Welcome to the forum
If you run under 7psi of boost then you don't need to change internals, above that and you can start breaking stuff without doing upgraded parts.
You can just add a custom turbo setup and use your current MAF computer as long as boost is under 7psi.
You do need to oil the turbo fan, which is not to hard to plumb.
