So long story short I was driving down the road in my car and it was running very rich due to a bad fuel map but It cleared up once I was in boost. Bone stock sr20 that has been around me for 3 years

50 trim turbo, 555cc injectors, tune Etc.etc

I floor it and It over boosted by like 15 psi (30psi) and then boom! Subaru sound and white smoke, I pull over and shut the car off and check the damage oil everywhere from the maf (piston rings I assume) fine.

So i assumed it was the pistons so I let it sit and lastnight I tore it apart only to find the following!

1.pistons are not melted or damaged

2.rings are in tact and not cracked or melted

3.coolant in number 3 cylinder but the car didn't over heat and didn't eat a single drop of coolant. the head gasket was also perfectly fine when i pulled the head off, i seen no ripped marks or anywhere it was damaged.

4.cylinder walls are not scratched or scortched

5.no pitting on combustion chamber head or block

6.valves look good but I'm doing a valve check as we speak

I am stumped at this moment as to what the hell happned! Has anyone ever encountered this before? Could the head have cracked under pressure? I would think the head gasket would give or something would melt before the head and or block would crack

I'll post pics in a little bit to show you guys whats goin down

There was a little sign of number 4 piston started to pit a little bit but nothing that would stop it from running or not make compression
