N57D30 in Land Rover Defender.
Documented from 29 recorded sources: 7 of the ten mandatory blocks are carried by two independent publishers, 3 remain open. Internal confidence 74%.
(1Q) For the cited N57D30O1 740Ld specification only: longitudinal inline-six, four valves per cylinder, DDE 7.01, variable-geometry turbo, common-rail direct injection, 2,993 cc, 84 mm bore and 90 mm stroke, 16.5:1 compression, 255 hp at 4,000 rpm and 560 Nm at 1,500-3,000 rpm, paired with an 8HP70. A cited 435d variant instead uses DDE 7.31, multi-stage charging and 313 hp/630 Nm. No one power, DDE or turbo figure is valid for the full N57D30 family.
Status: SINGLE_SOURCE · Confidence 60%
Turbocharged common-rail diesel. N57D30 applications include a single variable-geometry turbo path and multi-stage/twin-turbo paths; the direct 2016 330d Defender build is described as single-turbo, while the cited 435d OEM data and Defender 130 vide
Prefer a complete, running and emissions-documented longitudinal BMW donor with its exact N57, matching ZF 8HP, torque converter, flexplate, engine and transmission harnesses, DDE, immobiliser/key/CAS components, selector, pedal, sensors, charge-air and emissions hardware. A documented route uses a 2016 BMW 330d single-turbo package; BMW also documents materially different 435d and 740Ld N57/8HP combinations, so select the donor by desired approval, output and turbo layout rather than mixing loose x30d/x35d/xDrive parts.
Buy and label a complete matched donor package: N57 long block with exact turbo system, intake, accessories, sump and emissions hardware; ZF 8HP with torque converter, flexplate, selector and mechatronics; engine/transmission harnesses, DDE, CAS/key or supported immobiliser solution, pedal, sensors, fuse/relay hardware and OBD components. Add one coherent Defender system for mounts/crossmember, LT230 adapter/input, cooling/charge air, fuel integration, downpipe/exhaust and wiring support. Before dismantling, record donor VIN, engine and transmission IDs, RWD versus xDrive output, DDE hardware/software, emissions approval data and Defender VIN/axle/LT230 details.
Status: SUPPORTED · Confidence 85%
Use an N57-specific Defender mount system and transmission crossmember selected for the exact 90/110/130 chassis and 8HP installation. The full commercial package includes engine mounts, brackets, transmission mount and crossmember; a separate 2015 Defender 110 build confirms bespoke engine and gearbox mounts in service. Mock up the complete engine, turbo/downpipe, front axle at full bump, steering, bonnet, bulkhead, radiator pack, LT230 and prop-shaft lines before final welding, and obtain the structural evidence plan before modifying the frame.
No reliable combination-specific information found on an N57D30- and Defender-90/110/130-specific solution for oil pan, oil pump, pickup tube and front axle or steering clearance.
A GS6-53BZ/DZ-to-LT230 adapter path is technically documented, but using it behind an N57 in a Defender is transferred evidence rather than a complete conversion route. The adapter instructions require output-shaft modification and precise sealing/alignment, while the N57-oriented vendor page merely lists GS6-53-to-LT230 among possible adaptations. Confirm the exact N57 bellhousing/input compatibility, donor gearbox code/ratios, torque capacity, starter, flywheel/clutch, engine position and approval before treating this as a project candidate.
No reliable combination-specific information found on an N57D30 Defender manual-gearbox solution for gearbox mount, crossmember and installed position.

Status: OPEN
No reliable combination-specific information found on an N57D30 Defender manual-gearbox solution for flywheel, clutch, release system, master/slave cylinder and starter combination.
Status: OPEN
Use a donor-matched ZF 8HP identified by exact type, output configuration and mechatronics rather than a generic '8HP'. BMW documents N57D30O1 and 435d applications with 8HP70, the complete Defender package supplies an N57 with 8HP, and a running 2015 Defender 110 uses a custom-programmed ZF eight-speed. Determine whether the donor transmission was RWD/2WD or xDrive before ordering the LT230 adapter, service it to current ZF/BMW data and validate ratios, cooling, selector, diagnostics and torque strategy as one system.
Status: VERIFIED · Confidence 92%
Use a matched N57 torque converter and flexplate with an adapter/input-shaft system explicitly selected for the exact 8HP rear output and LT230. The full package includes converter, flexplate, transfer-case adapter and input components; MW separately documents different RWD/2WD and xDrive adapter options, and the direct Defender 110 build confirms a bespoke billet adapter and shaft. Inspect runout, pilot/converter seating, spline engagement, sealing, fastener specification and LT230 input condition using the supplied instructions; do not mix shafts or plates between vendors.
