I would be leary about just swapping out a TB from another type of car. You might be able to do it if you get the little gizmo that allows you to tweak the MAF sensor to accomidate the higher flow. Otherwise you will have idle and running issues due to the fact that the amount of air the car sees and is actually getting are diffferent resulting in wrong mixtures of air/fuel.

ok, first of all, for the late model bonnevilles, ZZP sells a LS1 conversion kit to take it up to 75.5mm. but you need to use the mini afc maf calibrator they sell to use it. i have a 92 ssei. i have a 95 SC on it. the opening on the sc is 74mm. i tried a 95 Tb before and it ran like crap. too much unmetered air . so i went back to my stock TB. well , after talking to a fellow racer at the track with a 13.44 sec 98 regal GS, he showed me the LS1 conversion and it had the mini afc on it .so i got another 95 TB , (92-93 TB is 58mm, 94-95 TB is 70mm) and recalibrated my MAF with the mini afc to show 128%, and WOOOOOOWWWWWWW. what a difference., the only hold back on doing this to a 92-93 is that the inlet for the SC is only like 58-60mm, so unless you go to a 94-95 sc, there will be very little or no gain in going to a larger TB because the Sc inlet will restrict it.
