Hey guys, I know I may sound like a big idiot but I am fairly new to the legacy scene, and I dont understand the abbreviations "BD", BG etc. I know it signifies a model and/or year, but beyond that I dont have a friggin clue. If I can get clued in I may be able to help more around here lol

BC = 1st gen Legacy sedan (90-94)
BF = 1st gen Legacy wagon (90-94)


BD=95-99 SEDAN, BG=95-99 WAGON

BK also = 95-99 Wagon (that's what I have)

BE = 3rd gen Legacy sedan (2000-04)

Best way to find out is look at your VIN :D

That's how I found out mine is a "BK", whatever that means - I heard somewhere the BKs were made in Indiana, the BGs were made in Japan?

That confirmed it. It's a BJ. What the hell does that mean? Haha...I know what it is. Does this mean my car gets more pleasure than me?

I think your theory on BK made in Indiana is correct, because my scooby has BK on it and i know it was made in good 'ol Lafayette. :)

Thanks for the clarification, I forgot about the BK's, so what are the other oddball letters outside of the BC/BF, BE/BH, and BL/BP? Any differences coming from the American factory?

side note: 89(very rare)-94 = 1st gen, 95-96 2nd Gen, 97-99 3rd Gen, 00-04 4th Gen, 05-?? 5th Gen. There were changes between the 95-96 and the 97-99 legacies, not only in the body.

genki, not enough change to warrant calling the BD/BG/BK's a diff generation. They're still all known as BD/BG/BK's after all. Mine is still a BD, and is a 2nd generation. Its not a new generation until Subaru changes the 2nd letter of the designation.

3rd gen: 00-04
4th gen: 05-??

2deadlegs - Yes, BJ is correct. And how much pleasure your car gets more than you depends on how you treat it. :-D

Slip - GC8 is only designated for the WRX, which we never got. We got the GD/GG WRX, but not the GC/GF WRX. I think the highest we got was the GC6, which, IIRC, is the 2.5RS (98-01).

Those two will only clear up the Impreza codes.

But, you're right about the Legacy codes anywho.

Well, the 95 Outback was just a legacy wagon with extras like power windows, locks, cruiser, A/C, etc, but the 96 Outack was higher, had a differential protector ( I think) and a lot of other off roading type addons. The regular legacys didn't change all that much though....

SubaruGenki
05-11-2005, 09:27 PM
95 GT required Premium gas, 95-96 EJ22 used hydraulic lifters (not sure about ej25's though, anyone know?). 97-99 had different front bumper and 2 piece headlights. maybe we should call the 95-96 2nd gen and 97-99 2nd Gen +, hehehehe.

Reason
05-12-2005, 03:25 AM
Small changes to the body aren't enough to split gens. Using premium gas won't cut it either. Drastic changes in the body I guess would determine the next gen. Correct me if I'm wrong but I NEVER heard of a car make jumping generations because of a 2 piece light vs a 1 piece, or skirts or lifters. You mind as well call the GT a generation of it's own from an L.

05-13-2005, 10:31 AM
hehehehe. shall we? Let's split them up into as many gens as possible, this is a legacy forum after all.... :twisted:

edit: new gen every year? 2006 GT is going to have HID option i beleive....

SECTION 2 - Statistics and Changes
1. 1995 Outback
The 1995 Outback was a normal Legacy with a special trim job and some usually-optional features standard. No more, no less. It had the roof rack, Active Safety Group option (AWD/ABS), and fog lights (the projector type, not the headlamp type of the current model). It also had the grey cladding on the sides and bumpers, but not the aggressive front and rear or the extra clearance with larger wheels. It did have a nifty "OUTBACK" logo on a tire treadmark that I wish they'd kept... that does live on in the Impreza Outback Sport.

