Iam planing on building my motor from my 07 wrx for a blouch dom 3.0, or the 4.0. This is my plans for my motor built.

My motor rebuilt
-wesco pistions
-manley turbo tuff rods
-cosworth bearings
-stock crank
-manley valves and springs
-GSC cams
-subaru gasket kit, oem head gaskets
-ARP head studs
-kevlar timing belt
-arp case blots

-Does anyone have any of these parts. If so how were they and power runed with them.
-Power this could handle?
-Also would it be cost effective to order a pre-built from raw or cosworth.

it depends who you have building your motor, personally i like that MY motor was built specifically for me by my specs. but by no means is a raw motor or cosworth motor not worth it. they very muh so are.
plenty of people are running those parts. for a dom 3 that would be fine, even a stock engine could almost handle a dom 3. but for a 4 idk, im not too familiar with those rods or pistons. maybe a different set for a om 4.

All those parts are going to be fine for the turbo you plan on running. The most important part is going to be machining and assembly. Then after that remember while the motor might be "bulletproof" it is not tuner proof so make sure it is tuned.

You also might considering doing a oil pump upgrade.

If you use the arp case bolts you should have your machinist do an align hone with those bolts torqued down with the halves together.

For me, afterall, the clearance/tolerance checking, torque spec, torque sequence, cleanliness and assembly technics are equally important as those parts you listed.
