Ok, just realized we are talking on you other thread. Factory turbo or expensive banks kit is not the answer.
Way better turbo options for less. Lets solve the not moving problem first. If it is a
Rear end l, transfer case, brake problem- you might have more power than you know- haha.
Food for thought until then-
A good stall converter and ATT turbo will make a big improvement and save you more fuel towing.
maybe the hx35/40 hybrid or hx40wii is more your needs. Getting proper exhaust pipe and better incoming air helps after the turbo-
Depending where you live, there may be someone with a proper set up 6.2/6.5 to show you what they are actually capable of.
6.2 to stock turbo 6.5 is an ok improvement. Not as big as 6.5 turbo to a 6.5 proper sized turbo.
Gm turbo (banks is tiny bit bigger, not much) is what all the honda guys buy for the little 2 liter engines.
A stock hx35 is still too small, and that is built for a stock,
Lower rpm 5.9 liter- so wanting higher rpm and another 1/3- 1/2 liter yeah. Think how huge the duramax turbos are in comparison- that is a 6.6....
Doubling your hp takes a rebuilt engine. But 100 hp doesnt.
If you do end up swapping- please sell the 6.2 here- folks need engines!
Heck, maybe a new to you dmax pickup- I might need a 6.2 suburban...
