## Resource

In this week's episode, Land Rover Monthly editor Martin Domoney grabs an hour with Ben Barker at Motor and Diesel Engineering. From the very early days of Perkins diesel converting classic Range Rovers to developing the latest complete drop-in conversion kits for all manner of Land Rover including fitting ULEZ-compliant petrol engines into Defenders. Ben mentions his early Land Rover One Ten County Station Wagon, which may well be giving its 2.25 petrol four-cylinder for rather more modern power, while the mods will remain fully reversible. The 300Tdi gets some serious upgrades at Motor and Diesel, with one of their most popular conversions being a conversion to 2.8 litres – more power and torque especially when combined with one of M&D's variable nozzle turbochargers. Ben is also quick to sing the praises of his Discovery 4 – on 170,000 miles on its original engine and driven hard every day, despite needing yet another park brake module... As always, we love to hear your stories and get your feedback and questions – send us an email on editorial@lrm.co.uk – and enjoy the episode.
