Unfortunately a direct swap is not going to be possible from one platform to another. Pic shows 4 out of the 5 AZ6 transmission output shafts (missing: IS200) used in the last 20-ish years. Note the difference between them, which also have an integrated 3rd and 4th gear. Some industrious individual may be able to work out how to make a Frankenmission out of these units, and if we have time to play around with it we'll do it since we have all of the parts on hand, but it may not be a priority.

We are still 2-3 months out on receipt of the prototype set from PPG, and once we get it we are going to try to break it. When we figure out what it can handle, and what final cost will be, we'll see if there's a big enough call for it to cross over to other platforms and work towards that if so.

Update

After a few months of street and track testing (by 949 Racing, Andrew Kidd and a few select street cars), we are now happy to announce final approval of our 3.33 final drives (Part No.: MF-TRS-02F33)!

these do NOT have the same fitment/quality issues as experienced with the previous batch of final drives. However, as this is a sample batch, quantities are very limited, so they will be offered on a first-come-first-served basis. Again, I am not a sponsor on this forum though, so please do not ask any sales-related questions.

there is one caveat though, and you need to be aware of this:

Noise - The oem final drive is virtually silent due to the angle of the gear teeth. With our final drive, the helix angle is not as great, therefore there will be a small amount of whine/noise. Note that this is whine/noise only, and NOT vibration. Unfortunately, it is hard for us to tell you exactly how much noise as:

1) Every car has a different setup/modifications that affect interior/exterior noise
2) Every driver has different driving preferences (e.g stereo, windows up/down etc etc)
3) Every driver has different noise sensitivity

What I can say is this:

Track Car - If your car is used mainly on the track, then this is a non-issue. Just enjoy the experience of the new gear ratio :)

Street Car - If you are already used to a noisy interior (be it stereo, exhaust etc), then this is a non-issue. If you are not, but you think you "may" be fine with a little whine/noise coming from the rear end, may I suggest riding shotgun in a Honda with a set of MFactory gears (be it a Civic with close ratio gears, or an S2000 with a final drive). This will give you the closest experience of the level of whine/noise and whether you find it acceptable or not. Again, every driver is different, so it's hard to answer the inevitable questions regarding this after I've posted this reply! haha

If you are wanting an oem-level of noise/comfort, then unfortunately, this modification is not for you. And if you are wondering why we do not just increase the helix angle to be like oem, the reason simply comes down to cost; the tooling cost alone would make this impossible.

If you have any questions, please don't hesitate to ask!

I would like a set

You have PM, order finger hovering

These are the same as the 3.30s listed at teammfactory.com? I hope so, I just clicked order

They are, yes

Would be cool to have someone do a side by side run on a street application of cabin noise. I understand the aforementioned points just seeing if anyone would be willing to do it. Very interested.

Nothing concrete at the moment

That ratio would pair well with a KMiata BMW 5 speed, fwiw.

Speaking as a former BMW nerd that came to the miata dark/gay side, the US spec E30 M3 with the OD gearbox (265) runs a 4.1 diff. The CR 265 with a 1:1 5th runs a 3.25. That gets you about 150mph but with a 205/65 15 tyre. The evo II has a 3.15. Redline 7200rpm.

my 323i had the 260 box and stock has a 3.46. Again, bigger tyres tham a miata. Redline 6500rpm

finally, one of those BMW gearbags would be a prime candidate for a samsonas gearset.

Samsonas Products

and they sound fucking great

and it looks liek VAC motorsports is a US distributor

Too many digits on the left of the decimal. And the gear boxes are plenty strong for a Miata already, just that a 1:1 5th gear made it difficult for many users to use factory diffs. These rear gearsets would maybe keep some people from swapping to getrag or Ford diffs for the taller ratios and higher top ends.

This is awesome news. Pair the 3.3 gears with our new Miata diff mount that deletes the PPF, and a cheapo bulletproof ZF 5-speed trans would play really well with a turbo BP setup. I love seeing new options come to the table for these old cars.

3.3 + 6 speed is essentially the same as a 5 speed with 4.10 gears 1-5

On a five speed I don't like it. 3.3 rear will make first gear very long. Actually every gear will be long. It will be like a normal five speed, only without first gear. And with a very long gear tacked on the end. Just dumb and inconvenient IMO.

On a six speed it's a no brainier. The shortness of the six speed gears and the long 3.3s cancel out and you basically end up with OEM five speed gearing, but with six speed strength and an extra gear for highway cruising.

