FAST 102 questions
I am looking at getting the FAST 102mm and I have a few questions. First, are there any fitment problems? Second, is there anything additional I need bedsides the intake and fuel rails? Like do all of the gaskets come with it? I already have a 101mm TB. I am just trying to make sure I have everything this time around before I get started.

I have one on mine. The fitment is not as bad as everyone says it is. If you have taken an intake off of a fbody before then it shouldn't be difficult at all. Its just tight when you gotta torque stuff down in the back and be careful when you slide it in with the map sensor on the back.
You'll need the intake runner gaskets but if yours aren't old you can try to reuse them if you dont mind taking the intake off again if its leaking. You will also need fuel rail spacers.

Yes there is grinding I completely forgot about that. You have to grind part of the top of the water pump and you need ls6 style coolant crossover lines. I have had mine like a year so I forgot some of the stuff. It comes with bigger O rings for the injectors so it shouldnt leak out of the rails.

I didn't have to grind anything with mine, but I have a Meziere Electric Water Pump.
Watch the MAP Sensor when installing the intake, because it will contact the firewall and snap it in half. I rotated mine 90* so it points upward.

If you have a mesmerize you shouldn't have to. The stock one you need to to clear in intake. I tried to get a pic of mine but you can't really see it. Its not to much grinding and if you have the right tools it won't take long to do

So I got my FAST 102 in and I was wondering if any aftermarket fuel rail should fit or will only FASTs fit correctly? I have a aftermarket fuel rail kit from PP already.

I have the same kit.
You'll have to drill two holes (one on each rail) since the mounts on the FAST102 are different than the LS1/6 intakes and FAST90/92s. I used a drill press and a regular drill bit.
You'll also need larger o-rings for the bottom of the injector. You also can only use the skinny style injectors.

Why can you only use the skinny injectors?

They sit deeper in the injector holes, and the fatties won't seat all the way in because they hit the plastic. I'm sure you can do some trimming on the plastic, but I'm not comfortable cutting up my $800 intake.

Alright so do I need different injectors to make it fit? I have the stock injectors right now. How do I know if they are the skinny ones (injectors in general not just stock ones)? If I am going to drill holes in my fuel rails I might paint it since red doesn't go with my color scheme. Trying to decide whether to buy one of fast's fuel rails or keep mine, as I am going to sell the intake that came with the Fuel Rails.

Nevermind, I found it it's 3/8" drill bit. If I kept reading I would have seen it the first time.

I had to lower the k member 1 3/4" so I didn't have to cut the firewall. I think this is because I have solid motor mounts.
