Engine Management Systems

We can install Haltech, Microtech, Wolf EMS, APEXi S-AFC's, and other types of Engine Management Systems. Water Injection is also a popular for stand alone computers as a lot of our customers use it for high horsepower applications.

-Basic Engine Management System- install price: $800
Includes terminated harness wrapped, all connections are soldered / crimped and dr-25 heat-shrink tubing is used.

From fuel control units like the APEXi Super-AFC's to full blown engine management, we can do it all. Please contact us for help determining which is the right system for you.

-Water Injection- install price: $200-$400

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.
