I bled the clutch, checked trans oil level, and have been adjusting the MC piston length 'lock nut' on the clutch pedal [only helps a bit]. Grinds on hard accel [4k+ rpm] shifting into 2 and 3, and [here's the kicker] when Im in NEUTRAL, I clutch in and blip the gas and it grinds!? I noticed this when rev matching/downshifting then just tried it in NETUTRAL and it happened... >;(

Im considering your advice, but I hesitate because my oil is stil NEW... any ideas?

The only other thing I can imagine is that the pilot bearing is causing it somehow because the person who installed it said the s13 bearing from my s13 Nissan OEM clutch kit was not a perfect fit for the s14 tranny. It fit after grinding it... is it time for trans rebuild...!? Info/suggestions appreciated.

S14 and s13 pilot bearings are definately different. Probably not the most intelligent thing to just grind down the s13 unit, and cram it in the s14 tranny....
