Help me source parts for a 5MT dual-range swap

Recommended Posts

Hi,

 

I've been googling like crazy for the last few days, but I'm far from well informed.

 

The car is a 2000 Outback with an EJ252 (8 bolt) motor.  As far as I can tell, an appropriate tranny would be a TY754XKAAA or pretty much anything(?) with an 'X' as the 6th letter.

 

What's the deal with D/R ratios?  That tranny above would have a 1.19:1 reduction, but the gears from an early EA82 mated tranny is 1.59:1 (?) for a serious drop for the extreme I'm looking for but won't fit without machining? Or buy ready-to-go gears?  Or drop the bucks ~$3900 for a fully prepped one from All Drive Subaroo in Australia with a sizable shipping charge?  Texas JDM has an unprepped tranny for $900

 

Then there's the AU interior console for the range lever and maybe a dash indicator if I want to get it all OEM.

 

Quaife ATB or Torsen diff?

 

What have others done?

Custom gears or its not worth it. Ea trans will work with enough swapping around. If your looking for a crawler, Subaru wont do it for you, no matter how much you spend.

 

Japan got the DR too so they can be obtained, but shipping big things from Australia is about impossible. Very little trade between north America and there. Boxable parts that can be shipped via normal channels are no problem. You can find the console and stuff easy.. You'll be into it $2k for .19 reduction

Just get an outback with an automatic. You will be disappointed when someone in a Forester auto wheels circles around you. The torque converter IS a low range when it's not locked. Also no clutch to wear out, smoke, stink. Trust me this isn't what you want.

Lol. Get a Toyota truck if you want low range. The Subaru low range isn't worth beans. I've had dozens of them. My lifted hatch has a Nissan transfer case in addition to the Subaru 1.59 low range. If you want to wheel in a Subaru you either do it with a truck transfer case or you get an auto. End of story. 1.59 IS NOT extreme. 4.00 is extreme and a lot of the Toyota guys run 6.00 and double t-cases.

 

The auto also can be locked into 4WD. The manual cannot. It's a better, smarter, longer lasting transmission. And it's real 4WD not AWD with a visco coupler that will also fail on you. The center diff for the AWD 5 speed is a very common failure - they are $586 from the dealer.

 

Do the math.

 

As you said - you are FAR from well informed. Well I am well informed.....You're about to do it wrong. So now you are well informed too.

You got it wrong, I don't want rock-crawling.  But you go ahead.  You need that drop for those tall tires. I want just good overland.  I'm only planning a 2in lift or so with stock sized tires.  I'm not going for this

 

 

Maybe.. Just maybe good enough for the Rubicon trail, but that's not my goal.  Should it be?

Hi David,

I'm Isaac from ADS, I'll be helping you sort out your dual range enquiry to suit your
Outback.
We currently stock 1.447 and 1.196 ratio dual range gearsets. We are expecting delivery
of our billet 1.6 high-low sets early next year, but we have no confirmed delivery date.
There are several ways to immediately meet your needs with existing stock; either a
complete gearbox assembly minus center diff, or the loose gearbox parts required to
convert your single range to a dual range.


Option 1 - non assembled gearset.

The non-assembled gearset conversion kit includes all parts and gaskets you will need to
convert your own gearbox to dual range. You will need someone with some knowledge of
Subaru gearboxes to perform the disassembly, assembly and installation.

Option 1 includes the following:


?  Inspected Hi/Low range gear set 1.447 or 1.196

?  Hi/Low range hub and slider

?  Main Input Shaft

?  All necessary assembly bearings

?  Side differential cups if required

?  Dual Range housing assembly

?  Complete transmission gasket and seal kit

?  Front hi/low range snout

Total cost comes to $1475 AUD


Option 2 - complete assembled transmission with or without centre differential (viscous
coupling).

A complete dual range transmission assembly in two price ranges, Level 2 and Level 3. Due
to freighting costs neither of these options includes the center diff, but one can be
provided as part of the assembly if required. This will cause some additional shipping
costs.

The level 2 gearbox contains a serviced/reconditioned standard OEM gearset, which is
suited to an individual seeking an OEM compliant replacement gearbox. Comes with 12
months or 25,000 km, whichever comes first, warranty.


?  Inspected and overhauled factory Hi/Low range gear set at 1.447 or 1.196

?  Inspected hubs and sliders

?  Inspected synchronisers

?  Inspected gearbox bearings

?  Hi advanced bead blasted gearbox case

?  Complete serviced fork and rod kit

?  Serviced front differential

?  Set to strict ADS specifications.

Level 2 gearbox is $1950 AUD


LEVEL 3 transmission assembly includes the following:

The level 3 gearbox is the best option for reliability and longevity without any vehicle
modifications. It comes with 24 months or 50,000 kms, whichever comes first, warranty.
This option includes:


?  High/Low range gear set 1.447 or 1.196

?  Revised 1-5 gearset (caroius ratios avaiable)

?  Strongest turbo 3/4 gearset

?  Lever action 5th gear hub

?  New revised hubs and sliders with ball shift

?  New gearbox bearing kit

?  New revised synchronisers

?  New OEM gasket and seal kit

?  Complete serviced fork and rod kit

?  Serviced front differential

?  Hi advanced bead blasted gearbox case

?  Set to strict ADS specifications

Level 3 gearbox is $2450 AUD (minus centre diff assembly)
Optional ISF and shot peen strengthening process $650 AUD


The available transmission ratio's

The dual range transmission comes in two ratios, either may be used depending on the
application.

The 1st and 2nd  gears have 2 variations 3.454/2.062 or 3.54/2.11

The 3rd and 4th gears have 3 variations 1.448/1.088 or 1.36 -0.97  or for the late series
2 only 1.29/0.97

The 5th gear has 4 variations .738 or .781 or .825 or .875

The high low range ratio has 2 variations 1.447 or 1.196

The final drive ratio has 5 variations 3.7 or 3.9 or 4.11 or 4.44


Additional items that may be required when installing dual range conversion kit to either
option 1 or 2 may be purchased from All Drive Subaroo
