BMW ZF Getrag transmission into a BRZ mated to 2jz, ANYONE?
 

hello!

I was told by some supra guys that the BMW ZF 5/6 speed transmission is capable of holding 800ft lbs of torque. This transmission costs around $200-400 at any local junkyard by me so it's hard to ignore.

My question is, has anybody used this with the BRZ?

Also, I read somewhere that the stock BRZ trans is 34.5" from bell housing to center of the shifter, does anyone know if this is accurate?

The ZF trans is tiny and it's 30.75" from bellhousing to shifter center. This means some heavy modification of the shifter assembly will need to be done to "fit in the hole". Supra guys have no issues with fitting the ZF trans in the hole so it makes me wonder, does anybody know what distance the v160 trans is bell housing to center of shifter? This information will help me determine a lot of things going forward.

I am trying to avoid using the CD009 transmission mainly because I really want a 5 speed Getrag in this car. BUT, if this proves to be too complicated to complete in the BRZ then i'll likely switch to the CD009.

If I end up being the first one to do this i'll definitely make a thorough post of how it's done. However, it would be nice if I wasn't the first one though :P

FYI I bought this ZF 5 speed transmission today. 90% sure i'm going to be using it, i'll make sure to document everything required to do so for the BRZ. There's a small chance I will switch to the CD009 transmission but really don't want a 6 speed for this car.

Any update?

how come no 6spd? I've always wanted a 6spd lol all my previous cars only were 5 :(

6 speed is not good for 1/4 mile events and I don't care about fuel economy in this car. So the 5 speed makes perfect sense. If I change the rear end up, I should be able to trap this car at the top of 5th without losing any rpm's.

There are no updates yet, still trying to use the BMW ZF trans tho. I will be making a build thread shortly but really disassembly of the BRZ hasn't even started. Working on installing a lift first and ordering all the parts. I think the real work will begin sometime in January which is when my build thread will start as well.

I'm confused, how can a ZF be a Getrag? ZF is a company that makes transmissions. Getrag is a different company that also makes transmissions.

Yea you're right that's my mistake. It's a ZF trans not a Getrag.

Super bump! Can it be mated to the stock block?

They make an adapter for sure to do this. Looks up "collins ZF to 2jz adapter"

I meant the the stock fa20.

I feel like transmission swaps for the FA20 are non-existent. It would be cool to see something offered.

There's a CD009 swap kit...

Show me!

Lmbo. How did you not know this hahaha. I'm only intrested in the ZF transmission because I'm using an IRP short shifter which would bolt up easily to that transmission. And they are cheap to find https://www.mazworx.com/mazworx-favq...t-frs/brz.aspx

Thanks. Seems like the kit includes a lot, but still feels rich for me. I could probably find a used transmission for less and fab up most of the stuff myself.

That's over 3k for transmission adapting. Crazy.

Read the details, they have to machine the input shaft to make it work... it also includes the new driveshaft.

I'd bet you'd have a really hard time doing it significantly cheaper all said and done.


New OEM Nissan 350Z (CD009) transmission with machine input shaft
FAVQ Adapter bell housing already installed on transmission
Extended shifter assembly with short shifter
Transmission mount and crossmember
Crossmember to body mounts (requires welding)
Reverse lights pigtail
Carbon Fiber one-piece driveshaft

Yea it seems like a lot. It does include a carbon fiber driveshaft, short shifter with FA20 adapter, custom bellhousing, machined input shaft, custom mounts, etc on top of a brand new transmission. I wonder if they sell individual components.

You beat me to it. I got busy once I started a reply and never saw this post.

Here is the thing: a used tranny could be bought for under $750 easily, so that is on the high end to buy it new. The input shaft could be sold separately or machining could be as easy as taking off a quarter inch off the end—who knows? The mounts I could weld myself for cheap, but usually aren’t too expensive anyways. I don’t know the alignment of the CD009, so I don’t know if the extensor is needed, but the short shifter isn’t necessary. An aluminum shaft would be fine over a more expensive carbon fiber shaft.

pretty sure its including a brand new trans which is about $1500-$1800

I think prices spot on for what you're getting. If you have 15K to modify your car I stage one short block and this transmission and a budget Turbo kit would be great.

