Default FAST intake and TB...

I want to buy a FAST 90mm intake and NW 90mm TB or I believe I can just buy the 78mm FAST intake and keep my stock TB.Is it worth it to go ahead and move up to the 90mm equipment?How much gain can I expect?

90mm is the way to go over the stock ls6 intake you already have.
Don't buy the FAST 90mm TB, it's a total POS in terms of reliability.

I look at it this way i'e rather grow into the 90/90 than have to swap parts again.

According to this test:

https://ls1tech.com/forums/generation-iii-external-engine/132102-dyno-test-stock-ls6-tpis-ls6-fast.html

The LS6 looks better than the Fast under the curve....or more likely I am missing something?