I just put Xidas in the car so I need to get the wife a purse or something before I do this. But it's on the eventual to do list.

Gotta make room on my card for this guy again. The need is real.

Who do I contact with regarding to becoming a vendor?

I'm PM'd " Braineack ", but not sure if that was the correct contact or not?

In contact with my agent at IB to get my Vendor status sorted out :)

:likecat: that's good

Do you guys have the ppf delete on the website? Didn't see it yet.

Not on the site yet, but I can hear them being machined as I type this :) It will be available really soon.

Nice! Have you leaked pics or info anywhere yet?

Not yet. We are finalizing some aesthetics on one piece before doing so.

Contract submitted to IB, so our vendor status should be updated later today :)

Mods: Can this thread remain here/am I able to answer sales-related questions here, or should I create a new thread in the Classifieds section?

No problem at all, this thread will remain, carry on.

Thanks :)

I am so excited these are available. I can't order until 7/4. Have to clear some room on a card. Should I be worried about how many are available? And if can I get on a list.

Off the top of my head, there should be around 5 sets left on the shelf

MFMike < Auth.Vendor :D

It looks so much cooler in green too :likecat:

Mike,

Start a new thread on this mythical PPF delete

?

why would Mike start a thread for Kmiata?

I'll start one once the product is ready to go.

Because that way I can find a clue. I don't have one currently but it might come in handy later.

Hey buddy, I got my gearset today. The part number matches what was ordered, but the label says Fitment: Honda S2000 - Should I be concerned?

They share a ring and pinion. Same torsen as the msm

Hot damn, that's a relief. I was worried for a second there.

Just replied to your email. Yup, they're the same fitment

Ok. I do not want to risk missing one of these. Maybe I should get my brother to cover the order. Thanks

How would one get this to play nice with an NA speedo?

Use a VSS from an NB and a programmable speedo converter box.

--Ian

I've received a few PM's from people asking if we still have these available. As of this moment, we still have 2 sets left in stock

4.1 speedo sender and a scaled speedometer face from Revlimiter

If you run out of stock in the next week, how long until it will be available again? Waiting on a new 0% Apr card to arrive this week 😀

The current batch is a limited run, and we still have 2 sets left from over the past few weeks, so whether we make another batch or not will depend on the interest. If we do, it will probably be in pre-order format as I don't want to be sitting on 20+ sets of final drives and not knowing if/when they will sell.

One left.

Chrome kept kicking back security warnings, so I had to use Edge, but I think that was related more to PayPal than to your website.

The only SSL part of our website is when you go to PayPal, so yeah, something must be up with their certificate...

We are now completely out of the final drives. I want to thank everyone here for their support :)

Depending on interest, I "may" start a pre-order for a new batch, but not 100% confirmed yet, as we have other projects that I need to put up on this forum for you guys later this month (i.e our mid-range coilovers, our carbon propshafts etc)

Put a pre-order together before I buy a 3.63 R&P!

Official Pre-Order now posted up: https://www.miataturbo.net/group-buy...4/#post1499358

I linked the GB post to some friends, they are asking what conditions the test vehicles were in (power figures, testing time) if you have that information.

For this, you would need to check with Emilio/949 Racing as it was tested in their own car

MF 3.3 R&P Test Conditions
 

3.3 test conditions. I believe we are the only folks who have actually track tested this R&P. That it was on what is probably the fastest track Miata ever built should cover the "test conditions" validation.
400whp, sequential trans, Hoosier A7's, 1500lbs downforce, wheel to wheel racing.

MF 3.3 R&P is noisy. Noise = heat. Fine for track, too noisy for street if NVH matters to you. Don't ask me "how noisy?" R&P should not be audible. If I can hear it, it's too noisy.
Run a diff cooler if you plan to run this R&P at high power for sustained periods. Don't whine about blowing up your diff if you track over 350whp without a diff cooler. Also suggest dropping fluid after brief break in and 1-2 full heat cycles. Does not require special fluid, just whatever GL5 equivalent you choose for the diff.

We paid for ours and are not a dealer.

Thanks for clarifying, I expected as much myself but they asked me to check.

Small correction: Not really. There's more noise because of the way the gears are cut, it's not going to add heat though.

But as you stated, if you're seeing high heat in the diff, you should be running a cooler either way.

Would these gears benefit from micropolishing? I have a shop that can do it, but is it worth the extra few benjamins

Was surprised to o have received my gear set today! Was expecting them to show up in a few weeks at best! Sending them out for micropolishing and assembly. Will update in a few weeks
