Can I replace the 3 cylinder engine of Tata Tiago with some 4 cylinder engine of car like Indica?

In my opinion you can, but it is a complex and expensive task with requires modifications in transmission gears, engine and transmission mounts, new ECM and TCM, new wire harness etc. and these modifications might not work very well with the system already on the vehicle such as ESP, EBD, TCS, ABS etc. The exhaust would be different and will have to be as per new engine functioning. You might need to do cutting and welding to mount the new engine. Fuel pump, alternator, water pump, radiator etc. might need replacement as well. So, finally I advise you to purchase some 4 cylinder car instead of buying a 3 cylinder car and going through all these complex procedure as even if somehow you manage to fit a 4 cylinder engine in a 3 cylinder car, it would not be as good and refine as the car coming already with 4 cylinder engine.
