Stock 4age 16v injectors sizes and colors

[Corollenertia]

the color of my injectors in the car are pink top purple is. I dont know what they they dont seem to be spraying fuel even though fuel is very present in the fuel rail I also got some blue to ones as well that came with the motor I just pup the pink ones in because the connectors fit them. but i need to find out why my motor isnt spraying fuel.

let me see if I can still remember this, ( got it's been ages):


orange top 340cc
blue top 450cc
purple top 550cc
yellow top 500cc
black top 325cc

That's what I remember from denso, but every brand out there is different, I would look into my charts but that fucking german guy keeps hiding all my stuff, what's his name?.. ah yes !ALZHEIMER, that's the fucker!

I dont know if they are denso the pink purple ones because the plugs are totallt different from the other set. and what are the stock injector size for a 4age

ok... those numbers are way off.....

early bigport 4age's are 220cc @ 48psi (blue top), low ohm
later bigport 4age's are like 240cc @ 48psi (tan), low ohm
smallport 4age's are 250cc @ 48psi, high ohm
silvertop and blacktop use the same (side feed) are 270cc @ 48psi, high ohm
4agze is reddish and 365cc @ 48psi

yes, people have gotten higher numbers from those that blueprint their injectors... but those tests are generally done higher than the stock FPR keeps the fuel at

Most injector shops spec (or should) the flow ratings at 3 bar (43.5 psi) as it is the so-called standard. Unless of course the customer requests another test pressure. Unfortunately different shops use different fluids for testing and will cause some difference readings.

Can i use smallport injectors to a bigport?

I don't think you can use like that.

Reviving an old post. Are there different 4agze injectors for small and big port generations? i.e. high and low ohm?

from the research that i've done, it appears that the 4agze only got 1 injector its entire lifetime.

i used the following link as my primary source for info:

I know it's old, but I am going to try... I am putting a small port in my AE86, I heard somewhere that there is some difference between the injector wiring, but then I get told by some that the whole set up is plug and play. I want to use the red top ECU and the blue top harness, but I was expecting some wiring problems. What I really need to know is if my red top injectors are going to need any special modifications (high ohm?) or if swapping my ECU will take care of it. Is there anything else in the fuel system I would need to change?
