I didn't get mine today. Probably held up by the weather.

Can u use the ls1 steam tubes or am I going to have to change it?

Hmm, I'll have to look at mine again, but it seemed like the rails were slightly wider..

Ive installed a lot of these intakes for people.....

This is for when using OEM LS2/LS3 rails only

LS1 injectors require a small spacer between the fuel rails and the manifold to raise the rail for the longer injectors. #146021-kit (rails and spacers)

LS2 injectors bolt on, nothing needed, this is what the intake was designed around.

LS3/LS7 injectors require the small spacer cups on the bottom of the injector because they are so short. #146025-kit (spacer cups only)

The FAST billet rails all have there own specific kit with proper mounting brackets for each specific length injector.

What injectors will u be using

LilJayV10

iTrader: (39)

If that's directed at me I am going to use stock LS2 injectors which are 34's. I was going to have to buy a set anyway so it works out. I will have to get a set of adapters for the plug ins.

It was.. well I sent u the adapters for the stock ls1 injectors also so if you need them, thy are in there.

Can I use the LS1 style steam tubes or do i have to get rid of them and run the LS6 style?

SweetS10V8

iTrader: (4)

You have to have LS6

How are you guys using the FAST rails hooking up your fuel solenoid for your nitrous system?

One reason I was thinking about going with the LS2 stock rail was to keep everything in the same location as my stock LS1.

The FAST rails do look nice though.

Who would I contact to find out what brackets to get to use the FAST rails and LS2 injectors? I talked to John@TSP and he said there was no such animal and I would have to make my own.

Someone out there besides me has to have done this.

SweetS10V8

John doesnt know what hes talking about. On a FAST 102mm intake for FAST billet fuel rails using LS2 injectors you use 146033-kit

I googled that and that part number is the whole kit. Do they sell just the brackets that bolt the rails down?

SweetS10V8

You would have to call FAST and ask, I just know it from installs of customers cars.

I do know that you cant use the old fuel rails though, if thats why your trying to get just the brackets. The way I was told to know if you can use your fuel rails or not is to look at the bracket mounting holes. If there are only two holes, you have to buy new rails. If your fuel rail has three holes, you can just buy the correct brackets.

I found this pic on google showing the three hole style rails.....

I will have to check. Maybe lemons12 can chime in as I got them from him.

Thanks for all the help.

LilJayV10

iTrader: (39)

I checked today. I have the three hole fuel rail, so I guess they are the newer style. I will try to get a hold of FAST next week and get the brackets.

lemons12

iTrader: (71)

Yes yours are the newer style.

What was It you wanted me to time in on?

LilJayV10

iTrader: (39)

If I had the newer/older style.

Thanks for all the good info SweetS10V8. I too have had confusing e-mails from different people at TSP.

No problem guys, want to know my secret?????

FAST puts this information out for you, most people just dont look for it(including vendors who sell their stuff)! If you goto the FAST intake manifold parts selector website, you can find everything you need. If your doing something custom, then you select based on the injector you have.

For example; If you using LS2 injectors in your Mustang with the FAST 102mm intake, select any car with an LS2 designation on the selector. Example; "Chevrolet Corvette (LS2)"

Then I selected that I wanted to use FAST Billet rails, and it gave me the part number to answer the OP.

Try it guys,
