Spotted this on a trailer at a servo; on its way to the wreckers. Spoke to the owner and $50 later, I owned a sigma; delivered to my door.
This is the old beast

its completely granny spec; right down to the stickers, radio, roof racks, spoiler and 14" hubcaps.

As the story goes; it was parked up 12 years ago with a blown head gasket.
Obviously; being parked up hasnt done it many favors; but now, armed with a car that I've always wanted; i get the chance to do one of the builds I've wanted to do for a long time: build a sleeper.
As we all know; when it comes to sigmas, the go to engine swaps are either; small block ford, V6 commy, Astron EFI (or turbo) and 4g63.
I've decided to try something just a little bit different....
Converting to a TURBO DIESEL WAGON!
Using a Mitsi 4d56t 2.5 diesel from a Pajero.
This whole theory is based on the fact that old Pajero's used wide block 2.6 engines as well as 2.5 diesels.
When I previously did the same swap in my old petrol Paj, I realised that the petrol and diesels shared the same engine mounts, clutch dimensions, sump gaskets and bellhousing pattern. This gave me the idea to whack a dirty turbo diesel into a sigma to replace a worn out 2.6.
Didnt waste any time ripping the old astron out.

And in with the dummy engine (spare cracked block) for a test fit.

And,as suspected, its a direct fit.
I will need to swap to the petrol (shallow) sump and modify the diesel oil pickup tube; as the deeper pan fouls on the steering components.
obviously, being a mitsi diesel, this wont really be a powerhouse; but with roughly the same power and a bit more torque than a 2.6L.
The real win is in the smooth power delivery of the diesel; as opposed to the hopeless carby which usually suffers from infinitely variable tuning; copious vacuum leaks; and a flat spot between idle and the redline

Of course; the obvious reason for building something like this, is to watch people reaction as the see nanna's old sigma wagon rolling coal at the traffic lights; sounding like a mack truck.
I will endeavour to keep this thread up to date as more progress occurs.
Feels great to finally be part of the sigma crowd. I look forward to any comments or questions about this setup.
cheers
