When to upgrade to FAST??

I'm still trying to learn all this LS1 stuff. I'm old school small block/big block guy.
I have a stock internal LS1 with a nice turbo cam, GT42 turbo, port/polished TB, bigger injectors but am still searching for an intake. Had a LS6 intake but the front TB mount snapped off in a wreck.
Should I bite the bullet and get the FAST now? I kNnow..go ahead and do it.
If I do, will a stock TB work OK on the FAST......or....do the FAST 90/90? ..ugh!!

I did it when I could afford it and it was by far a great choice IMHO.

It's about a $700 upgrade compared to what I would/have spent on LS6 intake and good TB. I hate decisions. I know I'll do it sooner or later anyway...hmmm

I think that you can find a good 90/90 setup for right at 1000$ used.
