    Has anyone tried using a hydraulic throwout bearing on their 300ZX? Just wondering what peoples experiences are with them and any issues?

    you might have to expand on this. you are talking about the clutch throw out bearing ? if so, they are already part of a hydraulic clutch system

    a hydraulic throwout bearing doesn't use

    a slave cylinder to move a clutch fork. Instead it has the hydraulic line from the master cylinder go straight to a special piston style throwout bearing and hence you don't need a clutch fork. Sort of like this:

    Is it right to say that in the picture the bleed nipple would require the gearbox to be split from the flywheel / clutch so it could be bled ? Looks good but would be a pain in the arse if that's what is required to bleed.

    Have helped a mate fit one to an improved production race car (KE25 Corolla 3S BEAMS turbo and celica gearbox). Bit of a pain when R&R gearbox and not many kms since install as a cracked block has parked the car for a while.

    I have one fitted on my race car, 4speed dog box. You would have to modify the gearbox to allow slave to be screwed onto sleeve around gearbox input/drive shaft.. Its a lot of time effort and money to replace something that has been working adequately for over 25 years.

    ok so a concentric slave cylinder.

    the big question is , Why ?

    The real answer is everyone seems to think they have a better way of doing things :D
