I want better performance and better injectors so what would be some good injectors for my stock evo to boost some performance?

You need to give us a lot more information before we can help you. Start by answering these.

What type of fuel do you plan on running?

How much HP are you shooting for?

Do you have an upgraded fuel pump?

How much boost do you plan on running?


There's more questions to answer, but if you answer these we can help you out better..

I plan on running e85 In the future
I am ordering a Walbro 255lp fuel pump . Right now it's stock
I'm shooting for 400+ hp and I'm not sure how much boost

I would get FIC 1600cc "high-z" injectors, personally. It give you some room to grow, just in case you want to shoot for higher HP

1600's without knowing what turbo he's going with or any other mods he plans on running ? I'm going to be running an FP black with 1100 high z's. 1600 will be way overkill if he goes with any turbo smaller than a 6766, LOL.

I was going to say 1050's if you plan on going with a turbo back exhaust, intake, bov, 255 pump and 9 turbo. That will get you to 400.

he said he plans on running E85, 1050's and E85 will not get you that far...

I ran 1050s on my evo 8 on e85 I had no problems..

There is nothing overkill about injectors. He could buy any 1500+ cc injectors and he'll be fine, it's all about scaling the injectors properly. Which any good tuner can do. He may want to upgrade his turbo.. I'm just for buying injectors once, they're relatively the same price.

I have had the FIC 1050cc low impedance on my previous E-85 Evo IX SE and now I am running FIC 1100cc High impedance injectors, I am at around 400whp with the cams, the exhaust, intercooler, E-85 tune etc. My current 100cc injectors put me on a relaxed low to mid 70% injector duty cycle at full boost(28-30psi) on a evo 9 turbo.

Ultimately it will depend on what turbo are you putting in the long run. start with 1100cc and you can go wrong.

this.

no point in buying injectors that could be maxed out and need to be swapped if he ever upgrades the turbo

fic 1100's are good for 491 whp on E85.

I wouldn't recommend just buying the biggest injectors available, its much better to determine your power goals for the immediate future and plan on getting an injector that will allow you a comfortable amount of headroom and even a bit of room for growth (but not double or triple the flow that you require currently). The reason for this is because sometimes excessively large injectors require more work to tune so if there is no real benefit to going with a huge injector for you then it doesn't make sense to go there.

To make 400 whp on E85 on an Evo, I think our 1100cc injectors will be a great fit. Based on our calculations here you wont have too much extra headroom at 43.5 psi of base fuel pressure but if what fromWRXtoEvo is saying is correct, his real world results were more favorable which is certainly possible since we keep our estimates conservative to be safe. If you do need some more fuel flow then turning up your fuel pressure a bit is an option as well, down the road.

Wow. That's impressive for 1110cc. I retract my original statement, he should be fine with the 1100cc's. But... If he plans to go bigger in the future, I would still buy bigger injectors

excuse the thread revival but are the delphi/lucas 621061 120 lb (1260cc) low impendence any good for a 400hp goal on a evo 9 turbo with tbe, dp, licp & intake?
