Dave and the boys did my conversion last year M57 330d, with mt82 into my 1998 300tdi and I’m extremely pleased with the whole conversion, fantastic torque, power and most of all for a landy reliability, I would highly recommend you give them a call, you won’t be disappointed 👍🏻👍🏻
Phil Hoggarth –
The M57 conversion is a great option for those looking for a daily driver. Lots more power and torque with better economy and refinement than standard. I had the full stage 3 conversion (circa 400hp) done by Dave and the team and 20k+ miles in I couldn’t recommend highly enough, still puts a smile on my face every time I drive it

I meet Dave and the Mahker team in April 2022 having researched engine conversions for my 64 plate Defender 90. I was sold by the enthusiasm and professionalism I saw when I visited Whitchurch. I had the M57 conversion completed and the 400bhp build is superb. I use the 90 as a daily driver, fuel economy and the drive is brilliant either on long motorway runs or going to the shops!!! It allows me to bring out my inner boy racer when I want to or be the sensible professional on the way to a client meeting. I cannot recommend this conversion and the Mahker team enough. What Dave and the team bring is something special in what they do and customer service. After 12000 miles the 90 drives like the day I picked it up.

I’ve got the full kit from Dave and his team, I did the conversion myself, first time and everything just worked, everything fitted as it should, quality of this kit isn’t even touchable by others in my opinion, I looked at all options and nothing matched,
I chose Mahker for a reason! Im 9k miles in now, it’s been absolutely hammered, ran up and down the country in all conditions and also pushed to the limit off road! From lanes to pay and play bogs, Hasn’t skipped a beat!
If you considering doing this conversion yourself don’t go anywhere else! It’s worth every penny! Such a helpful company, I’m pretty much lent on them to help me with what needed wiring and how, they helped no questions asked.
Top kit! If there was more then 5 stars to give I would.

My Defender 90 pickup is my daily work van. It goes to some properly inhospitable places and regularly carries a serious amount of kit and supplies. What I need from it is simple; it has to start, pull and get me home – every time.
Dave and the Mahker team fitted the M57 conversion to my 2.4 Puma Defender, and I’ve covered around 12,000 miles since. Fully loaded, it pulls strongly from low revs on the steep, rarely-used mountain tracks I use to reach the Snowdonian hillsides, where the old engine had to be worked hard. It does that without fuss and I don’t have that feeling of dread of “Is it going to breakdown up here?” that I had with the old Puma engine.
On the road it drives like a (very comfortable) car but with all the benefits of a Landy: the visibility, the off-road ability, the load carrying and the towing. I’ve seen 31mpg on a run, which I’m very happy with for a loaded work vehicle. It’s also a proper Wolf in sheep’s clothing. You’d be surprised how quickly a Defender can leave a dawdling tourist’s behind along the lanes when I just have to get on with my day.
The build is neat, well engineered, looks like its OEM and made to be used rather than looked at. But it does look great too and I’ll admit to being seen with the bonnet up showing an admiring farmer or two.
One honest note: putting used parts back onto any vehicle is never perfect and not without issues, and a few small niggles will turn up as you go. Dave and the boys have sorted every one of them with a smile. My advice is to set aside a contingency fund so you can get your vehicle properly “right”. That’s the nature of this kind of conversion, and I’d far rather deal with a team who still stand behind their work long after the bank transfer.
I’d recommend Mahker without hesitation.
