Post Rebuilding A Blobeye WRX

So I have a 2005 WRX with 152000 miles on it. It runs 17lbs of boost on a stock block and stock turbo with full bolt ons and e85. I am wondering the average cost to rebuild the motor (possibly upgrade parts while i'm at it like pistons, rods, etc.) and have a shop do the work for me as I don't know enough to fully rebuild an engine by myself. If anyone has experience with this on a wrx or has recommended parts i'm trying to gather as much info as I can on it before I start this coming winter. (My budget is to hopefully stay below 5000)

If you want to rebuild the EJ205, standard rebuild usually includes new crank, rods, bearings and forged pistons.

You can use the updated OEM crank
You can use new or used STi rods
Kings bearings are used a lot but there is also another brand I can't remember right now
New forged pistons as opposed to the OEM cast pistons

Deck the block & heads
Rebuild the heads - possibly all new valves ( I would ) and new seals
Probably fine with current cams and springs

Having someone do that for you is in the $5500 area.
Pistons usually depend on the Builder's choice so talk to the Builder first. They like to use what they find works best for them

You still have to add:
- R&R of the motor & transmission
- New clutch kit
- Possibly new clutch master & slave cylinders
- Check over all exhaust pieces and replace as necessary
- All new fluids
- All this is above the $5500 for the motor

Basically, if you budget is under $5000, you can't afford it.
Another option is to purchase a used JDM motor out of Japan from a reputable importer ( JDM Racing Motors & J-Spec Auto ).

You could buy a JDM EJ205 for ~ $2000 complete, not including labor for the motor swap & additional parts ( see "You still have to add" )

Well this is y daily driver so I wouldn't need anything absolutely special done, I was planning on buying a used engine and having it basically refreshed to work well and a lot I have researched since i posted this said most people had it done for about 4800 on the higher end so I was just wondering if i put in things like arp head studs and better bearings and just little things as a sort of insurance policy how much extra that would be and what are good brands to use.

Buy a jdm wrx ej205 w/ avcs for 1000-2000 and swap it in. Just need to wire in the avcs and get an ecm and tune. Its a simple, cost effective swap over rebuilding the USDM ej205
