In a straight line, G80's aren't bad; I have read of people running them into the low 12's with 100k miles already on them without a hiccup. But act like a dumbass and do donuts and hang the back end out around corners, and even a stock engine will bust one.

im running 4:56's with a stock g80, but with your setup it's only a matter of time before 
save yourself some time and heartache, buy a tru-trac

well if you want to put the gears in, then just drive it really careful. then when you have the money buy the truc-trac. the g80 should hold as long as you baby it.

If you are going to install everything yourself, go for it. But if you are going to have the gears and TrueTrac later both professionally installed, save yourself double the installation cost and down time and put the gears on the shelf and save up for the truetrac. Just my $.02

You should be able to floor it and run it out hard, but just as TX Tahoe Z71 said, if you abuse it, it will break. One of the items that is hard on them in my mind (according to how they function) is actually heating up the tires doing a burnout, the unit is locked and then all of a sudden when it gets up to X mph the counterweights unlock it, which happens to be at or close to full throttle, it has to be one hell of a shock load. My G80 lasted for about 8 years, but I'm AWD so it was under a shared load, but once it got to where I was spinning all 4 it shattered fairly quickly.
