hey guys, i just bought rx7 injectors pretty sure ther 550s. im gonna put them in my b16 when the rest of my turbo set up arrives..just need to know if i still need to use my resistor box or if that can be removed? thanks in advance

 

Measure the resistance across both pins of the injector...

If they are 2-3 ohms, YES...if they are 10-13 ohms, NO.

 

The 550cc injectors will be tan tops. Red or purple are 460cc, and something else is 880cc.

Check the resistance like xenocron said.

 

thanks guys
