Just scanning the net just before bed, and found that
the Sigma Turbo
still exists, at least upto 2 years ago!
Nice to see that it's still around, well hopefully it hasn't disappeared in the last two years.

If your real desperate they had one at the birdwood motor museum in fairly good condition with the full body kit etc. I haven't been there for s while but its probably still there.

Reading the thread (within the link) it's mentioned that this is the car that was at the Birdwood museum - prior to ending up in the back of of an old warehouse.

That's the point. It's not any old Sigma Turbo, it's the one and only concept car. Not for the original, but a hi-po version by Mitsubishi, but with the fiberglass body work done by Alan Purvis.

Sorry chaps, I should have followed the link. I could be wrong but I reckon one of the guides at the museum told us that the concept car never actually received the turbo engines that Chrysler were experimenting with. Anyone able to confirm or shoot me down?

Not totally sure. I think I have a magazine with an article on this car, I'll have to dig it out and have another read.

That does line up with what others said on the link... Wouldn't be hard to fix that - A Starion 2l or US's Starion (Conquest) 2.6l turbo'd bolt in, else an EVO 2l with adapter plate would give it the go to match the looks

Stick with the period engine in this case.
Rad's right. The 2.6 L Starion engine was hugely under-rated. My good mate set a turbo one up properly in the mid 80's in his Scorpion and it smashed everything at the time.
For this Sigma, the 2.6 L turbo with aftermarket fuel injection I reckon.

Yeah my first car was a little Starion that I spent every spare minute and dollar on. After working the 2l and a few rebuilds later I ended up swapping the 2l for a US Starion 2.6, modifying TP magna fuel injection manifold to suit and everything else imaginable. Used to run high 13's and was alot of fun - as you say the 2.6l was very underrated. Lack of maintenance would cause the valve stem seals to wear out which was what gave them a bad name. I did however end up using a worked magna head instead of the starion one as the starions had the annoying jet valves which would stick open on worked engines at high RPM...

Why does every part need a modification or paint

Hi
Could keep it in its times (there sitll making the astron motor ) or
Mitsubishi 6G7 from the 380 3.8litre v6
Fitted with a twin turbo kit easy mod from a holden v6
4L60 holden gear bag
may be a r32 or 33 irs
And i think the 380 front end is an easy bolt in (not shore) mainly for the brakes

Now we're talking! Would make it pretty front-end heavy... fun none the less.

Hi
I dont think there wouls be much of a weight gain as the old motor was cast iron the replacment would be alloy i thing the gear box would be the greatest weight gain.
The rear tyres would also need to be enlarged to handle the power
