First, let me say that i have researched this topic on more than one occasion and never seem to find a clear answer, so please don't flame for asking this one.

D16Z6 with AEM truetime cam gear and stock crank pulley. I need to know which of the 5 marks on the crank should be used to line up TDC for timing the crank/cam. (theres one group of three, and one group of two which includes the white mark that im timed to now)

the head is timed right and the car starts and runs, but its bogging down when i give it gas. The only thing ive done since this car ran fine was a head gasket, 5spd swap, cam gear, and fuel rail, but i lost time when i pulled the head and im struggling now to get it back. My only other concern is that i could be the AEM fuel rail i installed? Stock injectors, stock regulator, everything stock except the fuel rail on the fuel system.

Any input would be greatly appreciated.

 

Sounds like the mechanical timing is correct. Have you also set the ignition timing to spec using a timing gun and having the service connector jumped?
