Alright, so I picked up this 99 GT with a cracked plastic crossover pipe. Time to upgrade to the upgraded metal PI intake. But, what do I need to install it? I read I need the 01' up Alternator bracket, I know I need intake manifold gaskets... Heres a list I found from ebay, but do I need all this stuff, am I missing anything?

PI intake manifold gaskets (2 pc, L&R)
Water Pump O-Ring
Water Pump nipple (new style)
Thermostat housing O-Ring
01' up alt bracket
set of 16 replacement fuel injector o-rings.

Why are you replacing the water pump nipple? Is it leaking?

The parts list I gave was from a kit listed on Ebay, didnt know if I needed all of those items. That was my question. What do I actually need to replace/order to install this new intake manifold?

MaxxRPM

Don't know what kit you're looking at but beings you already have a PI motor, all you will "need" to install the updated intake manifold is an 02 and up alt. bracket.

For the install, I would suggest;
1. New intake manifold gaskets.
2. New thermostat and gasket (O ring).
3. New injector O rings.

You shouldn't even have to mess with the water pump......period.

Ok, sweet. Thank you. Lastly, how many injector O rings do I need, is it one or two rings per injector? I read somewhere it was 16, then somewhere else it was 8. I would like to have all the parts ordered and in hand before I tear into it, want to bang the whole project of draining ALL the fluids and filling with new plus this manifold in one afternoon.

You Will Need 16 Injector Rings, Top And Bottom For Each.

Alright, thanks. The guys at the parts counter are NOT helpful in that regard. -_- Alright, got my list, time to hop on to rockauto or something and get em coming.
