Default wrx motor build up questions

ok, i there is a kid i know that has a 02 wrx motor all taken apart sitting in his garage that he will give me for free. when it was takent out of the car the rod bearing had a bunch of play in it and it was swiched out for a 20g closed deck block.

the block halves are seprated and the pistons rods and everything are sitting in a box, i didnt see a crankshaft in there though.

being that its open deck im wary of building it because i would be putting all new forged internals (pistons crank and rods) he doesnt have heads but the heads that came off his 20g block i can get for 200 bucks. the internals will cost the most.

so how strong is this block? from what ive seen places like axis dont even use this block, they instead use turbo legacy and sti semi closed deck blocks.

along with internals i will need a new intake manifold, fuel rails and injectors. if the bolt patterns are the same ill probaly go with a 97 legacy NA manifold with topfeeds or get a manifold that has the same bolt pattern and do a dual plennum dual throttle body but that may be too much.

i already have a set of headders and a turbo that are sitting around so thats covered.

in couclusion. is this block worth it to build? where can i get all the internal parts for cheap? where adn which intake manifolds and fuel systems should i look at? is there anything that i missed in my evaulation of the situation?

if all else fails i could build a pretty bitchin coffe table.

I'd say build a bitchin coffee table.
Or reinforce the block. You're going to spend a fair amount of money building up the block and you'll need to assess your goals. Maybe a used V7 block (I've seen them pop up for around $800-$1000) would be stronger and cheaper. Or you could get the desired power from a stock EJ257. I saw a few on ebay last week for $1300 and no one was bidding on them.

I wouldn't start with a EJ205 block unless you're planning on using a very small turbo.

i was orignaly thinking of using a 22t but this block is free so i thought id consider it. i was going to buy a new (at least to me) 22t shortblock and build it up and if all else fails use the one in my car when and if i get a new car.

power goals are something in the 600-750 wheel range with a 9500+rev limit using a sequential vf-x and a gt-x or something of that nature. its a long build so using my block is a last resort. that and i wanted the entire motor to be coated so starting with the block disassembled is an advantage there
