Off-roading and heavy-duty SUV enthusiasts should definitely be familiar with the 2.5-litre inline four turbocharged diesel engine 4D56. Used in Mitsubishi off-roaders and vans since the 1980s, this engine has become a very respected motor among fans, drivers, and repair people alike.
This particular motor uses DOHC and has a turbocharger. Newer 4D56 models also come with an intercooler to boost power and efficiency. Depending on the exact variant, the 4D56 could develop 100 kW of power. The high compression ratio makes it suited for towing and off-roading. Most often, this engine is fitted to the L200 Mitsubishi pickup and a few other SUVs.
Overall, this engine is considered reliable, but the 4D56 can suffer from overheating and turbo problems. Buying a used motor from Orbi Motors could solve these issues.
