Default Intake Manifold suggestions?

Looking for some feedback on what it takes to throw a 90/90mm ls2 intake on?
Or
Is it better to stick with a LS6 intake?(80/80)
I'v already located a t/b that will work for the ls2 that uses a throttle cable instead of drive by wire..
My main consern is,
ls6 a better intake over the ls2 intake, or is the ls2 a better op then spending the big bux on a FAST 90/90
Also will fuel rails, injectors, ect work on the ls2 like they do for a ls6
HEADS = 243(ls6)

Go LS6 if you are just looking to keep your car a bolt on.

Go FAST 90 if you have the money and atleast have a cam etc...although people do go the 90 route with bolt ons.

The LS2's flow is pretty shitty last I remember.

Like lithium said an LS6 intake outflows an LS2 and it takes alot more to make the LS2 manifold work (I believe the fuel rails don't bolt right up.) If your looking to go with a H/C setup a fast 90/90 setup may be a good investment.

But if its a bolton car a LS6 intake and ported stock throttle body will work great

i used the weiand. its an alumionum version of the ls6.it has an acces panel on the bottom for porting.and the opening can be ported to match the 60mm t/b.it looks good and resonably priced
