will the bottle fit in the compartment behind the driver's seat?

Just pull off the panel with a flathead screwdriver. Might be hard to get it setup there without first ripping out all the rear interior or something...

 

it would b a pita to keep takin it out to get it filled, too.

 

I've heard it would, but that would just be a pain in the ***. I have my in place of the spare, you still can use the back somewhat, just not as much as before.

My switch is in the lower compartment of the metra kit at the back, full stealth.

 

I mounted my bottle in the compartment behind the driver seat. It's really not that tough to get in and out of there as long as you remove the sub plate. My bottle actually hangs in there. I mounted the brackets up above for fear of drilling holes in the gas tank below. You will need to remove some of the interior to do this but it's not too tough, just try not to snap the clips.

 

I think the biggest challenge is getting the bottle mounted sturdy and to have the blow down tube located correctly so that you pass tech at the track.

Putting it instead of the spare tire will work but I want to keep the tire. The best location I figured so far is to put it on in between the driver seat and the rear strut bar and then route a nitrous line through the groment instead of the blow down tube, otherwise you need to make a custom tube since it has to go outside the car and I don't want to drill another hole

 

If you bolt the bottle onto the carpet, will it pass tech inspection?

 

no

the rules state that it needs to be permantly bolted onto the car.
Most tracks I've been to have double checked that and turn people away that didn't foolow that rule since the bottle otherwise could come loose in a crash and kill you

 

You can always get a smaller 5 lbs bottle, and put it behind the panel where the bose sub would go (if you do not have bose sub). Also, you can put it in the glove box behind the passenger seat. If you remove all the paneling there in the middle of the car, behind the seats, there is actually quite a bit of room under it all. It would be a big pain to keep removing panels to get to the bottle all the time though, but you can do it.
also, a smaller bottle, or a daisy chain of sneaky pete style bottles would fit in the rear spare tire well.
there might be enough room behind some of the plastic trimming in the trunk area for small sneaky pete bottles.
there are a fe options.
There are plenty of ways to hid the nitrous lines, solenoids and wires in the engine bay as well, it's really easy to hide on this car...

 

I've decided to put the bottle behind the passenger seat and before the strutbar sideways, it fits real good. I talked to NX about mounting it sideways and even though they said it's not ultimate it won't be too bad either.

 

I put mine (10lb bottle) in the glove box and at about a 25 degree angle off from the "correct" mount. It is a very tight fit with the remote opener but it sure is nice to be out of the way. I did have to remove the glovebox and now when you open the door its all bottle.

 

thats were i put mine after talking with ZEX and a few nitrous companys. the negative effects are minimal since i dont track the car anyway.
