PROJECT V6 SIGMA (NOW PROJECT V8 SIGMA)

[cozer82]

Maybe i cant remember see so many tuff cars there all the time and i remember when he was doing ur sigma i remember seeing it there......small world!!!

[ISKA8]

haha u seen my baby there...yeah his done all my cars even my ss..it is a small world isnt it..

[cozer82]

Heys guys another update......the boot is now done, i cut the floor out to remove spare wheel well and redone floor.....i hope all this helps some one because i had a hard time finding pics and info on doing this v6 conversion so im putting a heap a pics up to help someone in the future so i can pass on the info i couldnt find....
original boot

boot with new floor and fuel cell

new boot finished with fuel cell/nitrous bottle just gotta put the other nitrous bottle in on other side

[cozer82]

Another update.......the engine is in i am getting very excited now, the engine went in much easier then i thought sits in the engine bay nice with a heap of room even the passenger side extractor fits in!!!!! Now i just need to finish the fuel system and a couple of small things like get the exhaust and the tailshaft done and finish up the wiring......

[ISKA8]

F@#K THAT THING IS LOOKIN AWSOME MATE,motor looks right at home!

[cozer82]

thanks mate im happy with how its turning out everthing i have pictured in my head in coming together......cant wait to tear some tyres off it

[77galantv6]

what have you got done to the motor? anything?
nice and fast progress.
coming along nicely

[cozer82]

Yeah it is going good not bad for only a month work....(hard work) the motor is stock just was rebuilt bout 6 burnout comps ago so its been well used i had a motor with nitrous cam and head work before but it seems to be better left standard and in this sigma with only the 75hp shot of nitrous will be more then enough to sit in top gear on the limiter but once the conversion is all sorted out i may drop in the supercharged v6 which at the moment we a trying in another car also running nitrous and 17psi boost upgrade.....then this sigma will be fun but that is for the future....

[cozer82]

Just another update.........fuel system is completed, got the vs v6 radiator to fit will upgrade with a alloy vn v8 radiator later on, all the wiring is completed with battery in boot all under dash wiring is done just havent hit the kit yet.......waiting on the tailshaft to be made at the moment and car is now out of the garage at my mates shop EXHAUST BROS gettinng the exhaust done also getting some plates welded into the body and the rear control arms welded up......not long now not bad for 2 months work.........and also DONT and i mean DONT buy anything from V6 CONVERSIONS they are useless and full of shit!!!!! Crossmember still didnt fit i had to modify it
the engine bay finished

no power steering(THANK GOD i blow a pump every burnout comp)

how the shifter will fit once i get it back

the commodore radiator.....this car was made for v6

gave it a wash before i got to exhaust shop

what a sleeper how would think whats under the bonnet

[cozer82]

Exhaust is finished its and dual 2 an ahalf inch system dumping just in front of the tyres to blow the smoke out but far enough in so you cant see it and a small dummy tail pipe at rear to keep up the sleeper look!!!!, tailshaft is finished and bolted up fits nice and also the diff has been welded hope standard diff last for now.....(will have some more pics up soon)

[milotan]

Did you have to modify the transmission tunnel to fit the auto
gearbox in?

[cozer82]

Had to only tap the drivers side in a little bit because didnt clear the side servo of the auto, just tapped it in abit with hammer....i heard it needed alot of modifying in the tunnel before i started but just dropped straight in

[cozer82]

the sigma is nearly finished put the fuel pump and lines in and turned the key.....only problem i had was commodore ignition barrel wasnt earthed to the colum....after a short sandpaper fixed that problem hit the key again and it started and idle prefect exhaust sounds crazy...looks like i got it all right just gotta finish shifter and ready to drive and smash some tyres!!!!!

When you put a diff in, you might be able to squeeze a early commodore diff in without shortening it(im sure they are the narrower ones, vl maybe)... the sigma rear ends are wider than you think, just depends on what tyres an rims you want to fit.

[cozer82]

yeah sweet ill look into that thanks i have a spooled vl diff and a spool vn diff but havent bothered to do measurments yet i hope so.....

[cozer82]

Just drove the sigma down the street for the first time.....feels funny to drive with the noise it makes sounds crazy...hit the throttle and it lit the tyres up no worrys and still no nos yet it is going to be crazy hopefully race it just after christmas and hope to try it out on the burnout pad at heathcote cant wait....will put vids up as soon as i take it out...completly finished in three months not bad for a full conversion

[A112H]

That is amazing for a full conversion, well done mate. Looking forward to seeing the vid

yea man your right the vl's and before have the shorter diffs they got wider in the vn's, i think there around 50-100mm shorter i can get the spec's if ya want

[cozer82]

Yeah thanks mate if you can get the measurements that would be good if its close i start doing conversion....

[HEMI26]

hey man this is wat i found out

VB to VK sedan are 58.75inches wagons are 59.75inches VL are 59.5inches and the vn is 20mm wider each side than the vl

hope this helps dave

[cozer82]

sweet thanks mate is that axle to axle or from where the backing plate bolts up????

[HEMI26]

sorry man cant help ya out wit that 1 you'll have to suss it out

[cozer82]

sweet thanks for the idea ill keep looking into it...

[amgis_obrut]

VL diff is waaaaaaay to wide for a GH

GH diff is 1388mm

VL = 1511mm

[cozer82]

yeah i thouht no matter which way i go it will need to be shortened is that measurement of the GH diff from axle to axle????....i spoke to a couple of guys and they say around 1500 to shorten vn diff and make new axles.....

[amgis_obrut]

is that measurement of the GH diff from axle to axle????....i spoke to a couple of guys and they say around 1500 to shorten vn diff and make new axles.....

yeah from axle to axle

[A112H]

R31 used the same BW centre as VL and many others

R31 LSD measures 1460mm face to face
Series 3 TRX Bluebirds also use the same LS centre and are only 1430
Depending on the offset of the wheels you want to run you might get away with these?

Both these diffs use 29 spline axles and are renouned for strength in little cars.

Just offering another option.

[cozer82]

sweet thanks guys for the ideas and the measurements just have to work out which way ill go.....

[cozer82]

Just thought id put up some more pics as ive had time to do some more to the car.....
some of the gauges fitted(dont like where they are but didnt wana drill into dash pad)

the shifter is all fitted just got to run wires for nitrous

another of interior


Also after boss kit so i can piss off the ugly steering wheel if anyone has one for sale let me know
thanks
