so if i find a legacy rear end, all i have to do is switch over the wrx internals, and get the ring gear from the legacy pressed on to the wrx lsd rear. sounds easy enough. what year legacy do i have to get the rear off?.
oh and is the legacy rear a r160, or an r180? if so do i have to change the axles over, or can i use my stockers?
so many questions, so little time..
by the way, if anyones selling a 6mt, i am interested, so let me know.

Yes, it is that simple. And, to your surprise, you only have to bolt the ring gear in, not press it! Just use some good locktite ln the 5 or 10 bolts.
I am not sure of the year of the Legacy diff, but I will find out ASAP for you.
They are both R160, no axle changes required...no worries. I just bought a complete R180/Axles/Hubs/Brembo setup, that is why I am selling my rear undercarriage.
Hope my info helps.

Where do you get this stuff
BadWRX
Where did you find out about swapping? How much does it cost if you aren't a mechanic (if you dont mind telling)? You said its and easy bolt on/ swap but where does 1 find the parts to do it? How is the performance of the 6MT? Any problems that we should know about?

Where did you get it and how much? Is this gonna be as easy a swap as your old set-up?

I'm also interested in this swap and money wise.
I'd love to drop 6mt in my 03 wrx.. Besides all the advtages it also can use another gear too for highway driving.
thx

Hey Imprezer
Thanks for all the info but could you by chance tell us where to get the 6mt and all the parts if we wanted to do a swap?

Does anyone know the length difference between the the Sti rear axles and the US OEM sedan rear axles?
Also, is there a difference in the spline diameter and spline count?
Does anyone have a copy of the Subaru parts catalog on CD that they wouldn't mine burning a copy for a fellow WRX enthusiast?

Hmm, I seem to recall that the 6MT ratios were more tightly spaced, but that 6th gear ended up being slightly less overdriven than 5th in the 5MT. I just can't remember where I might have seen this, though... sorry. The 6MT's chief advantage is strength and durability, not necessarily performance. It's a tough *****.

I am assuming that if you have to shift 3 times with the 6MT and only 2 with the 5MT, that the lighter 5MT package would be a better choice for stock 0-60 speeds. As you upgrade your stock engine to overcome the shifting delays and added weight, the 6MT would be a more sensible and reliable choice. I've never driven a 6MT though and don't know that you are truely forced to shift into 3rd to make it to 60mph.
With that in mind, I would love to know:
- Est. price to purchase parts required to do the 5->6 conversion without mods to the car or the parts.
- Est. price to sell old package. (Would love to trade with a cash-starved STi owner who wants a better 0-60)
- Does the 6th gear improve the situation with the 5MT's 5th gear sucking gas at freeway speeds?
- Does the entire package open the possibillity of installing that variable center diff. controller we've seen in the new STi pics?
- What is the weight change from 5MT package to 6MT? Est. is fine but if you have the parts, and a scale.. ?
That's a trickey list but the first person who could nail all the Q's would likely have some customers who, at the very least, could be refered to a friend's garage.

It will cost you far more than 3k
I would estimate 12hrs labor plus parts
parts are hard to guess I have seen DCCD trans go for 5500
And about what rear ends that can be used for the swap ALL subaru r160 rear end that Is anything that is 4wd but I don't know about SVX rear ends
not that you are going to get a svx rear end for a good price anyway.
the older cars had stub shafts that go to the half shafts the new ones don't have these stub shafts but as long as you are going to use your carrier they do not matter.
Note the side plates should be changed along with the carrier and contact pattern along with backlash should always be checked when you are playing with ring and pinon gears
