RB25 S14 wiring/plumbing

[uashes]

So I've inherited a project car im trying to get up and running. Ive got a rb25det neo for my s14. Built block stock head for now and lots of bolt ons. I have a few unanswered questions.

With the aftermarket intake/exhaust manifolds having no use for the original manifold's sensors, what consequences will i have deleting all but the necessary sensors? Like the traction control to the TB etc.

Ill also be running an external oil cooler but the stock oil warmer has sensors built in. I suppose i could relocate them but do i need them?

Also can i delete evap items such as the charcoal canister and purge valve to reduce wiring/complexity?

I know the questions are a little broad but im just trying to find the right questions to ask to wrap my head around wiring/plumbing this thing.

Thanks in advance
