LS swap questions
Ok, well Im going to put a 92 ls motor in my ef (91 DX), I wanted to wait and put a fully built ls/vtec in, but that is getting costly and I need to drive now! I think I have everything ready to go, just have a few questions:
1. My car was originally DPFI, but I will be using a CRX Si engine harness to covert to MPFI. Is there any further wiring that I will have to do? I believe that since I am using the Si harness, it should be plug and play. (I will be using a obd0 pr4 ecu)
2. Axles, Im guessing that 90-93 integra axles are correct??
3. Rear mount - Im using the old style Hasport b series mounts, do I use the 90-93 integra rear mount (from engine to hasport mount)?
4. Shift linkage - Can I use the shift linkage made for ef/b16 swaps, it should be the same, shouldn't it?
Thanks for the help!! I am hoping to do the swap this coming weekend

Ok since when is a 92 integra obd1 with a hydro tranny? i have a LS swap and i swapped a 93 ls motor which was obd0 that i had to convert to obd1 to work with my eg6. As far as i thought 90-93 integras are obd0 94-95 are obd1 and 96-00 are obd2...

It doesn't? I thought that the CRX Si Harness plugged into the civics (plug it in on the engine side of the firewall) I thought that wiring a b18a would be the same as wiring a ZC motor. I know the motor is obd1, but I plan on wiring it as a obd0, just to get up and running. I will be using a obd0 ecu.
If Im wrong, please let me know...and anyone have some answers to the axle and shift linkage questions?

Re: LS swap questions (awdriscol4)
You cant use the Si harness without a lot of re-pinning and modification.
The easiest way to do it is to modify the DX harness. Its really not hard at all. You just swap a few wires around and run a couple more for the extra injectors.

You have it backwards. He has a cable chassis (91 DX). If he had a hydro tranny, he would need the Hasport conversion kit. A cable tranny is the easiest way to go.
all 90-93 integras had a cable tranny
90-91 were obd0 and 92-93 were obd1.
obd1 continued until 95 and obd2 took over in 96.
For the axles, use 90-93 integra intermediate shaft and axles. For the shift linkage, you can buy a pre-made one from Hasport or another company that specializes in swaps ($$$ and is just a cut/welded integra one anyways.) or if you have access to a welder or a friend that can weld, take a 90-93 integra linkage and have it shortened approximately 2 1/4" (Double check the length if you go this route, but thats what I did on mine and it works perfectly).

Re: LS swap questions (Mr_CRX)
Bummer, sounds like its not going to be as easy as I thought then. Since I do want to wire it up as obd0, can I follow the guides for the zc swap or the mpfi swap? Im assuming its the same, just a bigger engine?
Thanks again

this guy seems to know what he's talking about more than anyone else so far but there is one thing that might be different. you use the 90-93 integra intermediate shaft and a set of 89 integra axles not 90-93. we have heard that the 90-93 axles might work but you have to remove the dust shield from the hubs. now we're not 100% sure on this but the last b series swap we did we used the 89 integra axles and they worked perfectly. also you need an obd0 distributor. you also have to use obd0 injectors preferably from an integra.

Re: LS swap questions (EFHondaRue)
You're right. I forgot to mention that you will probably need to remove the dust shield on the hub-end of the axle. It might bind if you dont.
I probably have the most mix-matched set of axles on my CRX. Thats why I know what works
I have a 94+ intermediate shaft with a 98 type-R driver's side axle. On the passenger side I'm running a 90-93 integra ABS axle.
People have said the ABS ones cause binding but I havent had any problems.
Ghetto? maybe. But it works for me with no problems
If you're going obd0, you'll need an obd0 distributor as was mentioned. However, I believe you can use the obd1 injectors if you eliminate the injector resistor box. I was running obd0 injectors on my obd1 setup for a while with no problems because I had that resistor box still in place. I dont see why it wouldnt work the other way around. Someone correct me if I'm wrong, but I think I remember seeing some people running obd1 injectors in their obd0 cars to clean up the engine bay/wiring a bit since it gets rid of that bulky resistor box.

for a guy who know's his ****. yea i was gonna mention that but i figured it's easiest just to use the obd0 injectors

Re: LS swap questions (EFHondaRue)
Ok, this might be a stupid question, but I heard that you can use prelude (92-96) injectors for the obd0 setup, is that true? (I believe they are also peak and hold injectors like the obd0 civic)
Thanks

Re: LS swap questions (awdriscol4)
And......let me ask this too...
They have a 91 ls motor at this place too, which is already obd0 and comes with the correct injectors and distributor. I was only going after the 92 motor for the SLIGHT performace increase and the fact that it was a much cleaner engine (cleaner looking that is). Would it be better to just go for the obd0 engine?? I mean getting injectors and a distributor isn't too bad for the obd1...but...just a thought

id go with whichever is in better shape mechanically. you should take apart and clean whichever one anyway. im doin the same swap: ls into a dx. i had a guy to my dpfi to mpfi wiring... he did a great job, reasonable price too. his email is: riceburner90crx@yahoo.com. tell him i sent you if you use him. you can do it yourself, it just saved me alot of time and effort. take notes and even pics of your swap, so maybe you can help me out in the spring when mine is ready to drop in. lots of work to do and parts to buy in the mean time. later on and good luck.

1. Using an SI harness is going to be hard work. It is MUCH easier to modify your DX harness to do the job. Also, coberting to use the 1992 ECU will result in the best performance and fuel economy.
2. You can use 1990-1993 axles. But they require removal of the steering knuckle sealing rings. Better would be to use SIR axles or their home-made equivalent. You can make these using the outer joints and shafts from a 1986-1989 Integra and the inner joints from a 1990-1993 Integra.
3. Regardless of the kit, you use the 1990-1993 Integra rear transmission mount.
4. A B16A shift linkage for a CRX is the exact same thing. And by the way, the 1992-1993 transmission is NOT hydraulic. It is a cable transmission. But it uses the larger hydraulic-style input spline.
