You need a few parts as well. Does this intake have the aluminum cross over or is it all plastic?
The parts you need is the coolant tube that runs in the valley between the heads for the PI intake, water pump nipple and the alternator bracket for the PI intake. You will need to use the PI gaskets and RTV around the coolant ports, you will see where once you put the gasket on the head. I have posted pics before but I am not going to find the link or the post.
If it is the all plastic intake, I am not sure where you can put the other sensor. NPI cars have 2 temp sensors, PI cars have 1. If it is the aluminum crossover, just tap and drill it for the heat sensor.
