can anyone help ID these injectors?
 

OK so I finally got around to pulling out my injectors on the motor i just bought. Wow. The injectors look haggard as shit.

Anyways here's a bit of info. on 'em.

2 of them - orange top. have the DSM logo on them. Have '2071' printed near the top. say '927' near the clip.

the other 2 i pulled off - black. say 'siemens deka'. on side near the clip says 'a4' the opposite side says 'a8'. from what i've read siemens injectors are hi imp.

any chance anyone can give me the cc rating of these before i spend the money to have them cleaned?
will provide pictures if it will help.

thanks!
