um, its not loud and unpredictable if it is broken in properly (actually very fun). the 2 way is your best bet just be careful it will slide like a beast, alot easier. i had a kaaz 2way and trd 4.77 gears in my ae86 ant it was beastly, i loved it. im gonna throw a kaaz in my sc sometime soon as well i miss my kaaz ae86! but im glad that money pit is gone LOLOLOLOL

 

kaaz has a 1.5 lsd that im thinkin of gettin. i had driven a sc3 wit the kaaz 1.5 and i liked it, it wasnt too jerky

 

actually it is almost identical. i just got off the phone with a guy at powered by max, (which sell bushing dif reinforcement kits) he said the kit was designed for sorarers and all of them fit except one cuz he said there is a slight difference in the usdm dif housing.

 

so will the kaaz 2 way cause wheel hop or no?

 

Are Cusco LSD's any less noisy than the Kaaz ?

no all clutch types generally sound exactly the same.

 

Wheel hop has nothing to do with the differential, it has to do with a pulsing rhythm of traction/no-traction causing the wheel to bounce or "wheel hop". That annoying action of the rear wheel is solved with stiffer suspension, stiffer bushings, adjustable traction rods, and wider tires....sometimes just a lighter foot. LoL

 

i never noticed clunking from my kazz 2way in my ae86 but i took about 2 hours or so breaking the thing in. never had people ask about the sound or ask what is up with my car..

 

how long have you had that car with the diff installed and how much did you drive it since you had it?

the clutches when new are put together need to break in, and the material are new/little smoother so its quiet. after a while, there is slack created and the material gets "grippy" with each other. break in period is to ensure all the clutches are broken in equally/evenly, and not lopsided to create the appropriate slack, again not one sided.
say if you drove from the shop after the install to your house, and there are 30 right turns and 4 left turns.. it wouldnt be even from the get go.
they make you break it in doing the exact same thing- figure 8, with torque removed/clutch in during the loop then gas on, then clutch-in, gas on the opposite way, repetitively.

the kaaz in the Ae86 takes a little longer before it starts to clunck and is a little less, my theory is because of the size, weight, toque distribution and the axle type. but it will eventually because thats how the clutch plates are made or designed to do.

other clutch type lsd work very similar, but they may have less clutch plates, hinge/release design may be alittle different, etc, so yes they do make less noise, or very little, or less harsh, or maybe more....
but the theory is the same.

if you can live with the cluncking and noise, get the clutch type. no matter how you look at it. the 1.5 is a little less harsh and more recommended for driving the car more frequently.

a torsen would be perfect for a daily and even a weekend warrior type deal.

if you are a little competitive, then get a 1.5 way, or for more harsher engagement a 2 way clutch type.

some additives may quiet it down temporarily, like ford friction modifiers.. but even so... it does what it is suppose to do, catch and release.

 

[QUOTE=5sp_jzz30;4251347]if you get the kaaz, tomei, or trd it doesnt matter. none of those require any modifications. take out the pumpkin, take out the diff. swap the ring gear over and reassemble. i dont know who told you that driveshaft modifications are needed but they are wrong.

it does take around 2.5-3.5 hours to do. it took me about 3.5 when i did it the first time around. taking out the diff is even easier of a job. that take under 30 mins.[/Q

any way we can maintain the original ratio if we swap ring gears from the open diff to the LSD diff?

 

yes ,u retain those..

u need to press out and in the bearings
