Default Can anyone identify these injectors?

There are no stickers on them. All they say is SIEMENS DGK and the other side says 3105 on 3 of the injectors and 3145 on the 4th injector. does anyone know what these are?

quick google on the 3105:

http://www.fiveomotorsport.com/Injector_MILLED.asp
83# lb/hr 850 cc/min

3145 = 750cc/min

it is possible that the flow has been matched.
get em bench tested.

I've used those 3105 in several different applications, including a nice street civic with a GT3567R. They are VERY reliable from my experience

thanks for the info, does anyone know of a reputable company that would flow test them /and or match them? they dont seem to be very expensive injectors. Is it worth it if I want to use them?

i think the o.p. is going off of the fact that they are 2 different numbers with 2 different flow rates, assuming someone had them matched. not necessarilly saying the injectors are bad or not, just not matched.

the 2 munbers he gave, i saw 3x 850's and 1x 750.

rc should be able to clean and balance them.
