H703-1255; six Raptor Stage 1 direct injectors.
A first fuel-system upgrade with a pump you can build on.
Nostrum Stage 1 puts the first pump and injector upgrade together: Big Bore, six Stage 1 injectors and the fitting hardware for your Raptor. The emphasis is on extra pump supply with a modest injector increase, giving you a useful starting point when both parts of the high-pressure system need changing.
The pump has 47% more flow than stock; the injectors provide an 11% increase over the original 3.0L set. You are buying the pump, six injectors and application-specific fitting hardware together, with calibration and installation arranged separately.
SKU: H186-2053
The first step in the Big Bore range
Big Bore supplies 47% more pump flow than stock; the Stage 1 injectors supply 11% more than the original 3.0L set. That puts the emphasis on a substantial pump upgrade with a smaller injector step.
It is a combination to compare when developing an original-turbo Raptor around an agreed fuel and calibration plan. If the intended fuel demand calls for more injector capacity, Stage 2 offers 24% above stock and Stage 3 offers 96%, both with the same Big Bore pump. Choose for the engine you intend to finish, including any upgrades already planned.

Keep useful hardware as the build develops
If you move to larger injectors later, a suitable and serviceable Big Bore can stay. Buy the new injector set separately and have the calibration revised for its characteristics. That avoids buying another complete bundle just to change injector size.
The same principle applies now: if only the pump needs changing, the separate H086-1953 pump kit is available. The full Stage 1 bundle suits a purchase where both the pump and injector specification are changing together.
Choose the fuel you will use
The hardware supports petrol and ethanol with the right calibration. Think about everyday availability as well as the fuel you would like to use for performance driving. The finished truck still needs to start on a cold morning, idle in traffic and run cleanly at light throttle; those conditions belong in the tuning work.
ESSIM ethanol measurement is available separately. Automatic flex-fuel operation also requires an ECU strategy that uses the measurement. If your normal grade or blend may be unavailable on a trip, agree the alternative before leaving.
Fitting and ownership
Professional installation and ECU calibration are required and priced separately. Establish software support for your ECU, then plan the pump, fuel-line and injector fitting alongside calibration. Any tank-side fuel-supply upgrade is separate and depends on the engine’s demand.
We can provide delivery information before you book fitting. Nostrum’s limited lifetime hardware warranty applies subject to its terms.

Frequently asked questions
Is this required for a Stage 1 remap?
No. The name identifies Nostrum’s hardware combination. Your tuner’s assessment of fuel demand establishes which pump and injectors the engine needs.
Can I move to Stage 2 without replacing Big Bore?
Yes, where the pump remains suitable and serviceable. Stage 2 uses the same pump with larger injectors. The injector change requires revised calibration.
Can I use normal UK petrol?
Yes, with calibration for the petrol grade you will use. Ethanol compatibility also gives you options with the appropriate supporting fuel system and tune.
Is an ethanol analyser included?
No. ESSIM is separate and needed only where your fuel strategy requires measurement. An analyser alone does not create automatic flex-fuel operation.
How much power does Stage 1 add?
It adds fuel capacity. Engine airflow, fuel and calibration determine how much output that supports. The pump and injector flow increases do not translate directly into power gains.
Can I buy the pump on its own?
Yes. Choose Big Bore H086-1953 when your existing injectors already meet the build’s requirements. Both routes need fitting and calibration.
Will it fit the diesel Ranger Raptor?
No. This bundle is for the 2022+ Ranger Raptor 3.0 V6 EcoBoost petrol.
