Ported Manifold Swap DIY.

[FordFasteRR]

Instructions for removing & installing the Intake Manifold

TOOLS:
Basic mechanic socket set.
Jack, 2 Jackstands.

Time: 2 hours.

Before you begin: Be sure to disconnect the battery. Have a few bottles of water to drink or some beer...

#1. Remove the air intake pipes & associated vacume lines.
#2. Remove the injector harness from the injectors.
#3. Remove the map sensor harness.
#4. Remove the Idle air bypass valve harness & the TPS sensor harness.
#5. Remove the pcv hoses (there are 2 of them on the back of the valve cover,
One goes directly to the intake manifold next to the map sensor,
the other went to the intake pipe.
#6. Remove the throttle linkage cable & cruise control linkage cable* (*if applcable)
Set them aside and out of the way.
#7. Remove the 4 nuts holding the TB in place, pull the TB & Gasket off and set it aside.
#8. Remove the Brake Booster Vacume Hose & both of the TB coolant hoses.
( This would be a good time to do the TB Coolant bypass mod, just re-route one hose
back to the return nipple ! )
#9. Un-screw the fuel tank vapor valve bracket, & remove vacume line
(you will find this valve just below the brake booster hose).
Leave it dangling there, do not remove its harness.
#10. Remove the 2 bolts holding the fuel rail in place.
#11. Carefully pull the fuel rail out of the manifold, set it aside (on the drivers side).
If you want, you can wrap it in a towel to keep the injectors from getting dirty,
& keep an eye on the black o-rings, you dont want to lose them !
#12. Remove the firewall ground wire from the back of the manifold.
#13. Remove the wire-harness clip that is just below the ground wire, It holds a wire loom
to the manifold, you will need to zip tie this back on later if you break the clip.
#14. Jack up the car, insert jack-stands using all known safety measures & procedures.
#15. Get under the car and remove the 2 LOWER bolts holding the black steel manifold brackets.
#16. Reach up and try your best to remove the top 2 bolts holding the steel brackets.
(this is almost impossible to do because of the small space, but I managed to get 1
of them off when I did this mod, but I dont recall which one... ANyway, just do it).
#17. While you are still down there, use your socket wrench extension to reach the manifold
nut that is hidden above the air conditioner compressor. (thats the only nut that is tricky)
#18. Remove the remaining lower manifold nuts.
#19. Get back on the top of the engine and remove the remaining top manifold nuts.
#20. Carefully pry the manifold free of the head, and remove it straight upwards and out of the engine bay.
Check for any remaining wires or vacume lines that may be left... remove as necessary.
#21. Remove all of the brackets and sensors from the manifold & attach them to the new Ported manifold.
#22. If your gaskets broke, install new ones, you can buy a gasket set from the dealer for $25.
It will include gaskets for the IAC valve, TB & manifold, there is no gasket for the MAP.
If you are carefull during the removal process, you can easily re-use your stock gaskets.
#23. You will not need to re-install the manifold brackets, you can discard them & save weight.
#24. Re-install EVERYTHING in the same order that you removed them.
#25. Do not over-torque the manifold bolts. just tighten them down snug and tight, but not TOO tight.
#26. I was able to re-install the manifold without getting back under the car.
You will most likely encounter trouble getting the nut between the IM & A/C compressor,
But with a little TLC you can get it on there... I've done it a bunch of times with no trouble
at all.

THE END !


If anyone finds an error or If I missed any information, please post on this thread so that I may correct the errors.

Thanks !

wow that sounds like a lot of work...im sure itd be quick, but not somethin i wanna jump up and do...lol

thanks for the DIY too!

[FordFasteRR]

its so easy.... you would sit there and laugh at me while I do it ... I can swap the manifold in 30 minutes... :)

Those instructions are there as a reference... most of it is obvious and very simple to figure out :)

[vabeach_03]

evan. its simple and i would just like to add my 3 cents.

#6 is not needed. simply unhook the cables from the brackets and leave everything hooked to the TB. when you take the TB off just swing the cables and everything out of the way. i did this twice on my car and once on guess's with no issues.

I looked online and found that EVERYTHING on this DIY is torqued at 17-23ish ft/lbs. however there is almost no room to use a torque wrench on anything.

Also, take into consideration that Ford is being extremely detailed in his DIY, which is a good thing. I think #'s 1-5 take 3 minutes alone lol... I'm surprised he didn't # the times he went for a beer or to go take a piss. The list would have been even longer lol. But seriousely, it was not hard at all. I'm 6'0 about 200 lbs and got under the car to loosen the bracket when we did my car...

sweet time 4 me 2 do it

[DAILLESTWUN]

I feel so special guys...you guys used pics of my car and it's internals..... you know I'm here for you guys whenever u need me lol... :D

[jtigki]

does the performance increase! by how much ?

[PSUsouthpaw]

Yes, swapping in ported/polished intake manifolds will definitely increase the performance, as the car will be able to draw more air in through the intake faster and more smoothly than before. I can't give you an approximate number, although somewhere on here there are dyno graphs, thanks to Ford I think, if memory serves me correctly.

It's an excellent mod to do, and though it may take some time and work, it is very worth it for the power gains and the slight increase in gas mileage. If you are going to the trouble to swap the manifolds, this is the same time to invest in a phenolic intake manifold spacer and to consider a big bore throttle body, along with the throttle body coolant bypass and installing a pcv catch can while you're at it.

^ What Jared said!!! :D

It's been said that it increases performance, and the truth is, it most certainly does. An accurate number cannot be placed on it however, because the benefit isn't in numbers.

Doing this to your car will increase your acceleration, therefore making your car faster. If you've added intake, header, and exhaust and then do the switch, you'll find a lot more power available. You'll also find there is an actual number associated with power levels. Probably somewhere in the neighborhood of 5hp. The gain seems low, but until you've had it on your car and felt the difference in acceleration, you'll know then that it was worth it.

I plan to do everything that Jared said above (I already have I/H/E). I will be porting/polishing IM, TB, adding Phenolic spacer, and upgrading from SRI to CAI.

[PSUsouthpaw]

Hehe, I think I want to do the intake part first, than spring for headers...

[wagonofhell]

i am in the middle of this one right now, did not have a man that was ported so i have to port then put it back on. i am hoping for a better average gain rather then peak. nice diy

[FordFasteRR]

the ported IM gives you a nice boost in power all across the RPM band.

=) Of course, to get the best effect, you should match it up with a ported throttle body and knife-edged butterfly valve.

i know im prob gona get flamed for bringing back this thread but i just got the ported / polished intake manifold so I will hopefully be installling it shortly

[DAILLESTWUN]

I'm sure you will be pleased...
