About a year ago I sent my injectors out to RC engineering for calibration. Man were they messed up. I've probably put 10k pretty hard miles on the car since then running a G-force ECU. I'm thinking about going to larger injectors down the line so i kinda dont want to take my stock injectors out until the time comes. But since I'll be putting in my Power FC before i upgrade injectors i was wondering what the probability of my year old injectors being within specs is.

What do you guys think?

Thanks.

 

Bump.

I know some of you might know something on this one...Chuck, Carson, Jason, Stephen, Tim, and even Rich maybe.

 

one last bump.

 

I'm sure they won't be as clean as the day you got them back from RC, but I have NEVER heard of anyone getting their injectors clogged in a year, unless you are not running a fuel filter

I would reuse them. It took mine about 80k miles and 7 years before they got pretty bad.

 

They're probably ok but to be on the safe side you could run an injector cleaner like BG through the fuel rail. Most shops that work on Rx7's will have the equipment to hook up to the fuel rail and do the flush, usually cost about $40-50 for parts and labor. A dealer could probably even handle this but might charge more.

You might try a search, I know that a while back it was discussed on here and someone had the part#'s and source for the cleaner and tool to hook up to the fuel rail.
