I have two 240z, one the clutch pedal is nice and soft when pressed to change gear. The other 240z, the clutch pedal is hard to press, I already changed new clutch master and slave cylinders. The transmission is a 5 speed from 280z with unknown clutch. Do you know why the pedal is hard to press? Is it because it might have a performance clutch so stiffer spring? It is almost a chore to drive. Any advice and input greatly appreciated.

If you have changed the slave and master and they are the same as the other, its most probably different pressure plates causing the hard clutch pedal.

Sometimes the throw out bearing collar can seize up on the guide when the grease dries out. You can easily check that by checking the clutch fork for free play. You might need to take the sale off to check for movement. If it moves freely its not the problem.

Check the clutch pedal pivot points moving freely.

thanks eurodat. The pedal is a little hard from the high performance clutch. getting used to it and it's actually pretty fun and solid

I want a stronger clutch. Which one did you use?

I use a lightened flywheel out of the 280ZX with a new clutch and pressure plate. It feels the same, maybe a little harder, but it has a lot more grip. The clutch is 240mm instead of 225mm! Which is about 40% more grip than the original.

I was thinking of going to a stage one, but I like the feel of the original, so I opted for that route and I am happy with the results.

So you've got a 240mm flywheel? I have a 225mm Tilton aluminium that was part of the deal on the 240Z I bought. I am going to put it on my 280 though and have read that a Nissan clutch was about as good as I can get besides some kind of racing clutch. You're happy with yours, that means something to me, thanks.
