I just received my FAST intake and have a few questions.

1) How are the three sections normally sealed? Mine looks like there is a siliconce sealant between the layers. Is this normal?

2) I did not get the any bolts with it. For the bolts that hold it to the engine, will the stock OEM ones work? For the bolts holding down the valley cover, I know the OEM ones are too high. Has anyone tried to grind the heads of these bolts down to stop them from interfering with the bottom of the FAST? This seems like a simple solution for me.

I've been reading what I can find for info on here and also had some advice from SpinMonster ....any other tips before I start the install?

 

There should be what is known as a rope gasket (one piece,probally orange or green) that surrounds a seam for the sections.I got new bolts with mine, but not sure if thats the norm, since I've only ever purchased one.

 

Miaugi,

I still am not done with mine yet but I will post what i have learned, the Lingenfelter MAP kit came today with out directions so I am not 100% sure how all those pieces come together. (correction; take a look at the sweet detailed silver devil engine midway down, save the pic and blow it up and you can see the detail for the MAP sensor http://forums.corvetteforum.com/show....php?t=1731083) My intake came assembled already, the three piece all come together like a sandwich with the gray on top and the obvious black piece on the bottom. From what i was told by a forum sponsor the corners have black RTV around the corners and other places holding the pieces together so taking them apart is not a good idea especially if purchased new. The intake is also held together with shorter allen head bolts around each end of the intake. As far as re-using hardware i was told to use the supplied replacement bolts that attach the manifold to the block. (see photo, stock seems longer???)

The button allen head bolts came with mine, so if you get them you take the intake off replace all of them except the one towards the throttle body inlet under the PVC valve, its the tube coming out of the 'valley pan' you will notice it when you take off the intake.

replace the LS2 fuel injector o-rings (orange) with LS1 (black) I have been told that they will fit the intake much better, I bought the kit from a chevy dealer in vegas for 18 bucks because it was sold as a kit and had all of the o-rings not just the bottoms.

I cant comment on the fuel rails since its not going back on yet.

Also you will need to plug one hose adapter on the rear of the intake,(to the left of the sensor hole, underside) in addition the sensor hole that needs to be plugged which is taken care of with the lingenfelter kit.

The FAST kit I bought also came with eight new manifold runner gaskets (orange) and a 90mm throttle body gasket (orange)

The instructions if supplied are not very good for our application and if you wish to order the 'harware' there are several venders who sell the intake that should be able to get the 'hardware' kit or gasket kit

Use the removal instructions from ls2portworks.com, it helped me out quite a bit. (lots of tips and photos)

I posted the pics for feedback good/bad to help out the next forum member.

Also what bout paint? thae paint I used seems tacky after a week, any brands/tips? thanks

Good Luck!Note stock vs. FAST bolt

 

Thanks for all the pics and your comments...they helped me understand things much more!

I was also thinking of painting mine black, what brand/type of paint did you use? I know there is paint made just for plastic (I think it's for poly propylene & poly ethylene) but since the intake is not this type of material I was going to use a higher heat paint in a glossy finish.

Can anyone suggest a better choice?

 

So curiosity got the better of me and I have seperated the three sections of my FAST. The build date in case it has any signifigance according to the molded in clock is 08/2005.

The orange gasket seal between the top and middle section had silicone applied at all the corners (where 3 pieces meet in a Y formation), to me this seal should not have any additional silicone, can someone please confirm one way or the other?

In between the middle and lower section there was no gasket, but around the ports also had black silicone on it, is this correct?

Thanks in advance.

 

I have no idea why you took it apart, you prolly just bought yourself some pain. They are supposed to be sealed with silicone and I don't suggest just slapping it back together and hoping it doesn't leak. These things are prone to leaking so make sure you seal it up good when you are putting ti back together.

 

Actually, the instruction sheet I got with my FAST says:
So....the instructions tell you to take it apart and then put it back together.

The little boy in me must know how it works....so I had to take it apart!

Oh, and the **** Corvette guy in me didn't like the way black silicone was oozing out in several places....now it's on it's way to being just like "new"!

 

True, the instruction did state that and it had me scratching my head until I talked with a forum member, thats why I put the comment about the instructions not being very good.

Also TTT for paint? where to buy/kind? any help?

Thanks

 

I took my FAST completely apart and cleaned/reassembled it over the weekend. With your help as well as a couple of PM's from SpinMonster eveything went well.

For paint I used Tremclad Hi-Temp gloss black, it turned out great looking and was dry in two hours. I also sanded off the Wilson but left the FAST logo.

I drilled out where the MAP relocation disk goes as that had not been done yet. I can see from the bottom of the FAST that the previous owner did not change the valley cover bolts as they marked the underside of it, but no cracks. BTW, it looks like only 8 actually touch the underside, 4 on each side.

I will start the removal of my stocker and the prep for the install of the FAST tomorrow.

So far so good.
