I need an engine for my 02 Stilo JTD, and have found a complete 02 Multipla JTD I could use for my own Multipla too , so are they the same engines?

I can tell you they use exactly the same turbo as I put a multipla turbo on my 115hp JTD stilo.
If it is a similar HP and similar year they are almost certainly the same. You should keep your original injectors, fuel pump etc to avoid any issues with putting different ones in. I think the only difference between the 110 hp and 115 hp is different injectors and a remap.

John,
Thanks for that, the Multipla I have in mind is 110hp and my Stilo is 115hp, so my concern was how different it was. I have all the ancillaries still, but not the turbo as it is knackered.
Cheers
Terry
