ok so im still wondering about this motor. why am i seeing so many posts in other forums of people asking for diagrams and such of this motor if is crap to use??!?! did all versions of this motor have issues?? i would have assumed that a jdm motor with 40-60k would be a perfect conversion candidate if it was well maintained. and with 280 hp stock im beginning to wonder why i didnt try it out myself???
granted, you do need to find a vaccum/solenoid box, but if you did find one, and you happened to find a great jdm motor for super cheap (ebay maybe) why not try it out?? only other thing youd need is a new high torque starter that will clear the secondary turbo (one that i already have)
this guy did it with fairly little trouble and documented the whole build!!----ubber nice job too!!

on wikipedia this is all i could find about that specific motor and any issues with it...im surprised it was used all the way till 2003 legacy's!!! why keep using it if it sucks?! they only changed it to a bigger single turbo after that. i would rather have full boost at 2000rpm!!!
"Turbocharged versions continued to be available in most non-US markets. Speciality touring and racing versions were available in Japan, as well as the DOHC 2 liter twin sequential turbocharged (EJ20H) version on both the Legacy RS sedan and wagon, listed as "Boxer 2-stage Twin Turbo" on the engine cover shroud. The twin turbo can only be installed on right-hand drive vehicles because the turbo on the left side interferes with both the brake master cylinder and steering linkage, among other things. A minor performance problem with the twin turbo is there was a "turbo dead zone" that surfaced between the transition from the first turbo before the second turbo would kick in around 3500-4000rpm. A continuous traction delivery system, called VTD by Subaru, was used with all JDM turbocharged vehicles with the automatic transmission. The VTD AWD system is a permanent AWD due to its 36% / 64% split."
i assume that "dead zone" could mean low boost there or something. or a drop in boost slightly. but at wide open throttle you would probably hardly notice. most of my city driving is done below that rpm so ide be good i think. highway maybe at like 3200 the highest-even with my 3.88 r/p!!
found something to fix the "dead zone" issue. a simple ecu reflash....

what im saying is, if you maintain the car well, and dont race the crap out of it, shouldnt it last just as the others. why is this such a motor to stay away from specifically?
