Good Question....
I dont know exactly how hard it is but i do know that max psi performance sells a kit. It says it includes a new timing cover. So that in it self is quite involved. Cables should not be a problem once the APPS sensor is off. the kit comes new lines because the injectors are on the opposite side on a 12valve. other than that one hot wire to the shutoff solenoid and i would think that you will be up and running. i dont know how you would keep the check engine light off because the vp44 would be disconnected. but other than that. IT is somewhat involved
