Cruise control is disabled whenever the check engine light is on, in those cars. Pretty long and well-documented diagnostic process to the P0420.

Should be largely the same. Use STi Head gaskets, just like the USDM 2.5s.

Aisin is the way to go if you want a "kit". I use Mitsuboshi belts, NSK or Koyo bearings, and an Aisin tensioner. Requires more homework to find all the right part numbers (I usually look up OEM # by VIN, and cross reference from there), and sometimes ordering from multiple sources (I've been using CarID for the last few sets, but I think I've gotten the tensioner from RockAuto). Don't think I've bought a water pump in 10 years or more...

I've heard of people machining/redrilling the stock hubs to 4x100. That's probably your best bet, if that's the size you want. It gets difficult as it begins to clash with the bosses for the rotor mounting bolts. You're currently running a 7" wide wheel with 4.5" of backspacing (meaning 1" of negative offset!), yea, that's not going to fit well. A stock Toyota or Nissan 6" wide wheel will fit much better. It is certainly possible to have new hubs made, but my understanding is cutting the splines is extremely expensive. Someone had a run of 5 lug rear hubs made not too long ago. They were manufactured overseas in large-ish quantities, and they were still spendy. I suspect having 2 pairs made (they are different front and rear) will be many many thousands of dollars.

I'm not sure replacing the part would have a different effect. It's my understanding that they are very sensitive. My mom has said many times that she can only put in about a 1/2 quart when the light comes on before it's at the "Full" mark. She keeps a paper funnel tucked in next to the battery....

Off the top of my head, 4-cyl AT Outback and (I think) GT are 4.444 axle ratios. H6 Outback is 4.111. So you might have to swap rear diffs, as well. www.car-part.com is a very useful tool for finding used parts.

I've seen many broken, especially on crashed cars, but not always. Get a new one. I bought a Subaru one for our Outback, so it couldn't have been too expensive. And they are available aftermarket.

Yes, that car has an oil level light, and an oil pressure light. If the oil pressure light comes on on the freeway, the engine is done. If it flickers a little bit at hot idle, you might be able to save it, but at rpm and load....no. We discovered with my mom's 12 Impreza that the level light comes on pretty early, sometimes the level doesn't even read to the low mark on the dip stick, and only needs about a half a quart to read "full". Hers is a bit of an oil burner, so she's gotten used to carrying oil and a funnel.

OEM water pumps very rarely fail. Not a chance I would replace it at 120k miles. I buy a Mitsuboshi belt, NSK idlers and Aisin tensioner separately. Anything beyond that would be as-needed.

Yep, not uncommon problem. Nut too loose, and/or incorrect washer placement underneath it. Strips the splines in the hub out.

I just did some quick math (what can I say, slow afternoon at work...). My mom's 2012 Impreza uses a quart of oil about every 750 miles. When I worked at the dealership, we had many customers reporting a loss of 3-5mpg after receiving a new shortblock (with tighter rings). Over 750 miles, with fuel costing $3/gallon, a drop from 35mpg to 32mpg is about $6. Depending on the oil you're using, you could easily come out ahead. If you're getting 4k miles to a quart, that difference jumps to $32.13. If you can find a quart of oil for $32, you're going something wrong. So yea, it's cheaper to risk a little extra wear on your cat than replace your engine.

They call for 0W20. That's right in the heart of the oil consumption class action lawsuit that was filed against Subaru. Subaru extended the warranty to 100k in response. There are 2 oil lights. A low oil level light, and a low oil pressure light (the older cars only had pressure, and interestingly the first few years of FB engined Foresters, most Forester owners just drove them until they blew up, whereas Impreza and Leg/OBK owners got the warning light). The level light comes on kind of prematurely, as the engine is usually less than a quart low. But this prevents catastrophic damage. My mom bought her 2012 Impreza with about 20k miles on it, it's over 200k, now. It has a salvage title, so was not eligible for a free engine, so she keeps a quart of oil in the trunk, and a funnel tucked in next to the battery. I just found out this week that she's down to ~750 miles per quart, so I advised her to switch to synthetic 5W30. She has seen a P0420 a couple times, so the cat is probably not happy with the hundred + quarts of oil that has gone through it,

I was trying really hard. It's a shame I wasn't able to follow it through, but it was just too rusty. Nothing wrong with sleeves, IF the spring rate and damping match well. I've been running a pair of those same sleeves, with softer springs, in the rear of my Celicas for nearly 10 years (across 2 different cars). They ride excellently.

It has to be leaking somewhere.

