Could anybody tell me what the stock size injectors are or where I could find this information. Thanks.

 

240cc.

 

thanks, what would be the safest size injector to upgrade to?

 

it depends on your mod but 340CC to 400CC should be more than enough unless you are going to spend extreme amount of money into the car!!!

 

do you know if the injector fittings are the same as in the 2.4L MIVEC?

 

hmmm not sure but you can fit dsm injectors and i heard that you can even fit the current RX-8 injectors.. ask RRM i am sure they can tell you everything about it!!

 

You can't just throw injectors in your car because they fit. As much as I love repost threads, here's the short answer:

DSM injectors may physically fit, but they are low impedence (peak and hold) injectors, and your car is designed to use high impedence (saturated) injectors. I BELIEVE a person or two has managed to use the low imp without catastrophic failure, but that could just be my memory fading. What would benefit you the most is searching...a lot. And reading...a lot. Without getting into the differences of peak and hold and saturated injectors, you don't want to use low imp in a car designed for high imp unless you have the proper supporting equipment.

All this being said, assuming you do grab some high impedence injectors that FIT, your stock ECU will not be able to control them accurately without some sort of assistance. I don't know the limitations and capabilities of piggyback computers very well, but needless to say that would be the very least you'd likely need to change the injector size.

Unless your car is using forced induction, aggressive cam timing or something else fairly outrageous, there is really no benefit to adding larger injectors anyway. Think, and more importantly read, carefully before seriously considering such a potentially large investment. From the mods you have listed in your sig, I wouldn't let the idea cross my mind again anytime soon.

 

with the intake i have, exhaust im putting on and the proper fuel upgrades, pump, lines, regulator ect..., upgrading to those injectors shouldn't be problem as long as i had fuel mapping, that was explained to me earlier. but what i was also informed of is to put that kind of money into upgrading a 2.4 L MIVEC which i plan on dropping into my Lancer. i was only curious to know if the fittings were the same.

 

Upgrading the injectors isn't a problem, so much as it's unecessary. That's my point. It's not a question of ability to flow extra fuel so much as whether you need the extra fuel. I can't see a reason why you would need extra fuel, but if that's where you want to put your money...it's your car. I wouldn't go more than 300cc's with a setup like that though.
