Gonna replace the clutch before winter.. Seems to be very high on the pedal and not in the middle or bottom of the pedal. Is this normal or is it time. just seeking advice and what stage or what people are using. I was thinking a 6puk stage 3 and "racing flywheel" cause after she's paid off in going to TT the N/A.

Sounds to me that you need to adjust the clutch pedal, and only if that fails should you assume that your disk is done.
For replacement you will want to stay with the OEM organic clutch, or at worst another organic clutch such as Exedy. Even if you get a lighter flywheel stay with organic as the 6-pucks are not good for service life nor driveability, especially the "racing clutches".

Oh ok. What about. The 3 puk or 4?? Cause I will eventually be twining up with a goal of 400-475 rwhp at said boost setting and will be turned down for winter.

When I did my work I did everything to be able to handle well over my intended power goals, which was about 450 max and similar torque. I've since settled in the 400 range and am happy for now, still needs some tweaking but at 90+% I feel.
My Z guy said, and has held true so far, that an upgraded organic disk is good well into the 600 range for holding power, and will feel and work best for the street (closest to stock feel- a LITTLE heavier and more feel IMO) when combined with a heavier duty pressure plate. I LOVE my setup, and lose nothing when launching hard and shifting fast so he seems to have known what he was talking about.
The puck configurations have less surface hold and due to their design, do not have uniform surface to engage with the pressure plate which can cause notchiness and chatter, and a harsh feel when engaging to take off in a normal driving mode- so if that doesn't bother you as well as shorter life, go for the puck clutches.
The main gains from these clutches is lighter weight and unique substances used for the pucks, all mostly good for the "cool factor" and little else outside of a race car...

Oh ok. So I eventually want to. Swap a TT or rebuild for a TT I'm aiming for 450-475ish rwhp. I'd would need a clutch for 600+??

I would go for a stock clutch, or an aftermarket organic as DCaff suggested. I went with a Luk Pro Gold and am waiting to install it to see how I like it, but he is right, the 6 separate pads aren't much fun for daily driving. A good friend of mine has a nasty stack of tickets from his Racing spec clutch in his 240sx. Every time he leaves a stop light he has to rev up to a pretty decent rpm (usually between 2k and 3k rpms), and then pretty much drops the clutch in order for it to get a good grab on his lightweight flywheel and he jerks up to 20mph in half a second, usually squeeling the tires, no matter how hard he tries to play nice with his clutch pedal. Unless you are building a serious racing machine, I would stick with something similar to OEM. My clutch is only slightly lighter than the stock 300zx clutch, and it has the same shape, depth and density of ceramic on it to give it a stock feel. Again, I have yet to try it out, but I have high hopes.

A good heavy duty pressure plate able to handle 5-600HP and a high quality upgraded organic clucth will have you where you want to be with a street car, anything more and you better be drag racing it for what little it will make things better, and make the worse areas such as engaging and taking off negligible under the circumstances...it's what those clutches generally were made for: lighter weight and hard quick grab.

Personally I don't find that much entertainment from straight line races, more along the lines of drift or road course races. But what brand would be good? And what weight flywheel for good throttle response

NA and TT clutches are different, not sure if it was mentioned.

I'm aware. TT clutchs are bigger in diameter. Still can't make up mind weather I want to boost or not but. So far I've just bled it and its alot better.
