Hey guys. Here's my first "from the ground up" project.

It's a 1990 civic hatch Si. If I'm not wrong these were mpfi??

My buddy picked it up in chicago and decided he didn't have time to work on it so he brought it down to me. I bought it for $160. It came with some one-off steering wheel, Walbro 255 fuel pump, and brand new quarter panel pieces. They had rear discs on it but gave me drums.... :greddy:

Picture time:


















sunroof ^_^










Those are all the pics my buddy sent me before he picked it up. I haven't taken any new ones since I got it.

The only thing I've done is new rear brake hoses. Bout to start putting more in it.


Plans:
-JDM B16b.. I know.... NOT a D series but my fiance is helping me with the build and that's what we decided to put in it. That swap will come the an LSD transmission
-OBD1 conversion. I'd like to be able to tune this sucker and I really don't like OBD2 but I wouldn't know how to go about using an OBD0 car with an OBD2 engine and converting it to OBD1... Some research I'll have to do.
-POSSIBLE JDM front end. I really don't like the USDM hood so it's at the least getting a carbon fiber JDM style hood if I can't find a solid front end conversion.
-Almost picked up a RHD conversion but it didn't come with a steering rack and he wanted too much. but this would be nice if I can find it.
-Full wire tuck of course.. take ANYTHING unecessary out. this will just be a summer play car. it already has a stripped interior and no heat or A/C. we'll see about a radio
-Full rust restoration including quarter panels and chassis. Just clean everything up to make it last another 20 years.
-New paint of course. either blue or black.

That's all we have planned so far. I wanted a project I could officially say I BUILT. This will be a slow build so updates will be few and far between. Keep an eye out!

 

Yes the si came mpfi already!!! So that will make it all the easyer to swap the b16 into it. Good luck with the build and deff go obd1!!

 

who doesnt know the si was mpfi and the dx was dpfi? lol j/k..looks like you got alot of work ahead of you. i sold my last 90 si hatch shell for 300. had everything but the motor and axles, like carpet, si seats, a dash...

 

haha ya I was kind of excited when I read that it came with mpfi.

at the moment I'm on the search for a gauge cluster, hood, fenders, both bumper supports, headlights/taillights, B series shift linkage, and a passenger seat. I found a 4dr around here but it's automatic... so I really can't steal anything off of it... >_<

I need to re do the rear brake lines between the long line and the hose. They broke when I was changing the hoses. no big. then it gets new rotors and pads in the front. I'll probably just stick some wearever Silvers with wearever rotors on it at the moment so I can at least get it to brake while I'm moving it around. Eventually it's getting HAWK pads with Brembo Blanks.

If anyone has any of those parts laying around hit me up.

 

well... finally got around to getting back to this project. picked up a 91 DA as a donor. b18a1 and full disc brakes. Also have Innovative b series mounts for the swap and a brand new b16 shift cable. I will be shortening my shift linkages.

 

Ok I came to a brick in the road. I got to looling at each car and and I realized the wire harnesses are COMPLETELY different. THe teg has the resistor box and the map sensor stuff bolted on the firewall. THe hatch doesn't have anything. and the plugs to the body harness are different. I didn't get an engine harness with the hatch... should I just convert the whole body harness over??

 

buy a si engine wire harness not worth swapping the complete harness over.
i have a spare si wire harness if you want it just pm me a offer

 

The harnesses are exactly the same other then like two wires. I just did a b18a1 in my si. you can us the teg harness

 

^ah i wasnt sure if they were the same or not

 

Oh really? if this is so, then why do so many people NOT use them and why doesn't the harness plug into the firewall plugs on this car?




Your civic is missing the map and resistor box which are supposed to be mounted on the firewall above your fuel filter. Look up some engine bay pics and you'll see how it's supposed to be.
You can use the teg parts so you don't need to bother getting the Civic ones.

As suggested already, you should get an Si engine harness. Way easier than swapping out to the teg harness.

 

Ya i looked at the map sensor/resistor box thing and I feel like a dumbass now...

And yes, the plugs to the body harnesses are WAY different. the driver's side on the teg has a 14 wire connector and a six prong connector. the hatch only has like an 8 something wire connector on the drivers side for instance...

 

Plugs don't mean anything. Its the point that its obd0 it'll plug into your main harness plugs on your back corners of your bay. There is more plugs probably because its a different engine and different sensors. Like cruise control and ****..actually using that engine harness would probably be simpler then finding a si harness or dx converted

 

Your post is so full of fail it's amazing.
Not only are you wrong, but you are wrong.
Oh, and you are wrong.
And you are also wrong.


The plugs that don't fit are the ones in the corners.
The OBD version has nothing to do with it. If OBD did have something to do with it, then you could plug a Nissan harness into a Chevy and it would fire right up.... but it doesn't.
It would be easier to find an Si harness.

 

This is almost "signature" worthy...

Oh and by the way, the resistor box is on the driver's side shock tower and not obove the fuel filter on the MPFI Honda...

 

What i am saying is because he has the whole integra..he can just swap the damn thing over and save money..

 

No, what you are saying is that the engine harness plugs right into the Si chassis harness.

 

LOL

bro, just find an SI harness it will be so much easier, all plug and play. the map sensor goes right above the intake manifold near the throttle body and the resistor box goes on the drivers side shock tower. i just did a b18 swap in an obd0 crx using an si harness, i'll post some pics for you when i can to see where things go.

 

nice.

 

I know where the resistor box and map sensors go. I just had a brain fart.

I found a couple si harnesses so it'll just be all plug and play. thanks for the clarifications

 

have you ever swapped an entire car harness over??? didn't think so Not worth the time/effort. If I wanted to do that I'd swap over a DC integra harness and run OBD1

 

Well I've got the motor pretty much in. progress has been slow due to more hours at work... I've never had such a hard time lining up mount bolts as I had with this one... stupid poly mounts... >_<

Just waitin on a wire harness before I go bolting everything back on it! should be shortenin the linkage soon too.

 

I just finished swapping to obd1 in my 88 just because my cars wiring is trash and I got the car for free with the multipoint swap but it doesn't run because of the harness issues so I had a diner car already 94 hatch easy as pie if you know what you're doing takes a few hours. But now its obd1 all the way from the fuel pump to the headlights.

 

Im actually going to post a thereafter on how to do it when I have time. If I were you I would. Start. With the body and strip it down a get it painted then do suspension and brakes then sorry about the motor and wiring

 

:thumb down:: thumbdown::thumbd own::t humbdown:


you sir are the epitome of stupid.. both cars being obd0 has nothing to do with it. you have to use either your original harness and add the plugs/wires or use the SI harness.

 

yea our map sensors bolted onto the firewall.
BUT! you do not need the resistor box if you are using OBD1 injectors.

resistor box is only for low impedance injectors..
that little distributor plug (blocked off plug) on the driver side of the integra, you can use that if the SI harness doesnt already have it.

i used an entire DA integra harness, and utilized almost all of the wires, and some of the plugs, to convert my obd0 std 91 hatch to a fulll obd1 harness. and i didnt use the resistor box.

good luck with the build
