can someone teach me on what kind of injectors these cars have??
i know their low impedence but when im looking through summit it talks about paek and hold, 12volt ci cuit and other randome crap i dont get

 

From the 2nd gen FAQ..

What size injectors does my RX-7 use? What colour are they?
Year Engine Plug Size Colour Part #
84-85 13B NA, low square center, 680cc, orange, 195500-0900
86-87 13B NA, low square center, 460cc, red, 195500-1350
86-87 13B Turbo, low square center, 550cc, tan, 195500-1370
88 13B NA, high square offset, 460cc, purple, 195500-1350
88 13B Turbo, high square offset, 550cc, purple, 195500-1370
89-91 13B NA, high oval center, 460cc, red, 195500-2010
89-91 13B Turbo, high oval center, 550cc, purple, 195500-2020

 

for the record they are not all low impedance

 

The big question would be. Why are you replacing your injectors?

 

cuz my primaries are fubar and the car has the classic symptons of horrendous injectors..

well i know what size the injectors are and that theyr low impedence but i keep reading on injectors like 12v cuircuit, peak and hold, 4/1A paek and hold, and what not so ineed to know whats what so i can buy them right the first time

 

How do you know your primaries are bad?

Send the injectors out to www.witchhunter.com if you believe they are bad. Only $19.00 per injector to clean and test and quick service.

If you are hell bent on getting new injectors then forget about all the BS and find a place that sells them according to your year make and model.

 

+1 for witch hunter, he did an awesome job on mine.

 

search: injector rehab.....(.com) great job on mine will send detailed info before and after of the test runs also it can suck sending your injectors off with money but they not only come back in like new condition but they will also send you the old parts taken out not sure on price worth it

 

Peak and hold = low impedance

Saturated = high impedance
