possy rear end?
i just started my project car and right now i have a 1990 240sx fastback with a redtop sr20, and i still have a one wheel peal..i want a possy rear end..or semie possy, but im a little low in the money right now after the sr20... but my teacher said there is a peice that costs $50 and u put it inside the diff on the drifshaft, and it connects to both gears ans spines both tiers...i was just wondering what you guys did or if enybody did that tell me how it is? im always open to new ideas and i don't want to weld it, im afraid of somthing snapping and i doent really want to hop around sharp turns... thx guys

Ugh.
Welcome aboard.
First off: POSI, not possy. And that's an old-school term that's not used for imports.
Second, you have an "open diff". One-wheel drive, in essence.
Third, there are many different configurations of rear differentials: 2-way, 1.5-way, Helical, Viscous, welded, and so on.
Your teacher is about as confused as can be. Perhaps he'd care to pop in and educate us on this "$50 piece".
If you don't want the locking that occurs with a welded diff, you have 2 choices: VLSD or HLSD.
I recommend a VLSD from a J30 - make sure you grab the axles too, you'll need them.

I think the teacher is refering to a Phantom Grip style of locker. I was considering buying one, but I could find no real info on real world applications.Similar devices have been used on muscle cars, though again, info is sparse. If anybody is using one, they sure as hell don't want to admit it.That said, I would lean more towards the helical than a viscous. As far as maintenance and general life span go, it would be superior to a viscous coupling. I know I could strip several years of service life in a stock viscous diff in about 15 minutes. But then, consider your driving style, tire size, and suspension, general goals for the car and make your choice accordingly. You may just be better served by a viscous or clutch type unit instead.
