JE MotorWorks is the most experienced Land Rover & Range Rover tuning and modifying specialist in the world, from which has evolved an additional range of performance and dynamics enhancement for V8-engined Jaguars, Rover V8-engined Marcos, Morgan, Rover, TVR, Westfield, plus Roush V8 installations in suitable cars.
From day-to-day enhancement to ground-up bespoke design, engineering and build for the world’s most discerning Land Rover & Range Rover owners, as well as Jaguar V8- and Rover V8-engined cars, we can completely change the way a vehicle performs, from ironing out age-old inherent design niggles with bolt-on-and-play upgrades to powerplants ranging from hybrid and low-emission petrol engines through to tarmac-warping JLR supercharged V8s and high-torque diesels. We make the cars we enhance go, stop and handle like nobody else can. And look like it too.
Owner, enthusiast and motorsport performance & dynamics enhancement and restoration for Land Rover & Range Rover, V8-engined Jaguars, and Rover V8-engined Marcos, Morgan, Rover, TVR, Westfield, plus Roush V8 installations.
ECU Re-Map Tune and Tune+
We have extensive experience in completely changing the way a Defender 2.2 TDCi, 2.4 TDCi and 2.5 TD5 performs. For instance, on a 2.2 TDCi, our basic Tune takes power from 122bhp to 160bhp, torque from 360Nm to 454Nm, and The Tune+ to 183bhp/486Nm. Depending upon model and choice of Tune, prices range between £475 and £1380 all inclusive of VAT.
Our 3.2 TDi5 conversion, available on post-1999 Defenders, involves installation of 3.2 in-line 5-cylinder Ford power unit featuring variable vane turbo, JE 3.2-specific intercooler and JE-designed ITG induction system, all controlled by a bespoke ECU. Output: Approx 228bhp at 3300rpm, torque 576Nm at 2300rpm, with 430Nm available at 1600rpm. Transmission is either heavy duty Ford 6-speed manual or JE-developed Ford 6-speed Tiptronic auto, and includes a JE-designed centre console to accommodate. We also recommend and install strengthened prop-shafts; for Puma Manual £23,400; automatic £27,000. For Td5 Defender it costs more, because there is more to change – please enquire.
Our V8 conversations include Rover V8 4.5 (originally 3.5, 3.9 or 4.2), 4.8 or 5.0 litre (originally 4.0 or 4.6) engines, and, depending upon whether carburettors or fuel injection are specified on the Rover V8, a reliable 250-350bhp, and 400-450Nm, and for motorsport, we can go to 420bhp. JLR and Roush V8 installations for the Defender take matters into an entirely different dimension with outputs of up to 650bhp and 800Nm.
Defender 2.3 Ecoboost
Future proof your Defender. Current-day demands dictate that every vehicle range needs to have a model that pushes emissions and economy to the fore, even if that’s a relative concept when it comes to Defender. But a combination of JE know-how and engineering capability, and the availability of increasingly-impressive OE manufacturer powerplants, has led to our latest development for the Defender, JE’s Petrol 2.3 GDiT.
Based on the Ford Mustang 2.3 litre EcoBoost engine, our 2.3 Gasoline Direct Injection Turbo engine is very quiet and smooth, but gives a very responsive drive from 307 bhp and 432 Nm. Your Defender can be legally certified as a petrol vehicle, with excellent performance and good fuel economy. Manual or Auto gearbox available. Taking the original (Puma 2.4 or 2.2) powerplant in exchange – is priced from £17,160 Including VAT (Manual, no air-conditioning). The inclusion of a Tiptronic 6-speed auto (JE retain your original gearbox in exchange), and incorporating your existing air-conditioning , brings the price up to £27,000 including VAT.
If you have a TD5, it is more complicated, but possible, please contact us.
We can make considerable improvements in the performance of your Range Rover. For instance, a Tune for a 3.0TD6 (2002-07) will take it from 173bhp to 218bhp, and 390Nm to 488Nm. The price is £552. Meanwhile, we can take a 2012-on 5.0 Supercharged petrol to 532bhp/646Nm from 510bhp/625Nm. Price is £1020. Fundamentally, we can significantly enhance the performance of any Range Rover model, petrol or diesel.
Whatever we can do for a Range Rover, we can also do for a Range Rover Sport. That means considerable improvements in performance. For instance, a Tune for a 2.7 TDV6 (2005-10) will take it from 197bhp to 235bhp, and 3440Nm to 575Nm. The price is £594. Meanwhile, we can take a 2012-on 5.0 Supercharged petrol to 532bhp/646Nm from 510bhp/625Nm. Price is £1020. Fundamentally, we can considerably enhance the performance of any Range Rover model, petrol or diesel.
