I am forced to upgrade my fuel injectors but im very ignorant about it. I have a stock SR20det with a stock T25 turbo, lets just say its all stocked. i have a problem with my fuel injectors one or two are acting up haven't checked them that good but i know its an injector problem. Stock injectors are 370 cc what i want to do is upgrade them like add a piggy back for my computer or can i just get my computer re chipped. Like i said I'm very ignorant about this.

why would you get bigger injectors?? Take a multi meter and check how many ohms of resistance going across each injector to find the bad one and replace it. You only need to upgrade injectors if your planning on getting more power out of your motor.

with a piggy back you cant go bigger then 50% more of your stock injectors. so no bigger then 555cc injectors.

also there is no reason to upgrade your injectors unless you need them a stock motor does not need to upgrade stock injectors at all even at the turbos max efficiancy 15psi my AFR was fine with stock injectors.

so basicly get stock injectors and you will be fine they can be had for $70-100 on local forums

I actually thought that if one of the injectors was bad then i had to change them all so that they all can be at the same condition rather than having one newer than the other and i couldn't find any 370cc other than stock, thx for the response.
