Default H23 - Clutch Pedal Pressure Increases?

Hey guys, I searched for this issue but couldn't find anything similar so hopefully someone can help me out.

92 Accord with a H23 swap done a few weeks ago. Using a brand new "stage 1" clutch from somebody (forgot who).

The issue is that after ~20 minutes of mix road/highway driving, the clutch pedal pressure increases, a lot. The engagement point also moves from about the middle of the pedal to the very top. I can just tap it and I can put it into gear. Neat huh? If I continue driving the pedal pressure continues to increase to "omg racecar" level and things get weird. It'll be in gear and if it's given more than 10% throttle the car with stutter/chatter extremely bad. I've been lucky the few times this has happened and been able to limp the car slowly home.

I've replaced the clutch slave cylinder and have bled the system a few separate times. The issue is still there and my girlfriend is getting tired of helping me bleed the system.

What is going on here? Any help is greatly appreciated.

Can you expand a little further? Could it be an installation issue? I've never had this problem before with a car.

Can you explain how that would cause the issue? I'm not really a transmission sort of guy beyond being able to drive a car with one it.

Down to learn though. Would love to figure this thing out because I barely made it home from work today.

Ur clutch pedal engagement is directly related to the pressure plate position and fork that sits against it .. So if the pressure plate backs off the engagement releases higher ... If it backs off enough u won't get any power to the wheels and it'll make **** load of noise like the trans is falling apart

Just youtube how a pressure plate works and visualize that the next time u bleed the clutch
