Nitrous on 2003 Mazda Protege
We are putting spray on my friends stock, 2003 mazda protege. Is it possible to run a 75 shot on this car? We would like to run a 100 shot, but we realize that this is too big. Any opinions would be appreciated.

70hp is too much, 60 is as high as I would go on stock internals.
I swear by ZEX for daily drvien street cars as it is not the most powerful kit but it is the safest. It has 3 seperate back-ups to prevent the juice from spraying when the engine can't handle it. It also shoots the nitrous based solely on how much fuel pressure you have up to your maximum jetted size. Very cool feature.
Prepare to buy a new clutch after about 4 good sprays.

ZEX makes both a wet and dry kit. I prefer the dry kit. Everyone I know who has blown a motor with N20 has a wet kit. EVERYONE. Also, the people who have blown a motor with a dry kit haven't used a ZEX kit.
The ZEX DRY kit uses the stock FPR on the fuel rail for it's readings. Basically what you'll do is disconnect the vaccuum line running to the FPR and plug into the ZEX NMU (nitrous management unit) Take anothervaccuum line and plug it back into FPR. The NMU will basically sit in-line. It senses the fuel pressure, knows how much N20 to inject and slowly starts increaseing fuel pressure....while it's doing this if it feels the FPR drop pressure the N20 stops spraying alltogether uintil it builds up proper pressure again...no effort is needed on your part. Its all controlled in the NMU.
