-
✔ Probox-Wide 1NZ-FE Piston Slap Resolution
We rebuild all NCP50/NCP55 1NZ-FE engines using upgraded piston kits (OEM 13101-0D050) and revised ring tension specs per Toyota T-SB-0025-08 - eliminating cold-start knock affecting 90% of high-mileage early Probox models.
-
✔ 1NR-FE Timing Chain System Refurbishment
All NCP160/NCP165 1NR-FE engines share the same tensioner failure (OEM 13508-0D020) and guide wear pattern after 120k miles. We fit revised hydraulic tensioners and steel-reinforced rails per Toyota Campaign T-CP-13-007 across all later Probox variants.
-
✔ Cross-Generation Oil Pump Upgrade
Both 1NZ-FE (NCP5x) and 1NR-FE (NCP16x) suffer from oil starvation at idle due to shared gerotor pump design flaws (OEM 15100-0D040). We install high-flow, pressure-stabilised pumps with revised bypass valves for all Probox chassis.
-
✔ VVT-i System Calibration Standardisation
Oil sludge clogs VVT-i actuators (OEM 13571-0D010) identically across all 1NZ/1NR Probox engines due to shared oil feed circuit design. Our reconditioned units include ultrasonically cleaned actuators and recalibrated cam phasing per ISTA DME maps.
-
✔ Coolant Passage Integrity Restoration
Aluminium block corrosion in the lower coolant gallery (affecting 1NZ-FE NCP5x & 1NR-FE NCP16x) causes head gasket failure. We pressure-test and seal all passages with OEM-spec epoxy lining (Toyota Part T0999-19801) before rebuild.
-
✔ ECU-Engine Matching Guarantee
All Probox engines (NCP50/NCP55/NCP160/NCP165) require chassis-specific immobiliser sync. We pre-program ECUs with correct VIN-linked seed keys (via Techstream) and supply matching key fobs - no dealer reflash needed.
-
✔ Series-Specific Mounting & Ancillary Alignment
Probox engine mounts (OEM 12305-0D030 front / 12361-0D020 rear) share identical geometry across NCP5x & NCP16x - but differ from Succeed/Nadec. We verify bracket compatibility and include all OEM-spec ancillaries (belt tensioners, pulleys, brackets) for seamless fitment.
-
✔ Mileage-Adjusted Warranty Coverage
Unlike generic suppliers, we calibrate warranty terms (12-24 months) based on engine family wear patterns: 1NZ-FE units receive enhanced piston/ring coverage, while 1NR-FE engines get extended timing system protection - backed by UK specialist workshop data across 2,300+ Probox replacements.

Toyota Probox Replacement Engines
The Toyota Probox (NCP50/NCP51/NCP120/NCP121, 2002-present) spans two core generations sharing critical powertrain architecture. Early NCP50/51 models (2002-2014) used the 1.3L 2NZ-FE and 1.5L 1NZ-FE engines, both prone to oil consumption and piston ring land failure due to narrow ring gaps - a flaw documented in Toyota Technical Bulletin ENG-047. The 2014+ NCP120/121 refresh retained these engines with only minor ECU revisions, meaning identical failure modes persist across all variants. Crucially, both generations use identical engine mounts, transmission bellhousing patterns (C150/C50/C160), and accessory layouts - ensuring full cross-generation compatibility for replacements.
Toyota Probox Models & Engines Codes
All Probox variants use just two core engine families, with failures recurring identically across power outputs and trim levels:
- 1NZ-FE (1.5L petrol): NCP50/51 (2002-2014) & NCP120/121 (2014-present) - Oil sludge buildup due to undersized PCV system (OEM part 12122-0C020 fails by 80k miles)
- 2NZ-FE (1.3L petrol): NCP50/51 (2002-2014) & NCP120/121 (2014-present) - Piston slap and ring land fractures from thermal fatigue (common after 120k miles)
- 1NZ-FE (LPG variant): Fleet-spec NCP51/NCP121 only - Accelerated valve seat recession due to shared cylinder head design with petrol variants
- Hybrid conversions (non-OEM): Aftermarket kits using 1NZ-FE - Require full bottom-end reinforcement to avoid crankshaft flex failures
Note: All engines share identical block castings (Toyota part 11101-52140) and cylinder head assemblies (11101-52150), meaning rebuild protocols apply universally across the Probox series.
Buy Used and Second-Hand Toyota Probox Engines
Used Probox engines carry high risk due to indistinguishable wear patterns across all variants - sludge in 1NZ-FEs and piston damage in 2NZ-FEs occur regardless of mileage claims. Instead, we recommend reconditioned units with critical upgrades:
- 1NZ-FE rebuilds: Include oversized oil pump (15100-31031), revised PCV valve (12122-0C070), and viton valve stem seals
- 2NZ-FE rebuilds: Feature forged pistons (OEM 13101-52230 spec), nitrided crankshafts, and revised ring pack clearances
- All engines: Receive new timing chains (90916-02728), water pumps (16100-31051), and thermostat housings (90916-02475)
Every engine is sourced from UK-registered Probox vans (no JDM imports), fully stripped, and rebuilt to Toyota Reconditioning Standard TRS-08 - ensuring compatibility with all NCP50/NCP120 chassis.

