They are different. You can upgrade to NBS turbo but you have to change the up pipes and pedestal also. You would be better off to stick with the OBS. You have several turbo options. You can use a smaller turbine housing, like a 1.0 A/R to get a quicker spool up and a little higher boost on top end. You can get a modded stock turbo from Beans (d66) or a H2 setup. With stock injectors, the 1.0 housing is probably better.

With larger injectors, the other two would work.
