What color are the 850’s.  Both primary and secondary injectors in my j-spec 20B are a deep red/crimson color.  I think it is a ’93, but I’m not sure.  You’re probably right on the 3rd gen 13b’s having 850 cc secondary injectors.    
 
Mark, I don't know what color they are, but I know they aren't interchangeable with the 2nd gen injectors.   
 
Why would they use 850's if 550's are more than enough to cover the power output? 
 
The FD ECU limits duty cycle to 63% is seems.  With aftermarket computers allowing 80+%, the stock injectors are good to about 320 HP.

So look at it :-) 
 
Gotta go,
