LS2 nitrous question
I have an LS2 C6 Full Bolt ons and I'm going on a nitrous unit, it's a safe system. My question is: do I have to change the fuel pump? I'm doing a 150 shot, I'm changing injectors to 52lbs and also buying a Wideband for it. Do I really have to change the fuel pump?

Famous last works.
Hence Nos works buy reducing the amount of nitrogen in the air mix, increasing the oxygen amount in the air mix for a hotter and more powerful burn, which translates to more heat to the piston and rings. OEM LS rings are gapped at .006", and with the added heat of the NOS burn, very easy for the rings to go to zero gap, bind on the cylinder walls, and snap the heads of the pistons off.
So before you start thinking NOS, pull the pistons and gap the rings at least at .028", so they have room to heat expand on the Nos burn so they don't go to zero gap to take out the motor.

I would ask the question over in the forced injection/nitrous forum. There are some dealers and installers over there and someone will have an answer for you.