Status: VERIFIED · Confidence 90%
Use the N57/8HP Defender transmission mount and crossmember from one coherent conversion system, with the engine mounts and LT230 position established together. The full kit includes both components and a direct Defender 110 build confirms custom engine and gearbox mounts. Establish driveline angles, tunnel/seatbox clearance, service access, exhaust position, transfer-case controls and front/rear prop-shaft geometry before final drilling or welding; 90/110/130 dimensions are not interchangeable assumptions.
Status: VERIFIED · Confidence 86%
Retaining the LT230 preserves its front and rear output architecture, but it does not prove that any original prop shaft retains correct length or joint angle after the N57/8HP installation. A direct Defender 110 build confirms 8HP-to-LT230 operation, and Land Rover sources identify LT230 Defender applications and centre-differential function. With mounts fully loaded, measure each wheelbase/build for flange pattern, compressed/extended length, slip travel, phasing, universal-joint angle, full-bump/droop clearance and high-speed balance; inspect or upgrade shafts and axle components according to measured torque and speed.
Status: SUPPORTED · Confidence 76%
Use the transmission controller, mechatronics, selector and engine-torque messaging as a matched N57/8HP system. The complete Defender package includes selector, transmission controller, TCU and transmission harness; the direct Defender 110 build reports custom 8HP programming, ECU/CAN integration and an air-operated LT230 high/low/diff-lock control. Treat the latter as one build example, not a universal requirement. Validate start authorization, PRND, brake interlock, reverse lights, torque reduction, limp mode, temperature, diagnostics and transfer-case indication before road use.
Status: VERIFIED · Confidence 90%
No reliable combination-specific information found on an N57D30 Defender manual-gearbox solution with documented driveshaft lengths, flanges, slip-joint travel and joint angles.
Retain the LT230 only after identifying its serial prefix, high-range ratio, condition and input arrangement, then audit both axle differentials, half-shafts, hubs and prop shafts for the selected N57 torque and use. The documented automatic adapters connect N57/8HP to LT230, and Land Rover material confirms Defender LT230T applications; the transfer-case overview explains the lockable centre differential and ratio variation. No axle-ratio or differential upgrade can be selected from 'Defender 90/110/130' alone. Verify front/rear final-drive match, centre-differential function, lubrication, backlash, speed signal and low-range/diff-lock controls.
Status: SUPPORTED · Confidence 80%
Retain the complete donor high-pressure common-rail engine hardware and design the Defender low-pressure supply, return, filtration and tank venting around the exact donor specification. The N57 Defender kit includes fuel-integration components and a filter solution, while BMW documents common-rail direct injection for the cited N57 variants. Do not infer pump pressure, line size or lift-pump capacity from a generic N57 label; use donor service data, prove clean supply and return flow under load, and pressure/leak-test every modified low-pressure connection.
Status: SUPPORTED · Confidence 70%
Use an N57/8HP Defender cooling package that treats engine coolant, charge air and transmission oil as one installation. The commercial 90/110/130 package lists radiator, hoses, expansion-tank solution, intercooler and optional transmission cooler; the direct Defender 110 build uses a bespoke radiator/intercooler pack. Preserve a high-point fill/bleed strategy, donor thermostat and sensor logic, adequate fan control and protected hose routing, then prove stable temperature at idle, road load, low-range load and hot restart. Radiator dimensions and fan current remain project-specific.
Use a donor-variant-matched charge-air system packaged for the Defender grille, radiator, bonnet and steering layout. The full 90/110/130 kit includes an intercooler and pipework, and the direct 2015 Defender 110 build uses a bespoke Allisport intercooler/radiator pack. Size and route the system for the exact single- or multi-stage turbo donor, retain sensor locations, add abrasion/heat protection, and pressure-test while checking axle articulation, fan, bonnet and hose movement; no dimensions are transferable between builds without measurement.
Use an N57-specific turbo outlet/downpipe and fabricate the remaining catalyst/DPF/SCR-compatible exhaust around the exact mount angle, wheelbase, chassis generation and approval plan. The full kit includes a downpipe and integration parts; the direct Defender 110 build uses a complete custom 3-inch system. Demand Engineering warns that N57 has a larger V-band connection and that small engine-angle differences can move the rear exhaust substantially, so an M57 or different-mount system is not a fit claim. Verify oxygen/temperature/pressure sensors, emissions hardware, heat shielding, hangers, floor and axle clearance, noise and regeneration temperatures.
