clutch problem *grumble*

[kenshinS14sks]

got an auto-manual swap done about 2 weeks ago to a 95 s14. used a s14 ka, with an s13 tranny (fit fine). ever since the swap the clutch has been acting strangely.

when cold, clutch pedal will feel soft with the contact patch low, as clutch/engine get hotter or if driving hard, pedal will get harder to press and contact patch will creep up and upon medium to hard acceleration (in any gear) the clutch will slip, causing engine rev with little acceleration. it beacme almost unbearable so i changed the slave cylinder to a new nismo, bypassed the clutch damper box with earl's braided cable, and got me a new rps clutch. 3 different renowned shops in the so cali all have no idea what my problem may be. the only thing that isn't new is the master cylinder which has been changed out once already. fluid levels are all fine. and air bubbles within the lines do not seem to be a probable cause since the system was bled and refilled when changing the clutch.

any and all help will be greatly appreciated
