Clutch Not Disengaging! Bad bleeding or bad pressure plate?

[dongoesby]

Solving problems after another one came up for my SR swap, this is pretty frustrating since this clutch disengagement issue is the last one preventing me from getting the car on the road.

Search after search, I ending getting Illegal Garage custom dual diaphragm clutch.




Situation: searched and went through FSM for proper installtion. Pilot bushing, throwout bearing and pivot fork (and clips) should have all installed correctly. During the swap, I didn't disconnect the perfect working stock slave cylinder, so I used it with the SR tranny and new IG clutch and I could not fully disengage clutch. With the engine off, I can shift into all gears; with the engine on, I can only force into 1st and 2nd gear. And the rear wheels start to spin before I actually shift into gear.

#1 try: I swapped to Nismo slave cylinder, took out damper box, connected directly from master to slave with braided line; and bleeded. Same behavior, only able to force into 1st and 2nd gear.

#2 try: I went through a proper bleeding procedure. Took out clutch pedal stopper bolt; adjusted the pushin rod to the highet; then bleeded. The nismo slave had a great amount of leverage (almost like stock one). But samething. Only able to force into first and second gear.


#3 try: I shortened the pushing rod to the lowest point, and the pedal suddenly went out of pressure. So I bleeded it again and found a lot of air bubble while stepping with short pushing rod. With short pushing rod, the slave had less leverag
