96-98 guys with pi intakes

[TangerineGT96]

soo what alll do i need to put a pi intake on. do i need some adapters where the gaskets go or what, does it really help out because i love gainin hp and im sure im not the only one thanks:SNSign:

 

[mexis97gt]

i would like to know this aswell. What sites sell an entire kit, other then the livernois kit, are there any other sites that offer a plate/adapter? what kinda prices are we looking at here

First off, I don't like the adapter plates. I have said in many threads here and other places as to why. IMO, They are a waste of money. As a minimum, you need:

PI Intake with aluminum crossover
Coolant tube that runs between the valley of the heads for a PI Intake
PI water pump tip and O-ring
PI Alternator bracket
PI Intake gaskets
RTV for the coolant ports on the heads

You can get all of the above mentioned parts for just over $200.00 new from certain Ford dealerships.

Yeap but sometimes the NPI alternator bracket will work too.

I got the Livernois kit last year for $650 , I wish now I had never got it, I have PI heads and a new motor, so I dont need these adapt plates, the good news is they are already spoken for by a friend with a 97GT.

hey thanks man that help out alot!! do you have the adapter plate on your car

 

[COramprat]

I have some plates that were made by a guy here. A little crude but they got the job done. They are all gone now though.

Check with Randy Stinchomb over on Modular Depot. There is a section that you can get in contact with him directly and he can get the parts you need. About 70 bucks minus the intake if I remeber right.

 

[98GreenGT]

I didn't use the plates, just some rtv. No problems so far car runs fine.

no, I used NPI gaskets + RTV, either do that or use the PI gaskets (that might be the best choice, the longevity of RTV when exposed to oil/gas is questionable). Also, with the adapter plate, you will need a tune as it raises the injectors and messes up the spray

runs great man. Expect your car to pull much better at 4000+ and there is a little low end gain too. Ive had it on since july and I love it. The best thing to do is to get lots of plastic baggies and label them, then put their respective bolts inside. Its all about being organized and taking your time so you don't lose anything - I dropped a thermostat housing bolt and it took me 2 hours to find it lol. Here are some things you will need in addition to what you have been told already-

Fuel line disconnect tools (dont forget these or your life will be difficult)
Coolant
Plastic baggies + marker
Permatex Black RTV
New serpentine belt (not necessary if yours is OK)
Torque wrench
Rachets, extensions. Most bolts are 10mm
Vacuum (lots of junk accumulates in the valley beneath the manifold)
Lots of rags!!! Use some to plug the ports in the heads while the manifold is off

While you're at it, may as well throw in a new thermostat (stock 192 or a 180), and replace your plugs and wires if you need to especially if you managed to leak coolant into the plug holes.

Also, you should be very careful to make sure that the RTV has ample time to cure before starting your motor. If using PI gaskets and the RTV is not cured, the coolant may be under enough pressure to blast through the silicon and then leak. If using NPIs, you'll have a damn nice manifold leak and your car will run like crap. Looking back, I should have used PI gaskets because you need hardly any RTV, and you dont run the risk of using too much and getting it in the intake ports on the heads. Here is some good literature

My own install - mostly pics

Good luck man! Feel free to PM me if you need help

just checked Permatex's site - apparently Ultra black RTV has outstanding oil resistance and one of the recommended uses is for intake manifolds

question about this site: the guy says install PI Gaskets and Non PI Gaskets. Umm which ones do i buy and which one is suppossed to be installed??

 

[TGJ]

On that link, adapter plates were used which requires the use of both gaskets. I prefer the use of the PI gaskets and not use the plates.

 

[Ducati998ss]

okay so how would i do the install without the plates?

 

[Ducati998ss]

Did u buy the stock PI Intake or did u buy a modified one? Im getting worried now because three places have told me the stock pi wont work and that u need to buy a modified one.

 

[TGJ]

Ok, follow those directions on that link. When you get to the part of putting the intake on the heads, you put RTV on the coolant port of the head and PI gasket.

I will post the pics of where the RTV is required.

The PI gasket on a SVO head, exact same intake ports and coolant ports as the NPI head.

A closeup of the coolant port that requires the RTV

The exact area that requires the RTV

The circled area is where you add the RTV to the gasket and head to completely seal off the coolant.

The other coolant port on the head. Just so you see that it does not require RTV.

Now you have to modify the intake, that link tells you how to do it. You do not have to buy a modified intake.

 

[COramprat]

TGJ is correct. You can make this work without the adapter plates.

Most places will tell you that a PI intake will not work on an NPI car. We all know that isn't true now. Have faith in the many who have performed this swap.

dude u guys are the best
