OBD2 Swap into a 90 CRX
Hi everybody ... my friend is doing a 96 GSR swap into his 90 crx, he doesn't have a computer so he asked me to ask you all you wonderfull guru's about it. 
He also wants to run OBD1 so he needs to know all the wiring changes, distributer changes, what axles to use, you name it.
So ANY help and/or parts your selling (OBD1 GSR ECU, OBD1 Dizzy, and axles that will work for the swap) will be GREATLY APPRECIATED. Also any sites with directions would be sweet too.
Thank you all very much

Go with a 1994-95 USDM P72 ECU or a chipped P28 or P30 if you are using a single stage manifold (like Skunk2).

You need an ODB0 to OBD1 ECU adapter harness. The wiring changes can all be found on here if you search.

It really depends on the tranny and intermediate shaft you are using. I would personally go with 90-93 Integra intermediate shaft and axles. If not that then go with the 94-01 Integra / 99-00 Civic Si intermediate shaft and axles.

My friend just bought a 99 Si hydro tranny, so what axles should he use? the Si ones or integra ones.
thanks

The 99 Si hydro tranny will only work if you get the HASport cable to hydro setup or do a custom hydro clutch. If you haven't bought the mount kit yet then you might consider the HASport kit then you could actually use the Si hydro tranny. If not, then you'll need to search for a B series cable tranny.

Re: OBD2 Swap into a 90 CRX (VTECVillain)
To clarify, I have a 96 gsr motor with a 99 si tranny. I already bought the hasport hydro conversion, motor mounts, and hasport shift linkage. I plan to run obd 1 since I heard it's the best so I boiught the obd0 to obd 1 conversion.
I'm well aware that to do this I need a better manifold, so I bought the skunk 2 intake manifold to get rid of this problem. I also have clutchmasters stage 3 clutch and lightened flywheel. But with this, I still need some help.
My motor didn't come with a distributor, and I could easily buy the 96 gsr one, but I've seen others used an obd1 distributor for some reason. Is there another distributor I should use instead?
Also, I have the 96 gsr midshaft, but I don't' know what axles I should use. What axles will work best for me?
And finally, I don't' have an ecu for the car. I know that several ecu's can run my motor, but I wan to know which one is best? I plan to chip it and wan to know what chip is good too. I know skunk 2 and jun have quality chips.
Also, if you know any information on adding the sensors I need to the harness let me know. I know I need to add a v tech and a knock sensor. Also a second o2 sensor needs to be added, but any ideas on how to add them? Any information on these sensors will help because one of my friends is good with wiring and diagnostics, but only knows domestic cars, so all he needs to know is the basic idea of what to do. Thanks.
