You can upgrade the turbo for a bit more top end if you really want it and it will be perfectly safe on stock internals as long as it's tuned for correctly (i.e. keep boost below 22 psi). But yes, stage 2 (what you have) is considered FBO and pretty much as far as you can go without upgrading anything else to support.
