I'll be finishing the build this winter/spring and am late to the game on this topic. I have believed I'll be ok with the Fast 92 which came on the car as I have not intended to push boost. We know how that temptation may result!
Now I am playing devil's advocate with myself about looking at what else may fit which is less likely to pop - especially as it would send debris not only through the cylinders but the turbos as well. This has me reassessing my former decision.
What might be pros and cons of the BTR intakes? Or Holley? Are any of them compatible/adaptable with the LS2 Silver Blade throttle body? Or which DBW throttle body would be the optimum choice?
My main concern it fitment. It isn't a race car and I don't want to hack the firewall. They look like they BARELY fit. Can I run the fuel line easily into the rear of the BTR fuel rails and not be rubbing/grinding on the firewall?
I have BTR equalizer in my C5 with ls2 tb. I have return lines back of both fuel rails and i have to modify abit firewall even with stock ls3 intake manifold. I am not sure did that fit if you dont have return lines end of fuel rails. Car make about near 100hp more with btr and i cant feel did i lost something in lower rpm.

Are you on factory height engine mounts? Or did you lower them at all? Looks real tight at the firewall.
And can the plenum be reversed to put the flag in front? I am really picky about not putting logos in or on the car where they can be avoided. Brian is a guy I fully respect for several reasons, but I don't want BTR dead center eye catching in the engine bay. I might grind em down and repaint the intake if I go that way.

I have PDAFT engine mounts and i think they are about factory height. It fit tight but not hitting anywhere. I am from Europe so i didnt try put flag to front, but its look symmetrial and flag can be in front.
I found install pics and video of the Trinity on a C6. The downward angle on the TB mount seems an imposition. For the C5/C6 community I am surprised someone has not fabbed and is selling an angle correction kit for the tb to be mounted straight out. While I am certain it is mounted as it is either to support the F-body community or primarily for air flow, it is not conducive to ease of install and makes things interesting for charge pipes.
Too bad about the Trinity because it does seem to be the better one to fit along the firewall lip of the two.
My interest for the car remains the area under the curve. The advertisements of these affordable metal intakes suggests 6000 to 8500 rpm and hey that's super but this is a street car first before any track weapon expectations. I have more research to do.
I did not encounter enough information while searching online which quantified the metal intake benefit beyond no kaboom. Much like comparing coilovers there are generalized comments and not enough meat. Maybe this will change in the future, and intakes are the most easily swapped pieces of any combination. For now, I looked for and jumped on the first LS6 combo I found with throttle body and grabbed it for $475. It happens to also be blended/ported so that's a double score. It being the single piece injection formed intake I have none of the concerns which were driving my to consider the metal intake vs the Fast92.
Until I can gather better info I've got a plan which works for now. I also wager that the turbos will be dictating function and that the intake will be functional within rpm band. At a baseline it is safe for now. If it does not feed the need then it allows the convenience to determine a better route later.
