I've got the same kit and love it! I wouldn't pick another one if I had it do over again. You may want to look at the HSW Microedge controller for a lot of added safety.

Wow, that looks like a nice kit.

Do these kits require an aftermarket TB?

So what's the advantage of running a 90mm over the 78mm?

will soon be getting a fast 90 yes, i know doin it backwards but i couldnt pass up that deal...

I beeen looking at the HSW website and like their ash tray switch, but it has two accesory switches, i would think a bottle heater for one but what would the second one be? Also i want a nitrous pressure guage in my a-pillar how hard will that be?

You can use the second one for anything you'd like. Line lock, bottle opener (use the switch that comes with the opener kit in place) are just a few examples.

Gauges are pretty straight forward. I would recommend using the electric gauges over the mechanical.

thanks

I agree...It will cost a little bit more, but it's better than having another 20ft line of nitrous going through your car...wasteful!
