S13 KA24DE Sounds like a vacuum cleaner

I swapped this KA24DE into my s13 that had a single cam in it. Sometimes when I drive it there's this crazy vacuum sounding noise, it is most likely a crazy vacuum leak. I have having the car running and spraying around the engine with carb cleaner to see if the idle would change but I haven't had any luck finding any leaks that way. Anyone have any other ideas? Or common places for huge vacuum leaks? The car never dies on me either, always pushing strong, well as strong as it can. Also, excuse the IACV hose. Ive been meaning to change that but i cannot find the right hose thatll fit it. I may just be dumb and this sound is normal but i doubt it. https://youtu.be/PiltpCJRTSI

If you think there is a leak, do a pressure test. same as a boost leak test. You dont need a turbo to do a pressure test.
