Need help with injector size for e85

[dustin_8907]

I have an evo3 16g and 255 wally and good fpr. Dsmlink on speed density setup. I am going to run e85 and need to know what injectors to get to basically max out this turbo. Thanks

E85 airflow support chart (bottom of page): baseinjectordata [ECMTuning - wiki]

According to that chart, 780cc is the absolute minimum for the Evo 3 16g airflow potential (42 lbs/min). However, for the safety of the engine and longer injector life, I'd go with at least 950cc.

Dont buy injectors twice dude.... Just get some 1600+ and be done with it. I know its way more than you need NOW, but later if and when you upgrade, youll be set and wont have to shell out another 400 bucks.

Okay thanks, would 1200cc work fine with my fuel system aka 255lph pump and fpr. Just wanting to know because I may jump to a larger turbo in the future. Thanks

Okay so 1600cc would be good for future turbo upgrade such as fp green etc.. ?

I will get 1600cc then, is there a particular brand that's best but not overly priced?

Get some Fuel Injector Clinic 1650cc's.

I actually have a set for sale right now for a great price. PM me if interested.

^^^bingo. You can get everything you need in the classifieds. And way cheaper than new. Look around, theres some for around 300 i saw the other day, think they were 1550s or 1450s, both would be fine, finesse's injectors would be best though.
I bought 1000s thinking "I'll never outgrow these". It hasnt even been a year and even on pump im now near 90%IDCs , so i too wish i had just listened to others and bought larger injectors to start with.

Injectors and a little more info about fuel pumps here as well. http://www.dsmtuners.com/forums/articles-tuning-ecu/253452-e85-injector-max-lb-min-calculations.html

1000's would be more than enough for a 16g, and you'll run out of pump way before then.

Any low impedance injector over 1200cc is a waste of time. On a 16g, 1200cc injectors would be your best bet!

So pte 1200cc would be better than 1000cc ? I don't plan on going any bigger with my turbo so which should I get? I want to save as much money as possible

if your not then I would just grab a set of cheap 950cc.

I have a 950cc fic now and im logging around 85 idc with my e316g at 28-30psi

thats on a cold night logging and getting 40is lbs/min

Most of the time, it doesn't cost much more to go bigger. If you want a good price on injectors, PM me and I'll set you up with whatever size you want at a great price!

If going e85, I would get 1600 at least.
