My tranny just took a crap and i got a m2f4, i know it doesnt have lsd and i read somewhere that the jdm lsd doesnt work in the usdm trannys. So will a kaaz or quaife lsd work in the M2F4 or cant you put lsd in the M2F4?

 

 

ok thanks, i heard the m2b4 lsd wouldnt fit and was worried that the aftermarket ones wouldnt fit either.

 

Nah... The M2B4 is the oddball tranny. Its the red headed step child of H transmissions. Youre good.

 

you can use the M2B4 part of the transmission housing that holds the differential and cut the webbing from the other side of the housing so your JDM LSD will fit.

 

Ive read the M2B4 diffs are weak. Any input?

 

quaife

 

mfactory in mine,

 

I have one in mine and I have had no problems with it. It is actually easier to break a Quaife than one of these. The JDM LSD do not use gears or clutches, so no gears to break and no clutch packs to wear out. It is called an uncontained viscous diffferential. Read up on it.

 

where are ppl ordering their quaife lsd's for 800 bucks? every i looked they're all 900-1000

 

This store through google shopping has it for less than 750 shipped. It's the lowest price I've ever seen.

Viscous lsd's are next to useless compared to helical and clutch-type.

 

please explain. i had one from a JDM tranny installed and it is alot better than the open diff that I used to have. I mean would Honda put a useless LSD in one of their cars,really. All I know is i can roast both tires really good at the track where before it was all one tire on fire.

 

Viscous is def better than an open-diff, but it's severely lacking compared to the other two. Viscous usually has much lower bias, and it's not very responsive at all. There's a reason ITR, Euro R, S2k's etc got torsen diff's. It's also no coincidence that a lot of Z (and other models that came with viscous stock) owners swap out the stock viscous diff.

It's always better to get a non-M2B4 trans and add an aftermarket diff.

 

right. I just had some spare stuff laying around and had a very low mile M2S4 tranny and wanted to try it out. Would a diff like this benefit from a additive such as this?

currently using Penzoil synchromesh and I am happy with it.
