The easiest thing to do would be to buy a 24 fps motor for it. If you also sell the existing 25 fps motor, you could come out very close to even.

The other approach would be to work as if you were doing European TV, with picture and sound both at 25 fps/50 Hz. That can be projected at 24 fps, with a very slight slowdown. That's how European shows are presented here, no problem really.

Another thing to consider: What is the frequency of your electrical utility system there in India? If it's 50 Hz, going with 25 fps will be safer for shooting with magnetic ballast discharge lamps, neon signs, etc. If it's 60 Hz, 24 fps will have that advantage.

Sure, you can use it in projector. It will just run a little slower. Almost unnoticeable. Do test it with the 25fps motor before you buy other stuff...

In a PAL telecine: YES a little with the regular motor, you'd probably need a crystal controlled motor (i.e. Tobin, Thoma, CE)
In a 24fps projector: NO of course not: you record at 25 fps and play back slower at 24.
You could speed up the audio for a test...
Also remember that the 2C is probably the last camera to use for dialogue (noise!) unless you have one of those blimps that weigh 3 tons (boy, these are heavy - even the Cine 60 plastic one weighs a lot)
