So I'm working on a nice little swap for my FB which uses a TII transmission.

I have managed to shorten the shift rod/swap in the FB shifter housing, fab myself a trans mount, and get the engine and TII trans all mounted in my FB already!!

Everything has gone perfect so far, but now I just need to figure out what to do with the clutch hydraulics!!

After doing a bit of research, it seems that the FB clutch hydraulics have a 15/16" bore while the TII hydraulics have a 3/4" bore.

I have read that most people seem to use an FB clutch master with the TII slave,
but that brings me to my question:

Wouldn't the FB master move more fluid than the FC clutch master? Or is there a difference in stroke length between the two generations?

If the FB master does move more fluid, is this going to cause any problems down the line?

The reason I ask this is because I dont want to cut any corners here, and it seems like the best setup would include properly matched components.

Is there any reason not to use both the FB clutch and master, and perhaps just the TII pushrod if the distance to the clutch fork is different?

Has anyone successfully put the TII clutch master in their FB?

And finally: for those of you who are running the TII trans in your FB, How did you go about this? and how is it working for you??

Thanks,
Alex

 

I've got a Series 5 box in mine and am just using a Series 5 slave with the original FB master-had no problems whatsoever.

 

^Same, S5 trans with S5 T2 slave cyl and the FB master cylinder. No problems at all and its been in there for years and thousands of miles.
I'm sure the FC master would fit in there easy enough as they are very similar, but theres really no need.

 

Same as them. I used the FC hose, too. It fit a little better than the FB one.

 

Thanks for the info fellas.

Guess thats what Ill do as well!

 

The FB slave is actually different where the bolt holes are.

On the T2 they are quite forward near the dust boot, on the FB they are nearer the middle.

T2 slave and FB master all the way.

 

FC master won't fit a 1st gen man!

 

Maybe with a custom/remote reservoir... Really not something I want to mess with unless it is imperative!








Since there is apparently no need:

 

You'll find the studs are at a 45 degree angle. But there's no need. Celebrate good times! (couldn't find a smilie I liked for this)