Those eibach springs and GR2s are still on my XT6 (in pretty sorry condition). They ride taller than stock. I believe that Japanese one in that speedhunters article is 4WD. It's a turbo with a 4EAT, and I see the height control button, meaning it had factory air suspension. Pretty unlikely to have all that and FWD. Here's the setup I had on my Loyale. NB Miata shocks with coilover sleeve springs. This is Miata front shocks, the rears are about 4" shorter. Or, if you don't care about ride quality. Grab some ebay coilover sleeves in a ludicrous spring rate, slip them over the stock shocks with no bump stop, and look baller (this was awful to drive on the street. I did an AutoX on a nice smooth runway once, it did well with that): http://i26.photobucket.com/albums/c108/Numbchux/PICT3068.jpg

Yep, you'll need a turbo crossmember and sway bar to clear the up-pipe (not the oil pan). Steering rack is the same. Turbo legacy is a direct swap, of course. The GG one can be used, but the tabs where the control arms meet the crossmember are a bit wider, so you'll have to shim them for the older gen arms. Not a big deal. If your Legacy does not have an LSD (I think only the Turbo's did), you should be able to just use those axles. Otherwise you can use the GG rear axles (note, the GD [sedan] axles are too long for the narrower Legacy chassis), the only thing to watch for there, is ABS tone wheel. But I think on the Legacy (if it even has ABS) that would be bolted to the hub, not pressed onto the outer CV cup.

Yep, I would assume 2.2 engine/intake manifold and 2.5 wiring, electronics (including the coil pack). I did a 94 2.2 into a 96 Outback years ago, and that's how I did it. Worked great.

The Japanese economy was booming in the '80s, and crashed in the early-'90s, and that really shows in the cars. The 2nd gens were just reheated 1st gens, as they did not have any money for real devolopment. IMHO, they feel like tin cans, and the interior feels very cheap and poorly made (little things like the gauge clusters being largely front-lit, instead of back lit). They were forced to spend some money on the ECU and fuel injection system to comply with OBDII for 1996, which makes diagnosing those engines a lot easier. But I still think I'd prefer 1st gen to 2nd. That said, I MASSIVELY prefer a 3rd gen Legacy (specifically, the Outback based on it. I have 6 of them, 7 including the Baja). I have an '01 Forester (last year of the late '90s generation) with just under 100k miles on it and in phenomenal mechanical condition, it will be sold soon. Getting out of a '99 Outback and into a '00 feels like getting out of a Corolla and into a Lexus LS. But the biggest thing. These things are all in the neighborhood of 25 years old. How it was stored/used/cared for will have about 50x more affect on how reliable it will be going forward, than what it was like new, or any generalization any of us can make. $5k is a decent budget, even in this crazy market. Look for a nice clean example that's been loved and maintained. Inspect it thoroughly (or have it inspected), and you'll have years of use to come.

I've never seen anyone reflash the obdi EJ ECUs, there have been a few things available for the SVX, but I think those are all off the shelf tunes, and not tuneable. You would have to remove (desolder, most likely, although you could probably install a socket to make it easier to do again in the future) the EEPROM chip from the ECU board and put it into a reader/burner. Download the raw code. Decode it. Recode it. Burn the new code to the chip. and then reinstall it. Every time you want to make a change. Yuck. With the cost of a Speeduino or Megasquirt these days (and even a speedy is likely considerably more powerful than a 30 year old factory ECU), I don't think any of that makes any sense.

Yep, 85-87 EA82s had amber lighting, and '87.5+ had green. Since the EA81 continued in the Brat and 3-door hatch through '87 here in the US (and a lot later in other markets), it's possible the changeover was at the same time in EA81s, and yours doesn't have an original clock (notorious for cracking solder joints, so it's not uncommon to not have the original). It's been a long time since I had a battery in my Brat ('84), but I thought it was amber....

Check the code on the transmission by the starter. You can usually google that code and find a listing that will tell you the gear ratio. I would have guessed a 5MT 4WD DR to be a 3.9, but 3.7 is certainly possible.

Yep, I'm sure that's exactly what GD is recommending, and I would, as well. The OEM service intervals don't mention changing CVT fluid, but there have been more than a few failures on these. My mom's 2012 Impreza is over 200k miles on the original CVT. She drives it like a little old lady, but also we've change CVT and diff fluids a few times. The engine treatment, fuel system cleaner, induction cleaning, etc. is unnecessary expense, and the companies that sell those products, likely have some sort of cash kickback to the people at the shop for selling it.

I hate using hardware store bolts. At the very least, they will have the wrong size head. The dealership here in town stocks pinch bolts. I'd just get it from them. Also, price out the ball joint from them. I've had HORRIBLE experiences with aftermarket ball joints, and the OEM ones aren't expensive.

I saw the screen name, and assumed someone had bumped an ancient thread, lol. Still playing with '6s, huh?

I believe the VIN should be stamped on the side of the case (or, many places on the car). Bring that to your dealership, or online parts source (I like www.partsouq.com) and look them up. Once you get it put back together, change the gear oil in there occasionally. That s*** looks nasty! Over 200k on my mom's 2012 Impreza. Original engine and transmission. We'll probably do it's 4th CVT and Gear Oil change here pretty soon. It does rev up higher than I'd like, but it's a 2.0, it has no torque.
