    IMO, reducing CR isn't right for now at least. If the fueling problem was solved and there was high HP kits available, then you would be on something. But with reducing CR you are losing some HP because in future there might be high HP kits and you might go on that route and ...
    Not worth it IMO.

    +1, unless you have your mind set to see how far the engine will go without poping, it is always a good idea to make the block reusuable. Go over on the walls a little, source the right rings, pistons, rods, bearings and wala.

    On this particular car, unless you go past the 7k rpm redline, a piston crown will be the first to go as its already been proven to be the weakest link on this car...rods won't come out the side of the block first on "this" engine

    For me personally that is not relevant as I will not go with a single turbo kit anyway. I prefer being able to use the RB equipped car to its full extent without having to worry about breaking any internals.

    Certainly you'll be fine with sticking to the RB's on stock internals.
