A stock 300ZX Twin Turbo’s stock recirc valves commonly produce a sort of “goose honk” sound when relieving pressure. This is nothing to worry about and is quite common on other stock turbo cars as well. You can address this noise by switching to a different style of bosch (or comparable) recirc valves, or converting to a BOV setup on higher horse power applications.
