*General* FAST LSXr 102 thread
I used my buddies FTP lid just to test fit and the lid sits WAY to high for the maf sensor and with the rest of the set up.
running fast 102 intake m. / with / TSP maf with their coupling/
Called TSP and they said i would need another coupling from the lid to the maf..??
Called FTP and they say the (104mm)lid was a straight shot from the Lid to the maf..??
A local shop says You need the Lower LT1 radiator holder/were the lid sits to lower evrything down for the it..??

I ported the manifold myself and prepped it for the injectors and MAP sensor. I'm going to be using BBK red billet rails seeing as I couldn't use the LS1 rail. They were the same price as a plain-Jane new LS2 rail and I actually like them better than the FAST. The BBK also comes with a crossover line and connects to the stock fuel line so I don't have to spend another $140 on those like with the FAST rails. I hope to finish up the project tomorrow. If it doesn't rain tuning (by me) will follow.
I have no idea why FAST makes their manifolds grey but I don't like it so mine is black.

Seeing as everyone says you can't use 42# green tops with a 102 so I painted mine red! Pretty clever huh?

Just finished and took it for a very brief test drive. My fueling was off over 5% at WOT so I didn't want to bang on her too hard. There are some install notes tho.
I used the back location for the MAP sensor (instead of the front EGR point) for a cleaner install. Most of the installs I've seen use the front point which makes for a messier look IMHO plus requires extending the wires up to the front. There isn't a lot of room in the back tho and I had to slightly bend some lines to make enough room for the connector. The front point of the intake dips down lower than the LS6 intake and it hit the steam tube holding the front of the mani up. I gingerly hammered it bending it down in the right spot so the FAST would seat down all the way without hitting. Thankfully the crossover pipe isn't leaking from the abuse. The rest of the FAST install was pretty straight forward. It was the BBK fuel rails that took some modding.
I carefully read the BBK instructions and watched the video. On the underside of the rails it has stamped where to attach the mounting brackets for a LS1, LS2 or LS3. I put them in the LS1 location. They didn't really line up and after looking at it again I realized that the FAST is really a LS2 intake that you can use on the LS1. After moving the brackets to the LS2 position they lined up.
Next up was getting the brackets mounted. BBK gives you 2 thick and 2 thinner spacers that you use in combination to get the proper spacing for the bracket to manifold. The end of the bracket that mounts to the manifold is slotted to allow for adjustment for angle. The way they show you to mount the bracket on the rail was going to need both thick spacers, a thinner spacer plus a nut to make up the distance. With the longest bolts they give you there wasn't a lot of thread holding it.
The brackets come with a slight angle from straight. I put them in a vice and bent them the other way and then mounted them "upside down" which greatly lowered the distance to manifold and gave a better angle for the rail. Instead of the bracket being up high it was now close and I had to grind the end of the bracket so it cleared the mani runner that sticks up. With one thin spacer and short bolts it gave a much better angle and looked better too.
The BBK crossover hose is rubber that you push onto hose barb fittings on the end of each rail. It went on so hard that neither my son nor I could get them on all the way. I took the assembly and put it in my oven at 170* for a while to soften the rubber and then I could push them on correctly. Being at the back on the mani it looks a lot better than the braided hose crossing the front with the FAST rails.
Pics below.
The brackets were bend just as slightly the other way. This is after my bending.

Very nice setup by the way. I love the flat black.
