I have a 97 honda civic ex with a D16Y8 with unname turbo on 9psi. The problem im having is when ever i get above 3000rpms my car acts as if its not in gear. Does this in every gear. I replaced my slave cylinder and it stoped. For a day then started doing it again. It feels as if my tires are spinning but i know there not. Please any information will help or ideas on what it could possibly be.

 

Need more information on what modifications you have. 9 psi is quite a bit on stock internals, if that's the case.

 

Sounds like the clutch is slipping.

 

Mae sure that when no one is pressing the clutch pedal, you can push on the lever and push the piston into the slave cylinder.

If that is the case, there's no problem with the lever holding the clutch in, so the only other possibility is the clutch disk must be worn out. Time to replace the clutch set.
