this noise seems to be rpm affected, the rubbing sound seem to rub quicker when i rev it in neutral. when i push in my clutch it goes away. as soon as i release my clutch in first, the rubbing comes back.
Since its affected by rps in neutral shouldnt that indicate the clutch/flywheel assembly area? or could it be comming from the transmission as well?

It could be anywhere from the flywheel to the back end of the counter shaft. Odds are good that it's in the clutch area though. A common issue I've seen with noises that act how you describe is a shot pilot bearing.

When you push in the clutch pedal, that's when the input shaft is turning in the pilot bearing. When you're off the clutch pedal, the clutch locks the input shaft to crankshaft / flywheel speed, so the pilot bearing isn't doing anything then. Since you say it happens when you release the clutch, I'd say it's probably the release bearing.

I did my clutch i while back, and replaced about everything. New clutch, flywheel, pilot bearing, throwout bearing, slave, and master. The thing is though, I took the throwout bearing that came with the slave off and put the one that came with the clutch, as it spun more freely and looked more like the older one. Possible culprit? or would that not matter?

Hard telling. Did you put grease on the outside of the release bearing where it rides on the clutch fingers?

I didn't. My book said it didn't need further lubrication.

If the pilot's inner race has come apart and allowed the needles to go everywhere you may hear noise with the clutch out. The input shaft's nose will spin and turn against the needles now that they aren't held to the outer race by anything.
