Default 2010 WRX engine rebuild/build. Need Advice!! Thank you in advance.

WRX started clicking after car wasn't re-tuned for winter E85(tuned car myself because I wanted to learn = bad idea). After about 200 miles engine lost power and timing was thrown off by possibly bent rod or ruined bearing. Car will no longer run but will still turn over and start but dies instantly. I need to get her rebuilt. I am nervous because I normally do all labor and work myself but don't have tools, space or expertise for this job. I need someone with a little more experience to look at rebuild plan and build in general to offer advice on how I can save money without compromising reliability and what I may have missed. I also am overwhelmed by choosing a affordable turbo so need help with that too. Shops that I have looked around out want to charge 2000 labor and 800 for tune you probably know price of parts so im not gonna waste time finding price on everything atm. I may be able to squeeze out 7500-8000 for everything.

Car has:
1000 CC modified and flow tested stock injectors
Turbo back exhaust, glasspack muffler seemed to be restrictive so may need to be cut off.
Upgraded uneven header and up-pipe.
Grimmspeed BCS.
Walbro 255LPH fuel pump.
Mishimoto J-Series FMIC- Not installed.
Wide-band 02 sensor(not really relevant.)
Maybe something I'm forgetting but I think I got everything important.

Parts I am going to purchase for rebuild:

I got a Mishimoto j-series intercooler brand new on ebay auction for $120 (haven't ran pipes for it yet).

IAG Stage 2 Short Block. Not sure if I need wrist pin and cover seals though ( was thinking about stage 2 Tuff block but figured id save money where I can).

Full Seals/gasket kit.

Killer bee oil pickup.

Oil Pump.

Turbo able to safely run at builds potential without over stressing it.

Wish list according to how much is going to need replaced on my budget:

Ball bearing turbo.

Cams.

Tranny reinforcement brace.

E85 winter and summer tune to prevent 2 dyno sessions.

400+ WHP
600+ WHP Potential for block and turbo without blowing them up and minimal turbo lag at current HP.

Future upgrades.

Breaks and Suspensions upgrades before anything. (would have done this before engine build if it hadn't have blown up)

Fuel rail and lines.

possible 2nd fuel pump.

1500+ cc fuel injectors.

You don't really need to do cams/head work if you're looking for 400whp. Save the money and just do a refresh of the stock heads.

A walbro 255 is not really going to be enough fuel pump; consider an AEM 320 or better yet, a walbro 450 (though you'll need more modification to do so).

Where are you located? Someone might have a shop that they can recommend in your area.

Just keep in mind, now is the best time to upgrade, since everything will be taken apart anyway. That said, upgrades add up quick. Nevermind the stuff that no one ever considers in their informal price list (AN fittings, timing belts, hoses, TGV/air pump deletes, the upgraded inlet you'll probably need, etc.).

If you're having a shop handle the rebuild, $8,000 with all of the upgrades is probably way optimistic...

My engine recently got the dreaded knock and have been looking at options. I'd be really curious to hear what you ended up doing and what you think so far.
