FAQ
How much power are 24 LPM nozzles good for?Capacity depends on turbo, pump, tuning, and use-case. 24 LPM nozzles are a solid step beyond stock for towing-plus or street performance with the right supporting mods.
Do these install on my existing LBZ injectors?Yes—these are nozzles only. They must be professionally installed on your Bosch LBZ injectors with proper cleaning, torque procedure, and sealing hardware.
What supporting mods are recommended?A quality lift pump, healthy CP3 (or stroker/twin CP3 for bigger goals), free-flowing intake/exhaust, and calibration that matches your airflow and usage.
Will I need custom tuning?Yes. Any change in injector flow should be paired with appropriate calibration to maintain drivability, fuel economy, and safe EGTs.
