Quaife lsd differential

[Dsm559]

Worth it or not?

 

[iceguru1114]

Front, center, rear, all of the above?

I dont know what you mean by front center rear or all of the above. I have a gst so want to know opinions.

 

[zedicus]

you do not have any car info filled in. he might have thought you had a GSX. a GSX would have 3 locations where a LSD could be used, front, center, rear. a GST would only have 1 location where a LSD could be used.

i am also looking into an LSD, my GST is at 16lbs boost and there is simply no traction after spool. i have tried a few sets of tires, i have urethane motor mounts, i am replacing most of the suspension soon, (new parts stacked in garage) but i still think i may be looking toward a LSD as my boost goal is about 20lbs.

Lsd should improve traction quite a bit. Though wavetrac might be a better option, and kaaz plated diff might be better for roadracing. Just my .02 from what i've read.

Op: Perhaps you could share why you are inquiring about an LSD. What is the main usage of the car?
On the Quaife: Is it worth it?
That depends on what you want out of the car.

• For 1/4 mile and drag racing? No
• To have another sticker on my car? No
• For quicker corner entry/exit? Yes!

If you would like more about the technical differences about the different LSD choices for the fwd DSM, look no further:

The Quaife install was my first experience opening up the trans on my first DSM. The install was surpringly simple. The Quaife does not fully lock initially in a straight line. I did still notice some torque steer, but much less than with the OE open diff. The small amount of torque steer was more than acceptable as the biggest benefit of the Quaife is that cornering was supurbly enhanced. This was by far the best performance modification that was made to the car.

If I remember correctly, Quaife does not make an LSD for the GSX rear. Only front and center, I remember looking for one and ended of getting a KAAZ.

@ 2gmitsueclipse - Why no good for 1/4 mile? Mine improved my traction by double on my GST.http://www.dsmtuners.com/members/2gmitsueclipse.53674/

I was referring only to the "worth" of the Quaife specifically. I am not saying that it is no good in a straight line, but there are better options for straight line performance from an LSD. The Kaaz LSD would be a better choice in this case because it locks from transmitted torque. The Quaife locks from the difference in torque transmitted to each axle.

I can attest to that. The KAAZ locks solid! I was on the highway about 100 miles from home and hit a pothole in the road. All of a sudden I heard a clunk and I had to keep the steering wheel partly to the left to stay centered. Turns out the the rear passenger side trailing arm snapped. Because the KAAZ was locked so solid, I was able to drive the car all the way home. If it had not locked, the wheel would have just moved forward and rubbed the wheel well.

I love mine. Made the car so much more fun through/out of corners. It helps in a straight line too. Still not a ton of traction in first gear though. Made a huge difference 2nd and higher though.

^^Correct. I think 2gmitsueclipse gave a pretty good response and posted the appropriate link. No need for me to add anything.

I have tried kazz, quaife, and factory torsen that comes in some JDM cars. they all perform quite similar. they all make a huge difference in driving through a corner under power. thats when you will notice night and day difference. straight line traction is only marginally improved under certain conditions. my track time did not improve in my 89 mirage turbo. it still spun bad with LSD on board. sticky tires are far more important for straight line accel in FWD car. drag radials made a huge difference where the lsd made hardly any. I hated the kazz diff. made axle noises that sounded like the cv shafts needed to be replaced. and adding lsd additive to oil made the smooth shifting trans not so smooth. it has adverse effects on syncros.

obx makes cheap lsd for 2g cars. you may consider that one for a lower power application.

There was no factory Torsen..?
Unless you're talking about the Evo 4-9, then yeah.

Of note, my 2008 Civic Si with factory Torsen has a good feel to it, it helps in winter.

 

[zedicus]

the OBX product is similar to quaife in how it works. it NEEDS the belleville washers verified if not just replaced before using the OBX LSD. there are some other mods that can be done to it also. but for a cheap LSD (in the limited space ive seen them used) they are not bad. all the china-bay turbo civics out here seem to use the OBX (most have not even verified the belleville washers are facing the correct way) and i have not seen any of them explode. though i have seen civics shrapnelled on the side of the road for other reasons.

 

[94awdcoupe]

there is a factory torsen. I have purchased four over the years off ebay from sellers in japan. I believe they came in the cyborg hot hatches with the 1.6 mivec. good deal as well. paid around 250 shipped for first two. now they go for around 400 if you can find one. most are small axle, but one came in fwd 2g style. and they look the same from outside. I installed that one in a 99gst with some fancy spacers. the blue car in my sig is currently using one. the summit project has one on standby as well. I can take pics of that one if you want to see it.

 

[Canadian_CD9A]

Ah, the F5M42 diff. I didn't know it fit since most manufacturers' CJ4A/CK4A Mirage LSDs don't interchange with a Evo/DSM W5M33.

The Ralliart diff is of course an exception, it was originally intended for the Mirage but fit the Evo (might have been for convenience).

Good to know!

 

[94awdcoupe]

that info passed around is wrong the cj4a diff is the one that fits fwd and awd

last on I got off ebay
JDM MITSUBISHI MIRAGE HELICAL LSD 4G92 MIVEC MIRAGE ASTI CYBORG CJ4A TECHNICA

 

[Canadian_CD9A]

Kaaz, for example, lists DBM2010 for CA4A, CB4A and CD9A/CE9A Evo, but DBM2050 for CJ4A/CK4A
Cusco lists LSD134x for CA4A, CB4A, CC4A, CD9A/CE9A, but LSD146x for CJ4A/CK4A.

Some interchange, some don't. A quick check on the internets shows that indeed the F5M42 (CJ4A/CK4A) helical LSD fits W5M33 (CD9A/CE9A/DSM) transmissions.

Yeah mybad on that one about not being specific enough.

Thanks for your help. My reason for this inquiry is my goal to hit 10's.

I would love to run drag radials but its gonna be my daily.

If you have a GST, these seem to be conflicting goals. That load transfer to the rears is gonna make the launches required for those sorts of times a little difficult for a FWD car without drag tires. On the plus side, you can easily swap out to some drag tires at the track.

I'm gonna soap box a little here because I used to have a crappy VW Jetta and lofty goals (didn't work out so well), so I can speak from experience here. With a goal like that, make sure you have the closest thing to the right tool for the job right out of the box.

That being said, it's your car, it's your project, do whatever blows your hair back, sir.

Impressive!! most impressive

Hands down need some qtp's at the least for that goal. Check out richard33's car. I personally love my Quaife LSD in my gst. For corners and striaghts. So much easier to burnout and launch. I was launching at 5250rpm and with 10psi boost and cutting low 1.7 60'. No way your doing that on drag radials and open diff. My gst will be back at it once my hands heal from my surgery. I have everything I need to hit 10's
