Impreza GC8 5MT DCCD: swap whole tranny vs just the transfer case

It's more of a tranny question but then again, if I'm going down just swapping the transfer case, it would become a conversion.

All 5MT DCCD tranny has a different type of clutch than a USDM 2.5RS 5MT. There is really no way I can sell off my old tranny without taking a big loss so I might as well treat that as a write-off (same for the old transfer case). Don't think the transfer case is interchangeable between 5MT and 6MT as many 6MT owners don't seem to want DCCD even though they have a DCCD tranny (those come by a lot more common than non DCCD tranny, exactly the reverse scenario for 5MT).

1) If I swap the whole the tranny (seems to be the easiest), I need a new clutch but is there anything else I need to do? This is probably the most expensive option as well because a) I get zip for my old tranny and b) shipping a tranny is ugly across the border. Besides, I wanted RA gearset but with a much lower final drive for highway cruising

2) If I swap just the transfer case, I get to keep my tranny (which I still need to rebuild with RA gears) and my fairly new clutch, but where am I going to find that and at what cost?

My goal is to have RA gears with highway friendly final drive and DCCD. Even if I swap the whole tranny I would have to break it to change the final drive which makes swapping transfer case a feasible option (if I can source the parts that is). Ideally I would get an RA tranny that has the front helical as well. Either way looks to be expensive but I want to see if junking the clutch is worth it when I have to break out the tranny in both cases.

Fire away with anything related, thanks

if i were you i would do the whole thing. i have never seen a transfer case for sale alone and even if so in my opinion you should just get a 6 speed. the 6 is great for highway because you can drop it into #6 and get great gas milage. also i just got a motor from canada (in live in the states) and it was not any trouble getting it accross the boarder, i dont know about the other way but i think it would be no different. oh and if you want a tranny call sunrise japenesse, they are in montreal and can get you a very nice jdm tranny, and no boarders.

Canadian customs are pretty anal about stuff coming in and takes forever, plus shipping large objects over is crazily expensive. Thought about 6MT but thought better of it - on a GC, once the 6MT goes in, it comes out the next time you need clutch/flywheel work. If I only lose my clutch when I drop a JDM tranny in, that might be the only option since transfer case don't come in by itself.

borrow a truck and make a trip across the border, pick up the 6MT and drive back.

Personally, I prefer the 5MT
<---- Check the location and maybe you can tell me how far I need to drive to get that 5MT RA DCCD. I figure by the time I'm done with this route it would be close 7-8K USD in total cost

Cross-border is not that bad. My clip arrived in under 2 weeks. You can also try JRP in Toronto. They stock JDM motors and trannys.
Why go to so much trouble for better gas mileage on the highway? If you increase your mileage by 20% (which you won't) you save $300/500 per year. If you have a lower final drive, acceleration suffers across all gears.
Suggest getting a 5spd RA/R with DCCD and 4.44 diff and Exedy street clutch. Should run less than $4kCdn plus installation. The $3k you save will buy all the Sunoco 94 you ever save from the lower gear ratio on highway cruising. Of course you will fail on the one tonne challenge.

Actually, I drive quite a bit of highways on my daily route to work. I'm trying to see what RocketRally can offer me since they are local - I don't have the space for a tranny and thus prefer to have a shop locally that can source it and have it installed. I'm filling up every 5 days on average and my tank last about 400Km. Please tell me where I can get the RA DCCD 5MT w/Front LSD and clutch for less than $4K CDN on the west coast...

A friend of mine was negotiating for a 5spd RA non DCCD/LSD for $1500Cdn from Singapor. Cheaper to ship to west coast than Ontario.
Talk to BSC on the toronto-subaru-club.com (Joe) he might be able to broker something for you. He has a V8 tranny for sale right now, but that one will likely be more bucks as it is newer and 6spd.
I can get 400 kms on a tank on the highway if I keep under 120km/h.

I think I would have accelerated right past it on 3rd
$1500Cdn for a 5MT RA non DCCD... good job for your buddy there - I wish I have that kind of connection. It cost more than that for a set of RA gears (which I believe would be new)

Nothing special about his connections. He is just networking through various contacts.
He declined this tranny as he did not want to buy it sight unseen without a warrantee. It is risky buying used stuff for sure, but vastly less expensive because of the risk.
The guy who did my conversion has done lots of them. He feels confident enough about the JDM clips that he warrantees them. There is some good value out there because the Japanese cannot use salvage parts like we can so they just dump all the good parts on the overseas market for pennies. Clips with less than 60k km are common. It comes down to having sources that can be trusted.
I get my speed kicks on the track now and don't feel the need to light up the highway anymore. Keeps my insurance company happy too. My other suby does the long haul trips.
