INASNT,
know my way around nitrous. The 100HP of nitrous is fine, just as fine as a 100HP increase with a hiflow turbo. As long as the engine internals can handle the extra power --- regardless of what provides it. The nitrous has the added benifit of correct mixture out of the box Vs new turbo that requires re-map and larger injectors etc.
As I said earlier the 50 shot is for starters, to get things sorted nicely.
The purge kit would be a good idea if I was racing and had a 250HP or so direct port. Keeps the lines 'liquified'. little power shots like mine don't need it.
Bottle warmers are good in cold weather, for the most part Perth is hot enough (except some parts of winter) to go without one.
Driving on the street with it?
No, I can't do that! Thats illegal in W.A.
