Build My Brat
Posted 25 February 2007 - 12:32 PM
Here's what I have. A nice complete '86 Brat, an EJ20TT (just the motor - no computer, intercooler and such) and possible access to a complete XT turbo, but do not know the year as of yet.
Perhaps my motor selection wasn't ideal, though do not know enough as to what would be, but thought it'd be cool. Am wanting a lift that looks good, but is not excessive and requiring a lot of severe changes to make it work. It'll be a driver and may not see the off-road a lot, but will from time to time (snow, mud). Am wanting a low ratio LSD, I think, a 5 speed D/R transmission and would like some agressive looking off-road tires (details).
So... what would you guys recommend for parts to complete the process and make a mean little machine? Is the XT turbo worth picking up for parts?
I'm not so much looking for the 'how-to', but the 'what would you do if it were yours'. Essentially, parts/products that work well and recommendations. The 'how-to' may come later when I get stuck, but I have some reading of these threads to do before I ever start. I want to get a part list together and try to figure out how much money I'll need to come up with to get the job done and start acquiring.
Thanks for any suggestions and helpful input.

To run the Ej20TT you will need the computer and harness. A D/R probably would not be able to handle the power from the Ej20TT so you might need to use an EJ tranny. Then comes a bit of fabrication and custom work to get the drive lines hooked up.
If you got the XT parts car and are going to do a lift, then use the lift blocks to serve as an adapter and use the XT's crossmember and power steering set up. That's about the extent of XT parts that are usable. The seats are pretty cool, but they are probably messed up from age.
I think that what you are going to do depends on how skilled you are and what kind of tools you have.

dont bother with importing an ej dual range. the low range on em is pathetic at 1.1xx:1. not sure why they even decided to go to that complexity and not put in a decent reduction. best trans bargain is a NA legacy with cable clutch and 4.11 diff gears. they hold up and you can get em for under 300 sometimes. there are tons of em in the yards. you could also go with a forester trans they have 4.44 diff gears but they are a little expensive. you could do a 4eat too if its an offroader. 4eat with 4.44 gears would be pretty sweet.

Couple of questions - remember, it's been awhile, but is the XT turbo an EA81 or 82? Also, what's a 4eat?
Would the 4.44's be too low for normal on-road driving? Sounds like the ticket otherwise.
I see mention of some aftermarket computers. Any preferences? Also am wondering about what to do for an intercooler. Any suggestions as far as going with an air to air or liquid cooled and any good donor vehicles?
Any other motor items to look for like fuel pumps or any other recommended mods?
Any suggested suspension upgrades or handling items?
If it were your project, what items would you put on your wish list? Hopefully I can make some informed decisions and get going on this baby, as I'm sure it's still going to be a long haul. Can't wait! Sorry for all the questions, just am eager to get up to speed.

4EAT= 4 speed Electronicly controled Automatic Transmission
If you go with the auto 4.44's you shouldn't have a problem with on road gearing since they are stock in subie's.
If you can find a 91-94 turbo legacy manual cheap for a donor you could use it's wiring and ecu to better control the turbo motor. and have a pretty strong transmission as well, gear ratios on these are 3.9 and some came with the lsd option.
As far as lift kits go contact Scott In Bellingham, or look in the marketplace vendor area
XT will be an ea82 also
The fuel pump will need to be an external mpfi pump, like would be on that XT you speak of.
As far as suspension and stuff, look into 5 lug swaps on here,

there are a ton of people on there with parts, and knowhow for this kind of build (engine wise), that could come help in person.
as far as the lift is concerned, I've got a couple buddies (one with a brat) who are piecing their lifts together. we could get you into a nice solid setup for pretty cheap.
we should talk in person....and I'll get you set up right. I'm sending you a private message now...

I too just became the proud owner of a 1986 subaru brat. I want to fix it up but i really don't know where to begin. I have never been real knowledgeable when it comes to fixing cars. But I have an idea of what I would like to do and was wondering the best way to go about it. I will be picking the car up tomorrow and will then be able to get an up close and personal look at it. It's a 1986 subaru brat GL. I want to get some more HP to it. Always wanted a vehicle with a turbo, possible to buy a turbo and install it? Would that require a new tranny? Lifting doesn't seem like it'll be that hard but for shocks if i lifted would that require new shocks? I am just bubbling over with questions. I haven't been sleeping well lately because i have been so excited about getting this car. I don't know much about these definitions such as EA81 and EA82. I have come to understand though that i think my car has an EA81. Would love to have a mentor that could break this jargon down into dummy language Thanks so much!
the best advice I can give is to be patient. drive the car a lot and find out what you don't like about it for your own uses. Subaru's can be pretty much anything, and how you build it depends on your personal preference and your uses. don't get too excited and drop a ton of money into a setup that someone else said they liked, it might be a good combination, but it just as easily might not....
that said, don't just slap a turbo on your stock motor. you're not going to see enough benefits without seriously jeapordizing the reliability of the motor...
no, you won't need longer shocks with a lift. but with an ea81 (what your brat is), longer rear shocks can drastically help your travel.
the EJ22 (legacy/impreza 2.2l) is an awesome swap for almost any use. no turbo lag, tons of torque low in the rpm range, extremely reliable, and extremely easy to get your hands on.
