Default Fuel Injectors

What is the difference between low impedance and High impedance...

I'm still new at fuel injection and turbos so I want to be sure to get the right parts

For a 2001 Corvette with twin 40's do I need high or low impedance injectors?

I don't think I will make more than 500 to the wheels. The motor is 100% stock and I plan on using 60# injectors and upgrading the fuel pump...

When this build is done i'm going to start building a 6.0 short block to replace the stock block. I don't want it too radicial since I daily drive the car, I just wanted more power. I chose the turbos because they are quiet vs a heads, cam and exhaust car.

I have some 60Lb injectors I will let go for $375.00 They only have dyno time. Plus they will work for your app. I can not use them I have to get bigger injector and a driver box.

These are Mototrons (spch)

High will work with your stock PCM, Low are for aftermarket PCM's.

if you are wanting no more than 500HP~ give or take a tad, some 42# or 50# would be your max you would want
