    I will have to check on the weight, thought the manual said 2500, but I'll check it. Yes the XT6 was expensive. (Sticker of 19,500 in '88!!!) It's only 145 horses though so the impreza should be speedier...

  • paisanpaisan Posts: 21,181
    Well carpoint has something screwy on their pages... In 1988 they have 4 cars listed:

    XT coupe
    XT 4wd coupe
    XT6 4wd
    XT6 4wd turbo

    The XT6 4wd is 2795lbs, the XT6 4wd Turbo is 2865lbs.

    Now in '88 there were:
    XT Fwd
    XT Turbo (1.8l turbo) Fwd
    XT Turbo 4wd

    XT6 Fwd
    XT6 4wd

    The XT6 never came in a turbo model.

    I shall research some more and find out my results.

    19mm is a good place to start. I am running a Whiteline18-20-22 bar set to 20mm on an otherwise stock OB, and am very happy with it. It did very well at the track. IF I had a GT with lower sidewalls, better COG, stiffer suspension, etc., I would consider bumping it to the 22mm setting, but I don't so I won't. 20mm is just about perfect for what the rest of the OB setup can handle, given it came with 18mm stock. Start with the 19"; it won't be a radical change, but you'll feel it. After you take a driving course or two you may want to adjust up...just make sure your significant other knows, or there could be a nasty surprise on a slick exit ramp one day!
  • ateixeiraateixeira Posts: 72,587
    You mean 19mm, not 19". You don't even have enough clearance for a 19" bar! :o)

    XT6 4wd Turbo? Best kept secret? ;)

  • paisanpaisan Posts: 21,181
    Maybe I should do that, slap a TT on the XT6, then it would really have some zig! My mechanic and I are actually trying to find some rear performance shocks for it right now for when we do the air-suspension conversion, we are not having much luck :(

  • ateixeiraateixeira Posts: 72,587
    I guess that's the catch with a fairly rare car. Few are familiar with it, plus aftermarket parts are hard to come by.


  • ramonramon Posts: 825
    I didn't know the XT6 has all those luxo crap too. heheheh.... I guess it ain't that light after all huh?
  • paisanpaisan Posts: 21,181
    It's a very mis-understood car! Even @ 2800lbs, an H6 under the hood, and a slush box, it's pretty speedy. I gave the Impreza guys who had sticks, rear bars and upgraded tires a run for their money @ auto-x. After I complete the suspension conversion, and put Juice's 15" rims with some good tires on and a K&N filter it should be in much better shape! Did I mention I love that car? I really need to take a pick of the front or back with my AWD 4ME NY plates on it and send it into Drive mag.

  • Thanks for all the input.

    Lucien - I think the rear bar on my GT is either 15 or 16mm. Is the OB 19mm?

  • lucien2lucien2 Posts: 2,984
    Stock OB is 18mm. I guess 'cause of the height.
  • ateixeiraateixeira Posts: 72,587
    Really? That surprises me. Not bad for OE.


    PS You ought to play with the settings in a snowy parking lot, to see at what point oversteer appears
  • I am interested in knowing which companies are producing anti-roll bars, strut tower braces, and other suspension and go-fast goodies for Subarus (in particular the Legacy GT). I already know quite a few, including STi of course, but am always interested who else is out there.

    You can post names (and websites if you have 'em), or email to me directly at


  • Greg -

    Cobb Tuning just started carrying the Whiteline adjustable rear sway bar for 00+ Legacys:

  • ramonramon Posts: 825
    We have a spy here guys. Don't tell 'em. He'll tell Subaru to not honour the warranty on out sway bars. ;-)

    I notive you're from Subu of Canada. Mississauga branch?
    Anyways companies that makes 'em : FHI, JC Sport, MRT, Cusco, is whiteline adjustables from MRT? anyhow those are the ones I know...
    errr.... I've been doing my routine oil change at a Subaru dealership sir yes sir!!! :D
  • ateixeiraateixeira Posts: 72,587
    Here is the bible:

    Look under parts & service, then americas. There are dozens of vendors.

    SPT sells sway bars for the Impreza/Forester, but I'm not sure about the GT.

  • lucien2lucien2 Posts: 2,984
    Oh, we got oversteer, but only in a turn with throttle lift and/or brake input. The car feels very controlled and communicative right now, very stable, with less oversteer. I think going to 22mm without additional upgrades elsewhere will make the car too tail happy. It really feels very good right now.

