For those of you who would like to know...

It was a stock flywheel with a stock gtr clutch plate in a rb20.
and the hole is in the GTR hood he had on it.

Also the guy ripped chunks off the block from it and the engine is a complete write off.

The consensus is that this was caused by a broken engine mount. The torque then is applied to the gearbox case that lets go and takes the clutch and flywheel with it.
