Fuel injector Size

[irishgangsta55]

I was just wondering if anyone has an idea of what fuel injector size I should get with my precision 50 trim. If you want more info about my car just ask I can start to list things.

What are your power goals? What are you going to be using to tune with?

Off the top of my head, I'd say 850s or bigger, but you'll find a mountain of information on this subject using the search feature.

if he can tune it out does it matter how big the injector is ( i mean as far as how big you can go) ? I havent upgraded injectors yet so therefore didnt have the reason to really look into info on them

Like isnt it true he might as well go big as his needs could be so he wouldnt have to keep getting bigger ones later?

It may be more difficult to get the larger injectors to idle properly because of the size of the nozzle/flow rates. Imagine a small injector to be a garden hose and a large injector a fire hose. You can control the flow of the garden hose a lot easier than a fire hose right?

Please fill out your profile, it makes giving advice alot easier. And big injectors with quality tuning devices really arn't a drawback at all. I use 850's with dsmlink and the car has stock drivability. My friend Dj has 1600's on his car with aem ems and it also runs great. 650's will be fine unless you have the mods to max out the turbo. 850's will support over 500whp.

see this is what I thought ....^^^^
I plan on 650s on a Safc2/ wideband/ afpr / supra 260lp fuel pump/ fmic/ full 3in exhaust system/ and a ported super16g

does this sound like a decent set up to max out the 16g properly?
Or would one think I might as well get larger injectors than that, and if so what size?

this is a valid point though.... But maybe not an issue until you get into the really big big injectors....
