will the rb headers for a 89 fit a 88. just the 5th and 6th ports wont work???

 

Your 5/6 ports will work just fine. The S5 cars have them actuated off an RPM switch in the ecu and pressure from the air pump.

 

will headers from turbo model fit NA or visa versa

 

turbo cars dont have headers

how ever you can buy a tubular turbo manifold, that could be called a header.
