Z22YH inlet and induction

Hey guys ive got the chance to purchase an astra mk 5 coupe with a z22yh engine and 6 speed m32 - these were sold in Oz but not over in Uk i understand. After driving it - i noticed it lacked the throttle response of my old mark 4 that had the airbox derestricted and a ported throttle body. Just wondering if
1. the mark 5 has the restrictive airbox and can be modded in the same way as a z22se airbox
2. I can port the throttle body the same as i did with my z22se
