Identifying GSL-SE Injectors

Can anyone tell me the numbering on the GSL-SE injectors?

They're supposed to be high impedance, 680cc right? Orange connector sound right? Top feed is obvious.

I've heard of some 720cc injectors. Are these stock or is that a made up number?

Witchhunter.com is your friend.



680 is Denso's rated nominal flow rate. Witchhunter's number is based on what they actually flow across the injectors they've tested.

680's are normal stock injectors for a GSL-SE

Most injectors flow just a little over there rated amount.

You can get 720's they normally have a blue top

Low impeedence, tan top, part # 199500-0900. High impeedence didn't come in use until mid-87. This is an 84 injector number. There have been rumors that 85s put out more than 680 cc., but I believe the part #s are the same for both years.
