This is Nostrum's Standard Bore Plus pump kit for the 1.6 EcoBoost Fiesta ST: a laser-welded assembly with 1.03 cc\/rev of geometric displacement, moving 36 percent more fuel than standard. It lets a tuner hold rail pressure through the midrange, bring boost in earlier for stronger low-end torque, and run full pump E85 instead of mixing at the forecourt and hoping the ethanol content holds. Nostrum builds it as a direct bolt-on kit that reuses the standard low-pressure feed line.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMk7 Fiesta STs that are fuelling-limited before they are turbo-limited.\u003c\/li\u003e\n\u003cli\u003eAnyone done with blending E85 by hand at the forecourt.\u003c\/li\u003e\n\u003cli\u003eStock-turbo cars chasing low and mid-range torque, not a headline peak.\u003c\/li\u003e\n\u003cli\u003eA first fuel step on a car that will later take upgraded injectors.\u003c\/li\u003e\n\u003cli\u003eTrack and sprint Fiestas needing steady rail pressure on hot laps.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere The Stock 1.6 Pump Runs Out\u003c\/h2\u003e\u003cp\u003eA direct-injection pump is camshaft driven, so its output is tied to engine speed as well as size. On the 1.6 EcoBoost the factory unit is the first thing to give up once boost or ethanol content climbs, and rail pressure falls away exactly where you want torque. The pump fixes supply, an injector fixes delivery, which is why this one usually goes on first.\u003c\/p\u003e\u003ch2\u003eGetting To The Full 240 Bar\u003c\/h2\u003e\u003cp\u003eThe pump is commanded to 180 bar as standard and capable of 240, but the factory rail sensor stops reading at 20 MPa, so the higher figure needs a sensor swap; Nostrum names the genuine Bosch 0261545040 for that route. It rates the step from 200 to 240 bar at roughly 10 percent more injector flow, worth planning if a set of \u003ca href=\"\/products\/nostrum-fiesta-st-1-6-ecoboost-high-flow-injectors\"\u003ehigh flow 1.6 injectors\u003c\/a\u003e is coming next.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: Direct-injection high pressure fuel pump kit\u003c\/li\u003e\n\u003cli\u003eSKU: H086-1213\u003c\/li\u003e\n\u003cli\u003eVehicle Application: Ford Fiesta ST 1.6 EcoBoost, 2014-2019\u003c\/li\u003e\n\u003cli\u003eGeometric displacement: 1.03 cc\/rev, 36 percent more flow than the factory pump\u003c\/li\u003e\n\u003cli\u003eIncluded Items: pump, mounting flange, alignment tool, mounting bolts, low-pressure line adapter, line-bending fixture, install guide\u003c\/li\u003e\n\u003cli\u003eRequired separately: supporting calibration; rail pressure sensor if you want the 240 bar figure\u003c\/li\u003e\n\u003cli\u003eFitment type: vehicle-specific\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eThis kit covers the 1.6 EcoBoost Fiesta ST built between 2014 and 2019.

The standard low-pressure feed line is reused and reshaped with the supplied fixture, so allow workshop time for it. Fitting instructions are in the box.
