On eBay they have kits already made up. Water nipple, alt bracket, water hose for n the valley, gaskets, o rings for injectors.

+1 but not just eBay. Quite a few mustang outlets are realizing this is a huge common swap for the 96'ers.

Known to add approx 40 flywheel hp. It's the only difference between 96-98 to 99-04 beside comp ratio

I dont want to jack this thread so only one question. When i get pi heads and intake, as well as gaskets an all, i can just put them in, and call it good? Do i Need to tune it? I dont want to spend alot of money, and i just need to change the headgaskets, but im inclined to do a pi swap while in there...

You shouldn't need to unless your doing a more major mod while doing it. I would always recommend a tune anyways. It will maximize your performance gain. A pi swap is a lot more than a change if a gasket while your there. Like said before they sell pre made up kits to help you a long the way of doing your pi swap.

There's 45hp difference between npi and pi. Plus the compression bump, your looking at 50-55hp. You'd be around 270 to flywheel, not including other mods.

Bama wont tune for pi swap, just intake swap. So you'll have to get custom tune. I don't think u need a tune but they always help.

Npi-215hp
Pi-260hp

You'll also have to run 93 gas.

Ok so just the intake manifold, would this alone be a decent improvement?

Im thinking about doing a PI swap for my 98gt as well. Is it possible to run 91 octane with the swap? They don't sell 93 in my area..

I don't know on that. I can only get 92. You could just do came and intake.

Intake swap is good for 15whp. Bama will tune for that. So both together would make a nice difference.

You dont need a tune when u upgrade to pi heads. Its basically a head gasket replacement that adds on 55hp roughly and compression is bumped to 10.54:1. 93 octane is recommended due to the higher compression.....however ive been on 87 for the past 5yrs on mine and ive been ok. But its not something im saying that its ok to run lower octane. 91 octane should do fine if u dont have 92 or 93 octane. Also if ur mechanically inclined its a pretty straight foward job only tricky part to any stang is getting the timing on point. Other than that is it worth it? Imo yes u notice the difference right away and any mods u put u can feel. My suggestions is have the heads ported and springs upgraded for future growth first. Saves u time and money down the road and ported heads flow more so add on a 15 to 20 roughly more on top to swap
and like i said imo
