1980 Scorp advice + pics

Post by KiNGXAVY »

I have a few questions about the car.

Are there any quick fixes/mods to get a little more power out of this beast? (Engine is a 4G54)
I am also after a Power Steering belt, but I am unsure on what the part could be. I had a look around on the net the number (13A0750) as a part number seems to be the one. I just wanted to confirm that.
I read that the coin box beneath the radio is NOT Scorpion specific, would that mean I could obtain one from a Sigma or similar model and it would fit?

Any help is much appreciated.

Cheers.

**EDIT** Added some pics to this post.

Hi KiNGXAVY, what condition is the scorpion in? A good tune up is a start, putting a kit through the carby will help return the engine to better performance. After that, it's standard stuff - headers and sports exhaust, head work, fuel delivery upgrade (bigger carby, EFI mod or have a look at something different like modded quad bike carbies - http://www.sigma-galant.com/viewtopic.php?f=93&t=7524 ). Elimination of the balance shafts are also popular with Astron engines. Other option is sourcing a turbo engine like the VR4 for an engine install. It begins with what you can do and what the $$$ allow for. Use the search engine to get ideas on what you want out of it - http://www.sigma-galant.com/search.php
Good luck and post pics for us! :thumpsup:

Cheers geezer.

Its in fairly good condition, a bit hard to start in the morning but that's about it.

The body is quite straight for its age, I'm in the middle of painting the vinyl strip near the rear windscreen because there was rust underneath.

I've heard a Weber 34ADM bolts straight onto the engine, would this be right?

Thanks in advance

It's not a straight bolt in but only requires an adapter to mount it onto a stock manifold (easy to do) -

It however will require sorting out of fuel and vacuum lines, accelerator cable mounting and deletion of a coolant circulation line to get it running. If you're competent with a spanner it's not out of your scope to set it up. 8-)

Welcome to the site KiNGXAVY as mentioned above larger carby exhaust general tune and getting the engine in good working order will help with performance.
The power steering belt if you remove the belt and take it to your local repco or similar store they should be able to match one up for you.
It's four and a half hammers across!!!

Cheers foxpsi.

When I purchased the car, it didn't come with one attached, but I have ordered one online which should hopefully work.

And if it doesn't fit, I can just sell it :P

Run a length of string around the pulleys and you will get a measurement. Take this to your local auot pasrts shop with a tape measure and away you go.

but seriously power steering only came out as an option as far as I am aware on the GH scorps, the power steering unit should be on the drivers side of the engine below your exhaust to the front of the engine. pics of your bay will help you will probably need to take off the other belts to access it, where I have seen them they run off the main crank pulley. where abouts are you? Sigma manuals will have the details on how to change the belt because the engines are almost identical.

Look for a smaller pulley (closer to the timing cover) behind the one with the waterpump/alternator belt.
If not one there, have to source one.

You are going to need more than a belt to get the power steering working on that car mate.

sorry dude, shouldn't be taking the piss out of new members. anyway more power. probably why they disconnected the air con belt. there is a balance shaft removal tutorial here somewhere, removing those will give you a little more power/response. so will replacing the clutch fan with a thermo. I have the same scorp and run a 34adm it works well. check if your secondary vacuum diaphragm is working if not replace it (or if your dodgy like me chuck a rubber band or two on it) extractors will help.
all the info on modding the engine is in the engine section

I now own this beast. I will be needing a few bits once my finances recover.
I think it might be the only one in nz

Greets to you bigfoot. Has the car changed much since this thread was last updated? As you can see there was a lot of talk on what was going to happen to the Scorpion - when you figure out how to post pics, get your own thread rolling :)

Sorry to hijack this thread, but is it me or is the accelerator bracket mounted upside down? Is it because this particular carby has counter-clockwise throttle operation (opposite to the Sigma's)? If so please post more photos as I'm trying to install one like this and need to know a bit more on how to get the throttle connected to work the opposite way...
