Default How much Horspower and Torque can a stock 2.5rs clutch, tranny, and diff hold?

so I have a 2000 2.5 rs coupe. I have turbocharged it and have it running 3 lbs right now just to get it running well. im hoping to turn it up to about 5 or 6 and wondering if my clutch/tranny/diff will hold this. anyone know what the limits are for these parts?

stock clutch is good for 8-10psi, trans is prorated based on power. 400hp, you get about 5k miles, 300hp might go 20k miles. Havent broken an R160 yet but they should only break if you upgrade trans and launch it.

What do you mean by the clutch can handle 5 to 10?

The transmission life span is based entirely on how you drive. Normal shifting will increase its life span while flat footing each shift will end you up in the sub 10k mile range, mine lasted 8k of everyday aggressive shifting at 200ish horsepower to the wheels.
