BRZ/FRS AZ6 Manual Trans Upgraded Gearset
 

UPDATE: Jack's Transmissions, the shop we worked with to literally get this gearset up and running is now the official US supplier of this gearset. It was a serious process to get everything up and running with PAR, but now they're ready to rock. Shoot me a PM for Jack's contact info, they'll get you taken care of. If you know anything about them, they stand behind everything they do, can't recommend them enough.

Hey guys,

Wanted to get the community in on something we're working with.

Some of you know about the #RevvProjectBRZ which made 630rwhp (more to go), and naturally with that type of power we were just munching through stock transmissions.

In our efforts to find alternative solutions (V160, R154, TKO, T56 etc), we kept coming back to available upgrades for the AZ6 (or lack thereof).

Finally one of our partners that our trans shop regularly works with just came out with a 1st-6th straight cut syncro set, full gearset for our platform. These guys have a ton of experience in the other-platform (Miata, S2000 etc) AZ6 and are stating that the set will be able to hold more than 700 ft-lbs.

I've been able to talk them into a small group buy, 5 total sets.

If you're making more than 500whp, you have to ask yourself: how many transmissions will you be going through until it's time to upgrade?

Set includes:
Input shaft
Output shaft
Layshaft
1st gear
2nd gear
3rd gear
4th gear
6th driving gear
6th driven gear
Intermediate gear

-1st - 6th Straight Cut Synchromesh Gearset
-Shift and drive like standard with a mild whine. “Due to the way that we manufacture the outbreaks they’re not terribly noisy due to the accuracy”
-All gears are case carburized heat treated & cryogenically treated & shot peened
-No extra cost for custom ratios, but comes with an 8 weeks lead time
-Non-custom gear ratio is close to stock

PM me for additional details to not piss off the mods

@Reaper, @Element Tuning, this may be a decent fix for your 4th gear issues.

Was just about to mention Reaper lol

I'm tired of keeping a spare transmission in my living room... Pmd for more info. :)

Me reaper and element I think are the most actively destructive drivetrain members. Haha

Hot diggity damn!

6th gear helical possible?

Ugh, I'm driving my stock brz with no turbo or anything but I am still VERY curious on how much that costs...can you pm me with the price too please? :)

6k before install

The hell is it made out of, adimantium?

Well, he's basically custom cutting five complete sets of transmission gears and that's it. If it were a regular thing with an established process in place then I'm sure it would be cheaper.

$6k isn't bad for a short run custom gear set.

Also, the S2000 did not come with an Aisin transmission. It's not any form of the AZ6. This is rather obvious when you put them next to each other.

It's supposedly a derivative. Case design doesn't really matter too much when it comes to their designations (L, G, W, R series transmissions each have variations that look quite different)


There's also been transmission shops that have torn both of them down and noticed the similarities.


Regardless, the AZ6 we have isn't the same as the other AZ6's out there anyway as it's also heavily modified.

I wonder how this will be to drive on the street. Ive driven cars with straight cut gears theyre a bitch.

It will be much noisier at very least, i guess.

Couple more details for you guys, some of which you already have:
-1st - 6th Straight Cut Synchromesh Gearset
-Shift and drive like standard with a mild whine. “Due to the way that we manufacture the outbreaks they’re not terribly noisy due to the accuracy”
-All gears are case carburized heat treated & cryogenically treated & shot peened
-No extra cost for custom ratios, but comes with an 8 weeks lead time
-Non-custom gear ratio is close to stock

For the longest time the S2000 wasn't on the list of cars:

From what I can tell of manuals, they're VERY different.

But, as you said, the big, important thing is parts interchange. Knowing what does and does not interchange is important.

Who manufactures this?

Gears aren't cheap to make even for the big car companies. Custom sets are gonna be pricey but how many transmissions will you blow through before you hit that price?

Keep in mind that a V160 new is $7K and that doesn't include the adapters and clutch to get it to work in this car.


If this can hold up to the abuse, it's really not that bad of a price...

Im not sure if theres going to be many motors that will break this or even come close. I wonder if there could be a possibility for a less expensive set. Not a complete replacement, but 1-4.

I guess in the long run this would be worth it but it's still pretty expensive. Glad to see stuff like this being made though, looking forward to seeing how it holds up.

I was so excited... till i saw the price...

Fuck that.... 3-5. :P

You likely wont have anywhere near enough tire to be damaging gears 1-2 on the street. Ask me why I know.

I would be all over it if I hadn't just heaped out money for turbo, custom oil cooling, and gauges... You know, if I hadn't just bought the very thing that's going to destroy my transmission and make me need this set.:burnrubber::cry::mad0260:

.

I will make it have enough tire. How does R888's @ 355 sound?:D

.

Good luck fitting that in the fender wells... Regardless it's not common to be putting heavy power down in the first two gears on a street car... Especially with only 2wd

....radials. That is my response, lol

So serious discussion.

I am considering this set, but want to know who is manufacturing it and what sort of support/warranty are they going to offer? Will they also throw this in a case for a core swap, or something like that?

Custom ratios would be ideal, I'd like to see a longer first gear and shorter 6th gear. What's everyone else's opinion on the gearing?

I really like this support,
Unfortunately because you are not an authorized vendor paying FT86 and advertising they will probably ban your account.
:(

They won't tell you, there isn't any, no and the stock gearing is fine its the fd that's wrong for a turbo car.

A steeper FD wouldn't really help with how short first gear is. It would help with 6th gear being as long as it is.

I like 6th. 70mph at full boost is fine.

Does anyone know who makes these gears?

Alright, back at it. Got some details worked out

The manufacturer is PAR Engineering.

Just ordered up my set for the RevvProjectBRZ. Super stoked to see how this turns out. For those of you on the fence, we will certainly be doing a huge writeup about the install / drivability / strength etc similar to all the other articles we've done. So I'll def keep the community in the loop!

Just really hope that this set holds the power! And from what I'm being told, there won't be any issues. "800 hp is ok. Remember its synchro, so must shift like a human and not a barbarian."

Ill be waiting

but thats the fun part :(

1-4 straight with 5 and 6 helical and dog engagement and you've got a deal.

Awesome, PAR Engineering is only a few miles from where I am staying when I visit the UK in 3 weeks. Guess who is stopping by to find out more?

This may be the wrong PAR Engineering. Dang it, I was excited for a minute.
