If you happen to have a FWD impreza, here are some things of note:
FWD impreza was never sold stateside with rear sway bar or rear disc brakes.
Rear sway bar conversion:
parts needed:
2 rear lateral links w/ sway bar mounting points -OEM is easy, or many aftermarket adjustible arms to choose from
2 sway bar links w/ hardware -oem or aftermarket
2 sway bar mounts + sway bar clamp (05+ usdm WRX parts are direct bolt on and an upgrade in strength). Aftermarket like notec or MRT comes to mind as well.
1 sway bar -oem or aftermarket, you pick
2 sway bar bushings - to sit the sway bar in its mounting point in the c clamps.
FWD cars have different rear X members than AWD. the ID of the FF rear X member mounting hardware is larger than the mounting hardware of the AWD, so the original AWD inner bushing must be pressed out before a proper FWD inner bushing is pressed in to fit- This requires a hydrolic press or building your own bushing install tool with C clamps and pipes. Not for noobies or those unwilling to look for a local shop w/ hydrolic press- you will not be able to physically remove or install OEM subaru bushings w/o some proper tooling.
the good news: new oem inner bushings are $17 each at your dealer (at least back in 2000 when I did it it was :P)

confusion about ej20g varieties
hey-
contrary to popular belieft, subaru rarely does anything special in the engine department. a ej20G is like a USDM E36 M3, its nothing special, and even less trick than the 1 throttle single vanos (as compared to the 6 throttle 320ps, smg, Eurospec double vanos car).
the wagon engine is BETTER than the sti, BETTER than the sti-RA, Better than the wrx-ra.
ej20G= all 1992-1996 2 liter turbo engine. all were DOHC 4 valve, all had same heads, same block casting (there were two, the open deck is much better than the oldass garbage closed deck). All cams were same, all valves were same, ONLY the 1994/5/6 Sti-RA and Sti-RA V-limited ONLY (none others, and i mean NONE others), had a mechanically actulated valvetrain instead of the hydrolic lifter. This was a high performance modification, not a street car part. Those parts are not designed for daily driven car use. you would be best to leave them in a track only car, not street car.
the wagon motors are less beat on bc of the smaller turbo. Everything else is the same, all eletronics, only the turbo and ecu are the difference between WRX, WRX-RA, WRX wagon, STi, Sti wagon. All longmotors are the same for the most part, all cranks and rods are forged, some pistons are forged, some are hypercast - the hypercast ones are more durable and weigh the same. they also can take on limit 30 psi of boost before other things become unhappy.
if you read the post, it pretty much details the entire part structure of the car. Its custom combination from the best of subaru OEM offerings, diff and corners from 2004 ver8 gdb, trans from ver2 sti-ra v-limited, engine from low abuse wagon, you would be upgrading the turbo and fuel system regardless of which ej20g varient you picked, as they are all the same and all fall short at the same power output (which oem hits easily) at 320 crank ps. Injectors are all 440cc and max 98 duty about there.
