are 87 t2 550cc injectors low impedence or high impedence??

 

tit depends, mazda made them low impedance until half way through 87. if you remove the airbox there should be a large metal box with heatsinks on the top of it. it has one black wire and four brown wires coming out of a very large connector. if you have this box then your injectors are low imp. if not then they are high

The 87 chassis earlier than JMIFC331 H0500001 550199, are low impedence. The chassis above that number are.......Right.

 

but how to check w/o a car?
I bought a S5 J-spec engine and still useing the J-spec injectors, but i dont know are they high or low?
thx guys

 

all S5 are high (your jspec)

87 depends on the month. it changed half way though

have fun putting your s5 engine into your S4 car.....

 

already done
ths guys

 

and I chnged low to high
do I need to do something else?

 

yes it won't work...

you have to match the ECU + injectors + resister pack


what you need to do is remove and bypass your resister pack now

 

what's dieffrant between high and low?
if I changed low to high and do nothing else wut will be happened?
I changed low to high and didnt do anything. I think that's why I am useing hell much gas right now.
thx guys
