I'm in the process of getting parts for my project but i still cant figure out if i need 550cc TII High Imp or Low Imp..

I have a 88 GXL which i've heard need the Low's but than when i searched again i saw that the 88 was the switch to the High Imp. injectors..i dont wanna get the one i dont need and have to mess with changing the coils or whatever...Any advice is appreciated thks.

i already read that man. thats what i searched on the forum..but im not sure if i have a 87.5 car or not.

 

My 10th Ann Uses High Impedance Injectors And Its A 88. Why Dont You Work With The Harness You Get. The Low Impedance Injector Harness Has A Little Metal Box Near The Afm Plug. Or If You Already Have High Impedance Injectors And Have A Harness Made For Low Impedance Injectors You Can Modify The Box To Work With The High Imp Inj.

 

You have a GXL so you need 460CC injectors.

If you have a resistor pack under the airbox, you have low impedance injectors. You can also compare the numbers on them to the ones posted in this thread.

Or just measure them. Less then 5 Ohms is low impedance, more then 10 is high.
