Help Me Identify My Injectors

[DRAGTS]

Hi Guys,

I've just had some serious work done on my engine (series 2 gtst). I'm pretty sure the stock injectors have a purple colar, mine are brown and when tuning had to cut out alot of fuel, so i'm assuming they are after market, can some one help me work out what they are???

Cheers

maybe ask the person who did the engine work?

As far as I know different manufacturers use different colour codes. And they sometimes change them with new models etc Then you can take an injector and have it hiflowed!!!

If they aren't at full duty cycle I wouldn't worry about it.

Without supplying what mods you have no one can even guess.

i.e powerfc, highflow etc?

Chances are they are standard as the car wouldn't have ran well at all on larger injectors.

I'm not sure why you would need to know what the other mods were to identify the colours of the injectors.

For example, i know what most of the nismo collars etc are, but neither my mechanic or myself have seen this colour before, but so far seems to be getting heaps of fuel, so will have to wait and see when we tune her up.

well it will help get a rough idea if its a stock gtst then they will be stocker injectors as it will have a stock ecu, its not like you would have a stand alone ecu on a stock gtst with bigger injectors. if it has cams, stand alone, bigger turbo etc they a logic guess would be next step up say 550cc and if theres a resistor pack then GTR ones could also be a logical guess

Its quite simple really... If your running a highflow turbo pushing 20psi and still having to trim fuel then its obvious you have larger injectors.

You need to be a little more specific when describing your problems in the future. Give all the information you can if you want help and not get all secret about it when asked a question about it.

For example... how much power is it making, what other mods are done to the car when you bought it and what mods have you since done to it, where was fuel trimmed (idle, cruise, wot 2000rpm, wot 3000rpm wot high rpm where and by roughly how much)

We are all here to help each other.....

Yeah, sorry, no secrets to be had here, if there was i wouldn't have a build up thread. The simple answer is when i brought the car it was blown up due to hydrolic lock. So i've still never actually driven the car. When i got it it had AVCR, Power FC, Larger Fuel Pump, Turbo back 3inch, FMIC, Pod. So only some basic mods. I know from experience that most series 2 r33 injector collars are purple. Mine, as mentioned are brown. I thought someone may have come accross some brown ones, be they stock or aftermarket, and may have been able to identify them. So yeah nothing to hide, just that what i have done to the car has no bearing on what was previously fitted to the car, so nothing to hide, just didn't think it was relavent..

Again, if anyone might know that would be great. PS, the old owner didn't have any idea either....

Cheers