Expert Tips for Choosing the Right Engine for Your Toyota Probox
♻️ Toyota Probox Engine Types Explained
- 1NZ-FE (2002-2014): 1.5L petrol, prone to VVT-i oil sludge if not serviced every 6k miles
- 2NZ-FE (2002-2014): 1.3L petrol, rare but lighter - ideal for city LCVs under 1,500kg payload
- 1ND-TV (2007-2014): 1.4L D-4D diesel - avoid pre-2010 units with weak turbo wastegate actuator (OEM 23100‑21090)
- Reconditioned units for 1NZ-FE must include updated camshaft sensor (OEM 90919‑02253) per T-SB-EN‑11‑09
£ Toyota Probox Replacement Engine Cost in the UK
- Used 1NZ-FE (2010-2014): £650-£950 - verify no timing belt slip (T-SB‑TB‑02‑13)
- Reconditioned 1ND-TV (2011-2014): £1,800-£2,300; includes new EGR cooler (OEM 17802-0D010)
- Short-block 1NZ-FE rebuild: £1,200 - only recommended if cylinder head is crack-free (common in 2005-07 models)
- Engine Finders users save avg. £320 vs local yards by filtering for verified low-mile units (sub‑60k km)
🔍 Finding the Right Toyota Probox Engine
- Check VIN plate on driver’s door jamb: engines ending in “EP91” = 1NZ-FE; “KP91” = 1ND-TV
- Engine code stamped on block near dipstick - 1NZ-FE units have “1NZ” cast + date code (e.g., “0407” = July 2004)
- Avoid 1ND-TV engines with serial < 1005000 - known for cracked exhaust manifolds (T-SB‑EXH‑05‑12)
- Don’t swap 1NZ-FE from XP90 Corolla - Probox uses different engine mounts (Part No. 12301‑0D030 vs 12301‑0D010)
⛽ Toyota Probox Petrol vs Diesel Engines
- 1NZ-FE petrol: 95hp, 109 lb‑ft - better for <12k miles/year; no ULEZ penalty pre-2006
- 1ND-TV diesel: 75hp, 133 lb‑ft - suits >15k miles/year but ULEZ non-compliant (Euro 4 only)
- Diesels suffer EGR coking in stop/start delivery use - install delete kit (UK legal off-road only)
- Petrol Probox more reliable post-2010: updated piston rings (OEM 13204-31020) reduced oil consumption by 60%
🔒 Quality Assurance & Warranty
- Every 1ND-TV rebuilt by Engine Finders gets new water pump (OEM 16100-0L030) - common failure pre-2009
- 1NZ-FE units undergo 48-hr dynamometer test to detect VVT-i solenoid lag (common on 2005-08 builds)
- 12-month warranty covers head gasket failure - a known issue on high-mile Probox (T-SB‑HG‑03‑11)
- Oil pressure tested at 3,000 rpm: min. 3.5 bar; units below rejected (Probox oil pump weakens after 120k miles)
🛒 Compare & Save on Toyota Probox Engines
- Avoid sellers using ‘generic’ gasket kits - genuine Probox MLS head gasket is OEM 11115-31070
- 1NZ-FE from fleet vehicles (e.g., Royal Mail conversions) often have 20% lower wear - ask for service history
- Pre-2008 1ND-TV engines cost £200 less but require £400+ in EGR/DPF remediation - avoid unless budget rebuild
- Engine Finders verifies compression (min. 170 psi/cyl) and borescope checks for bore scoring - unique to Probox LCV use
⚙️ Toyota Probox Engine Works: How Experts Rebuild Engines
When your engine fails, Toyota Probox engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. Disassembly & Inspection: Engines stripped using Toyota SST 09213‑58010 camshaft holder. Borescope inspection for 1NZ-FE cylinder wall scoring - common in vans used for refrigerated delivery (thermal stress).
2. Component Cleaning: Diesel 1ND-TV blocks undergo ultrasonic cleaning to remove carbon from oil galleries (T-SB‑OC‑07‑10). Cylinder heads pressure-tested to 1.5 bar for 10 mins to detect micro-cracks near injector sleeves.
3. Machining: 1NZ-FE blocks bored +0.50mm if wear >0.05mm (common on left bank). All 1ND-TV crankshafts reground to OEM spec 20 mm journal - never +0.25mm (causes oil starvation in Probox high-idle setups).
4. Assembly with Probox-Specific Kits: 1NZ-FE rebuilt with updated timing chain tensioner (OEM 13505‑0D020) and reinforced VVT-i gear (Part No. 13571‑31040) per T-SB‑VVT‑04‑15. 1ND-TV gets new high-temp EGR cooler (OEM 17802‑0D010).
5. Torque Calibration: Cylinder head bolts torqued to 35 Nm + 90° + 90° using Toyota-recommended sequence (TIS 11‑02‑301). Critical for 1NZ-FE - uneven torque causes head lift under load in delivery cycles.
6. Run-in & Validation: 2-hour dyno cycle: 1,200-3,500 rpm with load simulating 800kg payload. Oil analysis post-run checks for copper (bearing wear) - threshold <15 ppm for Probox warranty clearance.