Correct. Carbon fiber driveshafts are over a grand, so $2500-3000 just for those two items. Mounts are usually under $500, short shifters are under $500, shifter relocates are usually under $500, bell housings are under $500, machining the input shaft is cheap, but there is the other $2k. The kit is a quality, new-parts kit, which is probably worth what a person is getting.

I was just saying a used transmission could be half that; an aluminum driveshaft could be done for $500; the short shifter could be omitted; I've seen transmission mounts for under $500, but I could weld up a set myself for much cheaper; I've seen adapter plates or bell housings for $350ish for other engine to transmission kits; I'm confused why a custom bell housing is used with an extension set, like couldn't a larger bell housing be used, so an extension set isn't needed? I could see saving some bucks and being just as satisfied with the finished project.

oh for sure. I've seen these engine/transmission adaptors done many different ways. I guess they could release an option for aluminum driveshaft in the future.

Ha! Labour to install a new input shaft would make that completely not worth it. Without knowing exactly what they're machining on it, it's hard to comment on what the cost would be.



You can't just keep extending the bellhousing or the input shaft won't reach the clutch disc. The custom bellhousing is used to adapt the transmission to the engine it was never built for, not for positioning it far enough back that the shifter lands in the stock location in the FRS/BRZ.

If they are already machining the input shaft then just replace it with a new input shaft that complements an extended bell housing so a complicated and large adapter isn’t also needed. Wouldn’t that be simplier? Input shafts aren’t very expensive. Obviously there are limitations to the length of the bell housing and input shaft.

I was confused by your first comment. How do you think they are machining the input shaft? I’m guessing they are removing it, machining it then installing it then charging for that time and labor, so what is the difference between doing the same with a used tranny locally? Better yet, I could install it myself. They could even offer a core exchange so the cost is just machining the end or just release the specs if they are feeling generous or someone could measure and tell everyone.

I'm going to go out on a limb and state that if it was really much simpler to do it that way, they would've done it. They have nothing to gain by making it harder and more expensive...



My assumption is they're machining it while the transmission is assembled and the input shaft is in place. Labour to tear down and reassemble a transmission isn't cheap (I've seen bills over $3k for replacing all the bearings).

Like I said above, they don't stand to gain anything by making it harder and more expensive, there's probably very good reasons they did it the way they did.

excited to see how this goes, i'm currently running an R154 and was looking to switch to CD009 after/if it gives up on me.

What they have to gain is creating a complete package that is less intimidating to buyers who don't want to source a transmission or aren't DIYers, and it also bundles multiple things in an all-or-none way, so they can force the purchase of the carbon vs aluminum driveshaft or short shifter. In fact, I could imagine them selling the individual components if I was to call or email them. Unless they were a set of parts that they didn't want to divide up, or if the components get shipped separately like from a transmission/machine shop and their shop. Who knows?

As far as the machining, unless they got a really interested setup or the machining is super amateur like removing an inch from the end and cambering the edge (a hack job) then my assumption is that they remove the input shaft. It shouldn't be hard to remove and reinstall like this generic example (there is a snorkel that needs to be unbolted/removed usually and then retention clips and basic stuff) and obviously the bell housing would be easy to remove:

The other savings would probably be shipping. Freight shipping a transmission versus shipping a bell housing or other components is probably much different.

With what motor?

2JZ lol

Just asking because there was recent conversation about an fa20 to cd009 kit.

I'll just leave this here (2jz to zf/getrag):

I found this kit for a 2jz to CD009. This seems like a nice setup like the Mazworx setup minus the transmission and driveshaft. $2800 for this kit plus $500 for an aluminum driveshaft and $750-1000 for a used transmission is about $4k versus the $5.6k, plus the extra cost to ship a whole transmission/driveshaft versus just parts. Not a huge savings, but a few grand is nice. Obviously, there is more work to be done, and the buyer has a used transmission and an aluminum vs carbon fiber driveshaft. Watch the video though, so you can check out the precision machining of the input shaft lol

The mazworx kit is $5k, not $5.6k. You're really only saving the cost difference of new vs used transmission, and you're getting an aluminum shaft vs carbon.


IMO, if you're deep enough into a project to need this that's a minimal savings at best.

The Mazworx is $5.6k when you include the Tilton hydrolic release bearing (+ more tax and freight shipping), which is the hydrolic release bearing that the other kit includes as well (apples to apples comparison).