2. 1996 Outback
The 1996 Outback was an almost completely new vehicle. Starting with the same raised-roof Legacy chassis, Subaru raised and tuned the suspension for offroad use, used a beefier subframe, put on 15" wheels, added a speed-sensitive steering and optional 2.5l engine, and replaced the projector lamps with those large headlight-type fog lights. Interior changes included a second power outlet in the back, a rubber cargo mat, special floor mats with the Outback logo, and an optional cold-weather package that gave heated mirrors and seats and an engine block heater. NOTE: In the past, I have stated that the 1997 underbody protection panels (skid plates) cannot be used on the '96 models. THIS IS INCORRECT. A new source told me they can, and I was indeed able to install a front and rear plate on mine with no difficulties - it's about a 5 minute job after the car is raised.

3. 1997 Outback
The 1997 Outback starts where the 1996 left off, and makes things better. The 2.5l engine is now standard, and also now available with the manual transmission. It also puts out an extra 10 HP and 7 lb-ft of torque due to solid lifters vs hydraulics and a redesigned air intake system (first solid lifter mainenance is scheduled for 100k miles). Peak torque comes at much higher RPM, though, so there is a tradeoff, but gas mileage increases to 21/27 as well. Also new for 1997 is the Outback Limited, which features a leather interior, weather-band radio and power antenna, new logos and body-colored door handles, exterior "gold trim" package with 5-spoke wheels vs. 6-spoke, interior fake woodgrain trim, and standard cold-weather package. The Limited is also available in several different colors from the normal Outback - black, bright Sydney blue, and bright Rio Red (a Limited in black is at the top of this page - the new logos can be vaguely seen on the front door and grille). 1997 models also have improved side-impact protection, a door-ajar telltale system that actually SAYS which door is ajar, rear-seat headrests, red dials on the instrument needles, and some options that cannot be mated to 1996 models. The exterior has a new logo on the front grille and a hood scoop that actually functions to cool the engine. Finally, the power door locks have been redesigned - there's now a button to lock/unlock everything, and the driver's door lock only works itself. The key only works the driver's lock, and the remote keyless entry functions differently as well - a quick click on UNLOCK unlocks the drivers's door only. HOLD DOWN the unlock button for three seconds, though, and everything unlocks. LOCK still locks all doors. I have no information on whether adding a new keyless module to a 1996 Outback will also give these capabilities. On an odd note, the speedometer now only goes to 120, vice the 140 of 1996. Hmmm...

4. 1998 Outback
A new addition to the Subaru lineup will be the Forester, which shares many similarities to the Legacy Outback, but will be shorter and taller. I haven't decided if I will add the Forester to these pages (same with the Outback Sport). Anyone who's willing to do some writeup on either model, feel free to do so and send it to me. I'll put it in its own section.

Subaru is concentrating on the Forester this year, so there is little change across their other model lines.

The '98 Outback Limited is available with dual power moonroofs as an option, HOWEVER: for whatever reason, the sunroofs are not available on the manual transmission models. The Limited model will also get a better solar-tinted windshield, and darker tinted windows all around except for front doors. The Limited badge is moved from the roof to the middle of the front doors, and the gold stripe along the roofline also drops to follow the fender flares and door line. Also new is a really cool-looking CD/Cassette/AM/FM stereo, with upgraded speakers (8 of them, the new pair mounted high on the D-pillars). The now-standard cold-weather package loses the engine-block heater (still available as an option) and gains wiper de-icers. The wiper de-icers have a switch next to the seat heater switch.

"I just bought a '98 Outback and was curious what the wiper de-icer feature was all about -- I could not see any visible "melting" going on when I turned it on, so I decided to check this out. I had my wife squirt my hand with washer fluid -- not at all warm. I touched the blades -- not warm. Then I spotted a black strip about 2" wide along the base of the windshield -- the place on the windshield where the wipers "park" when they are turned off -- nice and warm!!! This strip heats up similar to a rear-window defroster. So I guess the idea is that if you turn the de-icer on it will melt the wiper blades free from the windshield and also melt away any ice on the blade edge."

