Turbo Scratching Noise

[driver4567]

Hey guys, I've got an R34 GT-t with a standard turbo and intecooler, standard air box, and a big but silenced exhaust. (It was at 110db, so i had to fit the silencer)

My problem is that my turbo is making more and more of a scratching noise each week. I sometimes don't let the turbo timer go for too long, and i think that is adding to the problem. And I think the silence is messing up all my pressure, but i don't know if this would mess with the turbo.

Early cold mornings the scratching noise seems worse? which i can't understand why. Or maybe thats another noise.

But all the time when accelerating with boost i get this noise... What are your throughts on the noise. Do you think the turbo might be burnt out, and flaking. Is it time for a new one?

I plan to remove the silencer shortly and compare. I'll see how I go then and let you guys know.

PS. I'm still not too used to the car, and don't know what is and isn't a normal noise too well.

Thanks

pull the intake stuff off the front of the turbo and move the front wheel of the turbo up down left right. it shouldnt move much at all but it might be touching the housing when boosting. this means the turbos broke. so put a bigger 1 on

do a search but sounds like you have a leaking exhaust gasket
