havn't seen it on a z31 but a turbo is a turbo when ti comes to water/alcohol injection, the problem as I see ti is keeping things refilled and wirking properly, if a selenoid dies or you run out of fluid under boost things go boom

and what you get out of it is a cooler denser charge with a higher octane rating, this allows you to run more boost, most comonly it's used in place of an intercooler, rarely you'll see someone runnign both on a full out drag car or someone taht just has too much time on their hands

There is no reason or benefit to running water injection on an n/a motor unless you're running 11:1 compression, save your time and money for something useful

theres no money to put in just buying the water an achol is it you can use your wiper filler just have it shoot into the intake. don't have to buy a kit.

the whole concept for water alcohol injection is to cool the intake charge adn effectively prevent pre-ignition, there si no use putting it on an stock motor, and if you were to build a high compression mtoor or high boost with no intercooler you'd want specific metered control of delivery, if an orifice is too large the engine vacume could suck the tank dry and hydrolock your engine! please don't waste your time and energy doing somethign that coud well damage your car! if you want to mod something save your pennies and buy a wrecked turbo car, I've bought 2 z31 turbo's for $200 and $400 respectively, it's the best bang for your buck and you can sell off unused parts to offset the cost

we had a kid on the local board with an S-13 that swore by this trick, and the only thing it got him was made fun of, and an occaisional fireball when bouncing off the revlimiter. proving that alchy injection with out turbo is 100% useless
