I just got my Cusco RS LSD in today, and just thought of sharing some pics with you. I got it from Z1 Auto. Adam, thank you for a great service and help

Also could someone look at this file (click right mouse button and “Save as” scanned documents) it includes some documents I got with the LSD and its all in Japanese. So if there is anybody out there who knows Japanese if you could please give me an idea on what it means and if there is anything that I should give special attention to. There is one page that has 60, 80 and 100 what does that mean.

Thanks,

Az

I don't read Japanese, but I would venture to guess that 60 80 100 refer to the % lockup.
Don't forget to give a review when you get it installed. My nismo lsd is simply awesome.

 

You're right the numbers do refer to the % lock up. Most people keep it at 60% for street use.

But that looks really nice man let us know how it goes.

 

Yah I think you guys are right, but how would I know which setting I have??!!

Thanks,
Az

 

It ships at 60%

I'll get you a translated copy via email this week..just need to sit down with a pot of coffee to do it

 

is it a 2 way or 1.5 way?

 

Thanks Adam

Moroccan Mole, Its 1.5 way and can be set to 2 way

 

What is the difference between 1.5 way and 2 way?

 

oooh, that's nice...

how difficult is it to change it to a 2 way and back?

 

Hi there i'm new to the tuning car stuff ..
so .. can anyone tell me what does LSD do?? ^^||

thanx

 

phile,
A 2 way (the way I understand it) is that it works on acceleration and deceleration, however, the 1.5 works full on acceleration and 50% on deceleration.

Moroccan_Mole,
I have no idea how to change it, I guess the best person to answer that would be Adam.

Tien,
An LSD is a Limited Slip Differential. to best understand it go to this site How Differentials Work

i read that article, and kinda get an idea what is lsd; so what's the difference between the stock one and the aftermarket one?

correct me if i'm wrong, LSD only comes in play when u'r making a turn rite? what kinda improvment do u get? something like your tire won't slip and u get more grip? am i right? is there anything else?

also i check Z1 auto site, cusco has 2 diff lsd, type MZ and type RS, which one u got? and what's the diff between the 2? it says MZ comes on strong and the RS comes on more gentle what is that supposed to mean? can someone explain it to me?

many thank to you guys answering my Qs, and correct me anytime if anything i said above is not right.

thanx ^^

 

the stock one is a viscous type LSD and the one I got is a clutch type LSD.

It will work when ever you have a wheel spining faster than the other wheel.

The main thing for making the change for me was the response time. On the stock one the response of the viscous is slow in comparison to the clutch type, due to the fact that the viscous needs to heat up first to look. Other than that, this clutch type LSD can handle more horsepower than the stock one.

On slip, the LSD will not help directly in reducing the slip, but will help indirectly by distributing the power to both wheels equally thus theoretically you should have more grip.

Overall, the LSD will help you going in and out of a turn and also will help you in a straight line should one wheel loss traction and spin faster than the other wheel. This what I know I'm sure others have more info on LSDs and could explain it better

The one I got is the RS type

They are referring to look-up. And that is precisely the difference between both, is when the LSD kicks in, the MZ type looks up harsh (Snap!!) but the RS type looks up smooth

You are very much welcome And please correct me if I'm wrong.

"The main thing for making the change for me was the response time" <--- do you mean throatle response?

thank you so much w/ all the info ^^

 

Viscous works by fluid in the diff heating up causing the diff to engage...the clutch types literally use clutches.

Viscous works fine for a stock car but gets taxed easily on track days, especially on tighter tracks. Clutch types don't have this issue, plus they are adjustable for lockup %,. The Cusco is also adjustable from 1.5 way to 2 way by repositioning the cam inside the diff...its not a hard job to do at all and I'll outline it in the translation I send you

 

what is the Nismo diff, clutch right?

 

The nismo diff is also a clutch type .
However; what makes the Cusco RS different is it uses "coil springs" to tension the clutch pack which are suppose to deliver a smoother engagement. The RS should also remain more consitent as it wears over time.
