Best injector choice for bp?

[dailordasailor]

Was planning to get gtx injectors but another member said may not be enough. What I have:
-t25 from eclipse
-gtx ecu
-eBay t3 mani
-91 escort gt

concern was if the 330cc would work well with t25 on low boost (about 8 or 10 psi). If think not, what would be best option? Also will I need better fuel pump? Anything else?
Thanks

The T25 is not a huge turbo so the 330ccs should be enough for it at the boost you mentioned.

Before you will run out of injector, you will hit a boost cut if using the GTX ECU anyways so that is a nice safety net telling you you are getting close to system limitations.

Also, I would not run injectors that are different than what the stock ECU is programmed for unless you choose some sort of engine management system.

I've had a Walbro from the get-go in my car but people have kept the stock pump while staying conservative with boost.

I would also consider a wideband sensor/gauge if you're going to be playing with injectors or the fuel system at all.

Plan to run gtx ecu for now. Building a motor on side with plans of megasquirt. And know will need a wideband but just want to make sure before purchase injectors if they'll work. Like idea of gtx ecu/inectors because designed for eachother.

Any othe opinions? So far looking like 330cc it is

the ecu is only as accurate as the afm..... no matter the injectors.... stock gtx ecu, with bigger injectors and adjusted afm can get past the boost cut to an extent...


boost cut is just the end of the range of the afm, put in bigger injectors and adjust it, and you can move on past it...

hell theres guys in nz who thread a screw into the afm so the door doesnt hit that spot on the board...

Killing me^ lol. Just want someone to say "do this ..." lol

[yunvmyegt]

i said try them as long as you got a wideband...lol....

[dailordasailor]

Damn it... Lol. Leaning towards gtx injectors... I'll run even lower boost if find it to be an issue. It's a temporary thing until summer when I can afford to build the motor right. Want to be able to take to Carlisle in may on setup I'm tryig to peice together now. Of course a AAA card will be purchased

Lol how do you double post a hour later. Anyway the 330cc injectors are the F2T injectors. The GTX injectors are 330cc on the gtx fpr but on a stock Escort GT fpr they are 360ccs. So if you want a little extra room then go for the gtx injectors but you could also go for the 330ccs and get an adjustable fpr and raise the fuel pressure if you need to.

[dailordasailor]

iPhone driving.. Lol. And interesting info. Guess I'll look more deeply at the gtx injectors then... Will I need a new fuel pump?

[yunvmyegt]

even then 10 psi increase is only good for about another what 25 ish cc's of flow going off a few calulators ive used... so 330s would be 355s, and 360s are like 385... even at 60 lbs the 330s would only do about 380ish...

[dailordasailor]

What?^ lol. Above my head lol. Bad for me or good? Lol

[yunvmyegt]

if the turbos really that small, just get them for something to start off with and get it running.

[dailordasailor]

Thats what it's looking like.. 330cc and a wideband. What else is "necisary"? Hoping to avoid fuel pump for now If I can financially but if neccisary...

[Turpro]

Technically you don't need one but its good to have. My car just felt smoother when I put the walbro in. Could've been just having a new one in or the added support who knows.

Just for reference my bud is running f2t 330s on his 5psi t3 setup.

Good book to buy is maximum boost by coorky bell. It schools you on turnos and ****
