My $130 R-160 LSD

[VintageRice]

I posted this in my old thread but didn't think it would get much views cause its a 4 yar old thread.......

 

 

Anyway yes, I put a viscous LSD from a 2002 Outback into my 510 for $130.  And it works. Here's the details.

 

 

First I read a post by "domn8tr" posted in the "subi R160 LSD link"  sticky thread.

 

It reads:

 

I noticed this info is about 10 years old now, and doesnt cover the Subaru R160 VLSDs that came in WRX and Outbacks and others from '99 and up.

 

Any subaru legacy outback with cold weather package from 99 to 03 will have VLSD R160, and any Outback from 01-03 will have the VLSD as STANDARD equipment. Look for the heated windshield wipers and heated seats to know if the car has cold weather package. These cars are now over 10 years old and very easy to find. I found three R160 VLSD equipped outbacks in the Ecology just this weekend.

 

They are available in 4.11 for the manual transmission outbacks and a nice zippy 4.44 in the automatics.

 

In '99 Subaru changed their VLSD design to no longer require the longer extra set of splines on one axle to engage it.

This means all you have to do is have some c-clip gooves machined into the end of your factory Datsun axle stubs and they will clip right into any '99 and up Subaru R160 VLSD and will engage the VLSD and work just fine! The machining cost only 60-100$

This makes the total cost for a 4.11 VLSD under 200$!!

Thats a real ratsun price for an LSD!

This almost sounded too good to be true!  but.....

 

So I did a Inventory search and found a fresh 2002 Outback at Pick n Pull. In neutral, wheels spun the same way.  Check.      Picked it, Pulled it. Paid for it.  $99.

 

 

 

The 02 Diff

 

 

C-clips  

 

 

 

 

 

Put my 510 stubs into it. Did some measuring. Figured out that the c-clip notch needed to be about 5mm in from the end of the stub. I did this by measuring the distance that the sub moved from sitting against the clip, to fully seated.

 

 

Got the stubs machined. $30

 

 

 

Stock 510 axel dust caps fit.

 

Have to swap the 510 drive shaft flange onto the subie diff. But you need the subie dust cap.  The subie dust cap is crimped on, the 510 is tack welded. Cut/pry them off, put hte subie dust cap on the 510 flange, tack weld it on, and bolt it back to the subie diff. 

 

 

 

 

Snap your newly machined stubs into the diff. Now its time to re-install in your 510.

 

 

 

Complete swap by filling with your favorite 80w-90w gear oil and do two wheeled burnout to confirm. :)

 

 

 

DIsclaimer  This is just what I did, you don't have to. If you do, and screw it up, not my fault.

 

Only one test drive so far and if you want a full locker this doesn't seem to be it. if I had to rate it on a scale from "welded diff"--- to ---"open" it would be a 5  right in the middle.  I'm no Diff expert but in gravel and my shop there's two tires spinning. On open pavement and clutch dump, i get the rear end to break loose for a second and then one tire bites more that the other. It grips really well, and should be perfect for my tame street car. 

 

Just thought there should be a good DIY thread on this LSD that only cost me $130.

Ah......

That isn't a vicious LSD......

 

Correction: That isn't much of an LSD, as they had a tiny vicious coupling under the ring gear.

Hope you don't have plans for any serious power.

[VintageRice]

Nope. Mostly stock R1 carb' single cam KA.

[G-Duax]

You are probably going to over power that thing in a corner.

My 620, with an open diff would leave 2 black tracks if I launched on a flat surface.

I overpower my vlsd with my r1 Kade. So it doesn't take much

This is a cool mod for a moderate power car. Open diffs are a tease just when you get going.......ziziziziz, no forward bite. Welded diffs suck (sorry kids) and are an abomination. Lots of people run them but they do the handling no good at all, they kill the turn in and mid corner speed. Of course if you're racing against me I'll happily tell you a welded diff is just fine. F1 cars have fancy diffs for a reason. For $100-200 it's worth doing the VSLD. Given the price of installing big horsepower in a car, a proper LSD is not a lot of money but agin for a moderate powered car well worth it.
