Help! Timing chain broke
 

Any advice greatly appreciated. Mazda cx7 2008 169,000 miles.
Broken timing chain, gaskets, oil pump antifreeze hose leak all just fixed.
Mechanic tells me on test drive under boost code comes on when accelerate on highway. Po299.
Do I need a new turbo too?!?!?
Or now that the turbo is getting oil it's just in shock...I had several major oil leaks.
