welcome to the forums, this site is a great resource for all info on 4G61,4G61t and 4G63t swaps, so you are at the right place.
In order to swap it over to turbo, you will need ether a complete wire harness from a car that has the turbo 4g61 motor, or you will need some form of stand alone engine management, the turbo motors have a different wiring then the non turbo 4G61t, and if I recall correctly some sensors are different.
Thats why, in some cases, its a good idea to get your hands on a donor car to pull all the parts you need from, also a 4g63t swap should be looked at as an option, just in case you don't find a 4g61t donor car, you might have better luck finding 4g63t cars but you need the 6 bolt or early 7 bolt I think the mounting setup changed on later 4g63 cars.
There are a lot of threads on here that have good info on the subject, I feel that after you read a few build posts you will get a better idea of whats involved in the swap, have a good one.
Thank you so much for information
