what can i skip? vacum and sensors
 

Have some questions reagering all the sensor's on the 2JZ N/A Engine, i currently adding an turbokit and are not planning to run Aftermarket ECU. So my questions is, what of all these sensor's can i skip and what vacuum hoses and stations can i skip? As i understand is one of them a map sensor?
Or can i just remove all the vacum that is already there? Im going to run a custom welded intake manifoild. and are going to use vacum on, pop off, FPR, wastegate. i dont need vacum on anything else?
and is it anything else i can skip? are not going to use the car at road, just racetracks
