Even though you said "no v8 swaps or this or that" and what not.
It'd work out so much cheaper;
WK Statesman V8 | Cars, Vans & Utes | Gumtree Australia Grant Area - Mount Gambier | 1134982604
Spend another $2000-3000 on parts to make it work and you'd still spend about the same as what a replacement CRD will cost once it's turn key ready.
One door closes so another can open.
(also I have nothing to do with that for sale ad, I just quickly jumped on gumtree and that was the first one I saw)
