Ok I am rebuildng my motor and I am curious as to what size injectors I actually have. The person I origanally bought the car from told me they were oversized but did not rember the actuall size.... I have been told that you can tell from the color of the injector, so can anyone tell me what color the stock injectors are and what some popullar aftermarket size/colors are?

Thanks!

 

Send them out to RC Eng for cleaning and flow-rate testing.

If you don't want to pay for getting them cleaned, follow the procedure in the FSM and measure it for yourself.

 

The primarys are the longer tan topped ones which are 550cc's, the shorter red topped ones are secondarys which are 850cc's. But if you have them out might as well have them cleaned and flow tested to make sure you have no problems. ( comes from personal experiance) They could be bored and having them flow tested will determan that, bored injectors are usally engraved with a number and size though.

 

here is another option insteed of RC
