Is there an easy way to tell if my CRX has an LSD added? I know that the DX didnt come with one, but I dont know the history of the car. It was lowered with Konis all around and the previous owner did autocross it. Maybe an LSD was put in as well?
It seems to me it used to be if you turned one wheel in one direction and the other turned also the same direction? Or some such nonsense. Any suggestions?
Edit: I was wrong, my bad
oh also i guess i meant front, but i was still wrong. not sure what i was thinking there...
if it's running then it's east to tell ( even someone like me can figure it out LOL )
raise the rpm's ... dump the clutch... if only one black streak, no LSD... if two black streaks, then LSD ....

I would respectfully ignore his advice.
If it's a clutch or viscous coupling, jack the car and put it in neutral. Spin one wheel by hand and note the direction of the opposite wheel.
Open differential wheels spin in opposite directions during this test.
Limited slip differential wheels spin in the same direction during this test.
I'm not sure about helical differentials. Better ask someone who has experience with these. The thing is, most (if not all?) Honda factory limited slips are helical.

This. However, no CRX in this country ever came with a factory LSD, so if it does have one, it's either been swapped or it's an aftermarket unit, in which it could be any type.
I do get two black streaks. 
When the front of the car is raised the wheels turn in opposite directions when I spin one. HMM..

Torsion or helical diffs will allow the wheels to spin in opposite directions like an open diff will.
In reply to porksboy:
These cars will often spin both front tires if you are pointed straight and on a level surface. But they still have an open diff.
