do i need to get a turbo's driveshaft and a rear diff to make this swap work? or can i mount it up to the stock non turbo stuff and it be fine? for a little while...

 

If using a turbo transmission, there are 2 options:

1) Use a turbo driveshaft and rear end
2) Use a custom turbo driveshaft with an NA diff flange. You can buy one from Mazdatrix or have one made from an auto driveshaft. The auto driveshaft has the turbo yoke and NA diff flange, but is 2" too short & must be extended.
