where is the pressure sensor on a 1986 N/A rx7

 

Right front strut tower. Just in front of it. Black rectangular item. ONe electrical plug, one vacuum hose.

 

I have mine disconnected, car runs better without the hose connected. Is there a reason for this pressure sensor anyway?

 

is there a difference between the N/A and a turbo

 

if you take off your map your car will run should run rich. Yes there is a difference bewteen sensors they start reading at different voltages.

 

As the factory service and Haynes manual shows, the pressure sensor is on the passenger side shock tower, facing the front of the car. There is a vacuum line that extends from the intake manifold to the bottom of the sensor and a harness connection as well.

 

Yeah, never swap the two b/t cars.

Disconnecting the boost/pressure sensor means the timing WILL be off as you drive and the secondary injectors will come on any time you reach 3500 rpm (not a normal operation of the secondary injectors). And I won't mention how it will effect the operation of the emissions control such as the Port Air solenoid etc.

 

what if i am converting to turbo

 

Then yes you must switch it.. Providing you mean tII swap. If you are going N/A turbo then I wouldn't know

 

actually twin turbo

 

Please elaborate.

 

i am converting an 1986 N/A to 1993 twin turbo

 

The pressure sensor measures boost. Doesn't care where that boost comes from.

Besides, you should not be using stock EFI stuff anyway...
