Oz rally boost

How much boost can I put through my OZ without endangering the engine internals, and without upgrading my fuel in put?

well you need a new fuel pump and fmu of sorts if you want to boost any.

5-6 psi is safe with those (as long as you can deliver enough fuel).

9psi is safe with new injectors and some way to control them (as in rrm's stage 2 kit).
