Yep , its slipping the God Damn clutch AGAIN...... , after all my previous clutch problems I aquired a slightly used OS clutch , I had to resurface it , the machinist only taking off .002" though . I bought brand new discs and plates for it , installed everything and now it slipping when I am in second gear from about 6000k rpm (when the bridges get pumpin) and still at only 10psi of boost !!!! and rich a/f ratioc ( i have to retune after the '044 installations). Seems like I wo'nt ever get to tune to 20 +psi of boost.

How tight did you torque the bolts which hold in the plates? I believe the tighter they are, the more they hold.

There aren't any bolts to hold in the plates , the plates go between the discs and they are all fit into the "cage" , the pressure plate is then bolted on using the supplied allen bolts, no space is left everything goes together very tightly.

Which OS is it? the B type or the C type? measure the discs as well, they should be around 4.3mm new.

Just a thought.

Was the slave cylinder hard to reinstall? Some times with these clutches, the angle of the clutch fork is changed. I had to cut a 1/4 inch off the slave cylinder rod to compensate for this angle change. You should be able to reach down and move the clutch fork by hand. If there is no movement then try shortening the slave cylinder rod.
