Holley Sniper EFI Quadrajet Self-Tuning Fuel Injection Systems

Holley Sniper EFI Quadrajet self-tuning fuel injection systems are ideal replacements when you're tired of rebuilding the 50-plus-year-old Rochester Quadrajet (Q-jet) on your classic ride. They're the first bolt-on, spread-bore, EFI throttle-body systems not requiring any additional adapters, sealing plates, or intake manifold swaps. They retain the same great features as the 4150 Sniper EFI version (four 100 lbs.-hr. injectors; built-in timing control; high resolution 3.5 in. full color touchscreen; etc.). Their throttle body will support naturally aspirated power up to 500 hp. In addition, they offer multiple fuel inlet configurations that allow for a stock-appearing installation and fit most stock air cleaners. Modernize your Q-jet-powered classic vehicle with a Holley Sniper EFI Quadrajet self-tuning fuel injection system. They are offered individually or in Master kits with external fuel pressure regulator preset to 58.5 psi, 20 ft. of 3/8 in. Vapor Guard fuel hose, fuel pump, filters, necessary hardware, and bulkhead fitting to return fuel into the tank. Features, items, and specs: * Designed to deliver the signature "Rochester Roar" at wide-open throttle! * Throttle body-mounted ECU–no extra boxes to mount * Only 4 wiring connections required (battery positive and negative, switched ignition, and rpm) * Transmission provisions on throttle lever for TH350/TH400 and 200R4/700R4 * Universal throttle and transmission kick-down bracket * Brake booster adapter (if required) * Simple calibration wizard (answer a few questions about your engine and it creates the base map, then starts tuning on its own—no laptop required) * Internal fuel pressure regulator preset to 58.5 psi * 20 ft. of 3/8 in. Vapor Guard fuel hose * Fuel pump and filters * Necessary hardware and bulkhead fitting to return fuel to the tank * Genuine Bosch LSU 4.9 wide-band oxygen sensor provides real-time fuel map learning * OEM-style throttle position sensor (TPS) and idle air control (IAC) for years of dependable service * Clamp-on oxygen sensor kit ensures leak-free oxygen sensor installation with stainless steel T-bolt clamps and weld-ready oxygen sensor flange * United States Coast Guard approved (certified to ISO 8846, SAE J1171 requirements) * Available in three finishes--Classic Gold, Shiny, and Black Ceramic

Nitrous Express Stage 6 Nitrous Systems

That means you can pick one of the lower increases for an engine that's close to stock, and then ramp things up later on when you add forged pistons. Systems include: * Nitrous distribution plate * Supply hose and fittings * Solenoids * Switches * Wiring * Jets * Mounting hardware * Race fuel required for increases above 150 hp
