P.I. swap ?

[Sn95Willis]

I think I have most of the stuff but not sure... I have almost complete 2000 GT motor.. it is missing the valve covers,timing cover and front accessories.. I want to swap the heads ,cams and intake over to my motor.. Now I know I have to get gaskets for the heads and intake and valve covers and a timing cover but what other parts will i need to buy? Can some some make a list of what i have left to get... Oh and the 2000 motor is still together..

 

[MustangChris]

a list of the manditories: (i may forget something, feel free to chime in anyone if i do)

heads (be sure, if you keep them stock, to have the head "decked" and the valves vacuume tested)
cams
intake manifold
valve covers (be sure to count the bolts. romeo and windsor valve covers have different number of bolts)
head gaskets
head studs
timing chain (brand new, no reusing)
and you should be pretty good.... off the top of my head...

things i personally bought in addition to this stuff:
locking headers bolts from FRPP
timing gears

and thats about all i can think of right now... i hope i helped brotha, but im sure i forgot something, but at least i got you started. lol.

the FRPP head swap kit also comes with a dipstick tube and some rubber tubes.

you can reuse the timing chain, some dont suggest it but i did it anyways and its holding up good. a few things on that list that i didnt see were:

timing cover gaskets (all three)
intake manifold gaskets
valve cover gaskets (might as well)
timing chain guides (replace them now....much easier to do than to tear down the motor again when they wear out)
water pump nipple (if its going onto a 96/97 car...98 already has it)
exhaust manifold gaskets
collector flange gasket (from the exhaust manifold to the mid pipe)
you are going to need tools to drill into the intake manifold for that extra sensor


and i think thats it, at least all i can remember

 

[MustangChris]

i wouldnt reuse the timing chain, just asking for trouble IMO when you ALREADY have the timing chains out, ya know?

hmm, i dont have a few of these parts you listed. Can you post a link to the timing chain guides, the water pump nipple, and a pic or something of the "extra sensor?" please?

well true, if you already have the chain out it doesnt hurt to replace it, and all in all prob not a bad idea. i checked mine and it looked fine, so i just reused it.


but ok, onto the pics you requested.

timing chain guides: http://drobnak.com/dave_car/pics/AlumBlock/timed.JPG
that picture is of a cobra motor, but the primary (long) chains on that motor are the exact same as ours. the guides are what the chain slides on between the two gears. one is straight, while the other is curved. these will, with time, change color depending on how worn out they are. the dark red that you see will slowly start getting lighter. since you already have everything apart, might as well replace them as preventative measure now rather than later when they break.

when you remove the intake manifold, you will notice that there is a metal pipe that goes there. that metal pipe is called the heater return tube: it routes the coolant from the heater core back to the water pump. its only held on with two bolts that go behind the drivers side head, and then it simply slides out from behind the water pump. well, where it slides into behind the pump, thats the water pump nipple. the NPI nipple is a little longer (on the left) than the PI nipple (on the right). you need to swap these out so the proper tube will fit (because the PI manifold is deeper than the NPI manifold, it requires that you use the PI tube which is routed a little differently). the nipple has to be removed by tapping it out TOWARDS the water pump....which means the water pump has to come off. its installed the same way, by tapping it in FROM the water pump towards the back of the engine. if you have a 96 or 97 model, you will need this part. if you have a 98, you WILL NOT need this part as our cars already have it.

ok, for this one you have to look at the crossover tube (in the picture, the aluminum part of the intake manifold) on your car and compare it to the one from the 02 engine. on your car, it might be a plastic crossover tube rather than an aluminum one. you will see that on your engine, you have two sensors there; one controls the gauge in the dash, the other tells the computer how hot the car is. on the 99+ models, ford deleted one of the sensors and made the gauge read off the ECU sensor. what you need to do is drill a hole (I believe its a 3/8" NPT size) for the second sensor you have. this is made easy because on the PI manifold, ford left a spot for the sensor, they just didnt drill the hole. in the picture above, the location is right behind the thermostat housing.


if you need anymore help, let us know

well inspecting is fine except the main problem with them is that they tend to strech, which is pretty un-noticable.

and as for the guides: ive only heard them refered to as tensioners. so thanks for the info. i didnt know about the color change!

and awesome! thanks for the info! what about the "crossover" for PI intakes? whats that about?

