50$ cheaper.

If you have the LS1 throttle body, you don't need a new one when using an LS6 manifold. They both are 75mm.

Only get the 90/90 if you plan on a stroker/all bore motor down the road.

Peace,
Craig.

You can get a good LS6 intake for about 300$ off the for sale section on here all day long. Don't get a new one unless you have to.

A FAST is better, dyno proven. It all depends on your budget and power expectations.

it all depends on your future plans, for most the fast 90/90 is overkill

go FAST, i gained 35rwhp/10rwtq over the Ls6 i had on my car...it was worth selling the Ls6 intake and then spending only $650 out of pocket for the FAST 90/90...that's a little over $18/1rwhp. the Ls6 left me very disappointed. i should have gone FAST 90/90 first time around. i learned the hard way...

Agreed. And I would suggest our 90mm billet TB. Known for not having the issues of sticking blades, etc. some have.

go with the fast 90 if you have bigger mods like a cam or nitrous, LS6 is fine for stock engines IMO

a 'dyno proven performance' book published by SA Design showed the LS6 performing well in F/I setups

i work @ a dyno shop and we didnt notice any gains with fast 90/90's over ls6's with the 3 cars we tested. i would say stick with an ls6. im running an ls6 with 680rwhp but in my case its fi. i havent tried a fast on my car but i hear they dont do much for fi cars...
