Well first off you'll run a dry nitrous set up. I'd recomend that you don't go over a 75 shot. The fuel systems are all the same I belive. But you'll need a rising rate fuel pressure regulator to keep from leaning out. Also get an air/fuel ratio guage so you can keep an eye on the air/fuel mix. Remember nitrous dosen't f*** up engines it is lean mixtures and stupid people who f*** up engines.

Get them Venom 2000 kit. The kit comes with on board monitoring of air/fuel. And if the fuel mixture ever goes dangerously lean, the system automatically disengages itself, so you dont damage your engine. Cost: $1200 but worth every bit of it!

You can't use a Zex kit if your car is a '99. Your fuel system is not compatible.

To get even more convoluted here, if the car is an EARLY 1999, then it will likely still have the RETURN style fuel system, which is required to run the ZEX kit. If you have a later 99, then never fear....Venom has a new kit called the VCN-1000 that interfaces with the fuel injectors to richen the fuel mix. It also interfaces with the o2 sensor to protect against rich/lean conditions. Cost? A little than the VCN-2000, the VCN-1000 will set you back about $650-$700, and you will still need good stuff like a gauge pod, rich lean indicator, bottle pressure gauge, and possibly a bottle warmer.
