A V6 biturbo engine is more highly stressed as a racing engine. Far more susceptible to temperature, inambient & oil and water and air. With vulnerability in inducting dirt and sand in the intakes. In having those 2 snails on there that are prone to falling out of balance, perhaps more especially in a variable boost environment we might see in the future. Data from the engines will probably need to be pored over, see where overboosting happened, temperature, and any other thing that could impact reliability
If you are 888 and throwing a fresh engine in for almost every event, the budget impost wont be a whole lot. If you are running the long life method like most other teams, the goalposts will shift.... in the hip pocket..

650hp for a 3.5 litre turbo motor (On E85 at that) is not stressed. It is not even close to being stressed. An R35 you can buy from your friendly Nissan dealer has near on 600hp and runs on petrol. Comes with a warranty too.
And overboost? Their biggest problem is likely to be turning the thing down far enough to get parity with the atmo motors.
