Hi guys, i've had a long look through the forum and I can't find any existing posts relating to this, please stop me if i've missed something. I've got a Citroen Relay 2005 with a 2.2 HDi engine. The engine has given up on and I want to replace it. I'm looking through the internet and finding a lot of engines from different Relays, I'm wondering which engines are possible to interchange with mine. For example, could I refit it with an engine from a 2004 Relay, or from a 2005 Relay but a 2.8 engine ... ? What are my options? Obviously I've clueless and any advice is useful.
