Had to replace the motor (easier and cheaper than rebuilding) as I wrecked the rings, it was using heaps of oil and had low compression.
Slight rust in the bottom of the front guards.
A few other minor problems that were generally because I done something stupid.
Easy to get parts for as everything is interchangeable with standard Sigma parts, only problem I have is it is impossible to buy a service manual for it in Australia.
I bought a Scorpion two and a half years ago and I resprayed it and did little things to it, but it still has a stock engine. I think it is the best car because I thought that it would just be a normal Sigma, but it isn't.
Performance in this car is good for stock because I had a drag with my mates 12A RX7, I was level from first, then in second and third he started pulling away, but from then onwards I stayed on his door.
My engine is in bad need of a rebuild, but it kills all stock 6 cylinder Commodores from the age of VC through to VK (not fuel injected), so keep doing more things on Scorpions because I can't find any web sites on them.
My name is Corey and I am 17, I bought a Scorpion about a year ago. It's sweet!! I want to do it up, but I don't know what to do, I want to put double Webers on it, with a performance cam, but I don't know if it's worth it. It's stock standard, other than the exhaust. It has a good stereo in it, with subs, amp, and so forth, but I was wondering what else there would be to do to a 2.6 Astron, like to make it off its head.
Well thanx man, hope to hear something back, bye!!!
Hi people.
Its really great to see that there is a web site dedicated to the scorpion or as me and my mates term it the "scorps".
I was really looking forward to viewing a photograph of this vehicle.
I am currently in the market to buy a scorpion for my girlfriend.
A mate at work is going over to europe and is selling his dark green scorpion to me for $350.I have had a drive and I consider it to be a very big 4 cylinder with extreme potential.
It is stock standard at the moment but before I hand the keys over to my girlfriend ill freshen it up with a new 2 pack respray of bright orange, ill throw some nice tight fitting mags with low profiles and buff up the interior at my mates re - trimmming delership.
I have also found that the darkest legal tint available on all the windows looks really "phat" and credible.
Ill propably also replace all the light covers with darker shades.
If she's lucky ill also fix the air conditioning, coz its on the blink.
Keep an eye it for it shell be cruisin around bankstown and liverpool in no time and no doubt this 20+ yr old car can still turn heads and mix it with the big boys.
Cool site.keep up the good work.
I had my 81 scorpion for 2 years but only recently put extractors + 2"sports system through. The other day I added a double webber carbie but are really looking for a 2.6 fuel injected engine from a magna. Anyone know if they fit and if not what has to be done???
Everybody should goto www.RPW.com.au and you will get all the tips you need. As for the magna engine no. Get an Astron 2 engine out of a GJ-GK scorpion and the get the latest magna head you can find. As they got newer the ports got bigger. This head will bolt straight on. Then get the inlet manifold off the magna cut the throttle body off and put it on the other end and you will have one of the strongest engines built. With turbo, no balance shafts, balanced bottom end, forged pistons, magna head and injection you will be able to produce 350hp at the treads no worrys.
I'm a big Scorpion fan. I have had many drags in my car (at the time of drags a stock 2.6 manual). Cars I have beaten include a 12A manual RX7, new Hyundai Accent, a few VL commodores, a new Lancer VR-X. I also used to run my mates VK Commodore EFI (with exhaust and extractors) all the time up to 160 km/h and it was basically even all the way. I blew the big end bearing not long ago and got a rebuild of the stock motor costing $2500. After putting 1500 km's on the new motor I took it down to the drags and ran a 17.5 with a 2.7 second 60 foot time. I should be getting around a 2.5 60foot time however this was good enough to beat some stock Civic's, Lancer's, and do smoke off some old Corolla's, Gemeni's, etc. I'm looking into making a Scorpion website. If anyone wants to chat to me or help me with the site send me an email to WReXy_STi@hotmail.com (yes I am a WRX fan but one day my scorpion will smoke WRX's :)
Quick, but not too quick. Has just got quicker. Bought a 32/36 weber (same as Holley 5200) and put it on, with some porting to the inlet manifold. Played around with the jets and now it goes a lot quicker.
Also I am now running electric fuel pumps, better ignition and thermo fan, all of which has helped, especially in allowing it to rev more.
The Astron series 1 and 2 engines as found in sigmas, scorpions and early model magnas are two of the best engines ever made. I have owned a GH sigma with the 2.6 Astron 1 engine, extractors, mild porting, webers, etc mated up to a 5spd Japanese gearbox. that car had no problem launching the front wheels and ran a best of 15.7 1/4 mile in street tyres. I had planned to put the motor and drivetrain into a Scorpion of a similar year and turbocharge the engine. The Scorpion, with neccesary mods and a bulletproof Astron turbo has the potential to be one of the quickest street cars around. I have since turned from this idea and just today I fit the 2.6 into a Mitsubishi l300 van. The torquey engine mated up to the low ratio 4 spd has produced a somewhat undriveable peoplemover. Even when I ride the clutch to hell and back I still can't take off without spinning the treads!. He, he!
Keep doing up those scorps!!! so far mine has done a best of 12.8 with traction problems... a good, all round solid car with a bit of tweaking :)
a TO4 helps!!!
They are certainly top cars. I have a 1984 Scorpion that is standard apart from having a 3.8 Fuel Injected V6 in it. It goes reasonably well and has beaten anything against it. It was a tough job getting it in and cost a fortune but it has resulted in an effective 'sleeper'. I'm sure there are faster Scorpions around, but not too many. They are the forgotten Mitsu- keep discussing them!

Hello, I bought a Scorpion. It has been driving great. Appart from a small flat spot due to timing it has been a joy to drive. Recentley it started cutting out under revs. Now it won't start after stopping on the freeway, she just died. Now it starts and idles when its cold. But will not rev or run. I have fuel in my filter running through, but won't drive engine stops does this sound like a carby problem. It's an Astron II. Is this a common thing with the car. It is mint and engine sweet before this. Will take to mechanic just curious. Been running standard unleaded. Thank you.
