Most shops quoted around that figure.It's not cheap to do a timing chain. That $2600 seems high though, given the motor is never actually being removed from the car. I can say having the engine out of the car how freaking hard it was to pry the timing case cover off the engine with that RTV sealant they use. I'm using Loctite sealant which is soluble in air so the covers come off super easy next time yet don't extrude into the motor.
I'd get another quote though.
