sell the fast, use a stock ls3 intake with the ls3 heads, use the money from the fast for the CUSTOM CAM to match your setup? I cant see any benefit to a fast intake on a turbo, seems like you would net more with the right cam.

i have these Fast 102/102 already but i am scared about the turbo spooling, I will run 11-14psi on that 408ci with 9.4cr
that cam was customized with my old setup it was 402ci with 243 heads, LS6 intake from tick preformance, so i will let them do another cam soon to my new setup
now do I have remove that LS3 heads with fast 102/102 and fix 317's and LS6 intake?

worried about the turbo spooling? you mean hard to get it to spool with the fast, or blowing up the fast with boost? Im very new to turbos, I dont know how much boost you can put to a fast intake, and I dont know how to spec out a turbo combo, however, if I had your parts, id take all the highest flowing equipment, put it on, and have a cam spec'd. assuming they are all unported heads, that would be the LS3 heads, the fast intake and TB

my turbo specs is T4 S480 with 80mm cold side, 92mm hot side with 1.1 A/R
is it small to choke?? i will use it as DD car and the street races with my T-56 tranny and i want to gain around 750+rwtq @ 13psi
soo which of these will match my setup?

I had a buddy with a ls1 383 with ls6 intake and 317's with a s480 with 1.32 96mm wheel and a brute speed blower cam 232/240 and m6 with 3.25 gear....in 4th gear @2100rpm it would make 1psi and full spool @ 2800 15psi. Your setup will spool faster then that with the smaller hotside and bigger cube.
If you already have the turbo, roll with it. You could always swap on a t6, but at 750 hp I think you will be fine. Much over that and the t6 would be a good option. The nice part is they offer a 1.10 t6 for the 92mm turbine. Have you thought about maybe 317s with an another intake like the edelbrock or the hi-ram? 317s have been over 1000 hp in stock form. I think they would be fine and can be had pretty cheap.

From what I was told and read while looking into LSA heads, cams are designed on head flow characteristic and ls3 (square port) heads require a different cam profile completely.

the vote results is 7 for 317 heads + stock LS6 and others 12 accept for LS3 heads
so i will keep the LS3 heads but which intake and throttle do you prefer guys?
I have now already 46mm precision wastegate, do i have to swap it to 66mm?

i have a set of ported 317's on a 390ci with bigger valves lookin to make 1000rwhp... if your not spending $3k+ on heads and your not matching your setup based on flow numbers....Especially under 1000hp, any of them will work.. I personally would run the cheapest route and put the money else where. LS6 intake+317's. Mighty Mouse ran 8's on a stock intake/TB...
I got my heads from AES, they ported/polished them, then flowed them, then made a custom cam for my setup. I dont think the gains from a FAST+LS3 over the ls6+317's will be substantial. Put the money into the fuel system. the 44mm wastegate should be plenty.
