    6MT Master Swap Thread

    in Transmissions

    Posted

    Can't answer you "?", because I don't know what kind of rear end your running.

     

    Not that I know of as anyone try matting sti cup for the diff and stock lgt axel for the hub.

     

    If your rear end is a R160 (stock GT, LGT & 2.5i & WRX & sub model) or R180 (07 & ^ Spec.B & STi). Reread Post #1 http://legacygt.com/forums/showpost.php?p=2333430&postcount=1 That's answers your "?". What people used & works. When installing the rear end of a 6MT swap.

    When I was doing my swap, I talked to about the only people besides driveshaft shop that may be able to make these (locally) and they looked at the items and said it wasn't really possible, so if it was somehow, it wouldn't be feasible either. Spec Bs are the way to go.

    Cost of parts (if possible, new, since that's more consistent) and approximate number of labor hours needed to swap to a 6mt?

     

    Transmission including clutch assembly/flywheel, or do you need to purchase that seperately?

     

    I'm wondering because I've seen plenty of clutch jobs run $1500 for parts and labor, and it seems like this could be an option if it's $2500-3000 and you plan on keeping the car for a long time.

    Transmission Choice: 2007+ LGT Spec B 6MT, 2004, 2005 STI 6MT $2500

    Rear Differential Choice: 2007+ LGT Spec B R180, 2004+ STI R180, <2004 Legacy or you can use a regeared stock R160 as well with stock LGT rear axles $250

    Axles: Front - Stock LGT, Rear - 2007+ Spec B or custom Driveshaft Shop Axles $750

    Etc: DCCD Controller for STI 6MT $350, 2005+ 2.5i LGT Auto Driveshaft$50-150 (depends on the junkyard, dealer etc), appropriate 6MT flywheel and clutch I picked up a stock STI flywheel for $25 I think, then a SPEC 3+ clutch package for $750 or so I think.

     

    Add labor on top of that if you're not doing the job.

     

    So lets say I were to go the route of an 05 STi 6spd for my 05 Outback XT.

    The outbacks have an R180 rear diff with a 4.444 final drive gear ratio.

    Would this be compatible? There is an 05 STi at a salvage yard not too far from me that is nearly complete available for partout.

     

    You'll still need the STI R180. It's not that its an R160 or an R180 but rather the gearing that is important. The STI and Spec B R180 are a 3.9 final drive, which is what is required for the STI swap, so you will not be able to use the outback's stock R180. You may however be able to use the axles, if you do the swap, you can take a picture of the axles and I'll be able to tell for you, I think there is a pic in Hammer's thread from my swap comparing the Spec axles to the stock LGTs.

    Which 6MT has a taller gearing? Is it the 2007 STi?

     

    Yes.

     

    Groff, very nice..

    FYI to everyone else, all this information was gathered by HAMMER DOWN, myself and groff, during our swaps.. this is real-world info, not speculation.

     

    for the rear diff:

     

    hammer down is running a re-geared WRX unit

    i am running a 2004 legacy auto 3.90 (just broke it :spin:), so i am swapping the 05 LGT LSD carrier into the 3.90 legacy housing

    and groff is running an R180 and Spec.B Axels. (damn you! :lol:)

     

    yea, sorry, didn't have any shout outs :lol:

    Now how about swapping a 6 Speed into a 5eat :)

     

    A little bit more difficult, but still doable. you'll need all of the above parts plus the clutch master cylinder and a new pedal setup (I'm guessing since the brake and clutch are on the same rotating assembly under the dash). will probably also need a new trim piece inside the cabin and shift boot :p. You'll now also need the 6MT transmission cross braces I would guess.

    There are basically 2 main options for turning your 5MT into a 6MT.

     

    Option #1:

    Transmission Choice: 2007+ LGT Spec B 6MT, 2004, 2005 STI 6MT

    Rear Differential Choice: 2007+ LGT Spec B R180, 2004+ STI R180, <2004 Legacy or you can use a regeared stock R160 as well with stock LGT rear axles

    Axles: Front - Stock LGT, Rear - 2007+ Spec B or custom Driveshaft Shop Axles

     

    Option #2:

    Transmission Choice: 2006+ STI 6MT

    Rear Differential Choice: Stock LGT R160

    Axles: Front - Stock LGT, Rear - Stock LGT

     

    Etc: DCCD Controller for STI 6MT, 2005+ 2.5i LGT Auto Driveshaft (for Sedan or Wagon based on what you have currently) or 2007+ Spec B Driveshaft, appropriate 6MT flywheel and clutch, 2005 STI front axle seals (recommended), 6MT shift linkage, 6MT shifter, 6MT shift knob (as a note, most donor sets more than likely won't have a knob as most have been robbed from the junkyards :lol:), 6MT slave cylinder, 6MT clutch fork

     

    Quick Pros and Cons to the different components:

    <2004 Legacy Differential is not going to be a viscous limited slip (CON)

    2007 Spec B 6MT does not contain a limited slip front differential (CON)

    2006+ STI 6MT has a 1:1 stepper center differential which allows you to use your Stock R160 on the 07+ cars, if you use an 04-05 STI trans.. the GT 5MT came in 2005-2006 4.11FD 2007-2009 5MT 3.90FD (PRO - Cheaper CON - weaker rear diff if using the R160)