I forgot, but I believe 2000 is still a windsor motor, right? If so you need a few different things. I know it may be overlooked but you need different studs for the timing cover where they bolt into the new heads, because the threaded holes are larger on windsor heads then the romeo heads. When i did the swap with some windsor heads, I didn't need to get a new timing cover, I was able to reuse my old one and it works fine. I have heard that you need to put a new crankshaft gasket in the timing cover otherwise it will leak oil out of there. Also you are supposed to have a new crankshaft pulley bolt because those are torque-to-yield so they cannot be reused. although this isn't required I would reccomend the lokar flexible dipstick, it will make life much easier. I know there is more stuff I am forgeting but those were a few things that stuck out in my mind that weren't already covered. the best thing you could do is go over to modulardepot and talk to randy, tell him what you got and he will get you everything you need to complete the swap. he is deffinately very helpful.

 

[BrandoGT]

I was looking through my computer files and here is a list of everything i needed for my windsor PI head swap on a 96 gt, with their ford part number. this I what i needed when I had the heads, intake,valve covers and ford racing head change kit (go with this because it is a lot cheaper then getting the head, intake, and exhaust gaskets individually through ford).

F5AZ-6700-A (1) Front Cover Crank Seal
F5RZ-6A340-B Crank Bolt
2L3Z-6584-AA Gasket Valvecover
2L3Z-6584-BA Gasket Valvecover
YL3Z-9439-BA Intake Manifold Gaskets
F1AZ 6020-C (1) Front Cover Gasket
F1AZ 6020-A (1) Front Cover Gasket
F6AZ 6020-BB (1) Front Cover Gasket
YF7Z-6279-AA (2) Cam Bolt
F1AZ-6278-A (2) Washer
F1VY-8255-A Seal- Thermostat
F1VY-8507-A Gasket Water Pump
XR3Z 18B402-AA (1) Heater Tube
F8AZ-10153-EA (1) Alternator bracket
F75Z-8555-AA coolant nipple
XR3Z-9L437-BA plenum gasket
XR3Z-9450-AA header down tube gasket (wasnt required since I put LT's on)
N808140-S431 STUD (for the previously mentioned larger holes in the head)
N808142-S437 SCREW (for the previously mentioned larger holes in the head)
N808529-S309 STUD (for the previously mentioned larger holes in the head)

oh yeah and a 3/8 NPT tap for the extra coolant sensor.

 

[MustangChris]

thanks bro!

 

[Sn95Willis]

Sorry for the dumb ?'s but since I have a 2000 motor that I am getting the heads cams and intake from all I should need is the head swap kit from FORD?

Just trying to make sure I int missing any thing or find another chunk of change Ill have to spend..

 

[BrandoGT]

No big deal about the questions, When I first did my pi swap i was mainly over on modulardepot forums and i asked a bunch of questions too, there were several people that were really helpful. i think having the community helped out alot so keep asking and we will try to help.

If it has everything there on the motor, although you will at least need the other gaskets that reivaxtorres mentioned. none of that extra stuff is that expensive and more the likely some of them will get ruined when you are taking the old stuff off. also like I said the crank bolt must be replaced since they are torque-to-yield. you don't need cam bolts since if it is a windsor cam, the gears are pressed on, and if they are bolted you just dont have to remove the cam gear. I recommend doing it right and spending a little more because it will be much betterfor you in the long run.

 

[MustangChris]

+1, thats why i bought new cam gears and timing chains...

 

[Zwolaver21]

Why dont you want to put the complete 2000 motor in your car? You could just swap over the valve covers(if they are the right ones im not sure on the years),timing cover, and front accessories from the car you have now. Buy some new guides, tensioners, timing chains, and maybe a cobra oil pump and pick up while you are at it. This will keep your compression lower so when you decide to throw on a Vortec or something you will be good to go.

 

[MustangChris]

how will a oil pump keep a low compression?

or do you mean the 00 compression ratio compaired to a 96-98 with the pi swap... nvm...



if you are a pretty handy mechanic, i would do the pi swap for a high compression ratio, then when you want a blower, put in the 00 motor and the pi heads for the lower compression :-D

dono if the 96-98 computer will work with the 99-04 motor.. just saying.

 

[Zwolaver21]

My bad I was talking about the 2000 motor comp. The computer will work you just have to use the wiring harness and coil packs from your car and you will be good to go.

 

[Sn95Willis]

I think the bottom end on the 00 motor is hurt.. the hears ,cams and intake are fine.. Thats why I dont use the whole thing...

 

[MustangChris]

ah, well that explains that.

 

[BrandoGT]

yeah thats why i don't think you need the bolts and such. The head swap kit is pretty awesome. the rubber tubes were actually a good idea for putting the heads in because it lets you put the heads on with the head bolts in the head. due to clearence issues you cannot put some head bolts in while the heads are on, but yeah once again I recommend getting new gaskets and such like MustangChris has.

 

[MustangChris]

wait, what are those rubber tubes for? lol

 

[Jrgunn5150]

wait, what are those rubber tubes for? lol

Putting the head bolts in. Specifically, holding them up while you maneuver the head.
