Ok I installed a JDM CTR lsd into our Project Integra that uses a USDM GSR tranny.

I discovered that the Speedo and Odometer now do NOT function. After many tendious hours diagnosing the problem, I've discovered that the USDM LSD (and stock open diff) has this VSS gear on the differential housing:



I don't have a pic of the CTR LSD, however freom what I can remember, the CTR unit DID NOT have this VSS gear on the housing. Therefore the Integra VSS (Vehicle speed sensor) does not spin when the car is in motion.

Now the Speedo and Odo do no function at all unless we swap back the stock diff or aftermarket LSD to replace the CTR unit.

Does anyone know if there is way to use the CTR LSD on a USDM intregra transmission so that the speedo and odo will function??

Thanks.

 

ack! least you found the problem.

have fun.

here are some pics of the JDM CTRs LSD from what I read, the speed sensor is on th final drive or is separate from the LSD (see bottom of photo)

Thats not a picture of a CTR LSD. the CTR lsd and ITR is identical. all you gotta do is remove the speed gear from your stock diff to whatever you're working on. same thing with the quaiff

 

This might, or might not matter:
Check the 2000 USDM Integra Helms supplementm it contains documentation on changes to the LSD from 2000 on.

Food for thought,

Well..the site I got these photos from a CTR owners site...he even says that the speed sensor is built into the final drive gear.

 

in the second photo you can see the clutch plates in housed inside the diff. the type R units are Torsen worm gear differentials. That photo looks more like a KAAZ lsd.

 

the speed sensor gear is not on the final drive gear, only on the differential itself. SEF is right, the ctr lsd and the itr lsd are identical.
