2.3L ranger differential

[ncsdaonex]

okay, first of all i have a 4 cylinder 2.3L ranger 2wd, i need to now how much hp the stock rear can take, also i might make the rear a lincoln locker because i am going to turbo it and to get all the power to the rear wheels without spinning. now what is the difference between posi and a licoln locker?
but i really need to know how much hp the driveshaft and rear axle can take?

A posi is a limited slip, a "lincoln" locker is like a spool, unable to unlock both tires always moving the same as the other no watter what. A properly welded 7.5 should support upwards of 250HP for street use.

Yup, A posi unit will hold up fine. If you're running low profile tires (Small outer diameter) you won't have to worry about the rear end at all.
With the turbo putting out a lot of boost and larger diameter tires the lincoln locker may become necessary. (the lincoln locker eliminates the weak point).
