because colton i would have to FIND a turbo 4g63 and then have the money to buy the engine...then all the parts to build it up. Remember i rebuilt my engine like 20k ago with EVERYTHING new so i did NOT want to redo all that stuff i already did. THen you have to worry about your tranny bolting to the turbo block. Now if you could get your hands on a crashed turbo 4g63 with the tranny and motor then that would be ideal. But if you have a few parts and your motor is in good shape then go ahead and save A LOT of time and money and turbo your N/T.
