What boost pressure can a stock 96 impreza wrx handle?

A stock 1996 Subaru Impreza WRX can typically handle boost pressures around 0.6 to 0.9 bar (approximately 8.7 to 13 psi) without significant risk of damage. The factory turbocharger and engine components are designed for this range, ensuring optimal performance and reliability. However, running at the higher end of this range can increase stress on the engine, so it's essential to monitor for any signs of knock or detonation. Upgrades to supporting modifications can allow for higher boost pressures safely.
