Im stock turbo basic bolt ons and i purchased an AEM 320 fuel pump i want to know what are the best injectors to purchase.

 

Check out the new ID1700. They were actually designed with corrosion resistant internals to use E85 (or any fuel for that matter) forever. I personally run FIC2150's because I never wanted to buy another set of injectors again, but ID 1700's would probably outlast them in terms of E85 compatibility. Go for ID1300's if you don't plan on making more than 550hp, this will make it easier for the tuner to achieve consistent AFR's.

 

Stock turbo, get 1000 or 1100cc injector's, Fuel Injector Clinic or Injector Dynamics are who you should be looking at for brands. No need to run injectors that are way to big. Also, those AEM fuel pumps aren't that great. A stock turbo only needs a walbro 255, I suggest going that route.

 

Fic 1450 bluemax

 

I think the OP needs to be more clear. Stock turbo FOR NOW and has realistic plans in the short term to upgrade? There must be more planned to throw a 320 pump at the car and then ask about injectors. Otherwise what we already have is a mismatch, let's not make it worse by suggesting we know what he needs. Hey OP - clear up your goals and timeframe so we can suggest a good path.

 

I believe they were discontinued.
FIC1650cc are very nice and drive like stock.

 

Can always buy used and send them to fic for a refresh.

 

I would agree with this and would add that the 1300/1700 both have corrosion resistant internals and are designed specifically by Bosch for ID. Most injectors are made by Bosch and use modified heads. I've had 1300's @500whp and they drove perfectly . I outgrew them to 1700's and those drive nice as well.

Any injector is going to flow well at WOT, its the other conditions where a nice injector makes a difference. Idle, part throttle, fuel mileage etc. Now, since you are on stock ecu get with whoever is going to tune your car and ask them what they use. Most likely they already have base maps for popular injectors to save themselves time and a good starting point. A good tuner will still look and adjust fuel trims so any (good) injector can still be used.
Here is a video that goes into further detail.



If you only want to make 500whp on Ethanol then ID1300's would get my vote. If you think you are going to make more later you could by 1000s/1150's right now and then 1700's later.

The most important thing to keep in mind IMO is having a low/mid range fun street car that drives as close to stock as possible. Huge injectors,turbos,cams effect driveabilty to an extent.
