how do you tell leading from trailing injecdtors?
 

i got a spare set of injectorsa off of an rx7 thawt was rearended a feww weeks ago. i know for a fact thawt they re larger than factory, but i do not know how to tell the leading from the trailing. twpo of them say rc wengineeringt, the others have no stickers or engracviongsa

Leading injectors??? Trailing injectors???

Do you mean primary and secondary injectors?

In stock trim, injectors are all the same for both and interchangeable.

yes, i mean primary and secondary......these injectors are not stock. i know that they are aftermarket oversized injectors. i would love to ask the man who built the car, but he was killed in the wreck, so that is out of the question. is there any way i could test them or have them tested to tell them apart?

Anybody that services diesels can clean and flowtest injectors, and give you a report on their performance. You might as well get them cleaned since they're out.

i have had no luck finding a diesel shop with flow meters. is there ANY other way to test them? i want to know because the injectors on my car are stickin g (or at least a couple are) and i would like to replace them with these that i know are almost brand new

Dont replace them, just send them to RC Engineering to be cleaned. At $24 per injector you'll find its much cheaper than replacing them.

i already have injectors that are practically new, but i jsut don;t knwo which is primary and which is secondary
