You might want to tell us what car you have, and whats done to it already.

Assuming its a 2000 Pontiac I would get the FAST 92mm or FAST 102mm Throttle body and the 146021-kit fuel rail kit.

I don't want the original OP to think I'm hijacking his thread but I'm writing becasue I think I understand the question he has and I have the same ones myself.

I want to put the FAST 102mm Intake Part #146302 on my 1998 Firebird Formula and from the reading I've done, this is the info i've gathered.

To run it on an LS1 car, you need to either buy the FAST Fuel Rails or you can use LS2 fuel rails.

Question 1 - Will LS2 rails connect the same way the LS1 rails did?

Injector heights and connectors are different. I've already found that Racetronix has EV1 to EV6 adapters.

Question 2 - Am I correct in assuming the LS2 Injectors will work with the rails and adapters.

So if I buy the FAST 102mm Intake, all I need to run it on my 1998 LS1 is a set of LS2 Fuel Rails and Injectors.
Also, I've see that the 102 doesn't come with any gaskets so I'm assuming I need them from FAST as well. Before I drop $1,000, I'm hoping someone can me me out. And the OP as well if I'm interpreting his question correctly. If I'm not, I apologize again for the hijack.

You can use LS2/LS3 fuel rails, yes. But they take spacers between the intake and fuel rails to account for the LS1's longer injectors. FAST sells the fuel rails and spacers together #146021-kit. My brother just got the 146302 and the 146021-kit and told me what all came with it.

If you buy the intake and the 146021-kit, thats all youll need. If you decide buy LS2 injectors it will bolt on without spacers, but youll need the injector adaptors(see link). I asked this same question at PRI and went with LS2 fuel rails myself.

Your stock gaskets will work, but most people spend the $25ish to get a new set, sometimes they swell and dont fit back in really well.

That's exactly the info I was looking for. By the time I bought a good set of LS2 rails, injectors, and the adapters, I would have spent more than just buying the kit from FAST. Thanks for saving me some time and $. Sweet S10 by the way. Again, to the OP, sorry for the hijack but maybe it answered your original question.
