SR20DW to SR20DET

Ok ik this is proly a dumnass question but whats is the difference between the sr20de and the sr20det ( i get the turbo part but what else). I just bought a 1993 G20 with the SR20DE in it but its got mad miles (153k) i was thinking about swaping it to a SR20DET but couldn't i just rebuild the engine and make it a SR20DET? What would i need, wouldnt i need to get a all new drivetrain for rear wheel and what not or could i just keep it FW.
