Hi all, it's come to that time for modding my Evo 7, I've just upgraded the pump to Walbro 255. Soon to come is GC S2 274 Cams & GSC Beehive Springs/Titanium Retainers, HKS adjustable cam gears. I also already have a K&N panel air filter, Exedy HD Clutch and stock turbo.

Now my question is, what fuel injectors will suit with these parts/power? It is my DD and I'll also be getting a full turbo back exhaust soon and dual mapping for e85.

I don't really plan to add many more mods after these, but would like to already have the right type of fuel injectors if I do.

 

So i assume you have a stock turbo? and running regular premium gas?

 

Yes, Stock Turbo. Also plan on dual mapping for e85, since it's available close by. Otherwise yes, premium fuel.

you would be fine running 880s with a stock turbo and e85 but you might as well go with 1000's or 1200's just incase you decide to go bigger setup. The price difference between those sizes isnt that different either.

 

From the reply's I've read along with some extra research, I've decided to go with FIC 1050cc Injectors.

 

Our DW1000 and DW1200 low-impedance injectors are drop-in fitment for your Evo VII.

We also have high-impedance options available, as well.

 

If i went with FIC 1650cc Injectors would that be overkill with those mods? Cause I would be looking to add more performance parts at a later time, which might require larger injectors like 1650cc.

 

Agree with the above. If you are going to be upgrading to parts that require 1600cc injectors you might as well spend the money then to get them since you will be dropping dimes anyways versus sacrificing drivability now.

Here nor there if you have your mind made up but highly consider the S1 cams for the stock turbo. Been running a 30R with the S1's and am definitely not being held back by any means with these cams. Plus all around throttle is like driving a 400whp factory evo.

 

After a little more research, I think 1450cc will suit me best. My top goal would be 500whp at a later time. These Injectors should be right for me throughout and up to that point.
