Nitros Oxide... Yay or Nay?
Depending on composition and source, E85 has an octane rating of 100 - 105[4] compared to regular gasoline's typical rating of 85 - 93. This allows it to be used in higher compression engines which tend to produce more power per unit of displacement than their gasoline counterparts. Since the reciprocating mass of the engine increases in proportion to the displacement of the engine E85 has a higher potential efficiency for an engine of equal power.
One complication is that use of gasoline in an engine with a high enough compression ratio to use E85 efficiently would likely result in catastrophic failure due to engine detonation, as the octane rating of gasoline is not high enough to withstand the greater compression ratios in use in an engine specifically designed to run on E85. Use of E85 in an engine designed specifically for gasoline would result in a loss of the potential efficiency that it is possible to gain with this fuel. Using E85 in a gasoline engine has the drawback of achieving lower fuel economy as more fuel is needed per unit air (stoichiometric fuel ratio) to run the engine in comparison with gasoline. E85 also has a lower heating value (units of energy per unit mass) than gasoline leading to a reduction in power output in a gasoline engine.

You guys should have started a new thread on fuel types 
N2O in my opinion is a way to overcome a sturdy engine that needs some more hp or tq at medium rpms. N2O is usually used on strong engines like American muscle V8's and non turbo Japanese engines because these engines 1) can handle the extreme compression in the cylinder 2) have adequate exhaust and 3) have adequate intake capabilities. Also, N2O is for short races in a straight line (like drag racing). "Short" because of the extreme compression on the engine and "straight line" because of the unpredictable power (hence all the $$$ for the fuel management system).
N2O for an X is a bad idea for several reasons. The X is limited by the exhaust and then by the intake. The X engine with the turbo and other intracacies would not handle the extra compression very well. If you put N2O on an X, you would overload the exhaust, the intake wouldn't supply well and you would be putting a HUGE strain on a delicate engine. This is why people first mod the exhaust and then mod the intake.
If you own an X, you should drive it any way you want, in any type of race that you want. However, it will be most competitive in a rally or road course race. N2O in any car in a rally or road course race is a great way to blow your engine and/or send you spinning off the track. Any rally or road course race or even autocross won't let you race with N2O because they know you are going to hurt your car, hurt the track and probably hurt yourself if not another driver.
Great question though and an interesting discussion except for the off topic fuel debate.

N20 is just like anything else, its fine if you tune for it and use it properly
FI'd cars repsond VERY well to n20 and if you can afford it I'd say that a 50 shot (when tuned for it) is a VERY smart move.
you'll gain upwards of ~80HP

I run 1000cc injectors on my IX with the stock turbo and I average about 13-15mpg city driving with E85. I don't care though, the power increase over pump 93 octane is worth it to me (gained 60whp/90wtq over my pump gas tune).
i dont know about doing it in the X mr but i have a nx kit in my evo and it works great the power feels great and the car runs fine. i first put it on a 50 shot but felt weak so i went for the 75 shot and that one felt like the 150 shot i had on my ls1 camaro so all im saying is ive never had a problem with it and ive had it for over 1 year and as long as you do it right you ok
