SIKMA

Hi people,

This is one of my cars and its a 1982 GJ Sigma. I drive it as my daily. Has the Astron I 4g54 engine with a 5 speed Jap gearbox. Its got a range of modifications just to name a few;

-Stage 3 crow cam
-double valve springs
-skimmed head, should give around 9:5 compression or more
-twin downdraft solex mikuni carbies
-full 2.5" exhaust

No major plans for it at the moment but later on down the track I want to build a 4g54 with a big supercharger retaining the carburetor configuration. Imo old cars should keep to their generation.

Recently, Ive put in a big sound system using all the spare audio gear in my cupboard and its been well worth it

Hi there,

Im tommy, Ive been a member of sigmagalant.com for awhile since I own a GJ Sigma, but now I have also decided to join 4gtuner

In the past we had a CB lancer but thats long gone now.
The sigma is pretty worked and is running a rough cam, twin solex mikuni downdraft carbies, skimmed head for high comp, double valve springs, 2.5" exhaust and heaps more.
Goes hard for an old school car and a pleasure to listen to when you put the foot to the floor because carbies scream

Cheers, Tommy
