Converting a Subaru STI 6 speed for Mid-Engine use 

Thanks for your review and comments, we've taken them on board. Double checked that all lockout holes are reemed to 13mm. We will include the shift rod seal and nice hardware bolts with future kits.

Bro I have watched all of 26 seconds of this video and am already subscribed with all notifications. I know immediately several facets of your character, from the line "I am building an Auto union type C replica." Clearly you have substantial skill, or Interest and willingness to learn. You understand that all of these machines regardless of how exotic were built by man, and as you have the same human capacity they do are able to solve any problem through research and resourcefulness. And you have an appreciation of the historic significance of this vehicle. You haven't even pitched the "like, share, subscribe" line and I have done all three. Please keep the project updates coming!

Curious how this holds up. Transmission gears are rated by how much torque they can handle, not horsepower. Did you confirm with independent sources that the STi transmission will hold up to the much higher torque? Of course, it's the torque through the transaxle, meaning that if you use skinny tires, it'll hold up fine. OTOH, using sticky slicks and it'll probably grenade at the first clutch drop. I highly suggest talking to people who don't have their hand in your wallet regarding transaxle selection. There's a reason why transaxles rated for V8s and such are well over $10K.

Awesome. Ive got a jdm automatic sti tranny that i want to do this to. Hope the back and center diff section is the same.

It makes me wonder if you could take a fwd transaxle and convert it to a rear engine rwd

Have you ever done a automatic transmission out of a 2005 outback before. Or know anyone who has?

You sir, are a God send. I occasionally do work at the Porsche dealership and there is an all but abandoned 986 Boxster that I have been really contemplating about buying but that 5 speed would grenade the moment I swap anything more powerful than the 2.7 in there. I even looked up a few years ago if this could be done but nobody could give me a straight answer. You may have solved all my questions. Subbed!

I live in Australia we do have 1/2inch drill bits

Great video. Will be paying close attention to this project. What year/model vehicle does this transaxle come from? Instead of reaming out the hole, it would be possible to turn down the part in a lathe to fit the new back cover.

Few companys doing this in Australia, these guys are not the first to design this, price is bs,...

Personally what i thinks happened with that hole is they used an old reamer bit to drill it since they eventually wear down and become smaller diameter especially when working with aluminium since aluminium oxide is used as an abrasive so it kills them quicker

Nothing like the smell of gearbox oil, on your clothes, shoes and under your nose where you wiped your face 😂

Props for the Elbonia shirt. =]

I had never really thought about it the drivetrain was any different but I guess being that they are AWD instead of 4wd they don’t have regular differential setups. I guess I had just figured they had a front rear different up at the axels. I hadn’t ever imagined that the differentials were basically integrated into the transmission package. Guess it makes sense for rally driving where you’d want as much clearance as possible and saves the headache of trying to shoehorn a differential under the motor and between the bulkhead for the independent suspension setup. I’ve been seeing the guys taking the square body Chevy trucks and running them 4wd with a LS engine and they obviously hook up amazing on some of those shitty streets. I was thinking about how you’d go about getting the front gears and all that and the ground clearance on the lower cars but if they were able to be located into or near the transmission setup that would make a much better install. I’ve been debating on trying out a AWD/4wd 99’-04’ mustang with twin 70mm snails and a newer L8T engine swapped. That’s the new bigger gas engine from the Chevy 2500s it’s an Iron block LT based engine that’s also a 6.6L and like all the engines in that family all the Corvette/Camaro stuff is interchangeable so you are getting a nice little jump up from the 6.2L aluminum based blocks

Considering where the output shafts are on the front diff, the crownwheel must be farking small!

You have to do a follow-up video of the mid engine car when running.

Great job so far! What’s the latest on your project?

$1100usd is a lot considering you could buy a tig welder for less and simply use parts you already had like I did. Nevertheless good work and a good video 👍

And No instructions

Pretty sure this is a legacy gearbox, more or less the same as the STI box

wow that Mr. Sark shirt is a blast from the past! love this build too! cant beat a v12 and a 6 speed proper trans!

can it be used with 2jz?

great video thx for this

1100usd gees thats steep

Good work 👍

How much hp can it handle after this conversation.
