    Hey man,

    I was reading a thread post of yours about overboost on the JDM VVT-i stock twins. I had read somewhere that the 2nd gen twins in the VVT-i version definitely had steel internals rather than ceramic like the 1st gen twins. Did you ever have your stock turbos apart where you could verify this? Reason I'm asking is that if the wheel is in fact steel, then overboosting due to not having a 2" restrictor in a catless exhaust shouldn't be an issue any more than it would be with the USDM turbos, right? Thanks.
