anyone had any experiences with the niva turbo cartridges on ebay? just type in 'niva jtd turbo cartridge' and it should come up top of search..
just bought a 05 doblo jtd which smokes like heck ,pulled i/c hose off and it is full of oil so id say the turbo has had it.Engine ran away when i started it - running off the oil from the turbo but slowed down and thankfully didnt end in a seized engine.

or which other turbos fit so i can keep an eye out..
cheers

I can't confirm for sure but the 1.9 JTD is used quite widely on the Fiat range, Multipla, Stilo, Punto, Bravo etc.
Have a look through ePER to cross reference part numbers.
