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.
