OK I bought a spec stage 3 clutch had my flywheel resurfaced also i did my rear main seal while i was working on that end of the motor. but now i have a major clutch slip under hard acceleration in every gear. i did everything rite this isnt my first clutch job im just at a dead stop with this.

motor
b/t sr20 with a t28 dont think i have the hp to slip this clutch.

can you guys give me some ideas. why is this clutch doing this?

its probably you clutch master cylinder, thats what cause my slippage when i had my new lightweight flywheel and clutch kit put on, or your pedal is too high when you engage the clutch ???

1500 + on the clutch before hard driving.

It doesn't take that many miles to break it in. It also depends if its highway or city driving. I beleive 300-500 is recommended. I live in NYC and with the amount of stop-and-go driving, (and my light flywheel, which forces me to take off from a higher rpm) after 150 miles I would be comfortable thats its broken in.

Just my .02... no receipt needed

i driver 120 miles a day 60 one way then 60 the other for work it's all not stop because its highway driving. when i got the clutch from spec the rep that sold it to me reccomended 1200-1500 on normal driving. i dont use my car other then a D/D and a lil track time like once a year.

i know the clutch is broke in. my ka clutch was broken in at 300miles

thanks no worries..

You've said this twice, but this would have no effect.

The pressure plate WANTS to keep the clutch squeezed against the flywheel.

The only way this is not happening is:

A) wrong pressure plate/clutch
B) not tightened down correctly
C) preloaded the clutch (need to adjust the clutch pedal out some and rebleed).

my bad, well anyways maybe you clutch master is leaking, you should definatley inspect the ruber boot of the cylinder, probably loosing some pressure there to engage the clutch properly
