If i install a nitro kit on a stock 4.6 what would be a good shot without damaging the engine? Oh the engine has 90,086 miles on it. Maybe a 50-75 shot? I ask cause a freind has a kit that he is willing to trade me. a dry kit i think. any help would be appreciated.

75 would be good. upgrade your fuel pump and possibly your injectors too. depends what kit you use

i'd at least upgrade the pump even with the 75 shot. at 90k that pump might be getting a little tired anyway. add nitrous to the equation and u might lean it out and blow it up. $100 fuel pump is much cheaper than a new engine

zex dry kit is the easiest to use and easiest to install. i ran that in my thunderbirds. currently in my cobra i run a dynotune kit. requires more tuning and take a lot longer to install

I am no expert, but the ZEX DRY KIT seems to be the way to go.

Q: What is the difference between a "wet" nitrous kit and a "dry" nitrous kit?
A: A wet nitrous kit mixes nitrous and enrichment fuel by means of an injector nozzle that is mounted before the throttle body. This mixture is then drawn into the engine through the throttle body and intake manifold. A "dry" nitrous kit injects only nitrous with it’s injector while at the same time, increasing the engine’s fuel rail pressure to feed enrichment fuel through the engine’s own injectors.

Q: What is better, a "wet" or "dry" kit?
A: It all depends on the application. A "wet" kit is ideal for both normally aspirated applications as well as forced induction applications. It can require a little bit more installation time than a "dry" kit, but is easier to tune if greater than stock HP settings are to be experimented with. A "dry" kit is excellent for normally aspirated combinations that have a return style fuel system. They are very easy to install and are a great "first time" nitrous system. It is not recommended that "dry" systems be used on forced induction engines.


You will want a pressure guage

Bottle Heater

New Fuel Pump from http://supercoupeperformance.com/default.aspx
And possibly injectors. If you dont have a chip, get one.

Check around. Quite a few guys are using it.
BTW, use the sellers here for the pump and injectors if you can.

This is my winter mod for my LX, along with a bigger MAF.

YOu guys think it is possible to put any NOS into my T-bird. ITs got a 146k and I'm worried the engine would just blow up (same reason I don't put a supercharger on it).
