I have mostly bolt ons now I'm looking at getting the zex kit that does a 75 to 150 shot. I have an m6 so I know I'll need a window switch. Ive read Ill need colder plugs and the timing needs adjusted? I didn't know if I needed the purge kit and the bottle heater right away . Im just trying to get an idea on the total cost. its not just the cost of the nitrous kit im finding out

 

If I was you I would just call NitrousOutlet and talk to chris. Or call one of the other sponsers. They would make you a pkg deal.

I would go with a different kit then ZEX there is plenty of sponsors on here with sweet kits.
This is what you need.
I would get a good window switch that has a RPM and a progressive.around $150 to $225.00
Good nitrous kit, Nitrousoutlet,HSW around $450.00 to $550.00
bottle heater around $100.00
purge. around $50.00
You maybe able to pick up the heater and purge on here in the forsale section.
Then you need at least #7 NGK plugs and someone to tune your car for nitrous.
Good luck let me know if you need anything else

 

thanks for the help.

 

You can run a system without a purge or bottle heater but they are nice to have. I'd suggest getting a bottle heater over a purge at first because is run off of bottle pressure.
