Figuring out injector size?

[Retrostylz]

Hi,
I recently purchased my first DSM as well as my first boosted car. It is a 1996 Eagle Talon tsi AWD.

I have a 62mm turbo currently running 20psi (according to the kid I bought it from), but I am told that my engine is capable of handling that power. I'm not sure, but I'll probably lower the boost to avoid blowing my engine.

Either way, I am just looking to temporarily make my car a DD so my friend said he could help me with a simple tune. I am running far too rich on my AFR, and I can smell the fuel in the oil. I will NOT be driving it until I can get that figured out.

So, in order to get this properly tuned however, I need to know the size of my injectors. The kid I bought it from was, simply put, an idiot about cars, and when he had the engine rebuilt (because he blew up the old one) he installed what he calls "bigger injectors".

Now I am clueless as to what size they are. They are obviously not stock, and I refuse to ask the kid in fear of misinformation. So how can I figure that out?

I appreciate any feedback!

Take them out and post pictures please. Everything on them.

You're smelling raw fuel... in the oil?

Remove one of the injectors and post pictures. Alternatively, googling any part numbers will go a long way in identifying them.

Yes, I am running too rich. But now I notice I had accidentally added unleaded regular fuel when the car itself calls for premium. Could that be the cause of the rich reading on my AFR wideband?

I will post some pictures when I get home for work. Thanks for the feedback.

No. Octane rating has no bearing on how much fuel the ECU is telling the car it needs.
