For a tdo4 setup you need
Tdo4 turbo off a suburu and rotate it to fit the starlet, standard actuator off the tdo4 will need to be mounted in a different place to work properly
Braided Oil feed as you said
Water feed is optional, but your better off connecting it up to help cool your turbo
You could do with a front mount intercooler too
That's the basics of what you need for the setup
But you need some sort of engine management, boost controller, I'm not sure what sort of setup you have at the moment, but you need quite a few other things if you want the car to handle the extra power like updated clutch, uprated brakes or pads minimal, it all depends what power you want out of it really
Hope this gave you an idea
