Just call your local speed shops/tuners, they usually have it. They have large bottles of it and they hook your small bottle to it and fill-er-up..It run's $3-$4 a pound.

 

I see that you have a Zex Nitrous system installed. Do you have any installation tips?

 

It is a pretty easy install...The directions are good, just take your time. I spent about 6 hours on it as to make everything clean. I would recommend a Zex purge kit, bottle heater and a nitrous pressure gauge to go along with it. Do it all at once while your at it to make for a nice clean install.

If you run into any problem's just PM me and I'll give you a hand. It is a good kit and you will have fun with it.

BTW: grab yourself a set of autolight HT0 spark plugs to stay safe and plan on getting a dyno tune to ensure safety & performance as well...This is how mod's get expensive on these dam Ponies. lol

 

I see that Brenspeed.com has the Zex kit for $569

Not sure what the shipping charges are but $569 sounds quite good.

 

That's the basic kit, I bought my system from Breenspeed as well...You will still need the other item's I listed. I forgot to add the blow down tube which will be needed if you go to the track (a requirement at most track's). You can find this stuff on Zex's web-site. A good way to buy it is the "tuner" package. At the bear minimum you will want to have a purge, plugs and a tune...IMO

Go here and click on "Racers tuning kit"....There is most of what you will need in addition to the basic system from Breenspeed. It is so much easier to do it all at once while you have everything apart rather than going back and adding stuff on latter.

I think all items from Brenspeed come with free shipping.

 

Did you notice a difference after installing the UD pulleys? I've been debating whether to do UD pulleys or 4.10s first.

 

I can't say I personally noticed much difference with the Buttometer but a dyno might show some difference.

What I did notice is that the A/C didn't work quite as well at idle.

I fixed that by increasing the Idle speeds using SCT's ExtremeTune software.
