thats a bit dangerous not upgrading your injectors.

 

[262crewtsi]

Im no expert but im preaty sure u would at least upgrade your injector to some 550 cc or 650 cc for a 16g or b16g evo3

u mean 450s are too small for big16g?, i know ppl that have big 16g turbos and they have no SAFC but if they do have bigger injectors they would be wasting tons of gas becuz the ecu cant control them, they have no safc with a big 16g witch mean they have stock 450s????

any1.

don't go over about 14psi. You'll run into fuel cut after that. I'm guessing you don't want an afc because your scared to tune. If your looking to make power without tuning I'd get a set of evo 560's and a jeff o chip burned for your setup.

ok uhm... so i still need safc at the end of the day, the ecu dont know how to control bigger than 450's.

what turbo should i put withc replaces the 14b without touching the stock injectors, and staying away from safc,????

man i ran 16pnds of boost on a 14b??? this makes no sense. no safc stock injectors

 

[tristanmb81]

what numbers are they pushing with their b16g and how many pounds of boost. i see no point on upgrading to a 20g if you are just going to be boosting 14lbs.

 

[bastarddsm]

Any turbo will work, just don't go over 14psi. However anything larger than a 16giish turbo and you will be losing performance. Heed my above post and you will be a happy young lad.

its not worth it bcuz i was going to run 25pnds with 750s nd an safc



i wanna keep stock 450's with no afc.

but this makes no sense.. my friend had a 1g dsm a evo3 big16g he was boostin 20psi, no problem and im a million % sure he had no safc. .... he coulnt of had bigger injectors.


why would i get fuel cut at 14psi???

 

[tristanmb81]

i would not go any bigger than 16g if you want to remain stock.

 

[tristanmb81]

hot air and not enough fuel could cause some serious engine failures. however, you should try it then let us know what happens?

witch 16g evo, big 16g witch...

or any16g is stock.

 

[tristanmb81]

i would go with the e16g, and what boost levels are you trying to achieve?

i want to run at least close to 20 with stock injectors. my friend did it n had no prob,.

 

[2of9]

i think you'd reach fuel cut. good luck?

 

[tristanmb81]

all cars will behave differently, even if you have the same mods as everyone else. i think that is a little too much for a 450. i could be wrong?

but if i put bigger injectors i need SAFC to control my injectors after... and if thats the case #### 16g im keeping my 20g n gettn the injectors n the fking safc.. this is bullshit. i ran 16pnds on a 14b with everything stock....

but remember playing with too much boost could lead to knocks and detonation. your intercooler can only keep the air temps down at to some point. it is on ongoing battle to achieve good horsepower.

a 16g will work fine but idk about running 20 lbs of boost... might run into blowing up your motor or head gasket for sure unless you got that all replace where its not stock. But give it a try but doesnt sound to safe runing 20 psi of boost with stock injectors might run too lean on your air to fuel

on a evo3 16g how much PSI is safe on my engine and at what psi the can the stock injectors handle up to 14? 15?

 

[qendrim]

CAN I DO THIS?

stock 450's
no safc
evo3 16g
walbro 255lhp
and run 14 to 16pnds of safe boost?

After reading this thread I now know why people that are making power stop posting on forums. I have a DSMLink log (somewhere on the laptop) of a stock 14b @ 18 psi with stock 450cc injectors and there @ 123%, @ 21 psi the IDC was at 167%... You might was well just run your car into a pole if you think your going to run 20 psi on ANY turbo with stock injectors.
