650cc / 950cc Starion and Conquest Upgrade Fuel Injectors (Primary & Secondary Set)
Proudly Accepting
Upgrade your Mitsubishi Starion or Chrysler Conquest (1987-1989) with SouthBay’s 650cc/950cc fuel injector set. This direct-fit performance upgrade replaces the aging factory primary and secondary injectors. Specifically engineered to handle increased boost on the 2.6L G54B Turbo engine, providing the precise fueling needed for modern tuning while maintaining factory-like idle and driveability.
High-Performance TBI Upgrade for Starion & Conquest
SouthBay’s 650cc (Primary) and 950cc (Secondary) injector set is the go-to solution for enthusiasts looking to revitalize or performance-tune their Starion or Conquest. The factory TBI (Throttle Body Injection) system is notoriously sensitive to injector health; our modern replacements offer superior atomization and faster response times compared to the decades-old OEM units.
Key Product Features:
-
Direct Fitment: These injectors are designed to drop directly into the factory throttle body. No modifications to the housing or fuel lines are required.
-
Balanced Performance: The 650cc Primary and 950cc Secondary staggered sizing ensures smooth transition and proper fueling across the entire RPM range, especially when entering boost.
-
Modern Internals: Built with updated technology to resist "heat soak" and fuel gumming, common issues with original StarQuest injectors.
-
Flow Matched: Every set is rigorously tested and matched to ensure consistent delivery, which is vital for engine safety on the 2.6L G54B Turbo engine.
-
Fuel Compatibility: Fully compatible with all standard street gasolines and common performance additives.
