1990 Legacy (motor-turbo-etc) :)

Well, after some months of getting parts together the Legacy runs again. The bad part is that this car was supposed to be the "back-up" to my DD WRX. Well, that didn't last long as I through on turbo parts and committed to low boost 
Within three weeks it destroyed a headgasket with nearly 200k originally miles on the ODO. Granted this car was taken care of very well before I ever got it by an older lady. Oh well.
Plan two was to either build the motor or find another one. My buddy hooked me up with a 2003 Forester 2.5L motor (low miles ~30k). I rehoned the bores, and got two new STi "B" pistons, two new "A" pistons (rings, wrist pins, clips and all), ACL race bearings in standard size (the journals looked great), Cometic HGs and lastly a set of STi rods. I used a WRX oil pump spring and shimmed it with three shims. The heads I cleaned up very nicley.
I installed the entire motor myself the day before last. I had a 3.00" downpipe/mid-pipe welded up to a WRX axleback and put about 90 miles on it today (surpirsingly quiet). This has been the simpliest build thus far
Can't argue with the hydraulic-lifters for ease of install!
I took it out on the road earlier (SAFC + modified FPR) and did quite a few WOT runs as well as part-throttle to get the AFR dialed in. Only running max 11.6PSI with a VF39 and WRX TMIC. The car feels strong. Probably a good 101-103mph trap in it as it is. Compared to all of the WRX and STi's I've tuned on our dynos (Dyno Dynamics) this car will probably puts out about 215whp as it is and maybe 250whp (93 oct) once I get the Haltech on it and turn up the boost. I figure that'll be enough for the 4EAT trans. Well, I have no clue about AT based cars so I hope it holds together for a little while.
I'll let you guys know when I put it on the dyno. Soon hopefully but I'm about to get busy with the PRI show in Orlando coming up the week after next.
Edit: I forgot to add the exact mods. They are:
2.5 STi rods, 2.5 STi pistons/rings, Cometic HG .051", VF39, Megan Racing DP, STi UP, 3.00" mid-pipe to factory WRX axle-back (all catless), SAFC, larger style WRX TMIC (had to mod the TB to fit it), NGK BKR7EIX plugs, modded stock FPR using 92-94 redtop injectors (I will go back to a stock FPR and use modded red injectors later on). newer style 'square' motor mounts. That's about it.
