If you look I dont think the oem T5 is TQ rated very high.
If I recall correctly it was third or something related to 3rd gear id break, but dont hold me to it.
stock they are rated to 275FT-LBS-325 depending on year, the S-10 T-5 was good for about 325FT-LBS
3rd is what breaks it's the same deal as the A833's the main shaft spreads away from the Cluster losing teeth engagement.. except the A833 does it at about 200FT-lbs more.
If your dead set on a T-5
https://astroperformance.com/ can build you a 600FT-lbs T-5 for about 3K and
http://www.pro-forceperformance.com/ can do 450 FT-lbs for about 2500,
