Please could you advise me on injectors, I have a contact who can obtain RX7 injectors from turbo 1 and 2 jap imports, the question is what is the flow rat, as I have had them tested at a local injector centre they came to the conclusion that they delivered 284ml/min. however I presume this changes at different fuel pressures?
There seem to be two styles of injector plug one square and one oval (I believe this is early and late models and is connected to resistance?)
The vehicle these are to be fitted to are a nissan skyline....eek
does anyone know which are suitable resistance matches?
Just to clarify the injectors are purple denso

Thanks Chris Py

There are basically 6 types of injectors for 2gens. Some of this may not apply to you overseas guys who didnt get the nonturbo versions. By the way, low impedance should test approx. 2.5-3 ohms, and high impedance should test approx. 13 ohms. Ratings given are for stock flow rate from the appropriate stock fuelpump. Note that some injectors carry the same *part number* while being a totally different injector from another with the same number(high or low impedance) thus you canot rely solely on part numbers...

86-87 nonturbo low impedance 460cc square plug center notch red 195500-1350

88 nonturbo high impedance 460cc square plug offset notch purple 195500-1350

89-91 nonturbo high impedance 460cc oval plug center notch red 195500-2010

86-87 turbo low impedance 550cc square plug center notch beige/tan 195500-1370

88 turbo high impedance 550cc square plug offset notch purple 195500-1370

89-91 turbo high impedance 550cc oval plug center notch purple 195500-2020

Also common are 1gen injectors:

This info should be stickied...... very good info hypntyz7
