Default 2011 wrx fuel upgrades

I'm looking into purchasing the new id1300 injector and a new fuel pump. Are new fuel rails required for the larger pump and injectors?

Also, is a new fpr required?

It all depends what your goals for hp are. Why are you upgrading your inj? E85? Larger turbo? It'll prob be a good idea to upgrade your fuel rails and lines if your going for a larger turbo.

Well, without knowing anything about your goals, think about how much more fuel you'll be able to deliver with a nozzle 2.3x bigger than your stock ones with the same size pump and hoses as before. The pump and rails will become a restriction before you max out the injectors, but I don't know where the limit is as I'm a photographer, not a tuner.

I'm going with the AEM 320 lph pump and ID1000s for my stock turbo because I want to mess with the fuel system once and never deal with it again until I want a bigger turbo and have the pull the motor to build it.

But more information from you is required before anyone can say anything definitive.

Current plans are to upgrade to a dw 265lph pump and Id 1300s. Run 93 oct for around a year then upgrade to an fp green.

Other supporting mods
Cobb turbo back exhaust
Cobb intake
Cobb ap
Pw tmic
Gs ebcs
Gs pnp manifolds
Gs ewg up pipe
Protune


Just unsure about the fuel rails and fpr

no, rails or fpr are not required for the fuel pump and injector upgrade. Some do rails, but it seems like most don't- myself included (this level/stock turbo). Are you going to run 93 on the fp green or E85? I wonder if running 93 if you'd use less IDC than say VF52 on E85? Like already stated, rails aren't required to use those parts- but may be a good idea depending on your turbo size and fueling down the road. A good tuner will know for sure.

Did you have any fuel "stumble" problems that I have found common in the forums for the GRs?

So for my 2011 wrx, if I just get the dw65 fuel pump kit and injectors (id1000 or fic 1100cc). I should have no problem with the fuel delivery?

I did not, but I had the car tuned by a pro tuner (Mike Botti) back in April about a week after doing the fuel injectors.

Just those upgrades along do not require fuel rails. I've heard of it being a good idea, but I think it was because of a "down the road" kind of outlook. I can say this for sure- if you run a stock turbo on pump, you will absolutely not need rails, also a stock turbo on E85 you still will not NEED rails (some do, most don't). I am not sure on the FP green along with pump gas if you'd need them, I would think you'd still be using less fuel than say a VF52 on E85, but this is a question best suited to a professional tuner

If you were going to consider the FP green AND E85 down the line, I'd think it would be a good idea to get out of the way now, but hell- I could still be wrong! Maybe stock rails are good enough then even? I plan on changing them when I go to a 1.5 or 2.5xtr, but I plan on E85 as well

Well looks like I can save some money for this winter of mods!

Me (13sti) and my friend (12wrx) both have fic 1100cc inj, dw65c fp and tuner by the same tuner. I had the stumble after going from e85 back to pump gas. He did not. After trying many after market stumble fixes, none seen to work. Lucas concepts was the best. I just got my car back after having the aeromotive fuel rail kit installed and the stumble is gone.

Next time, read the sticky threads BEFORE posting. Your repeating a question that has been asked here since the Civil War has diluted our search engine.
