Shown above are the new CNC'd injector bosses available for use with standard 14mm O-ring type Bosch injectors. These are available in either a steel or aluminum base depending on what type of material you will be welding to. Two piece design gives total retention. The tops are threaded for 1/8 NPT fitting so you may use straight or 90 degree AN or brass fittings for attachment to your fuel rail or supply block. Comes with stainless steel socket head cap screw hardware. Bosses are machined at 45 degrees on weld face. You can use your own injectors or buy 300, 420 or 570cc ones from us.

Are you looking for an alternative to those complicated, outrageously priced supplemental injector controllers? If so, our digital Extra Injector Controller may fit the bill.
The SDS EIC is a low cost, no frills, device capable of controlling 2 or 4 supplementary fuel injectors on high boost applications for those wishing to keep their stock fuel injection. You retain the off boost driveability and emissions of the OE system and have full control over the extra fuel you need under boost with a turbo fitted or at higher than stock boost pressures. Max boost pressure is 21psi. May not be suitable on engines equipped with distributorless or coil on plug ignition systems due to the lack of a suitable tach signal.
Our EIC control box measures only 4.4 X 2.4 X 1.25 inches allowing easy under dash mounting.
The SDS EIC gives you automatic rpm and boost compensation to 22 psi with its sophisticated microprocessor. Duty cycle LEDs keep you informed of injector duty cycle in 25% increments. Hookup is easy with just 3 wires and a vacuum hose plus the injector wires.
Simple controls allow quick, easy adjustments. The boost threshold knob permits you to set the boost pressure that you wish the unit to start injecting at. The fuel gain control allows you to fine tune fuel delivery to your specific needs from 1 - 100%. The internal microprocessor and MAP sensor control fuel flow from your knob selections proportionally with RPM and boost pressure. This permits a trickle just coming on boost at low rpm, to a storm at full boost and high rpm.
The 2 injector system is designed to have the injectors mounted in front of the throttle body or in the intercooler discharge tank / pipe.
The 4 injector model is designed for high boost, 4 cylinder engines mounting 1 injector in each manifold runner for excellent fuel distribution.
Injector bosses must be TIG welded in position.
