I would say thats a 1.6 just like everyone else is saying. I had my 1.6 diff open and it looks exactly like that. I dont really understand why you are so eager to disagree with everyone and Im a bit surprised you haven been beaten with the ban stick yet.

Either way, toss it and get a 1.8 diff.

Everyone saying this is a 1.6 diff is WRONG. The miata expert himself seems to be confused. Here:

''My computer says your pictures are virus infected, so I have to be satisfied with looking at the thumbnails. I assume the stub shaft splined ends are identical? That and the small round hole say Torsen 2. Therefore the differential is not a 1.6 liter of any kind. New theory for the square stub shaft flanges is then that they are RX7 parts.''

If you're still hung up over whether this is a 1.6 or 1.8 style unit, just measure the diameter of the ring gear.

And count the number of teeth on the ring gear, and the number of teeth on the pinion gear.

Do what Joe says.

keep on failing man we only try to be constructive for so long.

Dude, with the magical diff out - turn the Drive shaft input by hand and please tell us which way the halfshaft flanges turn? Do they turn in opposite directions or the same? This will tell you whether it's open or not. As wether it's a 1.6 or 1.8 diff - do as Joe says, measure the ring gear.

And on the concept of LSD oversteer vs. understeer... try driving a car with a welded/locked diff out of a corner. Both rear wheels having the same power to the pavement will tend to push you in a straight line (your understeer) vs. breaking loose - unless you have mad power (like me - sort of). I've got an OS Giken in mine and the corners are so much faster now, esp the tight ones, with less oversteer than when I had the open 1.6 in (at the same speeds). Crazy faster. But I still get oversteer as I'm going that much faster now, and the 225hp is enough to kick out the rear coming out of the tight corners.

Really??? Mine too!! OMG!

Someone stopped bumping their thread 3 times a day. Im going to assume that he found out that it was an opened differential and was embarrassed for acting like a douche, so now he has left the forum in shame, hopefully never to return.

So long noble drifter, May the zip-ties be with you, always and forever.

hey douchefag, found out my lsd is mazdaspeed clutch type lsd 2way. You were kinda way outta line with you open diff and your douchetastic attitude. F you very much. Late

You Fail.

The flanges on the stub shafts don’t look like any 1.6l diff I have seen and I have looked at a multitude of them including GTX diffs, Viscous diffs, and Mazda comp 1.6 clutch units. I am pretty sure that is not a standard 1.6l diff.

I actually think it might be an RX7 clutch type about 85 or 86 I think. I had one of those but I sold it some time ago but I sold it and I can’t remember exactly what it looked like. pretty sure it looked sort of like an Open diff but not quite there were some clutch packs nestled in what sort of looked like an open diff.

Interesting how much Fail there is in this thread and pretty much no Fail from the Noob with only 30 posts.

Like I said I think it is an RX7 clutch type. 1.8l size ring and pinion probably a 3.909, same gears Im running in my car but I sapped them on a torsen.

Kei, Did You count the teeth yet

Bob

Edit, I looked closer at the shape of the shft and splines on the stub shaft. they look 1.6l. This unit is different than anything I have seen before.

Hey douchebag, how about you suck my dick.
You are so lucky that anybody put up with youre fucking attitude at all.

Yah, because opens diffs dont allow you to oversteer at all right?

Even if it does have an LSD, which he still could be full of shit about, his logic behind assuming that it did is totally flawed, and his little ricer drift video makes it even worse.

lulz.

How about a big nice cup of shut the fuck up.

je ne comprende pas francais.
