I have a 91 LS; I want to know if i can put the LSD outta my y1 into my stock ys1 tranny...they are both cable

 

?

 

No, it won't.

 

does anyone else now....it seems to me if you can interchange the gears from a ys1 to a y1 and vise verse; why couldnt ou change the lsd?

 

No, you can not. I forgot exactly why, but I am pretty sure that you can not.

There are a few major differences (asides from gearing) between the ys1, and the other b-series cable trannies.

 

err ok...

 

Try posting on g2ic.com, I am sure you can get a more defineate answer there. I am sorry I am not of more help. I just remember reading/hearing it somewhere...

 

I found out why... after some quick research. The Y1 LSD is welded to the Y1 final drive, so it would defeat the whole pupose of having a YS1.

 

Different diff & shaft sizes. But you can modify & shim an ITR LSD diff into a YS1, but it's still a good amount of work, but it's been done.

 

its possibly; i posted it on g2ic.com here is the post

"the gears are not interchangable. but you can put the lsd diff from a y1 into a ys1 as long as you change the counter shaft to a 4:26 final. being that the 89-91 y1 trans only came with a 4:26 and the ys1 came with a 4:40."

Which is what I said, although I may have been wrong about it being welded... It would be pointless. Your YS1 would no longer have the hot gearing of the YS1... which would make having a YS1 pointless, IMO.

I am not sure which YS-1 you have, but as far as I know the non-GSR model has got the 4.266:1 final drive, same as the 90-91 integra transmission. Maybe that's what you were referring to.

Yup, I have an ITR LSD in my YS1

what exactly did you have to do to make that fit?

 

A freind of mine builds transmissions. I purchased the LSD and a DC2 4.40 ring gear and sent it to him.

Please note that if you intend to use an LSD meant for the DC2 or ITR, you need to use a DC2 or ITR ring gear. The YS1 and 99+ Civic Si ones are too small.

 

alright, thanks a lot
