Nitrous Questions
I'm not planning on going on the bottle, but I have been wondering a few things about the whole nitrous idea.
With an auto transmission, does it put any extra stress on the shifting process? I would think that it puts alot of stress on it, but I'm not sure. With a 5spd, do you hit the button and shift or do you leave it in gear and hit the button?

Any additional HP. will do better at breaking the tranny. Most of the N2O set ups work off a WOT (wide open throttle) switch, so it only applize the nitrous when the accerators all the way down.

With a 5-speed, the nitrous is disengaged between shifts. It can be controlled by a button on the shifter, or it can be set to activate at a particular throttle position.

this is why you shoudl get a zex kit
the zex kit will not spray between shifts i believe lots of the impreza guys run zex with the auto and have no problem be ware the 5mt and any power, the gears themselves are weak, they will break if you overpower them, the 4eat gears are at least twice as strong as the 5mt (excluding forester 5mt and MY04 5mt's)

I'm pretty sure that unless the driver flips a switch, even the ZEX kit flows nitrous during shifts on a 4EAT. I don't see how it could be otherwise because nitrous kits do not interface with the ecu or the tcu to know when a shift is occuring. The 5MT is definitely not a strong transmission, but I think it can handle a good nitrous shot if applied properly. There are lots of people pushing 300+ HP through bone stock 5MTs. The key is to avoid shock loading the transmission. This is when the gears start breaking.

People can get around 260 WHP before the 5spd starts to become a problem.

the forester at least, and i was under the impression that the 04 wrx's as well, use a different 5mt it is the 5mt that in the past was on the sti in japan before the 6mt came out, it's much heavier duty and has been proven so, apparently it's good to about 500hp, some in japan, who drive like grannys with it if that's possible have nearly 1000hp going through them
