Help me with some recent confusion plz!

Alright well I just recently got rid of one of my vehicles and have some money to put towards fixing my supra. Not a lot mind you, but enough to get it going and hopefully acquire most of the parts towards a 6 speed conversion. Some of ya'll may remember it from a couple of months ago. It is a 97 yellow NA auto and is hit pretty hard in the front end.

Well I was thinking earlier about the rearend (cause I am wanting to convert to 6 speed) and this is where I got confused. Why do people buy the whole pumpkin from a 6 speed car when converting to a 6 speed? Is it because they want they gearing AND the lsd? Or is it some other reason completely?

Reason I ask is because if your car already came equipped with an lsd, couldnt you just buy the 3.13 ring and pinion gear and install it in say, a 97 NA auto supra and have the same thing as the entire pumpkin from a TT rearend? Or is it more complicated than just the ring and pinion?

I ask because my budget is kind of tight and if I can just get the ring and pinion instead of the entire pumpkin and have the SAME thing as the entire pumpkin swap, then I would rather do that so I could put the saved money towards something else. Either way I do not want the 4.27 auto gearing once I go to 6 speed because I can only imagine how useless 1st and 2nd gear would be and how many rpm's I would be turning at highway speeds.

And on that note, does anybody go to a 6speed swap and still use the stock NA auto rearend and gearing? Like if they don't have enough money for a 6speed pumpkin at the time? Also if they do, what drive shaft do they use?

Sorry for such and long post and if I have confused anybody.

i've also been wanting to know that. this way you don't have to change the axle either.
i'm sure you can use the stock rear end with the NA gears but they will be wayyy too tall, and as for the drive shaft, i know for a auto you have to swap it out with a 6 speed because the 6 is a shorter trans. but you can get away with reusing the auto one but it will be extended out pretty far. check out
hope that helped.
That did help on one part, so I am gonna bump it back up in hopes of someone chiming in on the ring and pinion question. Hopefully me and you both could get the answer we are looking for.
