Do you have to have an injector harness for Greddy injectors? I went to put mine into my engine today, and the stock harness didn't go onto the plug on the injectors.

 

you need 86-87.5 connectors and a ressistor pack because i belive your car has high imp injectors and greddy 720's are low imp. search fro moer info.

 

I thought that the 86-88 were the low imp? I just need to figure this out cause I want my 7 back on the road as soon as possible

 

nope 86-87.5 were low imdependence and 87.5 and up were all high

 

Well, my new engine is a J-spec S4 engine. So it could've came 87 or 88...

 

They had turbo motors in 86 unlike the US also

low impedence have a center lug on the connector, high impedence is offcenter.

you can cut off the lug from the injector with a razor blade which will allow the connectors to fit but then you will need to solder in 10amp 10ohm resistors into the wiring circuit to each injector.

good luck

 

here are the injectors if it helps.

 

if you need help with it let me know, i can help guide you through it.

i've done the swap before without changing the connectors.

though changing the connectors might not be a bad idea because they tend to get brittle after years of use.

 

Well, I've been thinking about it...do they make low impedance 1000cc's that would fit the FC?

 

did you use the jspec harness?

 

yes 1000cc PTE injectors. I have them installed on my car with the stock fuel rail and no modification. Search and you'll find details.
