make sure that they are in fact rx7 injectors...check this out...

WitchHunter Performance - Subaru Fuel Injector Modifications

About halfway down the page it reads...

This part is just for your information only.

Are having trouble tuning this type injector?
Many customers are sending these injectors for cleaning and testing, but we have found most of them are fine and work as intended. These injectors have the part number 2450 stamped in the top plastic. The problem here is that they are are a 15+ year old Denso design that were intended to be used as the for the 93 to 95 Mazda RX-7 turbo engine. It was a secondary injector that only operated during full throttle and high RPM conditions. It was never even operating during idle in the RX-7. These are now being sold by some people as a WRX injector upgrade, but it's the same old technology injector with a spacer and different o-rings.They were not designed for use in a multi-valve new OBD II system.

Care to share the latency since you brought it up...

For reference if anyone decides to go this route.
