Why dont more people run N/A Transmissions?

[hypergenesis]

Well I have been researching a lot into how I can tturn this n/a 6 bolt I have into a good block for my 2g and I came across this thread:

http://www.dsmtuners.com/forums/1g-n-t-tech/55459-4g63-nt-engine-how-make-turbo-kit-12.html

In this thread they state that the N/A transmissions have higher final gears and have better track times. Now im wondering why isn't this done more often? Is there something I am missing to it because I haven't heard of people running N/A transmissions as a normal swap.

If what that thread says is true then you can get a better transmission for a lower amount of money just due to the fact that its N/A.

Please let me know if I am missing something to this.

the NA transmissions use ball bearings which makes them weaker IIRC

also the axles are smaller and weaker IIRC as well

K thank you I knew there had to have been a reason but no one said anything towards the fact that the poster mentioned N/A transmissions were better for 1/4 miles.