Additionally, the OB Limited gets the door courtesy lights, lighted vanity mirrors, and the variable intermittant front wiper like the GT, woodgrain trim around the climate control console, and a new lower body color - Sandstone Metallic! This replaces the Slate Gray Metallic as the Limited's second color. There are also nets behind the front seats for holding maps and junk. These features begin to really differentiate the Limited from the standard Outback.

A weather-band radio is now standard on the regular Outback, which also gets a new fabric pattern, more of a zig-zag instead of straight lines of color. Different 6-spoke wheels replace the original ones as well. On the micro-front, the knob on the end of the radio antenna is now larger and ridged for easier deployment, and the graphics on the guages have been brightened and given a sort-of drop-shadowed look.

Both get a new overhead map-light/storage bin (good for sunglasses and the like), and some small cosmetic changes - the cup-holder, while in the same place, has a different release mechanism and room for a larger beverage container on the driver's side, and the headlamps have been redesigned to use reflectors in front of the bulbs, similar to what Honda has in the Accord (I'm told they're called "multireflector"). Not sure how this affects the bulbs themselves.

Note that the sunglasses holder is not available if you have the moonroofs on the Limited. Also not available with the moonroof are the center roof rails - there's an additional warning against allowing cargo to rest on the roof.

Want to see something odd? Look in the 1998 brochure at the black Outback Limited in front of the nice mansion. Look at the sunroof - looks like only one, with central roof rails behind it. Now check out the red Limited on the next page that showcases the sunroofs. No rails...

Steve Satch also mentioned a listed EPA mileage of 21/26. Can anyone explain the drop from '97? Late note - the drop is only for the auto... 5-speed continues as 21/27.

Optional leather seating surfaces are now perforated to breathe better; IMHO, they also look more expensive that way. Limited standard leather is still non-perforated.

Note that this is UNCHANGED from 1997, though not all incentives and rebates carry so final price may be higher.

5. 1999 Outback
New for 1999: The Outback SEDAN. Subaru calls this an SUS for "Sport/Utility Sedan". Not very original, but certainly capitalizing on a good idea. This is a 1999-model year vehicle, but it's going on sale in February of 1998... The sedan was test-marketed at select New England dealers this past year and looks like a winner. It has all the specs of the Outback wagon (ground clearance, suspension, etc) but with the body of the Legacy sedan. Three pix from the 1998 Detroit Auto Show... notice the slight differences in the grill and fog lights, and the SUS badging on the trunk.






The SUS has been released as of early February (coinciding with the end of the Detroit Auto Show), and is currently available at dealerships everywhere. However, since Subaru isn't considering it an Outback (so far, only Outback Sport, Outback, and Outback Limited make up the differentiated Outback line), I'm not going to devote much space here.

Other changes for the line include making keyless entry standard for both LTD and STD Outbacks, and a few new colors: LTD gets Winestone over Sandstone, and STD gets Quick Silver and Rio Red, both still over grey. The LTD also has a 30th anniversary edition, with auto transmission and the dual moonroofs standard. Prices are holding at the '98 level, even with added content. The DOHC engine remains standard. Both transmissions receive some tuneups for smoother shifting. There's also a new spray system for the front wipers that spreads farther, and the standard keyless gets a *much* nicer remote (looks like the old one about as much as an iMac looks like a 7500...).

*IMPORTANT NOTE* All Legacys manufactured after 10/97 have depowered airbags and re-calibrated front seatbelts. As the new airbags are designed to work with, rather than instead of, the shoulder belts, it is even more important to buckle up. These bags are not retrofittable to the older models.

