Default EJ205 build, need input and advice!

So I've got a 04 Wrx wagon that recently went belly up on me .
Misfiring on one cylinder and same cylinder has considerable loss of compression determined by Pacific Import Auto. Also burns a lot of oil as would be expected. Diagnosis is lower end damage either a rod or piston.
So considering something like that would require a lot of work as it is, I've accept the good with the bad and am taking this opportunity to start my build.
Really not looking to push an insane amount of power since I'm in high school and daily drive it, looking for a safe 400 after I upgrade my turbo this summer.
What I've got:
-vf39 (19psi)
-Sti injectors (realize these will need to be upgraded soon)
-walbro255
-Sti TMIC
-Perrin up
-Cnt racing dp
-borla catback

I'm going to have my block bored and honed and have a valve job done and then I was looking at...
Pistons
Rods
Valve springs and retainers
ACL race main bearings
Arp head studs
And also am going to do a tgv delete

I'm really looking for any input or experience at all, I'm doing all the labor myself except for the machine work and assembly of the motor. I just need to know if I'm doing anything stupid or are missing anything. Also when I take the block for machining, should I just have it honed? Or should I bore it out to fit a bigger piston? As I said really just looking for any helpful input and anything to steer me in the right direction. Thanks so much!

What is your budget? When do you need the engine completed?

Your best bet for good results would be to have PIA rebuild it. They are a reputable shop with lots of quality builds.

That's my plan. Trying to make money right now to fix it but I'm not looking to spend more than about 2500-3000. I'm doing all the work myself except for the machine work and actual assembly of the motor, I'm going to have pia do that. (As well as tuning) As for when I need it completed, as soon as I come up with the money. It's my daily driver so it's a real pain in the ass not having something to drive.
