After 5spd swap woes... clutch related I think??
Well the swap went okay, and I am currently at around 300 miles on the break in, but the clutch is giving some issues.
It seems like as soon as I drive for more than 30 minutes or so the clutch will start slipping in all gears after 2500 rpm's. I haven't taken the car about 3500 rpm's during the break in at all. I am a decent manual driver and I don't ride the clutch at all, in fact I have yet to smell the clutch burn at all yet.
The only thing that I have been told could possibly be the issue is that the flywheel wasn't resurfaced when the clutch was swapped to a new one. And to let you know the clutch is a spec stage II 400 whp rated clutch. The flywheel was hardly grooved at all if any at all when swapped, we didn't sand or resurface because we didn't think it was a big deal.
All work was done at Nissan with a certified mechanic. I am 99% positive the clutch was put on in the right direction and it was all aligned. It just seems that if the clutch gets hot that it will slip at 3000 rpms and will barely grab if at all in 4th or 5th gear. Slips through 1st, 2nd and 3rd and gets progressively worse through each gear.
Any help would be great, I am trying to find any possible issues that could be attributed to this being that I am new at the whole 5spd thing.

that happened to me at one point too when i took a trip down to a junkyard far south jersey to get my ECU. I think bleeding the clutch solves that problem? maybe u got gases in your brake line?

I thought I read here a while back of someone's manual conversion
having a slipping clutch problem due to the place where the clutch
master cylinder mounts to the firewall being slightly different on
an auto. At any rate, the trouble was due to some pressure on the
master cylinder piston causing the clutch to be partially disengaged.
The fix was to use a spacer or something. Anyone else remember this?

I remember reading that post a while back. Sounds like your clutch master cylinder isn't releasing all the way and you still have some pressure on the slave cylinder. Is your release point very high when this is happening? Thats a sure sign.
Figure out what spacers you need and get them installed.

I have discarded anything to do with the flywheel and clutch right now.
Thanks for all your help and it should be resolved tonight hopefully.

It is releasing really high, and we are going to try and adjust the bolt today to compensate for the slight difference in height from stock spacers to the spacers I am currently using now. You can't buy the stock spacers and put them in because they are actually epoxied to the firewall or something crazy. But nonetheless we are going to compensate for the space by adjusting the bolt in further or by putting in different spacers.

Looks like it was in fact the clutch rod going into the master cylinder, it was adjusted today to compensate for shorter than stock spacers. Felt really good on the way home and I could floor it in 5th at 40mph without slipping.
Thanks for all the help and I will delete this later.
I sure do have a lot of chatter in reverse, just a hard clutch i guess.
