Safe from overboosting? It's possible. You might need a ported wastegate to combat boost creep. But the real question to ask here is will the engine run right without a tuned ECU (Power FC, AEM, Haltech, etc)? NO! Ported motors need some form of tunable ECU to change the timing so the motor will run right.
