was just wondering if i could use the clutch out of a FB(1985), in a 1980 SA? or would i have to swap trans... i know the trans is a slight bit different and would require more effort in getting it it.

 

They're all single dry plate, diaphragm spring, hydraulically operated clutches, though the 84-85 tranny is different

 

the bell housing from my old S1 engine wouldnt fit on the S3 engine i got now..
the S3 engine has a lighter flywheel (i think) and the clutch is resseed into it alot more..

the clutch i think was a little smaller in dameter too, but it still works.

and im pretty sure the tranny will still work, but dont quote me on that one.

 

NO!

the 79-82?? motors have the 215mm clutch and very little dish on the flywheel, the 83-85 have the 225mm clutch and a much deeper dish on the flywheel. I ran into this problem when putting a 83 motor into my car when i went to swap the clutch over... no deal.

 

so it wont work if i take the clutch out of the 85 and put it in my 80? just makin sure... its not any bit possible and even if it did work would it slip or grab early?

 

Nope.. won't work.. two different sized clutches... would have to swap flywheels..

so would i be able to swap the flywheel and clutch out of the FB and into my SA without any problems? and are there any weight diffs between the fb flywheel and the Sa flywheel
?

 

You need to know if they changed the rotor weights and therefore, the flywheel weights between 1980 and 1985. I think they did.