From _Car and Driver_, Oct. '98: " Changes are coming later in the model year to Subaru's 2.2 liter and 2.5liter four-cylinders, to help boost low-and midranger torque. The engines will share a new head design, which means the 2.5-liter will lose a couple of camshafts. The new heads feature an increased 43-degree valve angle, roller rocker arms , and screw-type value-lash adjusters(replacing the shim-type adjustment). The intake ports on both engines were massaged to increase tumbling of intake air during cylinder filling. Horsepower is unchanged on 2.5-liter, but torque rises by four pound-feet. The 2.2-liter gains five horsepower and four pound-feet of torque. An electronic makeover is coming for Subaru's four-speed automatic. The transmission's hydraulic valves will be replaced with electric solenoids. The new transmission computer uses a new speed sensor on the torque converter for more accurate shifting control. The changes allow a reduction in parts in the tranmission and make it 33mm shorter. "

Also new for '99, but not available to us mortals, is the Outback Special Services Vehicle (SSV). This is a slightly decontented Outback aimed at law enforcement, fire, and rescue services and priced at $19,995 (a few grand below the normal base Outback). Its features include white paint only, no roof rack, no keyless, no radio, no speakers, and no antenna, but with auto transmission and the cold weather package standard. It's a special dealer order, with proof of eligibility required. All other features appear to be there, though - power everything, the 2.5l engine, the same wheels. So if you see an Outback with a lightbar, smile and wave...

6. 2000 Outback

On January 5, 1999, Subaru officially unveiled the new North American '00 Outback Wagon and Sedan. While the rest of the world had been able to purchase the wagon since earlier in 1998, no one had seen the sedan until now. The first two pictures show the Outback wagon, while the third shows the front of the sedan (pictures courtesy Jason Packovich )




The new Outback represents a total redesign underneath the skin while keeping with the Outback philosophy of driving anywhere with the maximum of safety. New features include:

SAFETY:

optional frontseat side airbags (STD on Limited)
integrated rear child seat on as-equipped Outbacks
depowered front airbags
DRLs (go off when p-brake applied)
three-point harness AND headrest for ALL rear passengers (except with optional child seat)
enhanced side-impact safety (dual beams, ring-frame body construction)
seatbelt pretensioners and load limiters
PERFORMANCE:

SOHC 2.5l engine w/ 165hp & 166 lb/ft torque, increased across the range
225/60r16 wheels
gate-type auto shifter on automatic models (see interior picture below)
longer, wider, and lower to enhance stability
new multi-link rear suspension, also increases cargo area between rear seats. Note that overall cargo area has dropped, though.
a 220-HP 3.0l H6 will be released on the Limited version of the Outback in 2001. Initially, it will be automatic-only, but Subaru claims that a manual will follow.
a Limited-Slip rear differential is standard on all Outback LTDs and GTs and part of the Cold-Weather Package on standard Outbacks
COMFORT/CONVENIENCE

4-bulb halogen headlights w/taller glass
all rear suspension components below floor for wider cargo area
6-way power driver seat w/lumbar support (seat cushion adjusts independent of back...)
redesigned cup holders :-) - including one next to the parking brake
greatly reduced NVH
improved gas mileage (4% at speed, due to TC lockup @30 mph vice 38 mph)
vastly increased structural rigidity - 20% torsional, 100% bending resistance
Another gallon added to the gas tank (16.9g US)
New IN-DASH 6-disc cd changer. No cartridges! (option)
Auto-dim rear-view mirror with electronic compass (option)
Color changes - all reds have been dropped in favor of a new Wintergreen metallic green and the return of Winestone. All lower body cladding is Titanium Pearl
New interior color choice of beige or grey in both leather or cloth
Air-filtration system (option)
Rear reading lamps (option)
New extra power outlet doesn't replace ashtray (option)
Roof cargo carrier box, very aerodynamic (option)
Sunroof now available with manual transmission!
Rear window washer is back on TOP of the window, where it belongs, and sports dual nozzles
The mirrors fold again!
Limiteds have in-glass radio antenna
GEEK DETAILS

8-bolt transmission housing, up from 4
2-piece iron/steel flywheel on 5-speed
larger intake and exhaust valves, roller-rocker actuated
50% torque increase at 3250 RPM
Curb weight is up a minimum of 100 lbs per model
Cars have started to appear at dealers, and pricing is in line with the '99's - a couple hundred dollar increase, which easily covers new standard features. Most existing features such as standard keyless entry have been carried over, and the sedan gets a moonroof. The wagon continues with the dual moonroofs, which have been moved slightly to give what looks like a continuous sweep of glass. The foglights have been redesigned to be more powerful (and hopefully more protected).

