I added the build up last week and it has cost more than what i expected, still I reckon i could run 10's for 10k once the turbo and efi is on

Re: G spec GH
absolutely love driving this thing, its much more than I expected
A v8 is exactly what a sigma needs
Damn you Mitsubishi you could have had a winner if you had just slotted in a V8 like a 318

yes- it would have saved you all that work.A v8 is exactly what a sigma needs

I reckon if the oil crisis in the mid seventies (and again in 1980) weren't so bad, Chrysler Australia would have been in business long enough to include a hemi-6 powered sigma in the line-up- just like they did with the Centura.

Re: G spec GH
Do you notice the weight over the front end Mick?
Do you have to take it easy coming into a corner incase of understeer?
But ill bet its fun coming out of the corners
When does the trick inlet go on?

Re: G spec GH
just read this whole thread. so jelous. wish i trusted myself to build an awesome car. but no knowledge, tools, and space make the sad prescription for a disaster. would cost 3x your cost to get someone else to build me one

Re: G spec GH
maybe your overestimating my capabilities
i would love to do a slow build of something. engineering a car in SA cost 2-2.5 grand alone. purchase the car, fix the body and paint, buy and install engine, make new engine mounts, etc. as you know the list goes on. im only 22 and would describe my mechanical knowledge as quite poor so until i have tools and a garage i think i have to let the dream sleep for a while......

Re: G spec GH
Stage 2 is just about to get underway (i think )
this means i'll be rebuilding the top end porting the heads fitting some quality valve train and installing a nice hyd cam
Then
setting up a coil near plug ignition system sequential fuel injection and a fuel system designed to feed 700hp (not that i'll need it )
first up i'll post some eye candy not that any of this stuff is of any use to most sigma owners
custom EFI manifold
sheet metal rocker covers
CompCams 280h cam, ovate wire valve springs, 10 deg retainers and locks, pro magnum lifters and stainless roller rockers
Rollmaster Billet timing set
Speed Pro hardened push rods
Powerbond Race Balancer, needs to be modified for a 36-1 trigger wheel
Bosch Motorsport 044 fuel pump
Fuel tank sump kit
Cam angle sensor, for sequential injection
Other parts that are on their way
Ls2 truck coils, these things will knock you off your feet
Magnafuel 70 and 25 micron fuel filters
Microtech Lt16 ecu and hand controller
plus lots of other goodies
Im excited about this stage of the build, lots of tricky things to figure out

Was good to see this thing when dad and I picked up that 2L, looks pretty tidy in person
Will be awesome once you're done. Cheaper skids than a turbo Anchortron, that's for sure

Re: G spec GH
im not really chasing power at the moment though im looking at conservative 350-370hp at the engine , cam is pretty tame and comp is only 9.5, bottom end is all factory 1973 and the factory needs to be replaced77galantv6 wrote:definite win. love the sheet metal covers.

its more a base to sort out the injection and ignition, as it wont matter if i get the tune wrong and kill the bottom end once its all sorted i'll build something with more cubes comp and cam

Re: G spec GH
got my fuel filters today, dont get much for a few hundred bucks
dont know why they cost so much though im guessing the element is woven from the pubes of a guardian angel
maybe i should have bought SigmaFuel filters
