Modified FAST install




1. Would you happen to have a pic of the FAST with the cut before you glued it? I;m trying to judge how much to cut off.
2. Where did you get the plastic patch piece & what is it?
3 Which Goop product did you use?
4. When you say mildly port - could you be more specific where? Did you open it up, put the lower part on the car, mark runners where they meet the head and clean up any areas that don't seem to match up perfectly, or did you just open it up and clean up some casting flash?
5. Can you reseal the FAST with the existing manifold or do you need so use some sealer (what type) on it?
And will you hold my hand while I do it?
Just kidding, but figured I'd ask these detailed questions so I can get the supplies that are proven to work. Thanks much guys!! Great post, this is what the Forum is all about. 
just send it to me when you get it. I will be back in NY this Saturday.
The sand/smooth/paint runs 299.00... They are sanded smooth(Entire intake) etch primed, sanded again, etch primed again, finish sanded and then painted your choice of color with base/clear paint.
As far as holding up, the intakes are just like the exterior of your car. No worries about gas/oil or heat.
I have not priced out the modifications for the C6 customers yet as we have only done a few of these in house.

Looks kind of simple.. probably a DIY, but if they charge $50/$100, it may sway me to just have it done. The $899 price is only ported, no mod to the rear to gain the firewall clearance.
The Best of Corvette for Corvette Enthusiasts




There is so much bad info on this product I am surprised at this point having done 100% of the work for someone and posting pictures that there are still people thinking the FAST is a 1200 dollar project. It cost Cameron 55-60 bucks total to get this thing working on his car.
1-There is no (zero, nada, nothing) needed other than 12 cents in washers from home depot to get the fuel rail to fit with this manifold. The mounting holes for the screws are off by about 1/4 inch so 1/2 inch washers hold it down. 79 bucks for a kit to do what I did for 12 cents is azz rape. I did it this way so many times and was told to do this by A&A corvettes years ago. It works fine. If it bothers you that much buy a LS1 fuel rail used for 50 bucks.
2- PORT WORK: Having the FAST ported is not an apples to apples comparison. A true port job as performed by Tony Mamo is a custom intake runner match to a specific head and cannot be done generically to a FAST manifold being used with other than stock heads. The opening to the intake runner is smaller on the stock heads than the AFR's, ETP's, trick flows...ect. Carteks heads have a trapezoidal opening and wont work with any other than a custom or stock fast. Smoothing out the runners as I do with a dollar worth of sandpaper and get consistent results now with 12 separate FAST manifolds speaks for itself. You cant get a generic port for a specific head unless its the stock head that it is port matched to. Port matching is the real gainer in porting the fast manifold. The FAST is already port matched to stock heads fairly well out of the box.
3- $89 to cut the back of the manifold an have it fit without cutting the firewall is a good deal so if any vendor is offering it that low, my objective in debunking the cost of this mod has been met.
Comparing this mod to a L92/L76 head swap which I have also done, is a clear indication that the person suggesting it has done neither of these mods to his car. I have done the swap to my car and it was far from 1200 bucks. The L92's dont work with the stock springs and retainers, nor do they fit without notching pistons with cams beyond 224 xer lobes and optimum compression. To date my L92 set-up with a 228/232 cam is already well north of 2200 after 450 for springs, renting a flycut set-up, and a retune. Giving people a parts list of L92 parts with springs that cant handle a 204 cam to 6k rpms is as silly as suggesting it is a DIY project as I have tried to help other to do with the FAST at 800 bucks installed by themselves. If you can handle a head swap yourself then the FAST is a 775 dollar mod to you. If you cant do the FAST install yourself for this price then suggesting heads at 1200 bucks is even more silly. 15 hours labor in this market isnt cheap. Locals by me can simply ask me and the heads will be installed for the cost of a nice dinner.

Its a DIY thread not a place to compare tuner pricing. I tried for so long to make a real DIY tech thread and it degrades into packages......
If Dave at Cartek posted this, people would be pissed if another tuner came on here offering th same service. It should be in another thread.
we got one of the best tomato pies in the state Columbus farmers market
First, you said you just need washers for the fuel rail, didn't you say you need LS1 orings as well?
Second, we keep hearing about this elusive plastic piece that was gooped on, where do we get this piece?
Would be very helpful if you could post a list of all the parts involved and where to pick them up.




This stuff is not rocket science
Spins write up, provided all the information necessary to make the installation a real easy DIY. Now if you are "dangerous with tools" he even offers to do the work for a donation to St. Judes Childrens Hospital and a nice meal.

The rest of your questions are why the thread was created.....for you to ask and for me to answer. sourced the lastic from a 5 dollar radio shack plastic box intended for making electronic projects. They come in black or blue and serve as the source for a right angle peice of plastic that has similar thickness and strength as the original plastic peices. You could use any similar source for plastic. LG used sheet metal. The glue (called GOOP and sourced from home depot) will bond nearly any two materials together permanently. The purple tube is for plasic and metal. I have used the orange type for building speaker boxes and bonding wood to plumbers PVC pipe as a tuning port. I can lift the 80 pound box from the tube. It is strong. I made my home made K&N filter assembly 3 years ago with the stuff in the purple tube and it never came apart n 3 years.....nuff said bout dat.
You are being too rigid in thinking these parts are set in stone. I wanted to show that it could be done cheaply and how one could go about doing it. LG did a similar mod but they used a different glue and sheet metal rather than plastic.
As for the o-rings, the FAST is a manifold intended originally for use with an LS1 or LS6 engine. The LS2 came out after they did and the LS2 uses thicker o-rings on the fuel injectors. For the manifold to work you need to use the LS1 o-rings and that is a matter of calling ny vendor for them. Shop around, they are 25 bucks or so. I have seen double that from forum vendors. Get them from Fred Beans.
The paint I used again (yes I did paint them before) was VHT epoxy paint and stands up to anything in a car environment. I also used it on my shifter **** that I transferred from my 2001 C5 and it is as high gloss and perfect as it was when I sprayed it 5-6 years ago and that is touched every shift for all these years on 2 cars. It s 7 times harder than regular spray paint. It doesn't have a scratch on it and never wore off. It is also self priming and that is a big help.
So cut with a dremel and the glue fills in imperfections in the cut if you arent an artist. Mine was pretty much perfect because I'm spin. If you need more help this thread is here and I hope you dont have to dig through 500 nonsense posts about what other vendors offer as an option to this project as a DIY adventure. By the way I didn't think vengeance was doing anything wrong offering a base piece that was already painted (nicely at that) and ready for you to cut up. I dont like the use of my thread for advertising or offering this DIY project as a service. That should be contained in a new thread.
If anyone messes up, I can/will fix anything you did to the FAST. There is nothing that cant be reversed even a huge crack or a horrendous over sized cut. I can fix anything like that.....yes for free
