For a few weeks now, when you accelerate there’s like a siren type of noise until the turbo whines and the whine sounds like a drill. Took it to a mechanic and they couldn’t figure out anything as there’s no check engine light and very minor if any performance issues. When you floor the pedal, there’s a slight hesitation then full power, and higher gas consumption

Buy a used Saab oem turbo for $200 and bolt it on. Make sure and clean the oil feed line and prime with oil. Use synthetic oil. Rebuilt stock turbo is about $600. Cheep turbos new on Amazon and etc are around $200 but are junk.

I got the turbo put all the way in except for now I couldn’t get the lower coolant banjo bolt to stop leaking. I found out there’s 2 washers needed so I put two on the top one and when I went to put two on the lower one it stripped the inside a little. Is there anything I can do? Is it ok to use loctite or anything?

There should be a copper crush washer top and bottom of the banjo bolt not 2 or you could strip the thread , lock tight may cure the leak but for how long ?
If its the bolt that's stopped the thread then new bolt and crush washers required.
If its the thread in the turbo then helicoil is the only way but make a 110 % sure no swarf bolt enter the turbo housing .
