Just quick question, I snapped the old one in the stock transmission, what exactly is it? a chain? is it common in boosted GAs? just pullin the old trans apart

Not a chain. Its an actual band.

Follow the link and scroll down partway for an illustration.

why would it break(the one that wraps around the gears?)

Stress? As the band tries to engage around the shaft friction is created and therefore heat. Enough heat weakens the band and over time it stretches until one day it says enough and breaks.

I broke bunch in my S10 and had to rebuild it twice and then got fed up and got the GA. The harder you are on the trans the more problems you will have. Being boosted is not helping in your particular case. Id look into companies that can get you some stronger bands rather than using stock components.