The Discovery is about practicality and capability. Towing is an important consideration. £474 invested in a Tune for a Discovery 2 2.5 TD5 (2002-05) will take it from 135bhp/340Nm to 170bhp/375Nm. At the other end of the spectrum, we can take a Discovery 4 (2012+) from 255bhp/600Nm to 285bhp/715Nm for £834. Meanwhile, with the Discovery Sport 2.2 SD4 we can move things on from 190bhp/420Nm to 233bhp/495Nm – cost is £714.
Such is the nature of the design of the Range Rover Classic that we are not restricted to the range of enhancements and tunes we can provide because it was not originally designed with sophisticated electronics. This means getting different components “talking” to one another via ECUs, which can otherwise be time-consuming, is less of an issue. Just about any V8 can be installed in a Classic.
Our V8 conversations include Rover V8 4.5 (originally 3.5, 3.9 or 4.2), 4.8 or 5.0 litre (originally 4.0 or 4.6) engines, and, depending upon whether carburettors or fuel injection are specified on the Rover V8, a reliable 250-350bhp, and 400-450Nm. JLR and Roush V8 installations take matters into an entirely different dimension with outputs of up to 650bhp and 800Nm. A range of gearboxes can be mated to the powerplants, including the JE-developed Ford 6-speed Tiptronic to the Rover V8. These are very much bespoke installations, and we would need to meet with you to discuss package and price.
The Evoque is about fun. More power and torque, more fun. For the 2.2 SD4 we can move things on from 190bhp/420Nm to 233bhp/495Nm – cost is £714. For the 2.0SI4 our Tune means 240bhp becomes 265bhp and 340 Nm ups to 380 Nm. The Tune includes a JE developed performance ECU remap and to ensure maximum air flow we also include an ITG performance air filter element, also £714. Fantastic value giving your earlier spec Evoque current spec performance.
In many circles, Freelander is the new workhorse, a go-to vehicle for outdoors-types, country life, boating and equestrianism. More grunt, more offroad and towing capability. For the Freelander 2 2.2 SD4 we can move things on from 190bhp/420Nm to 233bhp/495Nm – cost is £714. On a 2006-14 2.2 TD4, our basic Tune takes power from 150bhp to 180bhp, torque from 420Nm to 455Nm for £475.
We make Defenders stop, ride and handle in a manner few would think possible. A Defender will never be a premium saloon in terms of road dynamics, but we have decades of experience changing driver and passenger expectation in environments as varied as race tracks and urban streets. That expertise translates into an ability to understand and address similar issues across a range of other vehicles.
Designed to enhance the Defender’s behaviour on the road, JE’s Dynamic Suspension Kits employ our own lowering springs and anti-roll bars, alongside performance dampers from Fox Racing. Combined, these upgrades transform handling through greatly reduced body roll and much-improved damping, resulting in increased comfort. Our Defender 90 kit includes 30mm lowering springs front & rear which feature a softer spring rating to improve ride comfort, while our 110 kits feature lowered rear springs which help give the car a less nose-heavy look.
Our Performance Kit includes a set of Fox Performance Monotube Dampers valved to JE spec, JE Anti-Roll Bars Front & Rear, JE 30mm Lowering Spring (Rear only on Defender 110). Supplied: £1590. Supplied and fitted £2100. Our Supersport Kit includes the same package, but upgrades to Fox Supersport Dampers featuring remote reservoirs on rear valved to JE spec £1830 supplied; £2340 supplied and fitted.
It’s indicative of our undersatanding of Defenders that we know it is the smallest thing that can make the biggest difference to the Defender driving experience. How many of us have cursed the standard handbrake? We replace the awkward Defender handbrake with a conveniently mounted switch to help free up much needed space in the driver’s footwell. It operates the factory fitted transmission handbrake at the press of a button. Supplied and fitted £817.20.
While at the business end of the brake pedal the JE / AP Racing Big Brake kit -front – developed by our in-house engineers, utilises AP Racing 6 piston callipers, 362mm grooved and vented discs and high performance brake pads for maximum stopping power. Supplied: £3240; supplied and fitted: £3594.
Range Rover suspension tweaks need to be the best. We consider the best to be the Startech Air Suspension Lowering Module at £1500 supplied and fitted on both L322 models, 2002 – 2012, and L405 2013 on.
Range Rover is in a league of its own in terms of potential performance upgrades. We carefully match the brakes to the performance of the car, with options from AP Racing and Brembo. Once we’ve spoken to you about the spec of your Range Rover, we’ll be able to advise on what will work best for it – and you.
Range Rover Sport already has pretty sophisticated suspension. We give it a sportier character with a Startech Air Suspension Lowering Module, (L320, 2010 – 2013), TUV Approved, at £1422. supplied and fitted. For post-2014 cars we also fit the Startech Air Suspension Lowering Module – L494 models – £4404 supplied and fitted.
