Need help choosing new fuel injectors

[Kraz25]

Have a few mods done:

GT30r Garrett Turbo
Walbro 255 Fuel Pump
Evo3 Exhaust manifold
Turbo Timer
3" Apexi turbo back exhaust
Evo 8 Front mount with all hard pipes.
AEM Wide band O2
Apexi manual Boost Controller
Greddy blow off valve.

Still have stock injectors and was wondering what size injectors would be just right?Currently running a tune on stock injectors at 12psi.Has no problems.Trying to run daily 18psi.

You should of really bought something to tune with, such as DSMlink. So I would buy DSMlink first and then buy some pretty decent size injectors, as most will get hit with a boost bug. That way you won't have to upgrade again hopefully.

 

[Kraz25]

Yea I have a DSM Link 2.5

 

[grothe3297venge]

Yea I have a DSM Link 2.5

Yeah you didn't say that or have it in your profile... well then go nuts with any size that your heart desires since you can tune for it with link.. Again, go big because as most have, you will get hit with a boost bug and want more. So just buy bigger ones and be done with them.

I would go with the fic 1050 or 1150's the low z, biggest injector for low z and best spray pattern. I have the 1050's now and had 850's, so just buy once and get alittle bigger. Actually looks like they sell up to 1650's in low z now that's sick!!

yeah i was going to say FIC but....

I haven't had any problems with my FIC's...

Go all out 2150 hi-Z, inwish i had never bought my pte 1000s.

The bigger the low-z injector the worse they will idle/cruise. If you're going past 1200cc on a stock ECU it might be time to think about switching to a high-z injector.

Go crazy 2150

 

[troubleshoot]

850's should be fine for your set up but id go bigger if you want some room to grow, especially if you ever plan to run e85. Definitely go with a low impedance injector like fic blue max. From what I understand, low impedance injectors respond faster. Also, do you have an AFPR? If not, does your car stall out when the rpm's drop fast? My 255 over ran the stock FPR and it did that until I installed my AFPR.

Just get 1000cc if running pump gas if going for e85 go bigger.

 

[Jon91TSi]

550cc injectors will handle up to 25 psi all day long. But I'd go with 1000s or something like that so your ready for e85 or more mods that require lots of fuel

You can't be serious....WTF

strike 1 for you.

 

[Calan]

Yea I have a DSM Link 2.5

In that case, the first mod I would recommend is an upgrade to Link V3. Then get the biggest set of FIC injectors you can afford.

 

[Boostdriven]

Get a set of new or used pte 1000cc injectors. I've ran those injectors for a long time with my HX40 and made a little over 500 awhp with duty cycle around 85%. I found those injectors to be user friendly, they had good idle and cruise. They will be more then enough for you and leave you some room to go with a bigger turbo down the road.

And like Calan said, you should upgrade to Link V3, it will make your tuning life a little easier.

Pte 1000s are great injectors but i totally agree: Go hi resistance so you can delete the resistor pack and go a minimum of 1600cc. It removes a component so you dont have to worry about it being a failure point in the future plus you can run e85 with really big injectors.

Just fyi, i strongly suggest against trying to go cheap and buying bosch 1600s like i did. They are wacky and have a resistance of about 5ohms. Thats causes problems for cruise tuning. WOT is great but cruise, on my setup, sees a lot of jumping in the combined ft. On my old ptes this was never ever a problem

 

[troubleshoot]

Id like to retract my previous statement . Did a little reading and hi z is the way to go. I guess low z was more reliable in the past but after reading the FAQ on FIC, s website im sold on hi z. My Talon has been hibernating for quite a while so im way behind the times I huess .

FWIW, I got my 2150's to idle and cruise just about as good as a set of 450's. I had a hell of a time getting low-z 1550's to even have acceptable street manners, and eventually moved on because I was having such a hard time with them. I scored my 2150's for $550 brand new
