96 legacy wagon
ej20 swapped, white

Default 96 legacy to 02 wrx...

So ill start off by saying what I've got. Currently I have 96 legacy brighton wagon 5spd 2.2l. I bought a ej20 out of a wrx a few weeks back. I collected an 02 ecu, 02 complete wiring harness, wrx turbo crossmember, catless up-pipe, catless down-pipe, full 3" exhaust, an intake, oil pressure/boost/air fuel gauges....

I plan on running the 96 legacy drivetrain, for now. I'm just going to upgrade the clutch. I don't plan on banging gears or hard launches so It should hold up for a while, its also dirt cheap to replace unlike the wrx drivetrains haha.

Now my questions...

My motor came with pretty much everything, but I did not get the stock boost solenoid. Should I try to find a stock one, go with the GM boost solenoid, or go manual boost controller?

It also seems that I am missing some lines around the motor(IE vacuum lines and maybe some others) are there any good books that have diagrams of what goes where? Relating to the question is there any manuals or reading material specifically that people found to be a great source during their own swap?

Finally, does anyone have any words of wisdom, any helpful hints? Anything specifically I should be looking for?

I plan on pulling my motor this weekend or up coming week...so anything you can't tell me would be great.

Also I'm doing the wiring myself, so my game plan is to label the entire legacy harness as I pull it out to lesson the confusion, and I have a 152 page manual on the wrx wiring so that should help.

But yea, early thanks to any and all help it'll be much appreciated....

get an aftermarket EBCS, like the GrimmSpeed or ixizconcept one.
The vacuum lines and whatnot can either be recycled or just made out of whatever heater hosing you can find at an auto shop.

You're going to have to track down the Fuel Control Unit if it wasn't on the harness.

Any updates on this? This is something I am considering on my 96 LGT wagon since it seems to have a lot of drivetrain issues.
