My brother has a 1990 RX7 turbo II (S5), and he needs to know whether the injectors for his car are low or high impedance. He's at work right now so I posted this for him. Please let us know ASAP in a reply, and only if you are SURE. We're looking at some injectors that fit his car which are low impedance and need to know if they will work.

Thanks!

 

S5's are high impedance. S4's are MOSTLY low but they changed them but I don't know when.

 

< jun87 are high

 

Your bro needs to buy a volt meter

Cant go with out one when you wrench on cars.
