After insatlling a 6776dbb turbo, 60# inj and numerous other parts on my 50,000 mile car I was not impressed. I have troubleshooted the lack of power and upper rpm sputter issue for months.
I will make a long story short. Pulled engine and found:
loose timing chain
stock cam worn on all lobes(not wiped out)
all lifters were worn..(indented in)
all rings were shot...2 pistons almost slide out when removing rod bolts
4 bad valve guides on the heads
This is great news because now I know what the problem was.
New roller cam and lifters being installed along with all necessary machine work. I hope there is a substantial gain in power and I will finally get to see what that turbo can do.
