Haha, sorry this made me LOL for like 10 minutes.

Sorry about your luck, chances are the car isn't making boost because there is no compression. Draining your oil and looking to see if its milky will tell you if you warped the heads and blew the HG.

The car has no safety measures it just dies.

Yah totally a safety measure when it overheats it magically makes the exhuast vanish instead of flowing through the piping to make the turbo spin. The ecu isn't going to control the turbo without a boost controller of some sort, even then its going to depend on the wastegate spring for boost. Seriously look up how a turbo actually works, if that's too hard just pay someone to do the work. Could be a wastegate stuck open but doubtful, more then likely a blown hg

Yah its possible with no oil in the coolant, I've seen it pressurize the coolant system and none leak into the oil before. If engine shuts down from over heating that's likely the cause. Higher pressure makes it harder to boil coolant but it means your pushing air into the coolant system which increases the likely hood of overheating. You can pull the wastegate and see if its getting stuck open but like I said its doubtful. Engine is likely going to need at a minimum a hq, possibly heads decked too

IF the motor is running and you have no boost, but drives like stock, sounds like Your IC Pipe or gasket blew. check and see if you lost a coupler or something. Happened to my buddy's M3 he just ripped a Silicone Coupler, tightened it backup and it was all good..

Check for exhaust leaks before the turbo as well.

May have just been a coincidences that something got loose at the same time as your overheat issue.

How did your car overheat? How did your fans fail?
Were you doing a pull or what? Things don't just decide to stop working or start failing.

Agreed... if the engine is functioning properly, oil is the right color, then you must have popped a coupler off. When it happened to me it felt just like this.
