I've finally got round to taking a couple of pics of my AEM water injection kit. Its a nice alternative to the aquamist stuff, and cheaper as well (thanks Dusty ). It can run up to 50% methanol mix with water (I'm currently running 25%). I'm very happy with the kit, there is a definate reduction in EGT on boost.
This is what you get in the box:
The 1 gallon tank includes a low fluid sensor. I mounted mine to the back of my sub enclosure in the boot. You can just see the filler cap in this pic.
I ran the water line down the n/s under the carpet and through a grommet into the inner wing, and then to the pump in the engine bay. The pump is mounted in place of the charcoal cannister. I made a mounting bracket out of 3mm aluminium that bolts to the charcoal cannister mounting points.
You can just see the pressure sensitive variable controller mounted on the back of the pump bracket (its normally covered with an aluminium cover plate). I've set it up to start the pump running at 0.5 bar and to reach full flow at 1.1 bar. I've also added a small additional fuse box at the bottom right of the pic. Its got the fuse for the water injection, as well as ones for my HIDs, remote start and smart windows - i got fed up of having loads of inline fuses cable-tied round the engine bay.
I welded a piece of aluminium to the Greddy hard pipe and drilled and tapped it for the injector nozzle. The kit includes 3 different nozzle sizes: the small one is too small for a supra, i'm using the medium one, and the large would be suitable for single turbos. The water hose is clipped into brackets mounted on the inner wing.
I modified the right hand warning cluster for the status LED. On is pump running, and it flashes for fault codes.
I added a master switch mounted in the upper glove box; this does not come with the kit.
Finally the completed engine bay:D
