I just want to make sure I have everything. Should I replace all of the timing belt pulleys when I do my longblock swap? The picture below shows there are 3 pulleys and one thing that looks like it has a gear on it. Does anyone know the part numbers for these parts? This is for a 04-05 STi motor
Integroid carefully inspect the crank gear pulley too for cracks. They are known for cracking and breaking a few teeth off.
The water pumps rarely fail if at all. I have never heard of a water pump failure. Maybe ask King if he has seen a wrx/sti water pump failure.
