Seeing as nobody sells a forged crank for the lowly LN2, I decided to look into having a 4340 done up. The only place I've found that will do it is Crower, and they quoted me $2500 and 14 weeks. Obviously, a one-off piece is going to be pricey, but, yeah.
I know this will never be a production piece anywhere, but I would assume as the quantity goes up, the price would go down (seeing as the second piece is 50 times easier/cheaper to manufacture).
Is there anybody out there that would SERIOUSLY be interested in buying one of these? like ~$1500, maybe?

Exactly, if you are that worried, have some billett main caps made up

A good amount of power, maybe. But what happens when it no longer holds? I'm just trying to avoid cutting ANY corners this time around.
Besides, I could use some extra displacement...

You expecting to make over 500hp on the stock crank?
Don't stroke your engine, especially with a turbo, its the worst thing you could do for a rebuilding. If you want more displacement, bore the cylinders, if anything you'd want to shorten the stroke. Changing the stroke by changing the crank will round out your cylinders, there was a stroker kit for the 2.2 a while ago, but its now longer sold because it destroyed more engines than it helped.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
I'm 99% sure the stock crank won't hold it...so, no. Hence the need for higher-grade
Cylinders are already .040" over, don't really want to risk any more. That should give me some lee-way (sp?) in the stroke, correct?
I remember a 'stroker' kit sold by some BS company a while back...didn't hear of anyone actually using it though...

you May have to talk to someone iN a machine shop like JBP, They sell Cranks that are specific as well as custom.
JBP Built 2.4
250HP
230FT
Dont race
But dont push it
Already talked to JBP, they only have the V6 crank, and they sell the Eagle ecotec crank. No LN2

Ron,
wouldn't you say that 500hp on the stock crank is a bit much?
to just throw that number out there like that, I hope no one takes it as the gospel.
