Need some T56 tranny advice

[sciff5]

Looking to do something with my tranny this winter. When I got the car it shifted fantastic with the stock clutch. The first time I drove the car I was quick shifting it because it was so comfortable. (first of all I never owned a manual car before so although I could drive stick it was still pretty rough. Ask don it took me a couple times to get it on the trailer the first time I brought it to his shop)

After I put the oz700 clutch in I never could get that feel again. and the clutch barely disengages. I just dont think the hydraulic system in the rx7 is either not functioning properly or dont have the capability. It disengages the clutch at the floor and quick shifting it is a damn chore. I think this is mostly the clutch and hydraulics, although the tranny when cold is clunky and it wont go into reverse no matter how hard you try. Once it warms up though I can get it in reverse and it shifts fine. So I dont think if it was really a transmission issue it being warm wouldent effect it. Anyway this winter I'm going to rebuild the tranny.

heres the 2 scenarios I need help with
First of all I need to figure out if I should just get a basic rebuild or step up to a tick stage 2 rebuild (I really dont want to spend the money right now and I dont see myself doing much drag racing next season because I dont really have a class to race in) So I dont think I need the stage 2 now. It seems that drag racing is just way more abusive than other forms of racing and thus so far more expensive. Autox and road racing may have a higher cost of entry but they usually only eat wear items like tires and brakes.

And the second scenario is that I can buy a t56 that needs a rebuild for 500$
Here is the sellers description

"I have a 00 T-56 trans out of a Camaro, it comes with the bellhousing, slave cyl. and stock shifter. Everything in the trans is good besides the 2nd gear syncros. You can spin the input shaft and the output shaft turns as normal in all gears including reverse besides 2nd gear. When it was in the Camaro 2nd would grind and not go in. I will take some pictures later this week. I would prefer pickup but I go to PA every few months so I may be able to meet up with someone. I could put the trans on a pallet and ship it out to anyone. Please send me a zip for a shipping quote.
"

I am highly thinking about picking up this tranny because I can prob sell my current unit for at leask 1000$ seeing as it does have under 25K miles on it.
And get this tranny rebuilt and prob have a rebuilt tranny for little money, but the risk is not being able to sell my current tranny, and i dont know how bad this unit needs to be rebuilt. The advantage is that I could save hundreds of dollars. I think I should be able to move the current tranny though as I could let people try the tranny before I pull it, and have don rebuild the other tranny at the same time. Then when I sell the one in the car, swap in the rebuilt unit. Most likely with a stage 3 monster but I'm really affraid the monster will have the same shitty low engagement/disengagement point. The stock clutches seem to be really high allowing you to just tap the clutch to get into the next gear.. Shouldent a high performance clutch be this way too but I've never run into one like that. Wtf gives?
