Hey there, I think you've misunderstood what a 90mm LS6 intake actually is! I collected the data in the flow test thread and have a couple of 90mm LS6 intakes so i know what i'm talking about

The LS6 90mm intake IS NOT a stock LS6 intake with a just a 92mm TB slapped on the front of it.
The 90mm LS6 has the stock 78 mm snout cut off of the intake manifold and replaced with a 90mm snout from an LS2 intake. LPE did the one below in 2017 and the new snout cost $350. My 91 RS has a TPIS converted 90mm LS6 that was done in 2015.
You can see where the new 90mm snout is glued and bolted on to the LS6 intake. This one was done my Lingenfelter Performance Engineering.

With porting the Fast 90/92 mm will have more potential. The LS6 runner maxs out around 275 cfm of air the fast can go 5 to 10 cfm higher with port work.
The 102 Fast will flow more air
It can also be harder for the typical tuner to get sorted out to drive well on the street. Make sure you have access to an outstanding tuner if going this route.
