Modify the walbro 255 and it will handle the power much easier.
While you're in there replace the fuel sock part # 125-147. its about
a $15 shipped i believe i get them for.
on 94oct, id go with the 1100CC fic high-z. contact me for pricing.
If you have everything ported, nice big cams, and nothing is left unmodded then it is possible to touch 500 on 94. If you have a high comp 2.0L that helps a lot.
key power makers are: o2 dump, big cams, very ported out intake mani, 3 port & mbc (both), good FMIC, etc. on 94oct, the FMIC is very important.
don't forget speed density with a big 4" sd intake also. that alone will net another 12-15whp by itself. then when you really go to crank the boost the gains keep going up
and up. the more boost you run, the more additional power you will free up.

With dual walbro system the 1100cc will probably get around 600 on e85 pushing them in the 90% idc.
380whp Mustang is my goal - '04 Evo
Will have the following:
- GSC S1 cams
- CXRacing FMIC w/piping
- Perrin Intake
- Grimmspeed MBC
- 3" turbo back
- PnP'ed stock ex. mani
- PnC'ed stock VIII 9.8 turbo
- Walbro 255
- 91-93 pump gas (mostly 93)
I was thinking PTE 1000cc? Those seem to be very common, I just want to make sure they will be enough. Honestly I just want 350whp Mustang, anything more and it'll be extra goodness.

They will be more then enough. I would mod the walbro just to know you have more muscle with the fuel pump though when it comes time to put it to work.
Thanks for the reply! Motor is a stock compression built 2.0 Ive got a ported skunk 2 intake mani and tb, ets 3.5" I/C and piping, GSC S2 cams, hallman MBC, tubular mani and o2 dump and am currently switching to SD. I currently have PTE 1000cc injectors. Do you think they could limit me on pump gas or should I upgrade to the FIC 1100's to be safe? Im going to look into the walbro 255 mod and I will order a replacement sock.
Ya replacing the sock helps a lot. I recommend replacing that every 2 years or sooner.
I haven't researched this enough yet as I thought just dropping in the 255 would be enough - but what do you mean by "modding the 255"? Is there a link or thread you could point me at so I can read up on it?
Thanks a lot man! Not very often shops/tuners give out free advice unless you're personal friends with them

Ya id recommend FIC. i sell every brand injector, but i really try to push FIC because FIC's customer service is by far the best!
FIC's best mid range performing injectors to date i would say is the 1100CC high-z injector set.
An 850cc would not be bad option if you want to keep cost down though
Under 350whp on a dynojet the stock injectors can handle though easily.

the relief valve on the left on the pump gets pushed in with a bunch and a hammer carefully. this allows the pump to flow a lot more fuel at higher fuel pressures.if you're scared to do it yourself i offer the service also, or will sell you a new pump with it already done to it.
I suspect with those mods listed that I won't be too much past the 350whp. I don't intend on doing a different turbo then the one I listed. So should I just rock the stock injectors and monitor duty cycle on them? I don't want to go for a tune and find out my injectors are holding me back. I want to get it tuned once and leave it alone.
Thanks for the feedback.
Thanks for the feedback.
I also sell the injectors to the customer for a good price as well. so win/win for the customer.
Those will work well and are a good mid range size injectors that suite most peoples setup.
You're welcome!
Im not sure what a aeromotive 340 is capable of with a bigger feed line, better efficient fuel rail and different base fuel pressure.
you may want to just go straight to a dual walbro or try the 416lph walbro hard wired + run a larger feed.
I can tell you with stock feedlines with something like a br double pumper you wont run out of fuel until 800whp though on a dynojet, which would be roughly 696whp on a mustang like fftec's .
I have a ix with tbe, licp, mbc, air filter, and self tune 24 psi. Virtual dyno says I'm making 310. I'd like to tune for e85. Was thinking about fic 1050 low z. I may upgrade to a maperformace ef2 one day. What injectors do you recommend.
https://www.evolutionm.net/forums/ev...s-272-e85.html
this customer has FIC 1050cc injectors, and modified his walbro 255 fuel pump.
here is the graph in case you dont want to read through the first post.

You will be fine until about 480WHP dynojet on e85 with your current fuel setup + modding the walbro 255.
I would keep the injectors until you're ready to swap out then go for a 1450cc or something around that size.
If you throw a double pumper in the car, then the 1050cc inj should get you somewhere around estimate, id say 550 maybe tops on e85.

Current setup on my 04 evo 8:
evo 9 turbo
Tomei 270 procams
Kiggly beehive springs
Shearer o2 dump
BR fmic
BR uicp/licp
BR small battery setup
BR TBE
walbro 255
hallman pro rx mbc
tial qr bov
comp stage 3.5 clutch
fortune auto 500 coilovers
Dynoed on MD 363whp/364wtq @25psi with parts listed above
I will be installing:
FP black DBB
FIC 1250cc
Full Race stock replacement manifold
Shep trans ultimate ratio, 4.11 FD
Spoolinup COP
With the addition of these parts, how much will the 1250's get me with a modded 255 on 93 and E85? I am wondering if I went too small on injectors with the turbo. Thanks in advance.

On 93, thats enough injector and pump for around 550whp~ not sure on the exact number.
No the 1250cc is a decent size and with a double pumper they will support around 600whp (dynojet).