    Sway bar suppliers:

    to name a few.

    One thing I've seen at Cobb's site but have heard no feedback on are the Borla headers. Anybody heard results on this mod? What kind of power gains?

  • locke2clocke2c Posts: 5,038
    The Borla headers definitely boost torque in the mid rpm ranges and taper off a bit at high rpm (probably because of the design).

    However, there are several folks on the iclub that have gotten check engine lights related to the first oxygen sensor after installing the new Borla header.

    I can't recall anyone getting this with the original design, and honestly I haven't followed the threads too closely because I'm not going to buy one.

  • dzartmandzartman Posts: 112
    Thanks, Colin. Just curious...since you do Auto-X, why aren't you in the market for the headers, if you don't mind me asking? Not enough gain for the buck?

  • I found Trey Cobb to be very generous and straight forward with information. If you haven't done so you might email him regarding his experiences with the new Borla header.

  • locke2clocke2c Posts: 5,038
    I'll second Bit's appraisal of Trey...

    Dave-- that's exactly the problem, not enough gain for the buck FOR ME. I presume you've seen the pictures of the new Borla header, and have seen the factory setup up close and evaluated them. I could probably find pictures of both if necessary, but for now I'm just going to describe the problem.

    Neither the original nor the new Borla header has equal length tubes. This is important because it keeps exhaust pulses evenly spaced, allowing better flow and low turbulence. (That's an overly simple explanation but oh well.)

    The header is designed to mate to the stock catalysts, which means it terminates facing directly towards the right side of the car, and then the catalysts are curved to not-so-gently bend towards the rear of the car.

    To me this is an unacceptable performance loss, and if I'm going to bother to replace the stock header, I'm going to get one that does it right even if I have to replace my defective stock catalysts. (Federal law says you can't replace a working one, therefore mine are failing.) MRT in Australia sells an equal length header that also utilizes a single straight high-flow catalyst, and thanks to the strong US dollar / weak AUD, I can get it cheap.

    I wouldn't dare attempt this in California, it would surely fail a competent visual inspection. It's perfectly fine in Kansas though.

    Anyway, the fact is that the Borla header does offer an improvement over the stock header and it probably does the best it can while connecting to the stock catalysts. If those things are important to you, which they would be for most normal people, then I'd say the Borla header is a good product.

  • Dave, AWESOME compilation. Thanks for sharing it.

  • ramonramon Posts: 825
    Ever thought of compiling this entire list to a webpage and then post the link to that page? Great job however for collecting all the infos.
    Check out :

    I thinkit has EVERYTHING Subaru related pretty much. It's my Subaru directory really.
  • I did a quick post of Dave's links to my web site. Dave - if you object please let me know an I will pull it. Thanks for the great list regardless.

    Dave's Links:

  • Well, I finally got my first add-ons for my Subaru Forester: the front air deflector and the rear window dust deflector. The front air deflector is the one that was on backorder while they came in on a slow boat from Australia.

    Anyhow, the front one goes on pretty easily, using a couple of clips and some bolt-on clips that come out from under the hood. No drilling required. The rear dust deflector is a different story. It requires drilling, and also requires being able to shove some inserts into the rear hatch with a special tool. You're also supposed to slather the holes with rust inhibiter. I'm going to let a dealership do the install, I'm not up to the hassle.

    Question: How much should a dealer charge me to install this thing? Has anybody else had one installed on their Subaru Forester? How much did the dealer charge? I know the install would take me several hours, but most of that would be because I've never done it before and would spend half my time rummaging through the toolbox trying to find the right sized drill bits etc. as well as running out to the local AutoShack for some rust inhibiter. I'd suppose that somebody who's done it before could probably do the install in less than an hour...

  • locke2clocke2c Posts: 5,038
    Wow, I killed that header discussion quite nicely.


  • ateixeiraateixeira Posts: 72,587
    Eric - I'd figure about 1 to 1.5 hours of labor. Your dealer's rates should be available, maybe even posted.

    Headers would be a pain to install. You're talking about working in a tight spot with likely rusty components that are rigid and may be hard to line up. All that work and $400 or more for 3 or so horses?

    I'd try the pulley first. Then a cat-back and/or intake. Just seems more cost effective.
