Hey, I have a 90 Crx I just finished swapping a turbo LS Vtec into. It originally had a 93 LS trans, but since the car had been converted to hydro I had an M factory lsd and my gearsets swapped into a 94 hydro LS case.
I finally finished the project and the clutch will not disengage.
I bled the slave cylinder very well. It pushes the shift fork back as far as it can, so it seems to be operating correctly.
I can see the fins on the pressure plate pressing in pretty far through the shift fork hole. But if I turn the car over with the clutch in, it bumps the whole car forward aggressively. It does not feel like the clutch has any slip like it should if it was even remotely disengaging.
The clutch/pressure plate/flywheel is from a 92-93 integra. I read that they are all the same after 92 correct?
Throw out bearing is from a 94 LS to match the case.
I torqued the pressure plate in steps to 19 ft lbs. So that shouldn't be lose.

Does anyone have any other suggestions I can try? Everything is in nearly perfect shape and installed correctly.

 

Maybe if the splines on the input shaft were not lubricated well, the friction disc is sticking against the flywheel and is not able to slide away from it, so even though the pressure plate is releasing, the disc is still dragging?
I take it if you start the car in neutral it will not bump forward - hopefully?

 

I actually found my problem after some more research. It turns out the throw out bearing is overextending the pressure plate into the clutch causing it all to stay bound up. If I push the clutch half way in it shifts normal. So I just need to adjust my clutch or put a block behind the petal to restrict full movement.
thanks for your response!
