DeatschWerks 850cc Fuel Injectors for Turbo & E85 Builds
High-Flow Fueling for Performance Applications
As horsepower increases, injector duty cycle quickly becomes a limiting factor. The 850cc/min flow rate offers substantial fueling headroom for modified engines requiring higher fuel volume under boost or high RPM conditions.
These injectors are ideal for supporting:
- Turbocharged applications
- Supercharged builds
- Flex fuel and E85 tuning
- Upgraded fuel systems
- Standalone ECU setups
- High-horsepower street builds
The larger injector capacity helps maintain safe air/fuel ratios while supporting consistent combustion under heavy load.
Set of 4 850 cubic centimeter side feed injectors for Subaru STI EJ25 04-06, Legacy GT EJ25 04-06, Impreza 2.5RS 97-98. Founded in 2004, DeatschWerks, LLC is an organization dedicated to providing application specific, high-performance fuel systems solutions.
Matched Set for Accurate Fuel Delivery
Each injector in the set is carefully flow-matched by DeatschWerks to ensure balanced fuel delivery across all cylinders.
Benefits of matched injectors include:
- Improved idle quality
- More precise tuning consistency
- Stable air/fuel ratios
- Better throttle response
- Reduced cylinder-to-cylinder variation
Consistent injector performance becomes especially important in boosted engines where even minor fueling inconsistencies can affect power output and engine reliability.
Situated in Oklahoma City, Oklahoma, DW operates out of its own 12, 000 square feet facility that houses all the company’s functions including design/engineering, manufacturing, quality assurance, and administration.
Ethanol-Compatible Construction
Modern performance builds increasingly rely on ethanol-based fuels like E85 due to their cooling properties and increased knock resistance. The DeatschWerks 850cc injectors are engineered to support ethanol-compatible applications while maintaining durability under demanding operating conditions.
These injectors are designed to withstand:
- Ethanol-blended fuels
- High fuel pressure
- Elevated engine bay temperatures
- Aggressive tuning environments
- Long-term street and track use
Because nothing says “weekend ruined” quite like discovering your fuel system hates ethanol after you already filled the tank.
DeatschWerks roots were established by offering high Drift drop-in fitment fuel injectors for Nissan engines such as the preferred SR20DET, VG30DETT, and VQ35DE.
Excellent Choice for Street and Track Builds
The 850cc size is commonly used for builds targeting moderate to high horsepower levels while still maintaining respectable drivability when properly tuned.
Popular applications include:
- Turbo imports
- Subaru WRX and STI builds
- Honda turbo setups
- Mitsubishi EVO platforms
- Nissan turbo projects
- Domestic boosted applications
With proper tuning, these injectors can provide excellent street behavior while supporting substantial power increases.
Soon thereafter, DW expanded to cover Subaru, Mitsubishi, and other popular sport compact makes.
