Look what I found! Apparently it's to fit two Stromberg carbies onto a 6G72 for Sprintcar racing!

Megajolt?

Humm, interesting, apparently the ignition control modules are all separate to the ECU, this will be fun to wire up!

I was so excited about this engine swap I could hardly sleep last night! But I think I've hit a bit of a snag. Do any of the 6G72 engines have the ignition module built into the distribuitor or is it all built into the ECU? The problem is if the dizzy is run by the ECU, how am I going to run it if I...

Ok, it's been a while between drinks sorta speak. I'm seriously thinking about a RWD 6G72 conversion now, but I'm going to do two different things: use a Ford C4 auto (using a Bill Hincher bell housing) and convert the engine from MPFi to a 350 Holey carb! My inspiration for the carby idea comes fro...

I'm very keen on one of these 6G72 RWD C4 auto bell housings. I have left you a PM

Hi Bill, any news on the 6G72 bell housing? I'm very keen in fitting a 6G72 to my car, but I would rather fit a C4 or other automatic transmission. Could you please help me?

Well since my old original 2 litre engine is simply not powerful enough, I'm seriously considering fitting a 6G72 with a 350 Holley carby and auto trans. Does anyone know if the 2WD V6 Tritons ever came out with a 2WD auto trans? And do the Pajero and Triton V6 4WD auto transmissions have a bell hou...

Hi Abaddon, have a look at my blog, I'm slowly improving my stock 2 litre 1978 Sigma SE 3speed auto! The engine so far is stock internally, but to take advantage of the standard high compression ratio (9.5:1), I installed twin Solex carbies and a mild Crow cam. The car feels much more lively and pul...

Ok, after some research, I found some more info from my workshop manuals, Wikipedia ( http://en.wikipedia.org/wiki/Mitsubishi_Astron_engine ) and Sigma Turbo Register ( http://www.sigmaturbo.com/Specifications.htm ). The four Astron engines we will be looking at today are: 4G51, 4G52 (and G52B), 4G5...

Can an Astron 2 litre block be bored and stroked to 2.6? Stroking should be easy just by fitting a 2.6 crank i think, but can it be bored out to 2.6 or more? Are 2 litre Astron blocks the same as 2.6 ones but with more meat between the cylinders on the 2 litre ones? I decided to keep the original As...

That's right, this is the one, but now im thinking it's in such good condition that i might just modify the stock parts and pull the engine apart and bore and stroke it to 2.6 but up the compression to at least 10:1 and work the head too. I already have a nice high-flo 2 and 1/4 inch exhaust with ex...

http://3.bp.blogspot.com/-4PwiZYTwMec/T3d091Hn47I/AAAAAAAACNw/epIiRgZBsHQ/s400/IMAG0061.jpg The golden GE Sigma SE is coming along quite nicely. Engine is all back together and timming is now adjusted properly. The car runs so much better and is so much more powerful now that it has a new head-gask...

Where can i buy the valve needles and seats for these rare twin solexes in Australia? Is that going to fix the issue of it being a pig when cold? The manual chokes arent connected either so i guess thats not helping either

I actually stumbled across two sets for sale on Ebay from a Valiant, but they are the same as on the Sigmas: http://www.ebay.com.au/itm/CHRYSLER-Valiant-CHARGER-VK-CL-INDICATOR-front-guard-top-1-BONUS-indicator-FREE-/370654892040?pt=AU_Car_Parts_Accessories&hash=item564cc0d008 http://www.ebay.co...

Wow talk about a bit of nostalgia! My name is Fabio and I can't believe this site is still going after all this time! We created a monster!! And from very humble beginnings... I've always been a car-nut and my first car (which I still own) was a light blue GE Sigma SE I bought for $1200 back in Dece...

Ok, checked the timing, car was pretty hard to start, but once started it coughed and complained a bit and then started reving properly but still wouldn't idle. I kept it running and above 2000rpm so it wouldn't stall and also so the head-gasket would cook properly and after 5 minutes at 2000rpm it ...

It still amazes me how easily V8 engines fit into the Sigma engine bays, well much much easier than other old cars of similar size (Gemini, Mazda 929, etc). Keep up the good work!

Thanks mate, I was hoping someone would post a photo for me, I've got two different factory workshop manuals and I couldn't find any info on either regarding which way the dizzy rotor button should be pointing and I couldn't see any marks on the dizzy either. I was very tired the last time I looked ...

What about the dizzy on my stock-motor 1978 Astron 2000? What/where should my rotor button be pointing at when the engine is showing zero TDC on the crank pulley?

Head gasket changed and while I was at it, also fitted Crow Cams mild street cam! Tryed starting it for the first time last sunday after I finished putting it all back together but not sure if I put the distribuitor in the right gear! Can someone help? I checked the workshop manual but found no refe...

Not sure mate, I would like to know also. The only times in the past that I've changed them I swapped with some spare old working ones...

Here is the latest on my Sigma. I spent the entire weekend working on the engine to change the blown head-gasket (due to old age and inherit corrosion) and while I was at it, I also fitted the Crow Cams mild camshaft I bought. http://3.bp.blogspot.com/-483faQQnDlw/UF7aIIoDCXI/AAAAAAAACXk/Qv2WOdaQOmw...

If the distribuitors are different, use the original one from your car. I had ignition wiring issues when I fitted a big block GN Sigma 2.6 to my humble little GE Sigma (originally a narrow 2 litre).

Awesome! Please make sure you post photos and videos of it, especially after the 13B is fitted! I still plan to fit a 20B to my GE Sigma, can't wait to do that too!

Stop teasing us and post some photos

That's Sigma porn right there! More please!!

Any updates on this car? Would you be interested in selling it if you still have it? I'm trying to find my Hemi orange Sigma too, If anyone knows of the whereabouts of the car below please contact me via pm or email: 20bsigma@gmail.com. I really want to buy this car back as me and my dad did lots of...

Well it's been a while since I started this build topic on my blue GE Sigma SE. The sad thing is the car is just too far gone with rust, but I still can't bring myself to get rid of it, it holds far too many memories. But as I mentioned on my first post, I did have a Hemi Orange GE Sigma GL that me ...

Very cool project, make sure you post some before and after pics!
