Has anyone tried using these on an LT1? Will they fit? How about the plug? The RX7 Turbo 2 models used a high impedance 550cc injector, which equates to about s 52#/hr unit. These are a lot less costly ($200 vs. $500) and more plentiful than the 57#/hr units.

 

I remember hearing about these... I believe you'll need an impedance converter to make em work

 

They are a no-go. The power plug is slightly different (it would fit with minor mods), but the tops & bottoms won't fit in the rail/manifold.

Looks like the Siemens are the only high-impedance choice.
