So to sum up: EA81 hatchback - must be rust-free (probably from west coast) and solid running (at least well enough to get back to NY lol). EJ22t engine with TD0516G turbo, 550cc yellowtops and a 550 Robtune ecu - should be good for somewhere btw 250-300bhp. Fuel System - hoping to utilize a deatschwerks300 in tank pump with stock sender if it will fit in the hole. If this does not prove to be feasible, then the stock sender and in-tank pump will be used, using the in-tank pump as a lift pump for a Deatschwerks 350iL or Bosch 044 pump plumbed in-line outside of tank with filter. This is very similar to a Volvo 240 setup which I am very familiar with. Front suspension - Impreza knuckles/struts/brakes. 5MT from 1996 legacy with XT6/RX center as per the "poor man's dccd" thread on legacybbs. rear end - legacy rear subrame modded to fit EA81, running a 3.9 final drive R160 also from legacy. Legacy/impreza brakes and struts out back also. Cost - anywhere from $2k-$3.5k in parts plus the $$ for the car plus many hours of time So that's where I'm at so far. This should yield a roughly 225-250awhp car that weighs around 2300lbs with a full-time AWD, DCCD setup. Should be amazing.

Yeah, whatever happened to this thing? Cool build.

Leaving this here as I wrestle with going with modding the legacy subframe or go the XT6 parts route in the rear. The ideas presented in that thread were similar to my own conception of how to go about installing the legacy subframe (I definitely would not go as gung-ho as this guy did with the shock tower treatments) I was planning on a tower to tower brace, just not as crazy as he did. Thanks to 86Bratman for finding this thread. http://www.rx7club.com/old-school-other-rotary-63/little-project-i-like-call-gloria-gl-re-ea-922472/

Finally found some information on front cross-member width differences, I had been trying to find this today: Measurements are as follows; Hole spacing, front to rear: EA-81 = 5-9/16" EA-82 = 5-9/16" ER-27 = 6-3/8" Legacy EJ18 = 6" Hole spacing, side - side: EA-81 Front = 31-1/4", Rear = 29-11/16" EA-82 Front = 32-7/8", Rear = 31-15/16" ER-27 Front = 33-1/16", Rear = 31-7/8" EJ-18 Front = 33-13/26" Rear = 32".

aaaand of course, that is NLA, as has been mentioned all over this forum. I did wonder why I was seeing it as it was Subaruparts.com that I found that part # at. The site is a little confusing in that it offers up 3 sets of rear end diagrams for the XT6 and 2 of them say "all exc. 4wd" but the 3rd does not and that one is the one I pulled that # from.

If I could import it into excel and fix it, I would but I guess your post will be sufficient correction for anyone who dares tread the choppy waters of this thread On a side note, when I was thinking of modding the Legacy subframe into the hatch, I had a complete brain fart and forgot to consider wheretf the gas tank would go. This car would be driven primarily on the street and so I need the interior to be functional. This rules out a fuel cell of some sort. Whew, glad that popped into my head now instead of later.

Found a very nice table of spring rates, upper and lower spring diameters for both front and rear for all ea82, legacy and impreza cars to '04 courtesy of NumbChux. Leaving it here.

Did some digging online, found new wheel hubs from Subaru available as mentioned in the updated list. A curious thing that I'm currently pursuing lists this particular hub as fitting others as well: "This product fits 128 vehicle variants. Subaru: 3 models, 128 variants between 1985 and 1991." I do not know yet how accurate this is. I will edit this post with new info (good or bad) when/if I get to the end of this particular trail. EDIT: Pretty sure that list is a load of crap, look at all the models this hub supposedly fits HUB-REAR AXLE This genuine part fits your 1991 Subaru XT 6 Your Price $187.84 Part Number: 23610GA041 This product fits 128 vehicle variants.

lol @ the phone issues, I know how that is. Once again, you have given me more food for thought and once again, your ideas are spot on. My thoughts with the R180 were in the direction of welding some standoffs back there with some reinforcement plates and directly bolting a legacy rear subframe to them utilizing WRX or STi stuff for the rubber (it's stiffer) for both the subframe and the diff - it would have been pretty much a beefed up legacy under there. At the time you posted this last night, I had been doing a lot of reading on the front and what to do there and in my head, I was almost where you ended up. One detail I could not find on Google for the front was how much wider the resulting track would be and how much wheel poke would result. In the rear, had I gone that subframe route, I would have gained 1/2" of track on either side. I freely admit that that was pure speculation based on data I found online and not actual measurements since I have neither an ea81 car nor a legacy to measure, but the data I found suggests that an ea81 car has a 58" width for rear track whereas the legacy is supposed to be at 59". This is why that idea appealed to me, combined with the fact that a lot of legacies came with 3.90 diffs (LSD or otherwise) and the ability to bolt an R180 in sealed the deal in my head. However, as long as the CVs and XT hardware could hold up to the torque of the 22t, that would certainly be the easier (and more likely to happen) route to take. EDIT: I have decided to go the XT6 route, it's just simpler, even if I break stuff

Thank you, awesome and cheap is my personal holy grail here lol

LegSportWag's Legacy running a 550 tune w/ the Rx/XT6 center diff mod...leaving it here for some inspiration! http://vid14.photobucket.com/albums/a311/Gratefuldead538/10649397_840448102667115_587298792_n_zps62a24161.mp4 Would love to see a 60 foot timeslip on that car - bet it's awesome.

Just thinking out loud here: wonder if I could use an R180 as it is factory LSD and swap ring gears...that would be convenient. I would be ok with using the larger rear hubs and all that that entails. One happy effect of all that work would be the fact that combined with the WRX 5 lug conversion up front, I would be at 5X100 at all 4 wheels - opens up a lot of possibilities for wheels and brakes.

