Default ? Part #: Turbo Legacy Tranny

I am trying to locate a Legacy Turbo Tranny that is in good shape. I was thinking of trying to order a new one but I don't have the part number.

Does anyone have a clue as to what it is?

Thanks
Brad

Don't know what project you're working on, but have you thought about a used WRX tranny?

I am actually interested in both but figured I would ask WRX Tranny questions somewhere else.

My project is to swap the 3.3 litre Flat 6 from an SVX into my Legacy and use the manuel tranny from either the Legacy Turbo or a WRX.

I am still in the planning phase as this project is about a year and a half from completion.

I will be collecting parts as I find them to spread out the cost for one. Also nice SVX engines and Manuel Trannies don't fall out of the sky all at one time.

Anyone have an idea of a tranny that will be strong enough to handle 300hp and similar torque that has a similar bolt up pattern as Legacy/RS trannies?

Thanks

That sounds interesting...but why the SVX motor? Why not use the newer H6?
As you point out, SVX motors don't fall out of the sky. How robust are the old 6ers? There is a local wrecker near by that has a few of the SVX motors.
Either way, make sure you take lots of pictures to document the whole process.

Good Luck.

The Real Oaf:

from what I understand, the newer 3.0L H6 uses entirely different mounting points than the ej series engines, whereas the 3.3L H6 uses almost identical mounting points, making the installation "a little" easier. The newer engine has a little bit less power (215 vs. 235hp).

MY 99 2.5GT: Have you considered getting a hardened gearset as opposed to a new transmission? The cost might end up being a little more, but if you go with a gearset like MRT, they'll replace the gears if they end up failing. Besides, I'm not quite sure the turbo legacy trannies will hold up to those torque levels (I'm almost positive the wrx tranny will not).

This is just speculation from driving my mom's now deceased svx from back in the day. Those things put out some massive torque from 1800rpm on. I suspect you'll be snapping wrx gears like there's no tomorrow.

Just a thought.

The 3.3 is a great engine, though it's big and complex, but it should bolt right in and uses the same transmission as the Legacy Turbo.

Either the WRX or Legacy Turbo 5MT should work, but the WRX is going to be better if you're going for 300hp, as it's case design is much stiffer and everything should be stronger. A lot of the Cobb Stage 1 and 2 cars are running 250-320HP with few problems.

If you're really serious, and you can swallow a little pride, get a Legacy Turbo or SVX 4EAT and send it to Level 10. $3600 later it will be the fastest shifting, strongest transmission this side of an STi 6MT. I'm dead serious.

FWIW, the Cobb Tuned imprezas are running 280-320hp off of the 2.0L engine, which puts out significantly less torque than the 2.5L turbo, much less a 3.3L with mods which allow for 300hp. From what I hear, torque is what breaks the gears, not hp.

I would personally rather risk breaking an "unbreakable" MRT gearset, and have them send me a new set of gears, rather than risk breaking a wrx or turbo legacy gearset, and have to shell out more of my money for another tranny.

But that's just me. To each his own

Default However . . .

DLC, you are right about the auto tranny being able to hold up to more torque than the manual trannies, especially after having it modifed by Level 10.

Update: This is verbal info.. I havent measured...

I was just at FS auto in CT.. they are a big time subaru dismantler.. and they basically said the H6 SVX WILL NOT FIT. There is an issue with the firewall and with the overall width clearing the strut towers...

this is verbal from two different guys there. Yes, it bolts to the tranny, but other than that.. the 3.3L is a no go.

Until I get actual measurements, i wont GIVE UP yet, but I am highly questioning if my investigation is worth it

Did I mention that I am in contact with Forced Air Technologies who is in the process of completing a 3.3 swap into an Impreza? Sorry if I didn't.

The reason I plan to use the 3.3 is:

1. More Power and Torque then the new H6
2. I know a Subaru Tech who told me to stay away from the complex gadgetry of the new H6. He said there is so much that could go wrong with that engine.
3. Mount points as stated above
4. I did say 3.3 H6s don't fall out of the sky but its way more likely that I would find a 3.3 rebuilt or in good shape at a junk yard then a new 3.0 6. Pretty much my only option for getting a new H6 would be going through Subaru. For that price I may as well buy a turbo kit and new tranny for my EJ25.
5. Stock the 3.3 litre SVX H6 is bullit proof for boost up to 5psi. No electronics needed.

I considered a low boost turbo setup for my EJ25. I did some figuring and for the same price as a 8-9psi intercooled turbo system with a TEC-II I could transplant a 3.3 H6 with tons of torque and use the Forced Air Tech 5psi turbo kit with an SAFC and get around 320 hp with tons of torque. I think the H6 is a much better option then an 8-9 psi setup on the EJ25.

Here is the link . The yard is in Racho Cordova, a suburb of Sacramento.
They have a wide selection of parts, and even a few SVX's. They like to play the "half of new" price game...so barter with 'em.

Real Oaf: Thank you for the info (and link) on the Subaru auto dismantler.

MY99 2.5GT: Good luck on you heart transplant project. Keep us posted and let us know the ins and outs, ups and downs as you get further along. I'd like to do something like this with my 99 Legacy 30th Anniv L Wagon to replace my 2.2L.


Happy New Year to all of you and yours. May 2002 be everything you hope, want and need.

Best to all, Dale
