Bad idea and a total waste of money!
Don't waste the time or the money. Put the money towards a nice high end engine such as a Novarossi 528XRS if you want insane power.

Like everyone has already stated, NO. If you don't get it by now then you might never.
That's not true, being 2 stroke isn't a problem. They can supercharged, turbocharged and nitrous injected like any other motor. But like everyone is saying here, they don't work on these small engines.
please explain in excrutiating detail how this works?
I've always been under the impression that you had to be able to close the exhaust port to keep any reasonable abount of fuel/O2 in the combustion chamber for the super and turbo to really work......NOS is just a joke on smaller engines like this....unless you had a dyno to show the power bands you'd probably never even notice a difference in performance...
I haven't personally done a forced induction on a 2 stroke, but I spent 10 years doing supercharger and turbocharger rebuilding. I rebuilt them for all kinds of motors, yes, some were 2 strokes. They were mostly motorcycle racers, but a couple were for outboard boat engines.
Here's some info from what I've heard and read about it.
Basically, the key is port timing and volumetric efficiency. You just have to watch out for too much overlap in the port openings, similar to using a cam that is too long on a 4-stroke. And you need to achieve a higher than 100% volumetric efficiency. If your engine is highly "ported" for peak power there is more of a problem. Two strokes respond very well to porting combined with the proper sized expansion chamber and the result is a poor-man's supercharger, without one. A mild engine will have a better chance of having mild port timing in it and a narrower rpm band. Volumetric efficiencies much greater than 100% can be achieved in narrow rpm bands
Turbocharging a 2 stroke doesn't destroy all exhaust resonances, you have to place the turbo after the expansion chamber. And match the turbine and housing carefully against the resonances in the pipe.
The supercharger is a bit simpler than a turbo since all you need to do is modify the intake system, rather than a complete setup with exhaust, waste gate, etc. And you still need to make a system to drive off the crank or clutch basket. The biggest thing here is, you have to have control over the pressure difference in the engine though. If the exhaust backpressure would get close to the boost,it would run on exhausts and quickly melt the piston.
N2O simply adds it's own fuel and oxygen to make extra HP. Doesn't matter if the motor is 2 stroke or 4, it works the same.
That's probably not what you call excrutiating detail, but it's all I've got. I haven't worked in that field for over 10+ years.

:constipat i was wondering how do you fill the shocks on theas dam trucks
i try and i cand push it all the way down eavn when i take some oil out
pleassssssssssssssssss help:stupid:

Remove the springs, then loosen the cap about a turn and a half, then wrap a rag around it, and compress the shock. While holding the shock compressed, tighten the cap. Then add your springs.

Why would you even consider something questionable like this when for less than $300 you can get a brand new big block with more power than you will ever need.
The most important things are tuning and gearing. Even my very old Picco .26 still runs super strong when its tuned properly. I have an unused Picco .28 still sitting in its original box because my old .26 refuses to dies and it makes great power. Maybe I'll kill the old .26 this year
