question can i run 17 PSI with stock fuel pump and turbo on a 98 eclipse??? without my fuel cuttin out? im at 14 now and its fine

i have a blitz BOV
full 3' exhaust and downpipe injen intake and otheer light mods...would this be ok?
and if it isnt enough fuel whats the worst that could happen or most likely?...should i use fuel injector cleaner and replace fuel filter before i up the boost as well??? ideas plz
 
The T-25 actually is out of breath at anything over 15-16psi! It will make more power but not much. You should really leave it at 15psi till you get a pump. And a logger to see if everything is ok, better to be safe than sorry.

well question..if i go with a walbro 255lph pump and im at 17 psi with no tuning that will be ok im geussing...but if i turn the boost down to 15 or something will i be gettin to much fuel??? please kinda give good answers i only know what ive read hehe...
 
It will actually make less power at anything higher than 16 psi. Leave it at 15-16 untill you get a pump. I recommend the Walbro 255lph and some 550cc's. Also, FPR and S-AFC if you have the money. Good luck. :talon: :thumb:

i heard 255 would be overkill for my t25 turbo and 190 and 550cc would be the way to go..because even if i upgrade to a 16g or a 14b i can run at 20psi with no problems...
 
y would it be overkill?, its a fuel pump, y buy a 190 thats thats going to reach its limit at well under 400hp when u can just get the right one to start with, its not like having a bigger fuel pump will make the car run any differently, its just louder
if u ever buy a good new turbo u woyuld have to throw that 190 away and get a 255 anyway, so u might as well get it now instead of wasting money
and u wolnt hit fuel cut untill about 19 psi on the t25, and contrary to what most people here say there is a big difference between 15 and 18 psi, i say this from direct expirance on my friends 2g tsi, that extra 3 or 4 psi makes all the difference on his car, his mods are about the same as urs
 
so flowing to rich wont hurt my car??? because im not upgrading injectors till later
 
Stick with the stock injectors for now and get the pump and the AFC. You can get by on that for now with the T25. The 550s would be a little better but I would wait for now until you know what turbo upgrade you're going to do. If you skip say the 16g step and go to something bigger, then you're going to need 660s anyway and you wasted your money. You're money would be better spent on getting a logger and tuning the car with the 450s than guessing on your AFC with 550s. (I bet you'll go faster too:thumb: )

Can you actually adjust (or tune) the a/f with just a logger?
 
ok so i stay with stock injectors but go to a 255 pump...do i need to have a afc or logger??? ...
 
everyone here has there own way of doing things. This is what I did. you can look at my mods, and I am running 17psi with no other fuel mods. It's fine to do. You should get a 190 or 225 lph fuel pump though to do it, just to be safe... You do not need a logger or afc to run the bigger fuel pump, but it always helps:thumb: To properly tune an afc you need a datalogger anyways.

Cirus_93TSI: First off, the 190 lph pump is way underestimated. You can still make tons of power with it, and have decent gas milage. Also, how many of us here are actually going to be making 400 hp?

:mad: Can't we all at least dream? And you mind as well go bigger to the 255 if you are gonna tune it. If you get more mods it will allow for a more diverse tuning scheme.
 
you can run as much boost as that lil t25 will put out if your willing to pay $5-6 a gallon for gas. race gas is the great equalizer in that situation.
 
400hp is reletivly easy to get if u upgrade to something like a 20g, its breaking the 500hp mark thats hard, if u stay with a little turbo like a 16g or something a 190 might cut it but how many people here are really considering not going any bigger then a 16g, most people want a 20g ora garett set up, and both would need a 255
not to say the 190 isnt a good fuel pump, but im the kind of person that doesnt like to buy the same part 2 or 3 times because i didnt get a big enough one the first time, and a 255 makes a nice little wistle that will make people turn their heads to look at ur car

The annoying noise that a walbro makes is what earned it the nickname "walmart" fuel pump. I love it when I hit my turn signal and I can hear the fuel pump's noise start cycling. Well used to be able to hear. Now, with the cams... I never hear it.

BULLSHITTTTTTT!!!
I dont care what anyone on here says a 190lph is plenty!! There is guys around here running 9's and 10's on a 190lph so dont give me that shit about it done at 400hp LOL

My roomate runs 11.7 with his 190lph and now he modddded up to the 340lph walbro but this is different hes pushing out over 700hp!!!
Anyways alot of the boys around here put on a 255lph and it flodded there cars, so i would say a 190 that is what i just ordered!!!!!

Sounds to me like someone's just pissed because they didn't get the right one. Seriously though, I don't think ppl are "flooding" their cars with a 255lph. That's rediculous. A Civic could run a 255lph stock and be fine (ok maybe not a civic...maybe Celica)

"hey terrance", "yes phillip?". "do you know what color the wind is?" FAARRTT. "oh phillip you farted!!!"


hahaha i love canadians. except when they spew complete bullshit from their pieholes. id really like to see the car that runs 9s with a 190. or even 10s for that matter. high 11s, yes. 10s or 9s, absolutely not. your a dipshit for even thinking that, let alone saying it.

Wait we need to convert this all to Canadian, duh, I mean, eh.

Ok so a 190lph in Canadian is actually a 255lph US
9's, 10's, and 11's are actually 12's, 13's and 14's US time
400hp Canadian is actually less here...a reverse conversion making it only 250hp.

So yeah, Canadians can use a 190lph for 400hp and 9's.

I was gonna go get this graph when i read that post because everyone always says the t-25 runs out of breath at 16psi so it's pointless to run more boost. It may not hold that to redline but it definitly helps regardless. I ran 18psi on mine and I could tell a big difference over 15psi.

On the subject though you'll be fine running 17psi without feul mods. It's safer to have them but IMO I don't think the t-25 will out flow the stock feul system. If it does it won't be at 17psi. You'll probably hit feul cut before out flow the stock feul system aslo. The only down side of running higher boost is that it'll kill your turbo much quicker. Good luck

Correct. Remember fuel requirement increases exponentially as rpm increases. At redline the T25 won't be making more than 10-12 psi. At lower rpms the fuel requirement is much less.
 
well so many mixed opinions that the dyno graph def cleared up..for one im gonna push this t25 to the max because ill only be usin it for a short time before the upgrade since my car sits all winter :)...everyone sais i dont need a fuel pump but EVERYONE is recommending a upgrade to be safe...when u mean safe what exactly hapens? does my motor blow from no fuel? or do i just stall...and i cant find a f'in 190lph pump all i can find is walbro 255's secondly if anyone has any intercooler piping for my 98 eclipse let me know...because this stock shit isnt workin...im plannin on cleanin my intercooler tomarrow i hope its as easy as the website makes it sound..
replys plz
thank you everynoe
