If you are planning a swap to the 3sgte, yes, it will drop in. The N/A tranny will bolt up to the turbo motor, although I believe the tranny has very slightly shorter throws. I can't quite recall. Anyways, if you plan on doing a tranny swap to accomodate the turbo motor, you will have to get the turbo axles/hubs. To run the 3sgte, you'll also have to run the proper ECU and wire harness for whatever generation motor you are running. There are 3 generations of the 3sgte. The N/A's cooling system has known to fail on the 3sgte, but if not driven hard, it can be stalled for a later time. Also, a more powerful fuel pump is highly recommended as well.
