It lives again!
It lives again!
Hi there. I still drive my first car which I've had for just shy of 20 years. It's a 1978 Sigma Galant. When I bought it someone had already changed the motor for a 2litre version. Since then there's not a lot I haven't (had to) replace or rebuild.
My wife rang me the other night to say the handbrake had failed and she'd watched it roll down a hill and hit a house. But... from write off to on the road for $70 - you have to love 30 y.o cars. :-)
I found a set of 5 Sigma turbo rims many years ago and they now grace the arches. Thin rubber at the moment, but I may get excited again and go for wider boots whilst I'm fixing any other damage. I think it's time for a respray too. The motor is a G52B which I've balanced and stuck hi-comp pistons in; the cam has had a mild regrind too. The 5 speed is sounding a little tired and could be due for a rebuild.
The last time I rebuilt the top end I just threw on the head and inlet manifold from a 2.6l astron motor - I'm wondering if the Magna head with hydraulic lifters would be a straight swap... Hmmm....
Anyway, glad to have found this forum after many years of ownership.
Cheers,
Cam

Yep got to love these older Chysler sigmas I must have owned mine for 15 years but its been a CAMS log booked race car for 10 years this year.camB wrote:Hi there. I still drive my first car which I've had for just shy of 20 years. It's a 1978 Sigma Galant.

mine started life as an 1850 as well
the magna head although has the same bolt up pattern has much larger combution chambers and will drop the comp way to much
I was going to use one my self on a 2 Lt in the race sigma and found if you machine 3.5 mm
off the face the comp was back about std but then the top of the bore needed to be releved
a bit to clear the inlet valve
anyway I built a magna head to fit the 2Lt but burnt a hole in a piston at Caulder running it a bit lean
(mind you these days if I where to do a magna head to 2Lt I would look at a M8/9 head off a TS magna they run a smaller chamber )
from there I've run a 2.6 and never looked back
any way welcome to the forum

Thanks for welcome and informative replies people. I can see this is going to be my first stop whenever (sorry.. IF!) something goes wrong with the Mighty SIgma.

Re: It lives again!
Welcome to the site!
Cheater, just curious, what head did you have on a 2lt? (when you say try a M8/9 i'm guessing you mean the kidney yeah?)

Not a straight swap, but it isn't too difficult either. Makes for a lively little 2lt ;)camB wrote:I'm wondering if the Magna head with hydraulic lifters would be a straight swap... Hmmm....

Re: It lives again!
no the head I did for my 2Lt was a M4 magna machined 3.5 mm you could live with the combution chambers then ( had some comp ) and I had already sused out that the inlet valves just touched the bores as they opened81GL wrote:

not that that was a problem it only needs a little die grinding for clearance
as it was I updated to a 2.6 and ran the milled down head there
I did this work 9 years ago and if I did it now I would use a M8/9 as less material would need to come off the head - but remember 9 years ago it was hard enough to find M6 heads
I just ran the burret over a m8 head and it had 59 cc compared to 70 cc for other other astron 2 heads both unmachined

Re: It lives again!
There's a TS Magna head on ebay at the moment. Item 150341356265.
Looking at the top and bottom - it looks to be an exact match. Do my extractors from the 2l fit on to the Magna studs? And the head and inlet manifold on my 2l are actually off a 2.6l auto (seemed easier and cheaper than repairing my head) - would they match the inlet manifold studs on the Magna head? Distributor too?
Thanks guys for the input.

Re: It lives again!
camB, on any Magna head, the exhaust stud pattern is the same, but..... the inlet side is different. Easier to use an Astron I head. ;)
I'm here for a good time, not a long time !

Re: It lives again!
Thought I'd show the damage. :-)
Oops...
Not bad for down a hill into a house though...
and thrown quickly back together...
I'll let you know when it's all nice and tidy.

Re: It lives again!
Well, I've sanded a decade's worth of dirt off the body and wheels. Had to "rebuild" the back left pillar because I could fit my hand between the screen and the nearest metal.
I'm off on a work trip for 2 months so the respray will have to wait.
Back together and after a full body sand to remove the dirt.
A good indication of before and after dirt-wise.
