Qfly. Check out the Dorman LS2 intake replacement part number 615-901, it looks like a Fast 92 but is less than half the price of a Fast 92. It seems promising but there aren't any results yet. Might be something to keep in mind for $332 or so...
I think you have to use LS2 fuel rails and injectors with the Dorman LS2 intake.
No ,you can use LS1 rails , it has the same mount points as the Dorman LS6 . The LS2D has brackets to adapt the LS2/3 rails to work in the LS2 application.
I tried to use an adapter plate with the NW TB and things did not work out so well. I could not get enough throttle cable length to get the motor below 1500 or so rpm.
So, I said the heck with it and put the stock TB back on.
On the positive side, my throttle response appears to be a little better after adjusting the throttle cable length to take up the small amount of slack that was present

I actually had the Fast 92 intake but not for long. The Fast intake I purchased came ported and the porting job was farked up so I sent it back for a refund.
They make a few adapter plates out there, quick google search should suffice. Probably pick up throttle response and a few ponies.
I actually have an adapter plate for the 92mm tb. However, I need a throttle cable adapter due to insufficient cable length when coupled with the adapter plate.
