egr does need to be swapped for usdm (if your area requires emissions)
oil pressure sender as ours read in kgcm whereas yours are in psi
possibly change the temp sensors as in 89+ they changed the plug type
throttlebody needs changing as throttle cable/linkages are different
you can use either the jdm ecu or the usdm whichever you feel like
injectors are the same as with the rest from memory
