i purchased a s4 turbo engine a wile back to use for parts to rebuild my blown engine. it had green top injectors on it witch confused me. i thought it was supposed to have tan? they seem to work fine so far but i havnt done anything other than start and slow low rpm driving. but like i said they seem to work fine and engine runs good with very good pull out torque. it accelerates better than my other stock NA car at less than half throttle with all driving staying under 4,000 rpm. but i have been searching for the past few hours on google and on the forums for green tops and cant seem to find anything other than supra 305cc injectors witch i dont believe are it. these look identical to the orange tops from 86NA other than they are green and very slightly smaller circumfrance. but any help of the specs of these injectors would be great. thanks in advance.

 

o and i forgot to mention that i will post the numbers on them asap

 

Googling the part number is the best bet. Witchhunter has an extensive list of injector part numbers and flow rates. The colour is basically irrelevant.

If there is any ambiguity (injectors can be resized) then have a local injection shop (Yellow Pages) perform a flow test.
