Ok so Ive decided on wat im goin to actually do with my CA so far I have the fmic, 255 fuel pump, z32 maf, afc neo, and a couple of other things. I wanna know which lsd is better 1.5, 2, or a j30 or z32. Also my car is a 4lug without abs and I really dont wanna go 5 lug.

Taken from the Drift Forum FAQ: (zerothread/139711)

"Limited Slip differential, connects the two wheels together when they lose traction. With an open diff only one wheel spins, the other is just dragged along. Open differentials are frustrating and boring to drive.

1-way: Connects the wheels together only when you are pressing the gas. If you are off the gas they can move at different speeds.

1.5-way: Connects the wheels when you press the gas, but allows more difference in wheel speeds when you aren't pressing the gas. Hence the 1.5 way, connects when on the gas, connects partially when off. This is my personal reccomendation as it always has the wheels connected, but allows them to move more when off the gas so you can get a sharper turn in.

2-way: Connects the wheels when both on and off the gas. Some people like these but i think they create a little too much understeer. if you have a good suspension you can compensate, but you need good car control skills too to keep it under control.

Viscous LSDUses a viscous fluid that essenitally gets more viscous as the wheels turn different speeds. The thickening fluid connects the wheels together. This is okay if your on a budget, and alot of people use them, but most come out of older cars. The fluid in the LSD, like all viscous fluid, looses viscosity over time. Plus these don't hold all that hard to begin with. So get one if your on a budget, otherwise don't bother. Also, these are only 1-way.

Clutch typeThese use clutches to connect the wheels together. These usually lock very soon and very hard, which can create some understeer, but its also good for drifting once you get past that initial understeer. The hard and fast locking keeps both wheels spinning for good drifts. Popular ones are KAAZ and Nismo.

Torque Sensing (Torsen)These are a little more complicated then clutch types. Since they don't use clutches they don't need to be rebuilt. They don't lock as fast or as hard as clutch types, so their usually used more for autocross than drifting, but they work well and don't need as much maintenence. The only company that i know of who makes these is Quaife."

I think a 2nd hand j30 or Viscous would be a descent unexpensive option, but might be limited. Also unless you are doing High Speed Track Drifting every weekend a 2-way might be too much.

Im in the process of ordering a 1.5-way for my daily driven 200sx that might see some drifting and drag activities.

Also, converting from 4 to 5 lugs has nothing to do (AFAIK) with the Differential, or at least as it would when dealing with Brake Upgrades and New Wheels/Rims.

I suggest a 1.5 way. Shouldn't have to do a 5-lug conversion either.

yup u dont need to go five lug, u just need the proper out put shafts and axles,

and if u go z32m make sure its NA, turbo axles are to big

you should report back when you get that installed and running. I too have been wondering what to get.

Wait.... Thats not what we're talking about?

And there are no 240sx's with factory LSD's down here either. I used to have a 180sx diff.
