Re: how much power can 180 & 2oo rear end take

i've always heard that the r180's are fine up to about 300 ft/lbs of torque; and with r200 i've seen turbo cars pushing 500 hp...so with a modest turbo application i'd say you'd be fine but if you plan on making some real horsepower and torque then you would need to swap to an r200.