Brembo is one of our favourites at JE; for the Range Rover Sport 2005-2014 we recommend a front brake upgrade kit, utilising Brembo callipers, discs and high performance brake pads for maximum stopping power and outstanding pedal feel. Supplied: £3312; supplied and fitted: £3720.
Discovery isn’t a sports car, but it is a favourite for towing. Immense pulling power means a need for immense stopping power, hence our Brembo front brake upgrade kit with Brembo callipers, discs and high performance brake pads for maximum effectiveness and excellent pedal feel. Supplied: £3312; supplied and fitted: £3720.
We help Evoque into hot-hatch tarritory with Startech lowering springs, dropping ride height by 30mm, helping reduce body roll and giving a sharper steering response. Made by Startech in Germany they are fully TUV approved and come with a comprehensive 3 year warranty. Supplied: £460; Supplied and fitted: £876.
Evoque is deceptively dynamic. Brakes are the icing on the cake. The JE AP Racing Big Brake Kit, installed up front and developed by our in-house engineers, utilises AP Racing 6 piston callipers, 362mm grooved discs and high performance brake pads to ensure those dynamics are reined in when they need to be. £2700 supplied; £2995 supplied and fitted.
6 Speed Automatic Gearbox Conversion
We can design, build or adapt virtually any component that transfers or manages power or torque between flywheel and wheel hub. Two key, and typical, components are the JE-developed 6-speed Tiptronic auto gearbox for 2.4 and 2.2 Puma engined Defender @ £9700.00 plus VAT fitted, including electronic gear shift lever and trimmed cubby box housing. Additional applications are also available for other Land Rover models (including Range Rover Classic) P.O.A.
TD5 transfer box upgrade is available which reduces engine speed by 400rpm at 70mph. This is priced at £738 supplied, and £1140 supplied and fitted, and is an exchange item. We also design and build uprated propshafts and driveshafts, and adaptor kits to allow retention of original Land Rover 4×4 systems when installing upgraded gearboxes.
Working with Range Rover Classic restoration partners Kingsley Cars, we can bring the Range Rover Classic ownership and driving experience to almost modern-day standards. While Kingsley restores and aesthetically enhances early Range Rovers, as well as gives them vastly improved dynamics, JE has developed a modern-day 6-speed Tiptronic auto conversion which completely changes the way gear changes are experienced, and power transferred from standard or enhanced Rover V8s to the road. Price from £11,483 fitted.
As a go-to engineering and development specialist with decades of experience in road and competition drivetrains, JE has amassed great human experience and made significant investment in advanced design and production equipment.
It’s indicative of our undersatanding of Defenders means it’s the smallest thing that can make the biggest difference to the Defender driving experiencxe. How many of us have cursed the standard handbrake? We replace the awkward Defender handbrake with a conveniently mounted switch to help free up much needed space in the driver’s footwell. It operates the standard differential handbrake at the press of a button. Supplied and fitted £817.20.
Much of a Defender’s design is based on basic function. Standard wiper systems front and rear are typical. This JE-designed kit provides an intermittent function for the rear wiper, which also wipes three times after washing, and a variable speed intermittent function for the front wipers, and replaces the standard Defender single front windscreen wash nozzle with two wide-angle washer jets fitted to bonnet: £300 supplied, and £654 supplied and fitted.
Nobody needs telling that a Defender is not and will never be limousine whisper-quiet. But we do know how to make a huge improvement in refinement.
Defender 90 Stage 1 Noise Reduction
Stage 1 includes Noise Killer foam material applied to entire floor, seat box, transmission tunnel, rear wheel arches and rear side panels. £1100 plus VAT fitted.
Defender 90 Stage 2 Noise Reduction
Stage 2 adds Dynamat panels placed strategically around the interior to reduce resonance in the thin metal panels. Dynaliner foam material is also added to the inside of the roof panels to reduce noise and help insulate the cabin. Soundproofing also applied to the bonnet. £1990 plus VAT fitted
Defender 110 Stage 1 Noise Reduction
Stage 1 includes Noise Killer foam material applied to entire floor, seat box, transmission tunnel, rear wheel arches and rear side panels. £1400 plus VAT fitted
Defender 110 Stage 2 Noise Reduction
Stage 2 adds Dynamat panels placed strategically around the interior to reduce resonance in the thin metal panels. Dynaliner foam material is also added to the inside of the roof panels to reduce noise and help insulate the cabin. Soundproofing also applied to the bonnet £2300 plus VAT
We don’t just suppress and manage noise, we also eliminate it at its source. The TD5 transfer box upgrade reduces engine speed by 400rpm at 70mph. This is priced at £738 supplied, and £1140 supplied and fitted, and is an exchange item.
JE enhances, tunes and upgrades a variety of Jaguar Land Rover, Ford, Marcos, Morgan, Range Rover Classic, TVR and Westfield vehicles, for road and motorsport, and provides consultancy and feasibility study to the automotive industry.
