question about turbocharging a 2.5

[cardboardpimp420]

ive got all the parts i need to turbocharge my 2.5 avenger...i was wondering if anyone knows if i were to put this on would the computer recognize the extra air coming in and in response give it more fuel or is there any programing involved?


-thanks, ryan

Um yea...
I'm pretty sure the computer would recognize it but I don't think it would know exactly what to do with it, it may even see it as a problem and set off the MIL, but I'm pretty sure it would work to a degree.
Not 100% sure though just giving my thoughts.

i would definately look into getting a new ECU, or get yours reprogrammed. im pretty sure that for every car out there that runs boost that wasnt originally designed for boost, will have problems. This is because the stock ECU was meant only to read gains that were acheivable under stock conditions, so a stock avenger will utilize the intake vaccumm, where the car will simply suck in air on its own. if you turbo the thing, air is being forced into the intake chamber at alarming rates, which would cause readings to go off the charts. Therefore, the ECU will have to guess on the A/F ratios, etc., which could leave your car injecting lean or rough mixture. im sure you could do this for a while, but soon or later the car's cat converter may melt out internally, if the mixture is too lean, causing unburned fuel to hit the chambers of the CC, or the engine may just quit on ya, not acheiving enough fuel to the mixture. if your going big into boost, everyone always says to get bigger injectors, because more air in the intake chamber requires more fuel to burn, resulting in more HP, etc etc etc.. you know the story.

but this is in my opinion, you do what you want.

by the way, what turbo exhaust manifold did you get? i just got a 97 avenger ES this afternoon, im really likin' it, but i can already tell that the beast needs to be turbo'd, its got the potential.

ive decide to scrap that project cause it was only going to be temporary anyway i just wanted to know if i would have to spend any money on it and since i would its a no go...im actually in the process of rebuilding a Twin Turbo DOHC 3.0 from a 3000gt that i plan on dropping in there. Thats gonna be a project in its self to go in cause the engine actually faces the opposite way. I will have to weld mounts into the car and im lookin for an AWD eclipse rear end to put in there to make the car AWD.

im excited to get all of this done but its probably gonna be another year til i aquire everything i need but it will all be worth it in the end
