Water / Alcohol / Methanol Injection Parts List
Here are all of the parts that you'll need to build this system. As you'll see this kit is modular and allows for different pump, nozzle and tank options depending on your needs. Also, I've done my best to make the items
on this list affordable and easy to find.
This system is very similar to the higher price offerings out there, and will give you the same if not better results at a fraction of
the price! Plus, it really is a fun and easy do it yourself project that will reward you with many years of extra horsepower. I get loads emails from folks telling me how simple the kit was to install and how incredible the performance gains are, so I'm sure you'll have the
same experience. Tell me about your experience by

| Water/Alcohol/Methanol Pump Options
Both of these pumps are excellent. For most applications, I recommend the first option.
For high boost/big engine cars or methanol, go with the bigger pump.

| Spray Nozzle Options
I recommend starting small and working your way up. I have had good luck with
the small and medium sizes in small displacement engines in the 150-450hp range. The large nozzle would be good for a large
displacement engine making more than 400hp. If you're unsure, start small and work your way up.

| Water/Alcohol Tank. |
I've used the stock washer fluid reservoir in many cars since it's a decent size and already mounted in the engine bay.
Another inexpensive option is the coolant overflow jugs found at most parts stores. Lastly, you can go to your local
"U-pull-it" salvage yard and find a nice jug out of an 80's import that will work perfectly. Price? $5.00-$15.00
Either way, insert a 3/8" fitting into the tank for free flow to the pump. Don't forget to use silicone on the threads of the
fitting.
