You can buy an adapter for Ls2 to Ls1 TB. That should get you on the right way. i don't dear to post a link to the product, but you find your product if you search for it.

I was just looking at my fast 92 intake.It has a hole center/top of the intake opening.take a ls1 TB and see if the TB bolt holes line up with the bolt holes of a fast 90/92 intake.

has any body taped the rear coolant passage on the head and run coolant lines over the intake when running a fast intake?

Your pic is probably a fast 78 mm. The 78mm would match a ls1 tb

Nope it says 92mm on the intake in that pic. I've always noticed the hole center/top on the FAST 90's & 92's and wondered what they were for but I don't think they are designed for LS1 style 3 bolt TB's.

It cant work, the bottom two holes on the 3 and 4 bolt have different spacing.

The fast 90/92 definately has 5 holes (i only use 4, cause only 4 are tapped), but they are not the same pattern as the stock throttle body. The top hole would require a jam nut on the back side.

You'll have to run a 4 bolt tb or buy a adapter that isn't terribly cheap. We're putting together a PTM TB & Fast intake combo special right now. If you need a PTM tb give us a call, I'll get you a great price on one!
