Mfactory R200 LSD

Recommended Posts

Found a socket that fit in the two washers very close and got them lined up to each other and the axle bore. Got the runnout and backlash down to .001" variance. Ended up with the same shims as the old carrier. 2.30 driver, 2.15 pass. and the tooth contact is good. So back together and back in the car, should be on track in another month. So all's well that ends well.

One question, the TeamM Factory box the carrier came in says "designed and engineered in the USA". But it doesn't say where it's made?

 

Found the answer in TeamM Factory FAQ. Taiwan is pretty good, and still better than China.

Looks great!

Here is a FAQ on mfactory site about diff fluid.

http://support.teammfactory.com/support/solutions/articles/8000007998-do-your-limited-slip-differentials-require-any-special-fluids-or-additives-

We used amsoil severe gear 75-90 in our diff and rb25 tranny.

 

 

From MFactory  FAQ's

 

Maintenance:

 

Oil: Regular 75w90 Synthetic Oil for Street/Spirited use. Heavier 75w140 for Race Applications. Recommended brands include Torco SGO and Redline NS. Limited-slip Friction Modifier must NOT be used, as Torsen (helical) style LSD's rely on friction in order to function.

Did a track day at the Ridge Motorsport Park with this diff installed. No more one tire spinning. Consistently faster coming out of the slow tight corners, especially the hairpin. No noise from this thing, didn't even know it was there aside from the lack of any wheel spin.

 

Ran the Redline 75-W-140-NS

Apologies if this has already been asked, does this work with both short and long nose R200's? I know you said earlier that it worked with 29 spline. Apologies again, I have entered untouched ground with my Datsun build and differential/rear end work is surely one of those areas that I am weak on. I currently don't have any clue what type of direction I am going, but R200 is looking like its going to be the easiest solution for my build.

 

Thanks in advance.

The next batch is ready to ship, I messaged everyone back that was interested in buying one. If anyone else is interested please reply here or send me a message.

Gaiden_08 I'm almost positive it will fit in a short nose R200, but i am curious as to why you want to use a short nose over a long nose? The conversion from a long nose r180 to a r200 long nose are pretty easily obtainable.

I have given the S13/14 subframe some thought which is why I was thinking about a short nose. Also, it is very hit and miss over here on the east coast for parts at times (my experience at least). So finding the right parts is part of the thought process as well.

Just got my LSD from exlifesaver. Chip was great to work with and answered all of my questions. I had the LSD just a couple of days after ordering. The process was super smooth and pain free. The LSD looks to be very high quality. It should be in and running within a couple of weeks and I'll report back how it works.

So the LSD went in really easy! I should have taken a picture to show the high quality machining and the mean look of the helical gears.One thing different, and maybe because I am new to LSD's, is that it would turn both sides in opposite directions but was very resistant when turning by hand.

 

So this thing works really well! There is no binding or odd handling when driving around in parking lots. It locks with no notice of anything but the rear end drifting a bit because both tires are spinning. Very smooth in my 75 behind a LS6 pushing 420 on the dyno, 349 to the rear wheels.

 

Thanks Exlifesaver! This is a great deal for a very high quality LSD.
