Default LQ4 to L92 intake

Swapping from cathedral port heads to square port heads and need to use a L92 intake manifold-

Questions are:
How to make the fuel rails work using truck injectors (l92 is returnless, mine is a 02 and has return style fuel rail)

Who sells a throttle body for that intake that is cable driven instead of fly by wire?

Anything else that would make that intake swap easier? Im thinking the hardest parts of that is the different fuel rails (maybe?) and throttle body/cable mounting.

I did the swap on mine, but I was already returnless
You can reuse your current injectors
the MAP is moved from the back to the front, just open up the harness, and there's PLENTY of extra wiring in there, no splicing is needed.

FAST, Nick Williams, BBK make cable 90mm TBs

****!

Is the IAC still integrated into that throttle body?

I keep finding 100mm TB's that are 4 bolt cable driven. They do make 90's right?

Edelbrock makes a 90mm dbc also. I know they come with or without the iac. Not sure about the others.
