Matt's NSX has Methanol Injection which allows us to raise the boost by a couple of psi. We would never release a customer car running 12 psi on a factory motor without Methanol Injection and the additional failsafes that we incorporate.
Since late 2005 we have turbocharged over 40 "stock" motor NSX's and have yet to see a failure directly resulting from our tuning or turbo system. If the system is installed and tuned by a competent installer(such as LoveFab) then the factory motor should last many years.
400 WHP was the "accepted" safe power level. But with the advance in technology, the power levels keep rising along with the safety levels. For example, we have a Meth Injected stock C32B making 479WHP/340WTQ at 10 psi. The car has seen multiple track days and contintues to take a beating. The customer has driven the car more over the past 18 months since than when he bought it new in 1991.
LoveFab has always fought the stigma of turbo = unreliable. We are slowly but surely winning the battle.
