Slave Cyl Question. Difference between E21 & 02?

Is there a different in bore or piston size? Before my 5-spd conversion the clutch engaged about 1/2 to 2/3 of the way down. Now, after the 5-spd conversion, (same clutch, flywheel & PP) the pedal needs to be ON THE FLOOR to engage the clutch completely. The release seems better but depressing seems like i'm almost not pushing enough fluid into the slave?? Is that possible?

I'd bleed it again. I've never had an issue using the '02 master with the e21 slave.

bled it twice now... even using the super blue good stuff....

Could it possibly be that I'm using a funky (Aardvark's) hose between the master and slave? I think it's to a 5 or something.... Maybe I should go get Ireland's braided SS one?

It's just a PITA and I feel like I can't drive cause all I do is grind gears...

How long ago did you bleed it? I doubt the hose makes a diffrece.I would however recheck the torque on the fittings. If one's loose it will let air into the system.

torque on the fittings is fine. There's NO air in the system. Every time I've changed/bled I've changed from blue to gold fluid and I start with the clutch, then go in order with the brakes. Not once has a bubble of air come out. It's like I need to move the pedal up more or something??? Just not sure but it wasn't like this before. It's not getting worse either so at least that's good...

It's all different-

the cylinder might be the same diameter (never measured), but the mechanical leverage ratio for the throwout arm is quite different.

In the 3 cars I've converted, all three had a longer pedal and lighter feel-

I always assumed that meant that the effective leverage ratio of the 5- speed was a lot higher, i.e. it takes a LOT of fluid to dis/engage the clutch on the 5 as opposed to the 2002 4. Just like the early linkage on a 5spd will give you a short shifter...

Have you ever done anything to fix this? I don't like the feel AND one of my goals was to get the car into a condition that the fiance can drive it. Now it's almost worse than before because of the difficulty engaging gears. Is there a larger volume Master cyl. that could be fitted? OR possibly a way to adjust pedal travel so that I start depressing higher?

TIA,
