I think some of those "Sti" versions were more about the bushings than the metal. I agree with KZJonny, if they look the same, I would just keep what you have depending on the bushings.

Nice, I teach Computer Science with some engineering department neighbors. They are building a baja cart program that I really wish I had the time to help with.

I looked through the Cusco guides to see if I could find an answer for you, half of them didn't have torque specs. It's into aluminum; so snug, but not too much...

Yes, for the Legacy GT 05-06 is 4.111 and 07-09 is 3.900 for the rear diff. You can check on cars101.com or https://rallispec.com/downloads/Transmission ID Chart_Public.pdf If the WRX diff is different for the axles, get a 05-06 LGT rear diff, it's still 4.111 and matches your axles.

I think it's 2015+ for the WRX It's essentially a 6mt in a 5mt case, which is why you can use the same clutch, fork, ToB, driveshaft, mounts, etc.

If it's been a year, I'll be surprised if the rear diff doesn't match and the transmission survived this long. I would guess you'll want/need a new pivot ball and fork from a GT to match up with your Exedy clutch.

I can relate, my first car work was mid-80's mustangs. But I've been working on Subarus for over 20 years now and have gotten used to them, they are actually really nice to work on compared to a lot of others.

Yeah, I think you have proved that you can't assume anything was done right, and need to verify. I may have a GT clutch fork if you need one, I should also have a 4.11 rear diff if you end up needing one. It should be cheaper to get a rear diff if needed, but you may want to consider getting an LGT 5mt that you know the history for vs this NA forester 5mt that is a bit unknown and weaker. Really depends on what you plan to do with the car and for how long.

Also, looks like the clutch fork for the NA Forrester is different than the '09 LGT. 30531AA180 - '09 LGT https://parts.subaru.com/p/Subaru_2009_Legacy-25L-TURBO-5MT-GT-LIMITEDOBKXT-SEDAN/Clutch-Fork-Clutch-Release-Arm-Lever-Clutch-Release/49239192/30531AA180.html 30531AA220 - '06 Forrester https://parts.subaru.com/p/Subaru_2006_Forester-25L-MT-X-LL-Bean/Clutch-Fork-Clutch-Release-Arm-Lever-Clutch-Release/49239193/30531AA220.html If you look at the ToB for each respective transmission, you can see the differences: 09 -LGT ->https://parts.subaru.com/p/Subaru_2009_Legacy-25L-TURBO-5MT-GT-LIMITEDOBKXT-SEDAN/PB001902-Bearing-Clutch-Release/75434842/30502AA121.html 06 -For ->https://parts.subaru.com/p/Subaru_2006_Forester-25L-MT-X-LL-Bean/Bearing-Clutch-Release/68011735/30502AA150.html I would guess the LGT fork is wider/beefier as part of the reinforced transmission stuff for the turbo.

Not that I know of from the outside, but there is a post on subaru outback forums of how to test it. https://www.subaruoutback.org/threads/identify-rear-diff-gear-ratio.40541

You are working on a '09 GT w/ 5mt, right? TY755VC7AA shows as an '06-08 Forrester transmission, with a 4.10 final drive. https://rallispec.com/downloads/Transmission ID Chart_Public.pdf The original transmission for an '09 LGT has a 3.90 final drive, so you need to source a matching rear differential or it'll destroy itself due to the mismatch. https://www.cars101.com/subaru/legacy/legacy2009.html The GT 5sp is reinforced compared to the NA 5sp, but I'm not sure how much it is; it's just more likely to break than a GT 5sp, just not sure at what point it would. Related to the clutch, my search for exedy 1504 clutch is showing that it's for a Toyota Yaris. Did you mean 15804? That would be for this transmission (or should be). It looks like they are expecting a little bit wider fork there, still trying to research why there is a mismatch. Is that the original fork from that transmission or where did the fork come from?

I've still got it, what might you need?

Yes, the engine is out and available. Where are you located and what do you need?

Any chance you got logged out on the mobile browser? If you are still logged in, then it might be related to a status change on your account. I don't know of any event that happened, that's beyond the realm of moderators.

I may have one in my part out:

Most likely. You might be able to inspect and reuse the bump stop and dust cover, but I would plan to replace the mounts. They have seen a quarter of a million miles, this would likely be the only time you would have to do this and they are tired.

Fairly certain that after 30+ years you're going to have to find a transmission, not sure you could have found that part 10-15 years ago even. Not sure where you are, but I have a rebuilt Phase 1 4EAT w/ 60k miles on it chilling in my garage.

My spare set of Cusco brackets are 4.8mm. I would keep an eye on the 2mm; it might be fine, but there might be a good reason the others are near 5mm thick.

Someone updated the Wikipedia article on April 11 to mention an internal email stating that 2025MY will be the last for the Legacy. https://en.wikipedia.org/wiki/Subaru_Legacy

I have a set of stock injectors, but they are the side-feed style from 05-06, you need the top-feed style. There should be folks on here with spare stock top-feed injectors.

Those are plates needed to attach the end links for the rear swaybar if you are running JDM aluminum trailing arms. USDM has a built-in mount point.
