The advantage of water injection is it cools intake temperatures on average by 65 degrees Fahrenheit. It also contributes to allow more timing advance with the same octane fuel without detonation. Detonation being the number one reason why we recommend water injection. Water also absorbs heat better and all of this can result in running leaner air fuel ratios.

All EMS installs can be done for RX-7 1st Gen, RX-7 2nd Gen, RX-7 3rd Gen, R100, RX-2, RX-3, RX-4, and other rotary powered vehicles such as our rotary powered turbocharged 914 Porsche. Piston applications are available as well.