Keep the exact N57 DDE, engine harness, 8HP mechatronics/TCU strategy, selector, electronic pedal, sensors and immobiliser data matched. The complete kit includes ECU, TCU, engine/transmission harnesses, pedal and OBD provision; a running Defender 110 build confirms custom ECU mapping, CAN integration and a bespoke harness. Because documented N57 applications use different DDE hardware such as EDC17CP09 and EDC17CP45, validate every pin, CAN message, power feed, ground, wake-up and diagnostic path against the donor VIN and actual modules; do not buy a generic 'N57 loom'.
Use the kit's documented immobiliser solution or retain a matched donor DDE/CAS/key set and commission any data transfer for the exact DDE. EDC17CP09 cloning documentation identifies ISN/immobiliser data, VIN, injector coding and adaptations; another N57 service documents EDC17CP45, so module identity must be confirmed physically and diagnostically. Define tachometer, coolant warning/gauge, oil-pressure warning, charging lamp, speed source, PRND/selector display, low-range/diff-lock indication, MIL and OBD functions individually, then verify failsafe behaviour and diagnostic access before road use.
Status: SUPPORTED · Confidence 80%
Rebuild the Defender chassis first, then engineer brakes, tyres, springs, dampers, anti-roll bars, bushes and alignment for measured axle loads, N57 torque, attainable speed, towing and off-road use. Land Rover's own higher-performance 90/110 upgrade method combines revised springs/dampers/anti-roll bars with uprated discs, pads and calipers and validates fast-road/braking targets; it is not an N57 prescription and does not cover the 130. TÜV guidance states that increased power may require stronger brakes and adapted suspension. Agree brake-performance, wheel/tyre, axle-load and stability evidence before selecting parts.
Status: SUPPORTED · Confidence 78%
Recurring project risks are treating N57D30 as one engine; buying the wrong RWD versus xDrive 8HP adapter; mixing converter, flexplate, adapter shaft or instructions between vendors; finalising mounts before checking front-axle, steering, sump, turbo/downpipe and bonnet clearance; assuming an M57 sump or exhaust fits N57; accepting original prop shafts without plunge/angle measurement; mismatching DDE, CAS/key, injectors, harness and software; omitting OBD and fail-safe functions; undersizing radiator, intercooler or 8HP cooling; removing donor emissions hardware before the German evidence plan; and increasing torque/speed without brake, tyre, axle and LT230 condition checks. Schaeffler documents a revised N57-family chain tensioner, so identify the exact current catalog assignment and inspect cold-start behaviour rather than declaring every N57 defective. Check the donor VIN for open campaigns with BMW; the code-specific EGR documents found in search were not reachable and are not used as factual recall evidence here.
Status: SUPPORTED · Confidence 84%
Technically feasible: commercial 90/110/130 N57/8HP packages, an independent specialist claiming the first Defender N57/8HP conversion, and a detailed running 2015 Defender 110 build all exist. German road approval remains conditional and project-specific because no cited source supplies a German approval certificate for the complete N57D30-to-Defender combination. Before fabrication, agree the exact donor/VIN, power and emissions level, retained catalyst/DPF/SCR/OBD, noise, cooling, frame and mount work, axle loads, brakes, steering, tyres, prop shafts, LT230/axles and interacting modifications with the responsible expert, then preserve material, welding, parts and test documentation.
Status: SUPPORTED · Confidence 84%
Germany, as of 31.07.2026: for the N57D30 conversion in the classic Land Rover Defender 90/110/130, no test certificate valid for the complete combination is available in the sources reachable here. TUV Rheinland therefore describes case-by-case assessment; only with a positive expert report can the competent authority issue an individual operating permit (Einzelbetriebserlaubnis). Where interactions are not covered by an existing report, TUV SUD names re-issue under § 19 (2) in conjunction with § 21 StVZO, warns that the Betriebserlaubnis may lapse in the event of danger or worsened emissions and noise behaviour, and refers to VdTUEV-Merkblatt 751 for increased output. Before buying parts and before welding or chassis work, the following must be agreed in writing with a competent expert: first registration and VIN, the exact N57 suffix and donor, output, emissions stage, complete exhaust after-treatment and OBD, noise, cooling, fuel, engine and gearbox mounts, axle loads, steering, LT230 and driveshafts, brakes, suspension, and wheels and tyres. The federal portal requires an expert report and correction of the vehicle documents for technical modifications subject to registration. For an H-Kennzeichen, TUV Rheinland does name period conversions within ten years of first registration; the detailed TUV SUD requirements catalogue, however, permits engine and gearbox only as original or from the vehicle model range. A BMW N57 is not a Defender model-range engine, so no positive H eligibility is claimed here. Normal registration and H assessment remain separate decisions.
