    Just bought a Brand NEW 1991 XT6 AWD :) !!! Got money and time! :shock: Want to know some ideas for real world modifying. It has a 2.7 liter engine. AWD and very little rust.

    Here are some of my ideas please feel free to chip in:

    1) Keep the 6cyl (with a light hint of turbo boost stirred not shaken)
    2) Engine rebuild if it aint broke redesign it!!! (cams,valves, ect... A frik'n must!)
    3) Kaaz or some type of locking or adjustable differential, (yup trans rebuild any ideas???)
    4) Interior rip out and reupholster...I work in the furniture business so I can fit a sofa in a van :mrgreen: I know a few people who could pimp my ride.
    5) 15 inch rims, intake, exhaust, suspension, paint, ect...

    My aim is track not dirt. With a slit drift element to it.

    In this car it will emphasis 1) Power! 2) Reliability! 3) Handling! and of course 4) Beauty.

    If you know any one with expert knowledge in this area send them my way.

    I cant do this project alone I need the MNsubaru club to pull it off.

    Thank you.

    for more power, swap in an svx engine, from what im told the 2.7 is nearly identical :D wallah, 240-ish hp as apposed to the 135 you have now ;)

    Legacy wheels fit... so why not put on 16" from a WRX?

    That motor is basically a Loyale or XT 1.8, so lower compression pistons and sodium filled exhaust valves from those engined fit...???

    A EJ2.2 also has 130HP... and has alot more aftermarket support.

    I think I would start with a full assesment of it's mechanical status. Then once you have a feel for what the car needs then look at what upgrades you can do.

    Check all brakes and bleed the system including the clutch.
    Change and inspect rear diff oil, tranny oil, motor oil.
    Check air filter replace if necessary
    inspect spark plugs replace if needed, do a compression test at the same time
    timing belt inspection
    asses any oil leaks
    flush coolant
    check under the car, suspension, links, bushings


    I could keep going but you get my drift. Asses the situation, fix any issues, then form a plan for upgrades from there.

    Wow thank you I shall.

    Biker I am starting the assesment this week the timing belt broke the other day but that is cool i will enjoy the fix up because i have no clue how to time a belt but Fuji gave me an idea.

    AWD...I want the smaller block and want to stick with an unique 6cyl engine, I like the svx, but it is big and heavy. If I owned one it would be my pickup chicks car but my old 2.5rs was enough to do that hehehehe...

    Todd that info I didnt know... thanks! Do you know where I can purchace some after market cams or get them made to turbo specs??? How about thicker copper head gaskets to drop compression good idea or not? If Ill do the piston arm swap to lower compression. I tried some old Japan sites but they are gone. I am sure some one in Aus or Japan is rolin in my future dream ride...

    Well, my last post just got completely deleted.....yarg

    anyway, first off, the SVX had virtually nothing in common with the ER27, except it's an H6. The EG33 (right?) wouldn't even fit in the engine bay, without major modifications, and/or relocation of the radiator.

    next off, join www.ultimatesubaru.net and look for gravity_man, he's got an ER27TT setup in his brat....but I think he's had problems

    also, check out xt6.net, lots of cool stuff there, but I haven't looked there much recently

    The ER27 is an EA82 with 2 cylinders tacked on. the timing beltS oil pump, water pump, front and rear seals, spark plugs, etc. are all the same. it even has dual-port exhaust, (EA82 - 4 cyl, 2 ports. ER27 - 6 cyl, 4 ports)

    This means that EA82 pistons will lower the CR so a turbo can more easily be used, as todd said. but other than that, virtually every mod you do will be either custom, or universal (Megasquirt, delta reground cams).

    The XT6 is a heavy car for it's size, and has typically quite crappy suspension (the air suspension is neat, if it works....). It is quite different than anything else, so there isn't virtually any direct aftermarket support, but I think the front can be modified to fit impreza or legacy suspension. and you could use generic ebay coilovers, and I beleive KYB and monroe are the only sources of aftermarket shocks, but they're not performance stuff.

    Tranny is different than the EJ. forget about Kaaz etc. can't swap in an EJ tranny, input shaft is too long. also forget about regearing.

    please tell me you got the 5-speed

    rear LSD? center diff lock?

    'Real World Modifying'.....for what you want, completely replace/redesign the drivetrain, or get something else ;)

    That's all I can think of for now, get a haynes, and chiltons manual. the timing belts are simple, but make sure you do both tensioners AND the idler with them, you'll be sorry if you dont (or at least I was). and find out why it broke, the oil pump may need a reseal, and/or the water pump might need replaceing (both on my blue GL). leave the covers off when you're done. as long as you're not going muddin, they're just inconvenient.

    good luck, and keep us all posted!!!!!

    Well,

    I think Chux said it all.... Listen to what he said about the belts and tensioners, we both have been there. They are fun cars and I love my XT.

    Take the time to just get everything fixed and then run it like that. It's not a race car, just a cool toy. :)

    I'm going to be doing a motor swap in mine soon and still toying with the TD04 turbo swap.

    Oh well, have a good time with it. :)

    the locking center was available, and it's a limited slip rear.

    I don't know what the auto final ratio is, but it cannot be changed.

    it's 'just' a primitive 4EAT....but then again, I'm incredibly biased against the slushboxes. and I had a '92 loyale AT lose 3rd gear, with zero engine mods.

    I forgot to mention that the NA EA82 pistons are the same as yours, but the turbo EA82 pistons are different. good luck finding any of those around here.

    it also has front ebrake, so drift will be weight transfer and scandinafian flick. or, 200SX calipers are identical except they had rear ebrake, so they will swap right in.....but keep in mind, they're just 200SX calipers....

    I'll probably think of more, and I'll let you know, if you have any questions, feel free to hit me up on aim....


    I don't want to discourage you, but you asked for advice on real world modifying. and I'm just telling you that on stock drivetrain, the XT6 is not worth much. I do REALLY want to see you do it, and I'd love to help, but it's going to have to be very custom. if you want big power and reliability in an XT6.....put an EJ20 turbo drivetrain under it.

    I will be looking at the ebrake soon and engine parts as well. But i will be fixing the timing belt and tensioners myself this month. I will check all seals and gaskets as well and get a new oil pump just to be safe. The more oil the better I say. I do like Amsoil! I am checking on gaskets and piston arms and lengths as well.

    AWD You seem to know a lot about the SVX engine. Does it have 6 independant exhaust ports. Also how close are the engine parts to other versions of Subaru Boxer engines??? I am just wondering about pistons and headers I can adapt for turboing.

    yes it does have 6 independant exhaust ports, and i believe it uses ej 2.2 size pistons.

    The 2.7 does NOT have 6 exhaust ports...
    2 into 1 and 1 by itself.

    The 2.7 timing belt is wider than a 1.8.

    I have a set of service manuals for the XT for sale if you are looking.

    NOT same general size, the EG33 is substantially taller and longer than the ER27. it will not fit in the engine bay without radiator relocation (easy on a wagon or a hatch....not so on the wonder wedge), and hood modification. not to mention the wiring nightmare etc.

    just use an EJ20, it'll simplify your life/project drastically

    yea, as much as I'd like to see a high output ER27, There's way more aftermarket support for an EJ20t, not to mention it's smaller, lighter, and more powerful to begin with.

    I did a bunch of research, and, until a few months ago, was going to build an XT6 to be my AutoX, RallyX, and ice racing toy. and decided the best way was an EJ motor, and RX tranny (but probably won't be able to hold up to more than ~200 crank hp), so I decided since I was going to be doing an engine and tranny swap, I might as well use this rust free loyale in my yard, and have the novelty of having a wagon :twisted:
