you mean the gauges? i dont think youll need anything more than nitrous pressure. it shudnt have any effect on the oil temp or pressure i dont think. wudnt be a bad idea to get those both though just because they are nice to have

 

If you have the I4 you would be safe to run a 75 wet (NX kit) and if you have the v6 I would run a 120 or 150 direct port (NOS kit) but what ever you decide make sure you change out the plugs try a BKR7E NGK plug.

 

But before you start buying do some reaserch on this type of stuff. You'll save yourself money in the end being able to fix small things. Also then you will understand what the performance shop will be telling you. Been planning my setup for a month now and Im still learning different things about it.

 

You will be able to safely use much larger amounts of nitrous if you use progressive controler of some kind.

Also, I would recommend you to take a look at http://www.forum.nitrous-advice.com
This is a very informative forum of Trevor Langfield...leading authority on nitrous design

 

Please forgive the bump......but that link above was good reading. I think this is good reading too.

It was just coincidence that the two articles I read last, had completely opposite points of view. I was pretty convinced by both to some degree.
Man it would be be a fun day if these two experts both turned up at once to help with your N2O install.


edited to correct NO2 to N2O.....I suspect that NO2 is constipation.
