Intake ports are different. Also aluminum cross overs will be one thing, however PI intake manifolds only have 1 temp sensor (oe) where as the NPI cars require 2 and thus having to be drilled and tapped for the PI manifold.

correcto ^. also the npi manifold has a plated gasket(prone to leak especially with aftermarket upper manifold elbow) like the manifold to head gaskets. the pi has the rubber gasket ring.

well my car is stock but ive looked at it and it has the aluminum crossover

 

[dirtysnowball302]

well here it is 99 to 2000 or 2001 they had a pi intake with a plastic cross over but..if you u buy an updated intake it will come with an aluminum cross over with both temp sensor holes already tapped..an the difference between pi an npi is that npi has kinda looks like a circle with a dogleg an the pi is more rectangular an also has a dog leg, What year is your car?

underneath the intake itself is about 2 inches deeper. better flow.

 

[dirtysnowball302]

You can definitely tell the difference with the port shape. NPI intake/heads have an oval port where as the PI intake/heads have a more rectangular port. Also with PI intakes the have a deeper dome that sits in the middle of the valley so if you ever decide to do the PI intake swap with NPI heads you want to make sure that you have the coolant tube that runs down the center or you'll run into clearance issues when your laying the intake down on the heads. Also make sure you silicone the HELL out of the coolant ports on the heads when laying your intake down or you may run into coolant leaks as I did a couple times.

thx guys for all the input really appreciate it really wanting to do this swap...just need to find the $$

 

[Ninety8stang]

You can find a decent PI intake for around the $70-100 depending on your seller and the location.

Wrong, no PI manifold ever came tapped for two sensors, just the one on the pass side. the tap is very easy to do though.

 

[dirtysnowball302]

i have one if you want to buy it. im in FL. ill sell it 80 plus shipping. but it dont have the cross over...if you want to buy new it will cost you about 200 somethin. those things are expensive

 

[blacknotch302]

dirtysnowball302 u have a pic?

 

[dirtysnowball302]

i can get one for you....an just to let you know they do come taped..i have one. buy an upgraded metal cross over one an it comes tapped for two..thank you

 

[joekd]

Correct, you can get a non-pi metal crossover with 2 sensor holes that can be used on a PI intake but again not a single actual PI intake ever had 2 sensors

 

[dirtysnowball302]

again....i just bought one.. pi . ill show pics. i never taped it

 

[vermilion]

the pi intake dips way low in the block valley. you can not miss it.
