resistor pack for injectors (impedance question) - Toyota Nation Forum : Toyota Car and Truck Forums

Nico · 03-26-2004, 05:01 AM

I have nearly found all the parts for turboing my 5sfe and have got an injector impedance question. I managed to find 7mge injectors (310 cc) for 1 buck so I can't say I have been losing money but since it is from 1987 I think it is a low impedance one, isn't it ? Is there a resistor pack option that could solve my problem and allow me to use them without any problem ? (since 5sfe ecu is for high impedance...)
Thanks for your help and advice !

According to the chart below, 7M-GE injectors come in high and low impedance.

mines have got a yellow head. Does this confirm it is low impedance ? Sorry I am a bit lost with these low/high impedance problems

And if it is low impedance, does anyone know about possible resistor pack to use or is that something not worth to try installing ?
Thanks !

hey nico seems you foudn all your turbo parts pretty quickly where did you look for everything???

as far as the yellow tops they are low impedance. what you need are the light green MKIII injectors. You can get a resistor pack from Bosch if you wanted to use those yellow tops anyawy. butyou might as well just get the light green top ones.

Hi Luisitol ! Thank you for your help. In fact I have been finding them mostly on ebay (that was a battle really), a few in the local junkyard but I have to say it hasn't been especially easy !!!!! I also made a search on Google which lead me come up a few interesting stuff. As I already have those injectors I think I'll try to go with a resistor pack. Would you know a bit more about this Bosch stuff ?
I know you are also still looking for parts with exactly the same goals

if you are interested I can possibly give you some links I have (in the US) depending on the parts you still need. I'll be out for the weekend but I will be back on Monday.
Have a great weekend !

Hey Nico if you want more info n the Bosch resistor pack TOny is the person to ask on those i believe. I know a lil bit about them but TOney would know best since i believe he is actually using them.

Hey any links you have would be great man. we should talk on AIM: Fastrackny
