sututututu

I just got an aristo transmission for my gs300 and I want to know what I can do to get it to withstand some extra torque so it does go out on me when I run a turbo.

I got a cooler for it and I'm gonna do some things to the valve body like gaskets etc. and as well as a shift kit. also considering increasing the stall on the converter but I would like to hear some opinions.

My car is running a 100 shot of nitrous wet until I decide to turbo it. I'ts sort of a daily but its mostly for when I go on trips every now and then.
