PROJECT V6 SIGMA (NOW PROJECT V8 SIGMA)

[cozer82]

Hey guys just wanted put up some pics as i go along with this build, i will be converting a gh sigma to vs commodore v6 engine running nitrous engine package runs good in my burnout car at the moment but getting sick of commodores and dats why i got the sigma, i will post more pics as the build comes along......

This is what im starting with......



So far the build begins.......

[75wagon]

That car looks like it was a pretty tidy one before you started?
Is this one going to be a burnout car too?
Is the TE Cortina wagon in the background your old burnout car?

Dave...

[cozer82]

yeah will be a burnout car/drag car but i will trying to not destroy this one!!!!, sigma is very tidy paint and interior pretty much perfect it was a one owner got it off a old bloke and the car had full service history with stamped service book only 194000 genuine kms, was thinking of selling it but dont think ill find another at the price i got it for in such good condition........the TE wagon is my mates car it has seen a few burnout comps aswell as the marks on the side show

why not a lexcen v8 same size of the v6 more reliable
hate the v6 conversion cos i hate holdern motors
they always break ,dosnt mater wat you do to them

I would have to agree, but if you have lemons...

Well i think different i have run a vt v6(ecotech) in my vs for 2 years have done prob 10 burnout comps and i hold this thing in top gear on the rev limiter for around 2mins at a time sometime longer while using nitrous (running 100hp shot) , i have heat seized this engine three times and still runs fine if thats not a strong engine den i dont know what is!!!!

The V6 is a Buick engine.

[brendon]

I too have an ecotec going in my sigma and not a huge fan of that motor
i would have preferred the 1ufze but couldn't justify the extra expense when the ecotec conversion is an off the shelf buy.

Parts for that motor are as cheap as chips and available in every wreckers where bogans reside ... Australia wide

[cozer82]

Have you started putting the engine in yet??? Ill be getting my mounts this week

[7thsin]

funny stuff ,
i dont care wat any one thinks , each to there own but holden motor,s are a ticking time bomb the only good indestructible motors are the 202 or the 186 lol , but why do u think so many are in the wreckers 4 ?, i have seen VPs VS VR VP VT on ebay 4 sale 4 200 bucks or 600 or ORO lol , one thing they all have in common engine dose not start common commahore problem ,a fine example my mate got one 4 1500$ thou another mate of mine bad mistake, VS commy fine body expt the engine ,worked fine 4 a few days till the engine started making this knocking sound guessing it was a engine bearing ether way car cant go 1 block with out making a deafing knocking sound , now its sitting at the shop the guy wants 1 grand just to work on it i wouldn't blame him , and as for the seris 2 engine in the vt , it is alright motor as long as you knw it hasnt been thrashed them motors are getting old now , m8 had one chiped nice exhaust system ,and lowered springs went like the clappers ,also the super charged model pretty quick to but sucks alot of petrel thou..point bean every early late 80s to late 90s holdens i have seen have had problems . half the time cheap to fix but id rather reliability ..

[cozer82]

Being a mechanic and engine builder building v6s with big horsepower for last 7 years and using dem for burnout comps have seen some strong v6 engines compared to alot of other engines I've seen not take the punishment I think u an ur mAtes have just had bad luck with the v6.... but knowing bout cars and engines helps alot when buyin or building one I must admit I have blown a heap up but I've distroyed them never blown one driving to milkbar!!!!

[cozer82]

Plus this isn't a debate on the v6 engine dats for the commodore forum!!!!!

[brendon]

Have you started putting the engine in yet??? Ill be getting my mounts this week

no a month or so off.... i have a make a range rover reliable first so I've got a daily driver.
I have everything ready to go, but then realised I'd need to have another form of transport whilst this build takes place cause its not just drop the motor in, I'm going to try and graft a commo steering rack in it and narrowed commo diff.

[cozer82]

Sweet I hope to have my engine by next months why do you just keep the steering box as a sigma steering is easy anyway

[brendon]

Chanign to commodore brakes and stud pattern and thought may as well go the whole hog

[cozer82]

true you must be spending alot of cash on it

so what would you consider to be a reliable swap ??

Good mate of mine has a torana with a 308 its making about 650hp n/a and will take a 300hp shot of nitrous

This engine has done heaps of mid 8 second passed in another car getting 300hp shots of nitrous smashed into it run after run after run and it has never failed

saying that all holden engines are ticking time bombs is like saying every Muslim is a suicidal Allah loving terrorist , its just dumb and totally wrong

all std engines are garbage and all have the potential to be extremely good

[cozer82]

Just abit of a update......i got my mounts but the gearbox crossmember was wrong not wide enough to go across gearbox tunnel so i decided to do the miring today........ran all wiring and mounted up the fuse boxes

Next week hopefully get the new gearbox crossmember and put engine in then gota do the fuel system......

[cozer82]

Just sent my crossmember back found out they dont have a crossmember to suit my sigma and had to send the sigma crossmember so they can make one.......you would think a sigma conversion kit will fit a sigma but i seem to have a different body then any other sigma so they tell me they have never seen a cross member like mine!!!!! my december deadline is getting closer.......

[84GKSIG]

cross member different between GH and GJ/GK? surely some one would of converted one of these to a commo v6 before.

M.B

[cozer82]

Yeah you would thinks so and being a v6 specialist selling sigma v6 kits you would think he has researched it abit better but hopfully have my crosmember back this week just last night finished all the wiring under the dash hopefully engine in by next weekend.....

[cozer82]

Just another update guys......before anyone asks why i have done this....i am running complete commodore wiring in sigma and needed the cluster

[Billsy]

haha, nice one.

i assume the commo needs the cluster to run in that case, id have thought you could isolate what ever is inside it and not have to use it

[cozer82]

yeah because its a vs and im using the complete wiring when i had the cluster out of my burnout car it goes into limp mode and i could just pay 600 or so dollars to remove dat and the body control module but its neat and hidden away give the passenger something to watch during the burnout , with the vn commodore you only need a engine light wired up and a alternator light wired up(alternator doesnt charge without complete circuit) but the vs i dont know what it is just hunts for idle and mine didnt shift gears right when it was out so easy to just leave it in and cheaper....

[cozer82]

Just a video of how the vs commodore went on nitrous in the burnouts before i painted it.........the sigma should be nuts!!!
Check it out......

[cozer82]

Hey guys just another update got my crossmember for the gearbox today.....about time!!!! Also got my fuel cell so i can start doing my fuel system i think a few late nights are ahead to get finished for december burnout comp
the crossmember

the fuel cell

[ISKA8]

this car looks to be something crazy,i love it..like the cluster inside the glovebox ,f@#$ cool..
nice to see other people taking interests in BROS EXHAUST in footscray...very good people to deal with and cheap too..
cant wait to see this car go..good luck

[84GKSIG]

shiny new parts are the best sort of parts! funny thing is the dash in the glove box almost looks as if its meant to be there lol cant wait to see this once your all done!

Thanks mate....Exhaust bros have been there to help with the last four cars i have built and Brendon the owner is a good mate of mine ive known for alot of years he is a top guy and does some crazy custom work....he will be building my extractors and exhaust for the sigma i recomend them to anyone dat needs custom work done in melbourne....

[ISKA8]

yeah brendon is my bro's mate,he does alot of work for my his workshop...he actually done my custom turbo manifold for my sig.
have you ever seen him cruising around in a gold xy gs fairmont??its really quick one..
