Ok so I need some help figuring out what the hell is wrong with my clutch. First off I have a JDM 4.44 STI 5 speed w/ rear diff mounted to an 03 wrx block. When I made the switch I put in a brand new stock clutch and flywheel.

I broke the clutch in nice and easy, and don't have any problems driving the car around town at a moderate pace. The problem is that whenever I punch it WOT, as soon as I go to shift before redline the clutch feels like it sticks to the floor and will engage almost instantly or not at all. It will shift fine below 5k, but anything with a full load sucks it to the floor.

Any help is much appreciated as this sucks....also if anyone wants to go for a ride to see what I am talking about let me know.
