OEM K Series LSD VS MFactory / Quaife LSD

Functional difference between an OEM Civic Si L-S-D vs an Aftermarket L-S-D such as Mfactory/Quaife Helical Limited Slip Differential.

[@Alex12925]

I love learning the little things

[@EJ2BSeries]

What is better mfactorY or quife for high 600-800HP on streets. For the best traction on both wheels. Thanks

[@1320whtrex]

Neither will be "better" per sé. They both will get the job done and have about the same longevity for that hp range. You can't go wrong with either decision you make.

[@kommentelek.]

Hi, are you talking about the helical/torsen type Mfactory LSD or the Clutch /plate type (1.0,1.5,2.0) Mfactory LSD?

[@thenameforcorey2261]

I'm not outta the water yet tho. So it looks like some trash went through this diff and kinda roughed up the outside edge of the worm gears ,not the actual face of the gear teeth that mesh together with other gears tho ,the face of the gear teeth look nice a s smooth. It also roughed up the outside of the case alittle. Do u think I could polish that roughness out and get away with it since the actual face of the gear teeth are all in good shape or should I just say f it and get a new one . Srry for being so long winded

[@leonardovelasquez2801]

Is a oem lsd or the m factory lsd better? Or do they perform the same? Thanks!!

[@Loyal_Honda_Fan]

The stock K series diferentials are not good at all unfortunately, the aftermarket ones are redesigned and perform lots better, even the one named somehow like black(something) costs arround like 600 euros and perform waaaay better than stock

[@sheheensumad]

Awesome video! What would you prefer Wavetrac or Quaife? Which brand is superior when it comes to overall use. Thanks

[@Ocurrey1320]

I’ve used both, seen them both being assembled and they are almost identical. You honestly can’t go wrong with either brand. Neither is “superior” to be honest. Equally excellent products

[@sheheensumad]

@@Ocurrey1320 thank you for your response. I really appreciate it.

[@lorenzogrant6097]

I have a b18b trans that will go into first gear without grinding unless the car is at a complete stop and the clutch pedal all theway down but all other gears are fine. What can cause this?

[@kibawhitefang7176]

I’m very sure your first gear is worn out, usually common with the first gear and most probably is a sign that the car has been beaten hard on that gear. I believe you can get a new one.

[@kibawhitefang7176]

I also recommend to first do a transmission oil change first, and see if that helps to clear off the problem. I would also check the clutch.

[@rj6198]

while diff/trans is installed in my car b series M factory diff .I will be lifting the car with wheels on will i perform this test in 1st gear or in neutral?

[@Ocurrey1320]

Put it in 1st gear and attempt

Would this be good on a all motor 04 tsx trying to push around 280-300

[@Ocurrey1320]

Yes it would

@@Ocurrey1320 which diff should i get ? Wavetrac, quaife, mfactory? It’s for a k24a2. Also, I will be ordering a full rebuild kit at the same time as well, which one should i get, Synchrotech or Mfactory or another brand? And material, Brass or carbon?

[@1320whtrex]

@@user-hh4hc2lt6e Wavetrac. Mfactory & Quaife are the pretty much the same. And carbon will always be better than brass.

[@Alexlachica37]

If it’s in the transmission would I be able to turn it by hand? I just installed my new mfactory lsd I put my half shaft in to see it turns by hand gear are in neutral, and it’s spinning. Is it possible that I’m able to spin it and even on All thru gear? Or do I have a bad lsd?

[@Ocurrey1320]

You shouldn’t even be able to turn it by hand. When I say turn I mean one side independently from another. With a new diff, the shims/springs should be set so tight that it only spins/operates properly on the ground when in motion. Traditional human strength shouldn’t be able to turn it in the air

[@Alexlachica37]

@@Ocurrey1320 thank you very much! And thank for replying to asap. Im going to contact the seller to see if they can have my new lsd check out. It’s unfortunate that I might have got a bad lsd, I mean I just got it last week and this video was very helpful!🙏

[@eas900s]

I just had a mfactory delivered and held in my hand shook it and tipped back and fourth and I hear a rattle noise inside is that normal

[@Ocurrey1320]

Yes that is perfectly normal. The swivel gears and plates that are inside there are not extremely tight so there will be some plate to allow the swivel gears to rotate.

[@headported]

Do you use red or blue loctite or non on the final drive bolts?

[@Ocurrey1320]

I’ve done blue and I’ve done it without. Don’t really see the need for red. If you’re going by OEM spec according to the manual, it makes no mention of a form of loctite being used. The bolts should be tightened to 83ft lbs of torque. You shouldn’t have an issue either way if done properly.

[@headported]

Do you know the torque specs for the countershaft hex bolt? Is it 89lb/ft?

[@Ocurrey1320]

@@headported 87ft lbs

[@headported]

thanks

[@headported]

[@cheese7837]

is quaife lsd any good from your experience? was thinking of buying one for dsm fwd .

[@Ocurrey1320]

The Quaife LSD is a great great product.

[@mnrracing1949]

is this clutch type or helical ?

[@Ocurrey1320]

Helical

[@fabiodimonte6096]

I had to remove it from my car because it made so much noise when turning

[@enriquegonzalez7059]

Why is it called a lsd ?

[@averyalexander2303]

LSD = limited slip differential

[@lexzenis2544]

Or if you're a stoner: LSD = Lysergic Acid Diethylamide

[@teddy_awdB19]

Good info
