Default need some help with parts decision

well i am new to the subaru world but not new to performance,
i have serched and cant find the amswers i want. i have an 02 wrx wagon that i bought with a bad engine,runs but knocks very loud. i intend on building the engine myself.asuming the crank rods and pistons are all junk,i would like to install a new subaru crank,with forged rods and pistons.

my goal is 300awhp.here are my questions,is the stock crank forged?will it hold 300whp?
what rods should i use?was looking at the eagle h beam or the manley h beam.
what pistons?was looking at weisco or je.

i have never driven this car due to the bad engine,so i would like to build a stong bottom end,since i need one anyway,and put it together,drive it and go from there.

any help would be great thanks in advance

stock crank is good for 800+hp. stock sti rods are good for 500ish hp. stock pistons are junk. anything forged is a massive upgrade. i like arias and je but many people have their own preference.
