Got a notch top sr20det, turbo seals are on their way out, i know that, but when i crank it up to 5000 rpm + i get this rattling, grinding sound coming from the engine. its pretty loud so i was leaning towards the turbine is just movin when its spooling that fast. any idea’s would be appreciated, thanks ---

had something that sounds similar, Does it only happen in boost? like if you take it to 5000 rpm but keep it out of boost does it still make the noise? because mine wouldnt turns out i had blown the gasket between the turbo and the manifold and it would make this horrable metal buzzing noise under boost or serouse load. could be worth a look. ---
