I tried installing a b16a quaife LSD in my (thought to be) JDM b16a hydro tranny. The ring gear of my (thought to be) JDM B16a tranny was oversized for the b16a Quaife differential. From what i'm thinking, i probably have a gsr diff, and so i am getting a gsr quaife instead.
can someone verify what i have/don't have, what i need/don't need?

this pic shows how the stock (thought to be) b16a ring gear doesn't match up with the quaife b16a's diff holes.



here is a pic of the stock (thought to be) b16a differential. check out the markings, can you identify it?


i appoligize for the size of the pics, i'm not on my comp and didn't know how to shrink them.

My second question is in regard to the differential side bearings. Unaware of a difference, I orinigally ordered ones for a b16a tranny, which from my understanding are NOT tapered. I'll see if they're tapered or not tomorrow.

 

yeah you have the gsr/type r bearings on you stock diff. So i would assume that its not a b16 diff. And a b16 ring gear has a smaller center bore. YOu could just get a b16 ring gear

 

Just out of curiousity, whats this got to do with forced induction?

it has nothing, but i expected someone here to know b/c its a readily used lsd & upgrade with forced induction. it only took a few minutes to get a response here, when i posted it hours ago in the tech forum.

i know a ring gear would solve the problem, but i'm just sending the quaife back for the gsr one.

does that mean to replace the diff bearings shown (tapered ones), I would just go to Acura & get them for a GSR?

thanks guys.

up one last time for the night...

 

91005-P80-E31 Differential ball bearings (x2)

That's the part number for the enclosed ball bearings. It'll make it much easier to shim the differential for little to no clearance in the casing.

They're for the B18B tranny.

a new ring gear alone will not solve the problem
if he changes the ring gear and not the countershaft, isnt going to work
he needs to change the (final drive) wich is the lower gear on the countershaft itself that runs agains the actual diff ring gear
if one of them is changed they cant work,... they go togheter as a pair....

Exactly correct.

nice correction guys, if its true. b/c several others said i could get the ring gear to fix the problem, which i didn't want to do anyways.

 

If it's the same final drive then you can just change the ring gear. The gsr and b16 both have a 4.40 final drive, so you CAN use a gsr ring gear with a b16 pinion gear...

Correct Tony, only if you have the same FD.

 

you can also use the 1999 si bearings. They are the same. (I don't have a hookup at acura but do at honda.)
