Injectors..

Whats everyone's recommended size of fuel injectors on a big 16g turbo?

 

[herostar]

either 550cc or 660cc, depending on if you're going to go bigger or not

ya that sounds about rite, if u got a command flow, u can take full advantage of these injectors, or raise the fuel psi to get even more fuel out of the smaller injector size

if u got a command flow

550cc

david buschur runs 7 sec passes on 660cc injectors in the 1/4 mile. now thats something to think about. :laugh:

550's all the way.......but you could do 660s as well especially if you are ever considering converting that b16g to a 20g.

And of course that means *JACK* for anyone wanting to run the car on the street, since Buschur does that with high fuel pressures that make the injectors flow more. But 660s should be fine, like you said.


I have FIC 850s on my 2G, and with the DSMLink, it idles like stock. I will never have to worry about injector size no matter what Turbo I use, and pumpgas is not a problem. I think standalones, Greddy EManage or the new MAFTranslator may be able to do about the same thing the DSMLink does with fuel.

Heres how I think you should decide:

Use a couple mathematical calculations to determine what injector size you should use. I recently just posted these formulas on my website if you want to see them. I also put those formulas an Excel spreadsheet where you can just plug in the #'s and it will do all the calculations for you!

go under articles and reviews section, click on Fuel FAQ.

Hope this helps.

There you go, not only can you choose the right size now, you can choose it 4 times!

You can run the numbers once for each cylinder! :laugh:
