with my longtubes in the mail. I am about to buy a pi intake. I have read that you must also buy a new alt. bracket and lower coolant hose, and some RVT as well. the intake i am about to buy comes with the lower coolant hose injectors stock TB all that. so it will just go on. and my 96 has an updated npi intake with the aluminum X-over. would I have to buy a new bracket? or are all aluminum X-over alt brackets the same? what am i missing. this is my DD and it cant be down to long. thanks
first of all, if that updated NPI intake is a ford part, you have it made. you wont have to buy the alternator bracket, you will be able to reuse your NPI one, all you have to do is swap over the crossover from the NPI to the PI intake (6 bolts under the manifold). this way you dont even have to drill and tap for that extra coolant sensor.
if the intake you are about to buy comes with the fuel rails and injectors, its not going to work perfectly, you will still need to swap over the fuel rails at the very least (injectors are the same, fuel rails are different). throttle body and plennum are the same throughout the years, so you can reuse that too.
so to recap, if the NPI manifold you have is a ford part, you will need to buy:
1) PI coolant nipple (need to remove water pump, hammer the old one out, tap the new one in. this is the nipple where the return tube plugs into)
2) PI coolant return tube. its the coolant hose that goes under the intake.
3) PI intake manifold gaskets, preferably 99-01. these have a slightly larger hole for the coolant passages so it doesnt block the flow too much.
4) RTV to make sure you get a good seal around the front (passanger side) and rear (drivers side) coolant ports
and thats it.
