I just got a used Noszle kit from my friend that had it on his 4.6 2V mustang. I am installing it on my 1995 Lincoln Mark VIII. So far I have the nitrous line run into the interior, and I removed the schrader valve from the fuel rail and ran my fuel line to the kit before the regulator. All I have left to do is run my wires, and plug the fuel injectors into the NOSzle injectors. I have to come up with a way to bolt the fuel rail to the motor properly also.
I will take pictures next weekend when i get back home, and will let you guys know how it goes. So far it looks like it should work on the 4v no problem.
