yeah i did not see that but when hes talking about transactions in dollars and that the OS giken being twice as expensive as the KAAZ (a $700-$800 cost new according to him, as opposed to the 900$ you can get the OS giken in japan ) it is safe to assume that the location is possibly USA. my bad i suppose

Anyway, best of luck with your search

I was converting it to dollars for your benefit, but I wasn't using accurate rates....
Actually, it seems like the Kaaz market prices have gone up significantly. If you go by MSRP, the Giken isn't that much more.

It used to be about 80,000 yen vs 130,000 yen or so. Now it's more like 100,000 vs 140,000. So 1.4 times as much.

The used unit I found also comes with a ring gear. I'm eventually going to go count the teeth to see if it's a 4.3, and snag it if it is.

Hmmm? 1.5 https://page.auctions.yahoo.co.jp/jp...on/o1066495629. This mob always seem to charge a bit of a premium, but half price I guess.

Ring without the pinion in that other one, if that's the intention, is a bit iffy. I have heard of non matching pairs being used on a weekend as a desperate fix though.

I think it came with a pinion, too.

Mods,

daniolmu is a spam account. The posts are just copy/paste from earlier replies from the same thread. The dude is probably making an account to scam people

I've looked though his post history it's all the same thing

yes, for good reasons.

I always recommend the OSG, it costs but it has a completely different locking design that is great on corner exit. It’s hard to explain, but the torque lockup feature works the opposite of the usual clutch pack LSDs. And it’s quiet; no popping or clanky metallic sounds.

and please, please, please; use their special oil regardless of the cost. It’s not like you’re going to be changing it that often and it does matter.

some of the hardcore RX8 autocrossers claim a 1:1 setup resulted in being faster and more consistent than 1.5:1. It may be due to how the ABS/EBD interacts with it when breaking hard/late into turns. Which is pretty similar to a Torsen as well.

The track people seem ok with 1.5:1, but their transient dynamic is less intense.

If you order one you can request to have it tuned specifically for your whp/use intentions prior to it shipping. Which will be done at the USA location in Kalifornicationstan. They used to sell a kit for tuning it yourself, but they ended that a long time ago.

The OSG is the same Salisbury (clutch-type) "locking design" as the KAAZ, CUSCO, etc... It has 4 drive pins that ride up on 'ramps' that squeeze clutch discs to reduce the slipping between the right and left tires (lock). The main difference in OSG is the use of coil springs to resist the clutches from locking, which smoothens out the rate of it locking.

Do you have an OSG on an RX8? I haven't driven an OSG RX8 in years, but my NSX and many S2000s pop/chatter a lot more than i'd like; but they are significantly better than KAAZ/Cusco in this regard.

Autocross is extremely low speed and you don't want much differential lockup on deceleration, which is why 1-way LSDs that do not lock up on decel are probably more successful; making the car more nimble and able to rotate and turn. But at higher speeds, a lack of deceleration lockup can cause the car to rotate and be less stable, requiring suspension setup changes to stabilize the car.

I've been running a carbonetics 1.5 for years. It has always been quite noisy. The Garage K-something 4.77 gears probably contribute to that noise
