Not sure how to answer your question accurately as Peugeot is not my speciality. There are some wonderful people on here who will know what you need exactly, so just be patient, an answer will be available soon
It will be. The 1.1 was really meant for 106 consumption. There's a 1.6 HDi which is very nice indeed. I have no idea what else you'd need to do replacing a petrol engine with a diesel one though.
Standard tune is 110bhp but should remap to around 150 without too much difficulty.
im looking at getting the 1.6 petrol engine but dont know if i need to change the loom and ecu to run it ect but the diesel sound a good option but would prefer the petrol 1.6
