Yes, I think it's FOD from downstream of the turbo. Judging from the color o=
f the impacted rotor face, I would say aluminum. Could be weld swarf from re=
locating the secondary injectors on the aluminum intake manifold I fabricate=
d. It's a tuned ram type that I made before I decided to turbocharge. I have=
 access to a bore scope type computer camera that I hope to squirm down the c=
urved intake tubes, to see if I messed up there

> Scott, are you using RWS apex seals - highly recommend for boost type rota=

n me (the stock ones are fairly brittle) and thereafter went with RWS apex s=
eas and never had any more problems.
