I have a standard 50-150 nx wet kit now. I have a 200 auto camaro with all the bolt-on, stall 3600 3.73 and built 4l60e.

I know the 4l60e is the weak point so that is why i am looking into a progressive shot that starts at 75 and progresses to 125 or so.

Also i know that the 3-4 clutch pack is the weak point in the tranny, so adding a window switch that would shut the nitrous off right before the shift may help prolong the tranny life.

How do i do this? I don't know a whole lot about nitrous switches and computer mods for it.

What modules or switches do i need?and will the work with the kit i have now or should i buy an entire different kit?

 

A window switch won't matter on that since as it drops in RPMs between shifts it'll spray again because it'll be back "in the window".

 

It's not going to be automatic, but you could wire in a push button kill switch, kinda like how guys with trans-brakes wire an extra relay that triggers off the trans-brake button.
I did this since my window switch did not have an option for locking out first gear.
