O.K. this is really starting to **** me off I'm trying to order a new clutch for my B16 YS-1 LSD trans. I have mic.ed the input shaft and it come up as 1". Now I counted the splines on the shaft and counted 24. I hear if you have a 1" shaft it's 90'-91' and if it's 1 1/2" shaft it's 92' + integra clutch. Here's the F***ed part. I have a friend at a shop he has three transmissions at his shop. A S1 out of a 90' integra , a YS-1 from a B16 and a 95 ' GS-R trans. He mic.ed all three shafts and they came up with the same numbers and all three trans have 24 splines. WTF ? My friend has the same motor trans. I do it's a OBD1 B16 with a cable trans and he used a 92'-93' teg. clutch and he said it worked fine. This makes no sense that there different trans that are three different years all have the same mesurments. What car do I get my stupid clutch for ? Thanks

 

I would order a clutch for the OEM car that the tranny came out of.

There's a huge chance that I don't know what I'm talking about, but I hope it helps.

 

Dude I wish it was that simple. My B16 is a OBD1 with a cable LSD YS-1 Trans out of a integra XS-i.

 

Xsi is same as 92-93 Gsr isnt it?

try calling like ACT or another big name clutch place and see what they say.

you might be able to tell them shaft diameter and # of splines and bingo clutch for u>?

 

tried and they're telling to go by messurements but it's all kind of screwed up since my friends mesurement are the same as mine and his 92' teg. clutch works when if going by mesurements it should need a 90' teg. clutch. Here's what I';m doing... I'm going to pep boys tomorrow asking for a 90' integra and a 93' integra clutch kits. Take the stock one out of my trans up there with me. Compare it to the two and which ever ones is a match is what I'll get. Just pretend like you're gonna buy it and at the end just say " Nah changed my mind and walked out " this should work.

 

90-91 has the small 'shaft'.....hehehehe
92+ has the bigger shaft.

If you can determine the year of the tranny, your set.

Your 'Pep Boys' buy both idea seems like a good way to go here.

I never mic'd mine, but its not a 1/2" diff. ,maybe 2mm at the most.

 

O.K. found out 92'-92' works on my trans also I found something else out. Didn't the YS-1 trans not some out till 92' anyway ? either way I had two clutchs and the one for a 92'-93' works fine.

 

You Know I didnt think of that...
