1.0 INTRODUCTION & SYSTEM REQUIREMENTS
Holley Performance Products has written this manual for the installation of the STEALTH TERMINATOR™ EFI TBI fuel injection system.
This manual contains the information necessary for the installation of this kit. It also contains all tuning information. Please read all the
WARNINGS and NOTES, as they contain valuable information that can save you time and money. It is our intent to provide the best
possible products for our customer; products that perform properly and satisfy your expectations.
1.1 Engine Requirements
Before moving forward with the installation, please verify your vehicle meets the engine and fuel system requirements below:
 Engine is a naturally aspirated (no supercharger, turbocharger, etc.) V8
 Engine horsepower is between 250 – 600
 Engine has a 4 BBL, 4150 style square flange or universal flanged spread bore intake manifold*
 Unleaded fuel only
 Any RTV silicone sealants used on the engine are sensor safe
* Any square flange Holley type intake manifold will work. A spread bore intake manifold may work with no adapter as long as it is an aftermarket
“universal flange” (meaning it has dual bolt patterns), and as long as it has enough material such that no vacuum leaks occur along the perimeter of the
throttle body. If there is not enough material, a sealing plate (Weiand® PN 9006) can be used. Factory dual plane intakes will require an adapter (PN
17-6).
NOTE: The STEALTH TERMINATOR™ system requires the use of the supplied 5/16” thick gasket to provide proper clearance.
1.2 Fuel System Requirements
A complete high pressure EFI fuel system must be installed for the STEALTH TERMINATOR™. The pump should be capable of
supplying 255 liters/hour or 400 lb./hr. of fuel at 45 PSI. If using an in-line fuel pump, there should be a coarse pre-filter before the pump.
All systems should contain a 10 micron post filter after the fuel pump. An EFI fuel pressure regulator is required. See Figure 1 below for
an example when utilizing a bypass regulator.
Holley offers four fuel system kits. These kits contain all components except the return line. They include detailed instructions
