   Does anyone have a suggestion for which injectors to use/
   I am running a second gen P Port.  Thanks for any help.

   Does not matter much Joe. If you are using four you need them
   rated at about 60 HP each at full rich (BSFC~ .6) The MSD 2018 would work
OK.

   The newer, skinny injectors, seem
   to have a wider dynamic range. In other words they will turn on fast
   and off fast.

   Pick the injectors with the high resistance. Around
   10 to 15 ohms. Most of the newer injectors are like this.
   The older 1 ohm injectors (peak and hold) take special injector drivers.

I would suggest getting an injector that uses the easy to get MSD-2400
connector.  They are available from Summit Racing, and lots of other
places, 8 for $24.  The MSD and Ford injectors injectors use them.  For
Mazda injectors, some can use them, some need a minor modification, and
others are different.  The green Ford 42 lb injectors are available at
reasonable cost from www.buyfordracing.com.  8 injectors for $199.

I have available 4 of the Ford racing 42 lb injectors, will sell them for
$100. Shipped free.

What are the part numbers on those Craig?
Low impedance or high?

Paul Lamar

High impedance, PN is on the box. Numbers on the injector top are: XL3V-A9A,
on the other side: 957 280 150 558 with 6 82 above that.
