Seriously, unless you are going FI or with a larger displacement motor, I don't believe the difference in performance provided by the LSX intake manifold is worth the almost doubled expense, but that's just me.
depends on your setup really
bolt-on to mild cam only or H/C ls6 would be fine
mid-wild H/C id go with the fast 90/90 so not to starve the motor of air on the top end
FI - either would work fine as it doesnt have to pull air through its pushed through
with the smaller setups its up to you if the 5-10hp is worth the extra cash for the fast setup

The guy that recently notched my pistons told me he dyoed a stock cube heavily modded LS1 and the FAST 90/90 only picked up 3RWHP over the LS6 intake. He did say that a big cube engine would definitely benefit.

ive been contemplating this too. Think im gonna stick w/ the LS6/ stock ported tb till i get heads, forged bottom, and run a bigger shot o giggle juice & then add the 90/90. Which TB is better though, the fast 90 or Nicks 90tb?

I just installed a 78 FAST intake and TB on a friends car. Replaced the LS6. It is a mild cam and most bolt ons in an A4 car. His the SOP difference was minimal. He has not dyno'd it since though.
