intake were different.

    IF I do this, it'll be a complete parts car, preferably OBD0, cable clutch. I was just wondering where that extra 10 was :lol: May pick up the teg tomorrow, if time permits.


    anybody have some used mounts?

    Why would you get a complete parts car?

    Still easier to just buy the parts separately, and you won't have a junk shell to deal with either.
  • This is what a friend of mine and I are going to be doing. I would like to buy a whole car as well. I have figured it would cost about 1200 - 1500 including motor mounts, depending on what you want to buy.
  • bam-bambam-bam Council Member
    $500. whole car. runs. can sell off what's left or crush it.

    I don't see where it's easier to try to find/buy everything separately...my time is worth more than that. I've been scouting for awhile for a donor car.

    Damn Bam! I saw you called me the other day but I didn't hear it ringing. That's awesome you want to swap! Scots wagon bit the dust, threw a rod. You called it. I guess I need to do a swap sooner than later. I hit 188k today!

    I disagree, but to each his own I guess. Best of luck.
  • Recently there were two separate 90's intergras for sale on craigslist here. Both were wrecked, but running. They were each under $600. I think that is the best way to go for all of the parts. We have a just few salvage yards here that are ok, but they are usually picked pretty clean. :?
  • bam-bambam-bam Council Member
    Update! I bought the swap last night.

    '92 Integra RS coupe/hatchback, runs and drives well,front end damage. Paid $550 with a salvage title.

    Anybody need some Integra body parts? :lol:

    Don't forget to take the dust seals out from the backside of the spindle to make use of the 90-93 axles

    thanks! what about if I use the DA knuckles, brakes, etc.?

    ive never had to with da to da or da cv/axle to da hub.
  • bam-bam wrote:

    They bolt on, but they do change the camber quite a bit. With your car being stock ride height I think you'd have some pretty crazy positive camber. The only knuckles that bolt onto any EF/EE chassis with the big brakes that doesn't have an effect on camber are the 1991 Civic Ex 4 door knuckles.

    There was a topic here in this very forum a while back discussing DA knuckles and their affect on EF/EE camber, but I cannot recall 100% if it was positive or negative camber they add - I'm pretty sure it's positive.

    I personally have DA knuckles on my wagon, but my car sits pretty damn low and I also have upper control arm camber kits so I can't say from experience I've swapped DA knuckles onto a stock wagon to say how much it changed camber, and which way it went.

    BTW:

    Either way DO IT. The front brakes make a huge difference in stopping on these cars. You'll also want a 15/16ths brake master cylinder to replace the stock 13/16ths unit. I think you might be able to use the Integra RS one - you'll know once you look at how the mounting ears are clocked on it. If the mounting ears are the same then it'll work. If not then for sure a 1991 Civic EX one will bolt up like stock, but it has the bigger 15/16ths piston size in it.
  • BTW for clarification the DA knuckles will throw the camber to the positive side, and at stock ride height it will probably be way too much positive camber.

    It would probably level things out if you lowered the wagons some though....

    QUESTION: I need to send a dpfi harness and the integra one to have a obd0 dpfi to obd1 mpfi made.

    ...Will the harness from my automatic partswagon work as a "core", or is there some difference I'm not seeing?
  • If you are sending it to rywire it doesn't matter.. I sent my auto core to them and they sent a manual one back.. just make a note of it when you send it.
  • bam-bambam-bam Council Member
    Thanks. I ended up taking the auto harness and putting it on my car. Wiring appeared the same, except for rev.light...

    Cranked up fine, no CEL, but auto-belts don't work. wtf? The seatbelt light in the cluster came on, and both belts 'opened' when the doors were opened the first time, but after that, nothing. :?

    edit: The whole cluster isn't working. I don't think it's related to the engine harness, I probably blew a fuse or something. No worries, it won't leave the yard again with that engine 8)
  • bam-bambam-bam Council Member
    The B18A1 I pulled out has an EGR valve.
    The '92 Teg's harness has no provision for said Egr valve.
    I pulled another harness today from a '92 Teg....it has an EGR plug. WTF?

    How can you tell what head you're looking at? It appears that the head and the bottom end of this engine are of different vintages. OK with me, really, since the head and intake look fresh, I may not have to rework them.
  • Most of them will have a casting code on them somewhere.. Mine has a PR3 casting..

    The belts could be due to the fuses on the battery terminal.. Did you unhook those?
  • bam-bambam-bam Council Member
    The fuses at the battery are ok....that's about as far as I went. I decided not to waste time with it. It'll run long enough to get it in the shop to yank the motor. Gas prices are down, I'm just driving the Xterra to work.

    Header? Anybody have a recommendation? I've seen from $50 ebay up to $800. What's the compromise? I feel like a decent one should cost about $150 or so...or maybe that's just what I'm willing to spend.

    Question: The axles from the '92 integra will work in my wagon, right? I got them in tonight, but they feel too long. (very little end-play, even with front end suspended) I haven't put it on the ground yet, but it looks to me like they will bottom out.
    Is there a shorter axle for Bseries?

    :) they are the axles to use, they do seem tight but its not a problem at all. there are 86-89 teg axles they are shorter but bad things happen when you put them on 4th gen swaps! i used them in a pinch one time and they pulled apart one the first turn, ruined a new set of axles for my 85 crx. :x
  • bam-bambam-bam Council Member
    Thanks. They just felt weird to me. Feels like they'll bottom out.

    I spent most of yesterday trying to shoehorn the AC, condenser fan, lines etc in.
    Still have an O2 sensor code- I hope it's just the sensor (not the added obd1 4 wire mess)
