Difference in Fuel Inj

Was wondering if there is any way you can tell the difference from 550cc and 720 cc fuel injectors by "looking" at them.

Part numbers on the injector itself. Theres a thread around here somoene that lists them depending on what model you car is and what the stock injector part no will be.

I just woke up. What does *as long as I need LI?* mean in some other words? Just woke up here.

The 680's should work in your 88 .....but.....you have to solder a 10ohm resistor in each injector plug that goes to each 680 injector.

Racing Beat and Mazdatrix both, I believe, recommend the 680''s in the secondarys for hopped up engines.

It sounds like "LI" means "low impedence".
