NOS (Nitrous Oxide) in the X-Trail (QR25DE)
Hi Guys,
Some of us on this board are interested in all of the available performance modifications which can be done to the exy and this is one of them which I thought deserves a new thread (thanks for the tip Brett)
Nitrous Oxide or NOS as is commonly referred to by car enthusiasts has been successfully used in the exy with the QR25DE engine. (Terranismo was running NOS- wet system with 60 shot when he had his xtrail)
Now before we go into the details and if like me, you're completely new to the NOS modification idea, let's start with an overview of what this system actually is and what it does to the car.
I found a great source of information explaining the NOS set-up in detail:
Exploring Nitrous Part 1
Exploring Nitrous Part 2
Exploring Nitrous Part 3
The power gains as a result of this mod are enormous as the above overview suggests and this has been backed-up by the actual users as well.
The reality however is that our QR25DE engine can only be safely tuned to a maximum of 275-280HP (or 208KW) before things can break apart in the engine and serious damage is caused!
So, with this in mind, there is some serious consideration and research needs to be done before this mod is added to the list.
Please share your thoughts, links and any other sources that relate to the use of NOS in the QR25DE engine in particular and we can assess them together as we go along.
HERE is one of those sources showing the NOS set-up in the Nissan Altima with the same engine as ours.

Thanks Matt. I didn't know this and I guess with this in mind the constant flow set-up is not an option.
HERE is a good article describing the legality of NOS coming from an Aussie manufacturer.
QLD and WA guys are out of this modification unfortunately LOL

Hiding the bottle or painting it is the last of my concerns about this mod, as the exy has plenty of spaces where this can be done, but keeping in mind that our forum does NOT support any illegal set-ups, we won't go through that here
I like the chrome touch-up idea though. hehehehe
