i have a 2004 Saturn Ion Red-line. i recent bought a 2.8 diameter pulley for my supercharger.. im wonder if i can just put the pulley on its self or do i HAVE to change my injectors? what will happen if i don%26#039;t change them... or were could i find some cheap ones?|||You could probably get them from Jegs or Summit. I don%26#039;t recommend them without something to control the extra flow. Your gas mileage would probably become terrible without some aftermarket engine management and professional tuning. Another question would be if the rest of your fuel system was up to the task. If your fuel pump is not capable of pushing that extra flow, you will need to upgrade that, too. Before you do that, you need to check if the wires are thick enough. Higher flow pumps can use more juice. Melting a wire or popping a fuse in the middle of nowhere can leave you stranded.
What I would do is put the car on a dyno with a wideband o2 sensor (with your current setup) to see if you are running lean, and if you are, stop the dyno pull immediately and think about the fuel system upgrade. It is a large project, and not something you can bolt-on and expect to work well. Good luck.|||eBay motors.|||try your local wrecking yard.
