Start with your exact engine, chassis, fuel and tuning plan. A fuel pump, a port injection kit and an injector controller are different parts of a fueling setup; buying one does not automatically provide the others.
Which page should I shop?
- S58 port injection kits — compare supplemental injection hardware and injector options.
- S58 fuel pumps — review pumps for your specific chassis and configuration.
- N54 fuel pumps — match the pump and installation requirements to your BMW.
- S55 fuel pumps — compare the listed applications and options.
- All Precision Raceworks products — find related rails, harnesses, lines and accessories.
What comes with an S58 port injection kit?
The Precision Raceworks S58 kit offers 750cc, 950cc and no-injector options. It works with the stock manifold and uses a separate injector controller. Check the selected option carefully: a no-injector kit does not include injectors, and the controller must be selected separately unless your particular listing explicitly includes it.
Do I need a controller and tuning?
Plan the controller, wiring and calibration with your tuner before ordering. Precision Raceworks lists ReFlex Lite and ReFlex Plus controller options for its S58 kit. Controller features and vehicle integration differ. Confirm the harness and sensor connections for the exact combination you intend to run.
How should I choose injector size?
Have your tuner select the injector specification for your fuel, power target and calibration. The advertised cc rating alone is not a complete buying decision; compare the supplier's flow data and operating conditions.
Pre-order checklist
- Record your model year, chassis, engine and existing modifications.
- Confirm the product's part number and complete vehicle fitment.
- List the exact option selected and what is included in the package.
- Check whether you also need injectors, a controller, harnesses, sensors, fuel lines or fittings.
- Ask your installer and tuner to review the complete parts list.
- Check availability and the shipping policy before booking installation.