I think the cheap answer for me in this case is to just procure a 3.90 diff (LSD or not) and swap the ring gear to any ratio LSD. This way, I figure I can get the LSD but achieve the correct final drive without dealing with backlash and preload by leaving the pinion alone. I realize I will probably have to do some grinding inside the case to do this, but no big deal.

Yes, that was what got my interest initially when I found that thread was the cost of the later, admittedly more capable transmissions versus this seemingly simple and cheap mod. I'm really hoping to hear that it's still together with no problems. I did note one possible downside to this mod: one is stuck with a 3.90 final drive. In my case, that was actually the ratio I wanted but I can see that being a turnoff for others tempted to try this. I am now looking into which cars came with LSD 3.90 rear diffs. There are not many.

Message I sent to LegSportWag: Hello, I was reading your Poor Man's DCCD thread and I have a couple of questions I hope you can answer for me. I'm currently in the process of getting ready to collect parts to do an ej22t swap w/ aTD0516G, 550 robtune and STi yellowtops into an ea81 hatch and I was wondering: How well has this mod held up for you? Have you had to replace any components yet? How well does this driveline function on a daily-driver basis? How much power are you currently routing through this "frankenbox"? Your response(s) would be extremely helpful to me in deciding which direction to take regarding my transmission choice. Thanks for your time! -- Dan We'll see if he responds, I hope so!

Quotes from Poor Man's DCCD thread on Legacycentral bbs courtesy of LegSportWag: "I was looking at picking up an Rx. The beauty of this "franken-box" is if I would have put it in an Rx, gl10, or xt it would have bolted in without custom drive line, shifter linkage or trans mount.. Basically this would allow you to bolt an ej motor in with out the normal ej to ea adapter plate". "Same situation lets people wanting to do ej swaps in eacars run a normal ej clutch. Ea clutches are too small for the power an ej can produce. Especially turbo ej motors" " I thought the viscous diffs transferred a certain amount of torque per 400 rpm, which to me sounds like it should transfer more torque as RPM differential increases. But what I've experienced seems to be that it work fine under low RPM differential, and tends to just give up if you really get on it. I dunno, maybe my center diff is just old and tired,although the car it came from was in awesome shape without a ton of miles." (LegSportWag's reply) That's exactly how viscous centers are.. They get worse with time and usually after about 10 hard launches they are pretty well shot.. I'm loving this diff locker. Lights all 4 up consistently." I'm going to PM him and ask how it's held up, he's running a robtune 550 which is what I need to get. I do not know what turbo EJ he's running yet, but I will find out. Not arguing with Bratman in any way, shape or form - just trying to learn!

Hmm..I was under the impression that that mod would allow for an EJ clutch to be used, as you are, in essence, installing an EJ transmission. However I do need to keep the power levels in mind...I will revisit that thread and maybe ask the fellow a question or 2 about it. Another reason it was attractive was cost as both of those transmissions together cost far less than an equivalent WRX 5MT (my other choice) and would only require time on my end. I do need to look into it more as replacing that setup over and over again would not be very exciting to say the least!

Decided to also add prices to the build list. These prices are either what I can get locally or what I have found online. Subject to change, of course, but useful for both myself and others who may come across this thread with similar aspirations. (Incomplete and in progress as I research) EA81 Hatch - $$free all the way up to $4k (probably looking at in the $1200-$2200 range for a solid runner with good body from out west) EJ22t engine - $350 Legacy 3.90 final drive 5MT AWD transmission and AWD 5MT from RX or XT6 as per this thread:http://bbs.legacycentral.org/viewtopic.php?f=7&t=53943&p=427585 (Looks very simple to do!) Legacy 3.90 5MT - Can be had for as little as $200+p/u. RX/XT6 5MT for "poor man's DCCD" mod - Can be had for as little as $150(!) plus p/u. TD0516G Turbo - New = as little as $205 on fleabay up to $1000 from Precision. Used=?? STi yellow top 525cc injectors - New = $100x4 Used = I found a set of 4 on CL for $100. 550 rob tune ej20g ecu plus 4to2 ignition converter: $350 (includes shipping, also assumes you are shipping ECU. $455 if he provides ecu for you.) '91-'94 Legacy Turbo harness - varied between $65-$150 for complete engine side and $50 for dash side.

agh, goddammit lol. That was info that up till now I could not find, thanks again Bratman! Edited project summary to reflect this.

As this project stands now: EA81 Hatch EJ22t engine Legacy 3.90 final drive 5MT AWD transmission and AWD 5MT from RX or XT6 as per this thread: http://bbs.legacycentral.org/viewtopic.php?f=7&t=53943 (Looks very simple to do!) TD0516G Turbo STi yellow top 525cc injectors rob tune ej20g ecu OBDII engine and dash (for trouble codes) harness

Thank you for that thread, it would appear that all that is needed is to procure an OBDII engine harness (for the plugs and scanner ports), matching era intake and wire it up. It would seem that the task is essentially the same whether it's OBDI or not.

Browsing on car-part.com has revealed multiple AWD 5MT from $250 to $1000. I ran a search for 1996 Legacy (non-outback) 5MT as I believe, according to various sources, that these are 3.90 final drive transmissions, which I feel is perfect. Thoughts? There are also XT6 5MTs available there as well. Is the newer Legacy 5MT more robust or are they the same? I am uncertain since I am unsure if the 5mt behind the EG27 is EA based or was ahead of its' time and was the basis for the later EJ transmissions?

So, sensors did not change between OBDI and OBDII, just ecus,wiring and manifolds?...interesting if true, that's very helpful!
