Today took of my hard piping to mod it alittle and noticed some metal shavings in my cold side piping. Took off hot side piping even more. Recently I changed turbos from evo 8 to brand new Fp green about a month ago. The car has only been started a few times with maybe 5 mins of run time on it. The previous turbo started messing up and wouldn't build boost so I converted to green. I checked the jpipe on the Fp and don't see any shavings the shavings look like aluminum. Could it be housing?? It's not ferrous cause I checked with a magnet. Don't think it's stainless. Engine on has 28k original and runs mint. Has anyone ever experienced something like this?

 

What intake do you have? I had an injen intake with my fp and the filter rubbed against the hood leaving shavings in the intake piping.

 

Ets with a K&n.. Everything is basically new. The only thing I Can think its from the old turbo. The new Fp has zero shaft play spins perfect and has less then 5 mins of run time so all the shavings have to be from the old turbo. It wasn't making boost over 10 pounds and couldn't find out why, I'm assuming it was internally damaged since it didn't make much boost

 

Sounds like a mystery i can't think of anything lol never heard of this

 

My only thought is something inside the turbo was hitting part of the housing, the flakes looked aluminum.. That's all I got this car is pissing me off lol

 

Look at the comp wheel of the green to see if it looks like it clearanced itself on the housing.

If you managed to blow shavings through the intercooler, there has to be tons caught inside of it.

 

Check the wheel on the compressor housing for damage?

 

Checked the Fp everything looks perfect, spins perfect no shaft play and nothing inside the new evo 9 jpipe. The hard piping I have was on with the older turbo And had a alittle oil in the piping which caught the shavings. The only rational explanation is that it's from the old turbo which wouldn't build boost. Now that I remember it did make a funny whine before I took it off. Or its from when the guy who fabbed my piping and cut my ets intake for clearance with K&N air filter under the hood, maybe had some savings inside but he builds a lot of stuff he ain't sloppy. Only thing to do is drive it and see if they reappear. I cleaned everything really well, so fingers crossed

 

Was the compressor housing ever ported?

 

it's the surge port cover I don't know of its ported to do that or just built that way

 

Its possible that when the surge port was machined, someone didn't do a good enough job of cleaning out the housing.

 

Man that's intense. Keep us updated. It sounds as if it may have been the previous turbo

 

Clean everything out and see if it continues, that's scary...

 

sounds like old turbo to me as well.

 

Did you figure it out? Do you still have the old turbo to see if it clearanced itself? Sure sounds that way. Especially with the strange whine sound you heard before it no longer built boost.
