Detail: I have a 93 nissan 300zx non turbo. The clutch is still slipping when car is hot. I've replaced clutch and pressure plate, slave cylinder and clutch master cylinder. What else could it be??

Goodluck! , did u try bleeding the lines ? if your changed every thing and still have nothing u might just have alot of air in the system , If you have had the flywheel cut, have a clutch with a different release height (different finger or diaphram design & height) or a remanufactured pressure plate, or all of the above, you may run into this problem. Small differences there translate to a large difference at the pedal. On linkage type designs, there were several options including longer/shorter throwout bearing or adjustable fork pivot ball. Hydraulic systems should compensate somewhat, but if you are beyond the travel of the slave cyl, I'm not sure there is anything you can do from the outside. I would check that there are no air leaks. If you have an external slave cylinder you may be able to make a slightly longer rod that connects the slave to the clutch fork. I really can't think of anything else to do at this point. Hope this helps a bit. , Ck for return spring at clutch lever. Check to see if spring pulls back slave cylinder rod by havung someone push the clutch pedal down and release as you watch it function below. Then open bleeder at slave and check for residual pressure. The rod at the master clutch cylinder may be adjustable, shortenten it so the cylinder is fully relealeased with little to no pedal pressure. Good Luck
