    04 -07 Forester XT vs WRX Wagon

    Looking at the stats the 04-07 XT seems to have the same year wrx beat. 2.5L engine from the sti, stronger transmission, and the struts the wrx wagon rally cars want. The only downside I can find is the steering ratio is a little slower.

    I am missing something? Why is it all wrx at the rallys?

    Probably for homologation purposes. The FXT has a less rigid chassis and poorer aerodynamics. That being said, I would buy a 2004 Forester XT if I were to do it over again (though the 4.44 F/D makes for an annoying highway commute )

    Keep in mind that a true WRC is about as far removed from even the top-trim STi as a regular road car is to Touring Car racing.

    Make sure to drive the cars in question, as numbers don't always tell the tale. I drove a friend's FXT around during some camping escapades...great engine, but it handled like what it was, a small SUV.

    What is it that makes 4.44 annoying on the highway?

    I know the forester is built on the imprezza chassis, does it have less reinforcement that makes it less stiff?

    I can see it handling more like an suv with the longer struts, but i sure have seen enough video of them sitting flat in the corners!

    My original plan was to pick up a 2.oL rex wagon and put in forester struts. I live in backcountry BC but love a car that feels tight on the roads, too. Kind of working at cross purposes ( :

    Less stiff doesn't sound good to me though! Seems to me like a rex w/forester struts should feel pretty similar to the actual forester.

    You'll be at about 3000 RPMS at 60 mph in top gear and pushing 4000 RPMs at highway speeds. The rex with 3.9 F/D is at about 2300 RPMS at 60 mph in said gear.

    Woah! Are you sure about that? What does that make your revs at 100mph?!? Or 120 for that matter? If this is right I don't think it will work for me, what kind of project would it be to swap for a different F/D?

    why? I mean, for fuel economy I get it... but why? The shorter gear ratios make the FXT faster in the quarter mile to the WRX despite having less overall hp and more weight. If you really want to change the F/D that would require transmission and (maybe) rear diff swap. But again, why?

    It has the same short block from the EJ257, but it's not an EJ257.

    You forgot to mention that it's lighter than an Impreza too...

    I do love Forester STI builds though!

    It's not. The 2.5L WRX, yes... but not the 2.0L. The 2004 FXT was billed at 3190 pounds, while 2.0L WRX wagon weighs in at 3160 pounds. The 2.0L Sedan is 3080 pounds.

    After 2004, the FXT just got chunkier

    Thanks. Plus wasn't it just the 04-05 FXT that had the EJ257 shortbock?

    I do a fair bit of highway, as in I'm always either on a highway or a dirt road! 3000 @ 60 just sounds strung out! I remember having a corolla back in the day (sweet sr5 rwd hatch) that reved at 4000 cruising at 80 and wishing there was a couple more gears! Ya for MPG but also just listening to a car with lots of power left and no gear for it.

    +Around these parts it's not uncommon to cruise at 100...uh... hypothetically.

    That's where the power is! These motors don't make peak power until approx. 6000 RPM

    I think you are right. The 2006+ received the EJ255 shortblock IIRC. Not that there is too much difference between the two, but they are stamped differently. The heads, though, I have no idea. 2004 and 2005 have 8.2:1 CR, while the USDM WRX EJ255 has 8.5:1 (right?). STi has 8.2:1 but I think this has to do with the bucket size and piston shape.

    EDIT:
    2006+ FXT has 8.5:1 CR, so this seems to (at the very least) not disprove our theory...

    Yeah, the only difference between the EJ255 and EJ257 short blocks are the pistons. Of course, there is more to an engine then the short block and the EJ257 is a sweet deal.

    Correct me if I'm wrong, but the 4.44 rear in the AWD system isn't a direct correlation to say... a '70 Nova with a 4.44 12bolt posi rear...

    Not trying to hijack but what would the F/D do to fuel mileage if you have lets say an 2 -3 hour highway commute every day? What does that look like for top end power. I would assume the FXT would would run out of gears before the WRX wagon stopped pulling.

    Yeah, you are correct. At least the way I understand it, the speed reduction from the motor (input) to the wheels (output) depends on all the following items:
    1. Gear ratios
    2. Final drive on the output shaft
    3. Differential multipliers
    4. Size of the wheels (in terms of vehicle velocity)

    For example, the 2006+ USDM WRX actually has a 3.7:1 final drive ratio on the output shaft of the tranny, but the center diff has a 1.1 multiplier so effectively the speed to the front and rear diffs are the same as the 2002-2005 WRX with 3.9:1 F/D and 1.0 diff multiplier.
