WP Stage 2+ — 470–500bhp / 515–530ft/lb
Stage 2+ pushes the stock B58 turbo to its absolute ceiling. With a performance downpipe, uprated high-pressure fuel pump and panel filter, we extract 470–500bhp and 515–530ft/lb — the maximum the factory turbocharger can safely deliver.
The HPFP upgrade is the key unlock at this stage. Beyond Stage 2 power levels, the factory fuel pump can't deliver enough fuel to keep the engine safe under full load. A higher-flowing pump (typically the B58TU/Supra unit) solves this completely, allowing us to run the boost and timing the turbo is truly capable of.
What's included: Custom dyno calibration with before & after printout Hardware required: 4" performance downpipe · Uprated HPFP · High-flow panel filter Recommended: Upgraded chargepipe · ZF gearbox calibration (add-on) · NGK 94201 spark plugs

99 RON fuel required for optimal results. ⚠️ Decat downpipes may affect emissions compliance and MOT testing. Sports cat options available for road use.
