s14 clutch slipping ---weird---

[jspeedm]

OK, so this seems completely backwards to me. I have a pretty stock KADE with a Nismo flywheel, 1st, 2nd, and 3rd pull strong, but 4th and 5th slip at anything over 3/4 throttle between 4-6k rpms.
any ideas?

that does seem weird, i'd check the simple things first like clutch pedal end play..i think an inch and a half is normal

even then, it would normally slip in the lower gears.
