Hi Guys;

I posted this to the other list recently - post bounced here again?

I did some more digging on the rx7 fuel injectors.
Here is a stolen list of fuel injectors info:

(Note that some injectors carry the same part number as others but plug styles and resistances can vary.
Low impedance refers to 2-3? ohms, high impedance refers to 12-13? ohms)

Year   type   impedance plug   plug     flow   color  part
                        Style  Notch    Rating        Number
                               Position

84-85  13B NT low       square center   680cc  orange 195500-0900
86-87  13B NT low       square center   460cc  red    195500-1350
86-87  13B T  low       square center   550cc  tan    195500-1370
88     13B NT high      square offset   460cc  purple 195500-1350
88     13B T  high      square offset   550cc  purple 195500-1370
89-91  13B NT high      oval   center   460cc  red    195500-2010
89-91  13BT   high      oval   center   550cc  purple 195500-2020

MSD-2400 will fit the square center connectors - http://store.summitracing.com/partdetail.asp?part=MSD%2D2400

AC Delco PT425 (GM dealer 12116252) - discontinued - will supposedly fit oval center connectors.
NAPA  Echlin 2-18457

http://www.fiveomotorsport.com/Injector_CONNECT.asp - see *NipponDenso*
  I have ordered some of these, should know if they fit shortly.

Also possibly:
  BMW 6113-1358-330,
  GP Sorenson part 800-9416
  Standard Ignition Corp. SK-25

It is also worth noting that the oval center connectors appear to be a Japanese only design - Toyota (and others) appear to have also
used them in the following engines 22RE, S3-FE, 4A-FE.  E.g camry 2001V6sedan looks like it uses the same NipponDenso connectors.

As an aside, here is an interesting thread on cleaning your fuel injectors:
