Dan's Blown Motor
Well that's what I found in the oil pan
Piston #2 had a catastrophic failure. Im guessing it started when the bearing spun, then it starved of oil, then failed, then the rod slapped around and when the cap let go the crank grabbed the rod end and mashed it thru the block.
You can see the neutral shaft is scarred. Also the crank and bedplate are all scratched up. In the last pic you can see where the force actually cracked the bed plate. I think the pistons might be ok...at the worst may need a new #2. Neutrals might be able to repolish and be fine. But the block is toast.

"Turbos are easier on motors than blower. I bet the stock piston could handle more power on a turbo" Quoted from many turbo fan boys. LMAO!!!!! I knew it was gonna blow, I knew it wasn't gonna be a piston too. I didn't want to say it was gonna be a rod or something really bad, but look what a turbo got ya 
Blower = Blown ring land - $700 and some hours of work gets you back on the road
Turbo = Destroyed block and internals - Many thousands of dollars and hours and hours of work and labor until its back together

when a rod bearing gives. it most likely seizes on the rod. rips the rod in half, or finds the weakest point and proceeds to put the bottom end on puree. destruction of anything and everything around said rod will happen in a milliseconds.

It blew up cause the rod bearing failed...that can happen reguardless of its mode of aspiration. It was most likely something we f'ed up when reassembling it.
Rods are forged from factory so there was no real reason to change em out...tho if I do it again ill do aftermarket forged rods just because most likely.
Once again turbo is not the reason for this failure...quit being a s/c fanboi. IIRC your motor is STILL in pieces.
Also my stock internals were fine on both blower AND turbo AND in mint shape when I removed them from the block...I rebuilt the motor cause my timing chain tensioner was never extended from the factory and I was in there anyway so just forge it.

damn sucks man
that looks pretty damn bad right there. If you can't find a block I do have a spare motor I was going to build up to hold you over. I could always just rebuild the motor I have in the car now, unless I have nice catastrophic failure also.
and blown..... go suck off an s/c man. Seriously get over yourself. BTW when was the last time your car was running.

great work with what you have done with your redline, your one of the few around here not scared to mod it and if something breaks, you make it stronger. When you mod, things will break, esp the more you mod. From the vids i saw your car sounded great.
good luck with the new build

Man that's toasted! It's all part of the game bro. Welcome to the blown motor club. I've killed three total to date personally! I guess I like boost too much.

lol I'm contemplating that offer lol. But he's helped me out with some issues, so just returning the favor.
I should have my forged rods soon, and pistons I have, and neutral balance shafts, and arp main and head studs, so hopefully I"ll just tear into this motor shortly before it too goes kaboom. 22psi is fun though... 25 is better
