just bought a turbo 97 prelude with a p2u5 transmission i asked the guy if it had lsd I think he said no but he wasnt the one who built it his friend did, I got the front end off the ground and both wheels spin same direction that would mean it for sure has lsd right?

 

U can see through a lsd. Both tires will spin when off the ground on non lsd idk why something about the pressure and fluid transferring

 

It's a non lsd f22a6 trany out of an accord. Very long gears

 

The picture above IS a LSD... the narrow holed washer in the middle allows one to "see through" the differential... from one side to the other. A non-LSD differential would have a bar visible across the middle of the diff. about where the washer is in the pic... obstructing the view directly through the middle of the axle opening. Not sure what the gear set is... I'll take your word for that one.

 

He's absolutely wright I apologize.
