Answer:
The answer is yes, you would have to buy the correct turbo kit (turbo, oil lines, turbo exhaust manifold, intercooler, piping, etc) and tuning software (DSMlink). It is a good bit of work if you are not experienced with cars and building them. To turbo a non turbo car is is important to make sure the engine can handle it and SHOULD be rebuilt properly to ensure that it will last. If you are serious about this than I suggest reading up on dsmtalk.com and dsmtuners.com both are forums about everything 4G63 and even the 420a engines (non turbo'd eclipse/talon 1995-1999)
