I am looking into getting a LS1 Throttlebody and wanted to know what modifications besides a throttlebody adapter and MAF sensor will be needed to run it. (understand some extra tuning will be required using an AFC, especially if the MAF is not used.)
Remove the linkage, grind off the factory weld, rotate 90* and re-weld
Grind out a slit for the IAC and EVAP inlets
Epoxy in the front of the EVAP inlet so it is sealed in vacuum
Rotate the EVAP tube so it doesnt hit the SC
Grind down the lip before the throttle plate (not necessary, but ZZP does, and its wise to get the max possible performance)
Remove lower coolant lines
Get TPS and MAF adapters, LS6 MAF sensor, and Mini-AFC (2.0 is best)
Somehow relocate the PCV inlet, Breather is the easiest way, but i myself chose to drill the valve cover, add a rubber grommet and plastic elbow, and a rubber hose to a small hidden foam filter, very clean look.
Piece together solutions for connecting your air intake, MAF and TB, i was able to use the same thrasher airbox with no extra connectors, or rubber bellows fittings, and only had to slightly open the hole in the airbox for the intake tube.
Thats all i can think of right now, i did the same thing your attempting, put the entire kit together myself, so if you have any questions email me, i'd be glad to help any way i can
