Subaru R-160 CLSD 3.70 from '87 RX AWD Turbo.

 

Question:

How many pinion gears this LSD diff. have?

How much horse power safely can it handle?

Is it worth swapping my open r200 3.54 to R-160 CLSD 3.70? Currently, I have stock L28et with 82' zx tranny.

 

Thanks in advance!

I ran one of those diffs in my 510 with a VG30 turbo for many years with daily driving, autocross and hillclimbs without an issue. Torque is what kills them and I was putting out roughly 400 ft lbs of it. You will be fine. A friend of mine ran one for years with a VG30DETT and no problems. Definitely worth it over an open diff!! Just my 2 cents.

Hello from Norway,  cheap and simple R160 VLSD installation in 240Z, I hope it is ok to post this here?

 

Some years ago I bought  a Subaru R160 VLSD , cost me 150 usd at Ebay but with shipping to Norway I think it was around 300 usd total,.

Then I had to buy some VLSD axle shafts to modify. Around 150 usd total with shipping.

I used a 240Z old R180 as donor for the axle shaft connection plates to the Subaru diff. splines

  1. We first measured the distance between the axle shaft  installation plates on the R180 donor.
  2. The r180 spline axle was removed and the plates cut off.
  3.  The Subaru  r160 axle shafts was temporary installed in the r160 , we measured where to cut to get exact the same distance between the axle shaft  installation plates as on the r180
  4. The r160 axle shafts were cut off and the splines ,one long and one short was then adapted to the r180 shaft  installation plates.  A friend did that at his little machine shop.
  5. Then I just installed some new axle oil seals ,don’t remember the price but very cheap.
  6. Installed the new splines,  filled the diff with oil.
  7. Removed my old r180 and installed the r160, I think I used 3-4 hours to finish this installation.
  8. Test driving and it worked  well , total cost around 500 usd in Norway,  200-250 usd was just shipping costs. But for me that is a great price and also fun to have done.

Take a look at the pictures also, I am happy if it can help some of you.

Regards

Olav
