All You Need To Know To Put An STI 6 Speed In A Legacy GT!! 

Perfect timing!

Same here!!!😂😂

What about 08-09 legacy spec b it has dccd

To my knowledge none of the spec b came with a dccd. They are just a 5050 6 speed

@@SWSpeedCo my 08 legacy has dccd

Thank you!! Glad you enjoyed it

Thank you!! Good luck with your build as well. I think some polyurethane shifter bushings would work good to stiffin things up for you.

Yeah, gathering all the parts is pretty time consuming.

@@SWSpeedCo I imagine it costs a bit all considered, even without the transmission.

Yeah I think In total it cost me 10k give or take. Can definitely be done for cheaper if you source used parts

Nice but I paid for it lol!

Specifically, the hybrid legacy rear drive shafts that go into the r180 rear diff to 5 x 100 hubs

Sorry for the late reply, the part number for the rear axles is 28421AG03B

From my understanding the 2007 is the cheapest 6 speed to buy new and it has the helical front LSD as well as the 1:1 torsen center diff which is the best combo for going fast.

What’s the vast sensor?

Very cool, I would not be able to tell you a parts list for that car as I don't know myself. I would try looking on the legacygt forums to see if there is any information out there.

Good to know. What if I wanted to use Spec B. axles?

Six speed swap I'd done, haven't had time to edit and upload, been very busy recently. I had to put the car back to stock to get it inspected because I got a state ref ticket. But i will be back😎 Thanks for watching!

The part numbers for the spec b shift linkages are 35041AG020 and 35031AG020. All the part numbers are in the forum post I linked to in the description. Glad you enjoyed the viseo. Thanks for watching!!

@@SWSpeedCo THANKS

@@SWSpeedCo It looks like 35041AG020 is indeed only for the spec.B, but 35031AG020 is also on a bunch of 2008+ STIs (maybe only omitting 2011 for some reason?) and 2015-2021 WRXs. Both parts appear to be in stock again!

Did you do a radio swap?

It seems like the swap has been done before so it's possible. The process is more than likely very similar, but as far as what peripheral components are needed to make it work together I am not sure. I would recommend looking at some forum post to see what others have done. Hope that helps!

Exactly the same!!

Yes, the legacy and outback are basically the same chassis just that the outback has a body lift. Other than that they are the same and this combination of parts would work on a legacy as well

@@SWSpeedCo That's what i guessed, but i wanted to make sure. This is a list of all the parts you mentioned in the video and if you can can let me know what i've missed that would be helpful. - 2007 STI transmission - 2007 STI rear LSD - spec.B rear axles - LGT front axles - rear STI differential mount - clutch setup - reverse lockout - shifter for a spec.B - transmission crossmember for LGT (or is that only needed for the outback?) - STI 6-speed transmission mount - spec.B shift linkages (or add .38 inches to STI ones) - driveshaft from 4-speed auto legacy with r180 flanges instead of the r160 flanges it comes with - spec.B clutch hose

So it can be any year sti rear diff from 2007 to 2019 I think. As long as it has the correct final drive. The lgt transmission cross member was just for the outback application. For the rear diff you are actually removing the r180 flange and putting an r160 flange on the r180 diff so that you can use that driveshaft. Or you can buy a spec b driveshaft and it will bolt up to the r180. Other than that looks good, hope that makes sense.

I think they are as strong as the 5 speed transmission. They have the same split case design as the 5 speed so they flex a little bit. Probably around 350 whp. The sti 6 speed has thicker gears and a one piece case which makes it much stronger

I'm not sure if that would work. It may be possible but what I do know is that a dccd is about 3500 to buy on its own so at that point you may as well buy the sti transmission.

I'm not sure, you will have to look it up on the forums. I haven't heard of it but I'm sure there is a solution out there.

I dont think sti hubs will bolt up to the legacy suspension. To my knowledge the spec b axles are your only option

@@SWSpeedCo I will do some research and if I find a way around it I will return to let you know.

Thanks, I would be interested to hear other methods

I haven't tried it yet, currently acquiring funding. But i believe if I get a set of coilovers meant for a STI, they should from all I've read work, and allow me to do a 114 swap easier and allow me to possibly use sti axels depending on length. If that wont work i understand, there is very little information on doing a hub swap on a Legacy. If all goes well I might start posting my progress on my 2nd gen.

That's about right probably a little more. I try not to pay too much attention to that sort of thing now lol

I just accept the fact as law that if you want your car to be fast and reliable, it won't be cheap. The game is the game.

LOVE FOR SPEED HAS NO PRICE TAG

I didn't have to touch the ecu for the 6 speed swap. I have never tuned an automatic car so idk what the difference is.

I'm not sure but I can't imagine the length difference would be that great

The spec b does have not a Driver control center differential (Dccd)

I dont think the subframes would match up but I suspect the transmission would work, might need different driveshaft and rear axles too

If it says they only fit spec b and no other cars they may be the right part. From my experience though aftermarket or remanufactered axles from parts stores don't hold up very well

No its a completely different platform

NOPE

Yes, the swap is done! I've been very busy with school as I'm trying to graduate this semester, so I haven't had time to edit the videos yet. I will be done with school in a couple weeks so you can expect the video around that time hopefully!

I dont think the rear has circlips on the axles. The one I pulled out of the r160 didn't have it, and the new spec b axles didn't come with circlips and the still locked in. I think you might just have to seat them In better. And I got the rear diff used from a guy who parts out stis. It came from a 2015 sti. All sti different from 2006 to 2021 use a 3.54 rear diff so you can get them from any new sti

When I install axles I put them in the diff or trans side first and kind of use a slide hammer like action with the axle and a couple of pushes and you can feel it click in

@@SWSpeedCo when I give you $1500 AND 7 days (when you said you can do it in 2) to do a swap you've done before and the axels aren't locked in, and, AND you admit you fucked up, it's gonna cost you to either take the diff apart and put the circlips in the diff or buy and install another/new diff. Oh, and did I mention I discovered his "oversight" 2 days AFTER I drove 330+ highway miles back home? Consequently, I've not driven it for real cuz there's no diff dip stick so idk how much oil is left in it or the rate of oil loss and I refuse to get my hands dirty to find out cuz I spent clean $ AND rented a car (2020 OBXT; turbo that takes regular and the hands free "eyesight" feature is DOPE!) for a week for $304 to have the swap done minimally correctly. In fairness, the kid KNOWS what he's doing which further compounds my pissedoffedness. Yes, I'm a professional wordsmith, don't try this at home without proper safety precautions in place.

That's wild, 1500 isn't bad for that kind of swap but idk why he said 2 days 😂. I hope you get everything figured out.

@@SWSpeedCo he's a professional mechanic; shop with 2 lifts, ALL the tolls you can imagine to fix cars and he's done it before. It's not a very hard thing for him to do vs what it would take for you or I to do and a lift makes ALL the difference. It took him less than 15 mins to change a front wheel bering, start to finish. He had $ tied up in the parts so he was "motivated" to get his $ back so he made $100+/hr and had 7 days to do so he procrastinated. It's gonna get straight but it's gonna be a PITA and that's gonna be factored in to his cost.

I'm not 100% sure but I think so

@@SWSpeedCo how does the wring work, the sti transmission harness plugs up just fine?

There is an adapter harness I got from iwire that adapts the 6 speed wiring to the 5 speed plug into the factory harness and that was just plug and play. I also got an iwire DCCD controler which also plugs into the 6 speed harness but is a standalone unit so it doesn't connect to the rest of the car. I will have the 6 speed videos out soon I just haven't had time to edit and upload them.
