Help with fuel rail / injector selection for a FAST 102 So I'm about to purchase a FAST 102 and throttle body.
I'm also going to upgrade my fuel system to include the fuel rails by purchasing this kit from Racetronix:

And these injectors:
http://www.ws6project.com/user_stor/catalog/racetronix-FI114961/
Will all of these parts work together? Ive read articles that say no... you need ls2 injectors, or an ls2 fuel rail, or a combination of the two, and/or different o-rings, etc etc. I'm just confused as hell at this point and if these parts do NOT work together as in, the fuel rail sits too high and hits the cowl or some crazy ****, can you please give me the recipe of parts that WILL work?
Note: I'm not buying anything other than a FAST 102 and I want the racetronix fuel line kit that I copied the link to. Im open to different brands/styles of injectors, but I'd like to have around 60# for a h/c/i with plans to supercharge in the future.

Those look like ls1 length injectors. As long as the mounting tabs for the rails are on an ls2/3 spacing, you should either be able to put it all together or would need to put a spacer under each of the 4 hold down tabs for the fuel rails. No guarantee on o-rings, make sure you have the proper upper and lower orings on those injectors.

Thanks for the replies! And good to know.. I'll probably go with those fast injectors. Is there a special harness or anything else I need to buy with the ls2 injectors to make them work?

Don't use FAST injectors....ever.....
FWIW,
I used the Racetronix fuel rails(very nice BTW), FAST 102 and ID 1000's(stock LS1 length)and had to make my own hold down brackets.
The brackets that came with the Racetronix rails worked fine on the stock intake but wouldn't work on the FAST 102.
