I'm doing a plus t on a series 1 rb25de Ives brought a nistune with 25det basemap already but I was curious if I can remap my original non turbo ecu to work with a turbo

No. Cannot Nistune an R33 ecu. What type Nistune chip have you got? That will determine what ecu you need for it.

You may be learning the hard way  - buy stuff that you know will meet your needs not just things that seem cheap.

I'm doing the job on a rb25 de cefiro and I brought the nistune off a guy who had it in a 25det Silvia, if the nistune is wrong for.the job can I remap the original ecu (25de) that's in the car to be able to run a turbo

No and don't keep opening new threads - stick to one.
