Sounds not right, however hard to see in the image and completely understand what you refer to. Best to see a a fellow club member in your area (compare engine bays).
Also lots of online images to assist and Toyota bgb.
The factory ct26 turbo is water and oil cooler, so should be twin connection to oil from underneath and twin water lines facing the engine. Line on the housing connected to wastegate actuator.
The factory blow off valve needs a line connected to the manifold to reference the pressure. Should have a plastic VTV one way valve that I can’t see (expensive, $80 plus postage from puremr2).
When buying a project, especially a 25 year old Mr2, best to go through all the fundamentals, replace known fail items and then drive with confidence and reliability.
