Alright the shaker style intake is very simple. The key piece that I was having trouble finding was the scoop itself. I took some measurments of the decklid area on my 85SE and came up with a usable area of approx. 23"x19". This limits the options a bit especially since you are going to have to use the scoop to completely center the shaker in the decklid. Most hood scoops are longer then they are wide. This makes them hard to use for this purpose or in a fiero at all. Not to mention the fact that I need a bolt on scoop. I will explain why later. After much searching and a few good options I came accross this one...
http://www.fiberglass-hoods.com/hood-scoops.shtmlFits the bill perfectly. 21.5x18.5x2 and it bolts on. Price is decent also at 110 shipped.
There are others that will work for this situation but not many. If you want an replica Trans Am shaker scoop (~125 shipped) there is one that will work at JCWhtiney.com.
This one will make it very easy to install the needed seal around the outside of it. The seal can be picked up at many sources around the net including E-bay. But its not bolt on which means you will need to make a way to attach it. It will have to be removable so keep this in mind.
There is also a hood scoop for a jeep that will work great. This one is quite a bit more expensive at ~275 shipped. I believe this is the one that Rockcrawl used in his install. Again its not bolt on.
You will have to make a seal for it. This is easy and I will go into it later. I think it probably looks the best out of the three but I'm not willing to spend that much on just the scoop that doesn't bolt on.
Now for the aircleaner assembly itself. This took me a little bit to find exactly what I needed. I'll save you all the trouble of having to look yourself and just tell you what I found. But first a little background. I took some measurments of the 4.9 throttle body and found that it is 5 1/8 inches around. This is a standard size which means that any aftermarket aircleaner assembly will fit. I dont literally mean that any one will work because there are other things to take into consideration.
First off the 4.9 is not centered when installed into a fiero. This means we need a way to offset the aircleaner to give it a more centered look in the car.
Second, the alternator sits very close to the throttle body on one side. Same thing, we need an offset aircleaner to correct for this.
Lucky for us there is a cheap bolt on solution for this problem. Come to find out that Moroso and several other companies make offset aftermarket aircleaners for cars with HEI ignitions. The offset aircleaners are only available in a 14" diameter. Not only that but they are cheap as can be. The lower hole is offset 1.5" to clear the larger size distributor. Be aware though, there are two different versions out there. One will lower the airfilter to below the tb. Avoid this one. It will not work as well for this install. The one we want will raise the filter height to 1.5 above the tb. The bottom we want looks like this...
You can buy the bottom, filter, and top seperately if you want to create your own unique assembly. You can also buy them as a complete set if you want to save some money. So far, the best price I've found is on e-bay. Its just a generic offset/raised aircleaner and shouldn't cost more then 30 shipped. I've seen them for as little as 20. The moroso version is a little more at about 75 shipped. Deffinately better quality but its just an aircleaner. It holds the filter and thats it. The cheap one will work just as well for this purpose.
I you prefer to go the pieced out route you can find the parts at Summitracing.com and many other places. They only have one bottom that will work so make sure you pick up the raised, offset version. For the filter you have tons of options but keep in mind you are limited by height of your scoop. The scoop I chose will require that I find a 2" tall round filter. The bolt on scoop can be spaced to make room for a bigger filter if you want/need one. Try to figure out the needed airflow to avoid high RPM problems.
Tb risers may be needed depending on your install. These are cheap (~15 shipped) unless you go with a billet one (~40 shipped) and can be found in sizes ranging from .5"-2.5" heights.
Now for the actual install part. I will explain the bolt on one but you will have to figue out the others.
First off the Moore bolt on scoop will need 4 holes drilled into the decklid to attach it. I would suggest that you remove the decklid for this work. Center and allign it to the decklid and drill the needed holes. With the scoop bolted in place trace the outside of the scoop onto the decklid. Now remove the scoop and cut carefully along the line you just traced. Be very carefully not to damage either piece of the decklid you will need both. Once cut out, smooth and sand all the edges til they are to your liking. The piece you cut out will end up being the bottom of the shaker assembly. You will need to cut one more hole approx 5 1/8 into it for the aircleaner to go down to the tb. Placement of this hole will depend on your setup.
Thats it for the shaker asembly itself. Now all that you have to worry about is the seal. This can be anything but keep in mind that it will be seen when the decklid is open so you may want to make it look good.
My plan is to use some sheet metal and make a spacer to go in between the scoop and decklid piece it bolts to. I figure .25 should be fine. The metal will need to be wider then the scoop to give you a lip to put the seal on. The metal only needs to go from the inside of the scoop to about 1" outside the scoop. Measure for the space you have and adjust as necissary. I would say 4 pieces to go around the outside. I can't give you measurments since it will probably be unique to each car or install for the most part. You man even figure out a different method for this. I think I will use a Fiero sunroof whether strip and the tracks that they sit in. I may rivet the track to the pieces of sheet metal and install the seal that way.
Now you can bolt it all together. I am going to put a couple screws through the aircleaner bottom to attach it to the decklid piece. The whole assembly will get attached to the tb with either the provided center stud, caddy center stud, or a custom piece depending on your install. You will probably need to make some kind of support bracket for the back and/or side of it. You also moay want to figur out a drain of some kind for the little water that will run down the scoop. I would just drill a hole in the back and add a drain tube and route it to a safe place to drain. Once mounted you can paint/decal and re-attach the scoop. Now you have a shaker style intake for you 4.9 or for that matter any carbed engine also. Make sure that you dril a hole for the PCV tube to go to. This can be put anywhere along the tube to the tb. Its really that simple.
Just so you know. If you don't care about it being centered in the decklid you can use a smaller aircleaner and scoop and put something tegether for around 50 bucks. Even being offcenter it will not look bad. You can get cheap scoops on e-bay for around 20 bucks shipped and cheap aircleaners for about the same.
I know this is not a flapper style shaker but it will allow me to get rid of the stock aircleaner assembly and use the stock side intake as a place to mount my oil cooler. It should also allow more air into the engine while keeping the cost low. Since I am moving the battery up to the front I will have nothing on either side of the engine. This means that the factory engine vents will do their job more effeciantly also and there is no need for an added decklid vent.
If you have any questions or comments please let me know. I would love to get some feedback on this. If you have other ideas or think of something I am missing I would love to hear about it. Enjoy
