Help picking injectors

[turbo4awd]

Im not sure what size injectors i need. I want to run e85 since there are around 6 to 10 e85 station close to my house now. At the moment im running 680s with a evo3 16g. But im upgraging to a t3 pte 6265.
Will 1000cc injectors be enough or do i need bigger thanks for any help..

Also on a 1g is it ok to run 43 psi with the afpr

I'm changing over to e85 myself right now. From what i have learned, bigger is better. What are you power goals. I myself am looking at 600awhp so i got 1680 high impedance injectors and I run two fuel pumps. If you post your goals you'll have better help. As for the fuel pressure, it should be fine as long as you have a way to tune the ecu, something like dsmlink.

I have v3 with sd, as for power goals id like a solid 550 to 600awhp

Bigger is not always better. The bigger the injector the slower it is, harder to dial in dead times, harder to keep consistant. I ran 660s on e85 w/stock 2g fpr and hit 100%idc @ 20psi on a 16g.
PTE 50 trim @30PSI and 850s on e85 I was still under 90%idc.

Please stop posting info that is incorrect. Thanks


To the original poster for your current turbo i would say 1000's would be perfect. If you plan on getting a 6265 1450's would be good up to 650 to the wheels. But if your looking to make the true power a 6265 is capable of i would say get 2150's and call it a day. The reason i did not mention the 1650 and all those in between sizes is that they usually require a easy tune box so it get's more voltage. The 1450's are the biggest i would use with out needing a easy tune box. I was able to dial them in for a friend in 10 minutes and they idle great on gas and e85. The 2150's are a high impedance injector so only thing you would need to do to run them would be to get rid of your resistor pack.
