Tracy,

I will be using the yellow injectors for the primary's. Using your
injector disable \ double pulse wiring method I would rather have the
larger injectors.

(can't bring myself to use a grinder on the block)

I originally used the "fat" RX-7 injectors in the Renesis by simply
taking a carbide bit in a die grinder and removing the interfearing
metal on the Renesis block.  I am now using the stock Renesis injectors
(Red pri & Blue Sec.).  I recommend using them as-is.  Mazda knows what
they are doing here and unless you plan some *really*  big HP from the
Renesis (not recommended) it is simply not needed.  The latest software
for the EC2 handles the differing flow rates on the secondaries nicely.

You CAN use the 4 yellow injectors from the 6 port Renesis if you really
don't want to use different flow rates in the pri & sec.
