Dear all,

The boost of the turbo dropped, from 11 psi to max 5psi,

Adjustment did not change,

I drove with this turbo, 150,000 miles,

Getting similar rebuild turbo charger, but not a wastegate,

For $109 new wastegate from Taiwan, Mamba Tek, including shipping,

Q. did anybody use them?

Q. does anybody know the size of the valve 23.16mm,

will send them this Q.

messuerd the valve O.D it is 31mm,

now will see where is the problem,

did ask Mamba Tek if the have this kind of wastegate with 31mm O.D

Found the hose from ALDA to intake manifold was hard rubber and disconected,

put a new one 65 miles up the hills,

Harts my ego, and getting a rebuild turbo charger,
