Hey....whats the most boost that a stock srt4 turbo can handle?

 

someone chime in if im wrong, but i would say it could safelyhit about 19psi with a diff wga. after that id say it would be madd inefficient. dont forget that stock 04/05 injectors (03 stage 1)are only 577cc/min.
do you have a wideband? if not youll need one if your going to start tinkering with things so you dont go too lean.

 

iight thanks....i was told i didnt need a wideband...and that i can tune my fuel from a safc..but i dont know how true that is...and i was going with the stock srt injectors....if i need bigger ones....let me know....

 

you do need a wideband unless you don't care about your motor.

on the stock fuel system the max is 17psi or so, with fuel 19psi.

 

stage 2 injectors, and 19 will be fine. with a full stage 2, i've run 21 psi, and the leanest i saw was about 10.5:1. usually it was closer to mid nines.

 

running more than 19 psi on the stock turbo is useless, it's out of its efficency range. that's why i said 19psi, the fuel can support more but the turbo isn't capable ot making more power.

 

thanks for the input everyone...i wonder how much of a difference it will be on a 2.0 dohc engine, since the displacement is a bit different....wasnt planning on pushing it more than 17-18psi. so will the stock srt injectors be enough for that, or should i get better ones?

 

i honestly have no idea. i don't know what your fuel system looks like, but i would probably suggest getting s2 injectors at the minimum.

 

welli have awalbro 255 external inline on the way...aeromotive fpr, aem fuel rail, and safc for tuning...since i need the wideband, ill get that soon also

 

let me ask a dumb question....how did you plan on tuning without a wideband?
