Pull the old one off, swap everything over to the new one, you'll have to tap the gt40 intake for the act sensor that's on the number 5 runner on your stock one, you can either do it in the same place that it was on on the stocker if there's a boss there for you to do that (intakes with egr on them i believe) or you could put it some where on the upper if there's no boss for it (non egr models) tap a hole where the vacuum lines are, your not gonna need all those lines any ways.. it takes a 9/16 bit and a 3/8 tap. Ive even heard of some guys just plugging it in and zip tie it to the fuel rail

as for all the vacuum lines, make sure everything that needs a vacuum line gets one, put the pvc valve on its one vacuum line so oil doesn't get in other lines and i think you want the fpr on its own as well, not positive on that, then just plug the rest of the lines that aren't being used

20 ft lbs. tighten from the inside out.

I just did this by myself a month or so ago (Edelbrock Performer, but same process).

Take lots and lots of pictures. Remind yourself every few minutes to stop and take the damn picture! (It's way too easy to get going and forget) You will be very thankful you did. It isn't tough, but you are pulling a bunch of crap off and it's nice to know where it all goes back.

Also, buy some o-rings for the injectors. No sense in not replacing them while you are there. It's cheap and easy - lubed them with any light (or engine) oil first.

Make sure you have coolant (it has to be drained obviously), anti-seize (if desired on some choice bolts), gaskets, gasket maker (Black or Grey), Gaskicinch (sp?) for the gaskets and hopefully a friend and some beer.

I did it alone and I don't drink, so it was a lot tougher! lol

Good luck dude, just take your time. It's easy once you finish and you'll look back thinking so as well.

+1^^^

Drain the coolant down.. so that when you remove the old intake, it keeps the coolant from running down into the engine..... take lots of pictures, lable ever conector and vacuum line, and put a new thermostat in while your there. And try not to break the tabs on the electrical conectors

furreal302 · February 3rd, 2012, 06:43 PM

Yeah those wires are always crispy and you will no doubt crack some of the protective loom over it. I've had problems with the front most bolts on the lower intake those like to rust and seize. So if you encounter any resistance, take your time with it. Loosen it a little bit then tighten it back down gently work the bolt out. It's a lot better than having to drill/tap a bolt hole that sits at a 45 degree angle.

ReefBlue1994 · February 3rd, 2012, 08:07 PM

That sounds like so much work!haha.its quite intimidating!

When it comes to working on the engine it self, the intake is about the easiest thing you can do

ReefBlue1994 · February 3rd, 2012, 08:24 PM

I realize that but this is my first internal operation!

Make sure you get the mating surfaces on the head to intake spot less!! intake was first time i cracked into an engine and i was like ohhh it dont need to be perfectly clean, well i started it up and she just blew white smoke

so take your time and do it right

ReefBlue1994 · February 3rd, 2012, 08:40 PM

I went ahead and RTVED' the head to intake gasket on,after cleaning it up,I rtved the gasket to the lower intake,and I RTVED the blue squishy gaskets to the lower intake as well,has anyone else done this?

brandon444 · February 3rd, 2012, 08:42 PM

i rtved the lower intake/lifter valey as well, thats the reason it took off the intake in the first place

but for i used gaskets from napa for where the intake sits on the heads

furreal302 · February 3rd, 2012, 08:50 PM

The only RTV I used on the intake was where the rubber lifter valley gasket met the intake gaskets. Just a dab on those corners, less is more with RTV.

ryanw · February 3rd, 2012, 08:54 PM

Oh..... are you doing the intake swap as we speak ? Wow, you dont waste any time

ReefBlue1994 · February 3rd, 2012, 08:56 PM

No im just prepping.not sure when I'll get around to the task,trying to do as
Much prep as possible,my car is running so good right now I don't want to tear it apart.
