Intake manifold for FI I tried to search multiple times but it keeps timing out for me.
Should I stay with the stock ls1 intake or spend the $ on a LS6 or weiand?
I've heard that the FAST's like to break on FI applications.
Do i need to go with aluminum for precautionary measures or will the ls6 work just fine?
Is there enough of a gain by changing the manifold or should i just save my $ for something else?
Doing the supporting stuff before i put a D1SC on it and run 8-9lbs, someday going to try and max out the psi.
So who is running what for an intake?

right now i'm looking to hit 500 or so, but who knows after i get my first taste.
I do see it getting up to the 600-700 range. I got a ride in a 580 horse vortech supercharged lt1 camaro and that thing was amazingly fast
At what point are you guys changing to the carb style intake?

LS2's have done fairly well with FI applications too just not NA ones. It is also cheaper so you could do that and upgrade to a carb style once you really start making boost!

...so even over 10psi, I'd still run the LS6 intake. 
IBZ34's dyno thread was very interesting comparing the carb to the ls6.he had to pull alot of fuel to get back his 12:1 a/f.so it seems worth it to me to sacrifice 10-15hp to even the air flow and to get better gas mileage