While this interior is of a pre-production model, the actual insides are nearly identical.




7. 2001 Outback

Subaru goes upscale in a big way with the introduction of two new Outback models, a new engine, a new kind of AWD, and a host of other luxury and performance enhancements.

The 2001 model year sees the return of the 6-cylinder engine to the Subaru lineup. This new powerplant produces 212 HP @ 6600 RPM and 210 lb-ft of torque at 4400 RPM out of just under 3 liters (183 cu. in). It's got direct ignition, eliminating the need for both a distributor AND spark plug wires. It's DOHC, 24-valve, and runs on 87 octane. And it measures only eight TENTHS of an inch longer than the 2.5l 4 cylinder. In addition, the new system features a dual-stage intake and variable-volume muffler, plus chain-driven camshafts (no more breaking belts! chains usually have a MUCH longer life).

This engine is at first only available in the two high-end Outbacks - the new L.L. Bean Edition and the H6-3.0 VDC - and will initially be automatic-only. Both new models include automatic climate control with ambient temperature guage, dual power moonroofs, 8-way power driver's seat, standard side airbags, Momo-designed mahogany and leather steering wheel, heated front seats, rear seat center arm rest, remote keyless entry, and a new design of 16" alloy wheels. Passenger air bages are dual-power, and the front belts have electronic pre-tensioners.

L.L Bean Edition

In addition to the above, the L.L. Bean model also adds the standard AWD, special L.L. Bean insignias inside and out, an auto-dimming rearview mirror w/compass, an air filtration system, standard CD player, LSD rear diff, and the security system.

H6-3.0 VDC Edition

In addition to the very long name (I think Subaru has won the 'most letters on the rear deck lid' contest hands down), the H6-3.0 VDC adds a new kind of AWD - Variable Torque Distribution (more below), Vehicle Dynamics Control (VDC - more below), all-wheel/all-speed tractin control (more below), and a McIntosh audio system (11 speakers and a sub).

The VTD AWD system has a true planetary gear center differential and hydraulic transfer clutch plus a 45/55 standard torque distribution (yes, it's biased towards the rear!). The torque can be varied as conditions warrent.

VDC works with the AWD and TCS to keep you going where you want to go at all times. It takes inputs like steering angle, yaw rate, lateral g-force, and speed of each individual wheel (probably from the ABS sensors). Using that data, the VDC can tell whether the car is going where the driver is steering it. It can then correct for oversteer and understeer by applying split-second brake pressure to the appropriate wheel to bring the car back into line. Automatically. It can also call for more power to the front wheels, and even shut down multiple fuel injectors to reduce power (can this system be turned off? Don't know...).

The TCS applies braking force to a spinning wheel, regardless of what speed the car is travelling at, to move torque to the opposite wheel which hopefully has more traction. It, too, can reduce power by cutting fuel injectors. The upshot of this is that the vehicle only needs one wheel with traction in order to move.

It's important to note that the Outback applies these three systems specifically in the order listed in order to keep control. Only if the AWD isn't enough will traction control come into play, so there should be no excess usage of brake pads...

Geek note: All these systems communicate using a Controller Area Network.

Fuel economy and pricing have not been set, and curb weight is up to over 3700 lbs for both these cars. Coefficient of drag is a nicely low .32, not bad at all for a wagon with roof rack.

Changes to the other Outback models are not yet available.

anyone else think that 155 lb/ft torque @2800 RPM is some serious low end torque for a EJ25? I think its a little off, maybe they meant 4800, cause the EJ22 is 4500.
Thanks for the info, though, that's some pretty heavy detail. Although I disagree about the wheels, my 95 outback has 15 inch alloy wheels, stock.

On the topic of Jargon, my specs in my owner's manual say that I have a EJ22E. Usually you just see EJ22. Is the E anything special, or is it just something unimportant that no one mentions?
