So ive been doing some research for a little bit. Gathered mostly everything just need some confermation. Noob questions.

I have a 90 crx si that im planning to do an ls swap in. Heres the parts/to do list I have so far:

I plan on wiring obd1 and farther down the road going turbo.

ls shift linkage cut 2 3/8" or hasport
90-93 integra axles
hasport mount kit
convert motor to obd1 with jumper harnes
ls wire harness
my si wire harness
90-91 integra throtle cable
90-91 integra lower radiator hose trimmed
92 gsr upper radiator hose trimmed?
Stock clutch cable or ls clutch cable?
Make dent in frame rail for alterntor

I have a few questions..

1. Is everything here correct or anything need to be added? Please correct me as im sure I have made mistakes.
2. Would my crx clutch cable work or do I have to get one from an ls? I have heard good and bad things about both.
3. Axles.. I have read a lot of different stuff about the axles. Can someone who has done the swap let me know what you did?
4. Best ecu? And ecu for turbo in the future?
5. Is there a better way to go about any of these procedures?

Thanks a lot for reading and the help. I will really appriciate it.

 

1. looks like everything
2. your stock clutch cable will work with no problems
3. 90-93 axles and intermediate shaft
4. Best ecu would be stock ecu for motor
5. there is a good walkthrough somewhere in the FAQs

 

conert it to obd1 for best tuning options. need jumper , ecu i say p28 with base map or stock ls p75 i think , 4 wire o2 sensor it makes big dif did it on our da wth b16

 

X2. Don't forget the dust rings

I just did an LS (though obd0, so I can't say anything about the wiring) swap, into a hatch.. same as the rex I imagine.

I spent the extra $100 on linkage as well, got a deal as I bought it with the mounts, installed ES bushings while doing that too.. makes the shifter feel sharp.

The stock clutch cable works fine, I just had to work mine a bit to get it into the lever on the trans.. I actually trimmed some rubber off the end to give me a bit more room for adjustment.

I found this to be a pretty useful guide, though he did a B16:

And this one too(though its an a1):

I ended up piecing bits of several writeups together. I was noob too, it was my first swap, and my first serious work on a car (I'd only done suspension before).

Good luck and enjoy!

 

i like this one personally :p

lol, I just saw yours for the first time and was about to post it here. nice one! you included a lot of detail others seem to overlook, or decide not to.. i would have had this one out while i did my swap for sure.

 

^ stock clutch cable will NOT fit . you need one from a 90-93 integra. the crx one is too short. I know because i was running an LS tranny on my B16 and the cable didnt reach.

 

Thanks a lot for all the respnses and not bashing me for asking those questions. I did a lot of reading just read different things on those subjects so there was some confusion. Thanks again. I really apprciate it.

 

And those links are amazing. THANK YOU!

 

cool, i stand corrected. i didn't do the swap on a crx, so the clutch cable / reach must be different between the hatch and crx.

 

Are you going to use a hydro or cable tranny?

 

The stock clutch cable works, you just need to trim a small amount of rubber off the end of the cable where it goes into the clutch lever
