GH Sigma EFI 351 V8

[mstrrab1992]

Middle one looks comfyer

[77galantv6]

go the lightest one.... if your taking shit out you may as well go all the way
and run a stripped interior (but tidy at the same time)

[A112H]

I would choose the one on the right because I hate those "wings" around my head, but safety wise the centre one would be better.

[geezer101]

Middle seat will eventually get on your nerves squeezing in and out of it and the outer bolstering will wear out. For safety, yes it's the best option. But if you want a seat you can live with day to day, take the right seat.

[amgis_obrut]

well after some stuffing around today i only have one choice and thats the middle seat, the other seat is too high meaning if i sit in it with a helmet on my head hits the roof

so chosen seats will now go to trimmers and get covered to match the interior, spewing that i ordered black instead of polished carbon fiber oh well i'll just spray the backs blue lol

[ghuphill]

what are you doing with the stock seats mick?

[amgis_obrut]

not too sure yet Pierre

if i end up parting with them they'll be missing rails and maybe the material

Why would use a crappy microtech on what is otherwise an impressive
Build there are far superior engine management systems that would have
cost not much more

Like ?? a sprint 500 perhaps ? nope didnt have what i needed ! the sport 2000 had what i needed but it was almost $1000 more than the mt

The lt16 is a good unit, the main reason i went with Microtech is when i rang i got to speak to the bloke that was actually building the unit and he could build me exactly what i needed, it had nothing to do with price even though i got the ecu + hand controller, wiring harness, sensors, injector plugs, and postage for $150 more than a sprint 500

Did the extra weight of the v8 effect the steering , more heavier to
Turn and does it effect the braking

[amgis_obrut]

steering is heavier at low speed still pretty light though, my wife has no problems with it

it stops better than a sigma ever did as it has big vented falcon discs

[cozer82]

hey mate just a question for you i am fitting a 308 to my sigma i have stole your engine mount plate idea and i have made that but are you running mounts off the rear of the engine or just the crossmember for the gearbox??? was just wondering if i need extra mounting at the moment wont be excessive power, the engine is a 355 with solid cam and headwork and will run nitrous dont know the power its running yet.....just seeing what your thought are
Thanks

[amgis_obrut]

no mid plate, though its something i may do down the track

[armor117]

what motor was that a 302 or 351 i would love to know

[Scorpma82]

whatever it is...its a cleveland....im guessing 302

[amgis_obrut]

It was a 302

[amgis_obrut]

well its finally back together and off to be tuned on Friday

[amgis_obrut]

had it on the dyno last week for a tune had some troubles with the coils shutting down and not revving over 5000rpm, still made a tad over 300whp so it should be interesting to see what it makes once the coils are sorted and some more rpm
It feels pretty strong when its on the converter !

[75glnt]

MINT! we need a vid

[A112H]

Awesome work Mick, this is my #1 Sigma by a long shot

[amgis_obrut]

some more progress

had to do something with the pod filter so the cops don't get to excited when they decide to have a look

JNT performance have these great pod covers, but fitting it in the bay was going to be tight



It kind of fouled with the wiring, light relays and factory ignition module that occupy that side of the bay, basically I had to get rid of anything that wasn't needed and move the stuff I do need
so the ballast resistor, factory ignition module and most of the wiring was removed and given the flick, then the head light and high beam relays were to the other side of the bay and the wiring changed to suit


Now I have a nice big void free of mess, while I was at it I changed the std brittle light plugs for some porcelain jobbies


Next was to enclose this area, I used 1.5mm aluminium, making these panels was pretty easy to do because I made them from cardboard first then used it as a template
the bottom panel required some welding


There's also a panel that covers this section and tucks in behind the radiator, hopefully it will direct air to where it needs to go


Just needs some paint and that's it !

[amgis_obrut]

just for some added fasts

Hey amgis, I'm guessing the 4th coil fouls on something on the drivers side? Where are you hiding it??

[geezer101]

...err, a 351 powered Sigma needs NOS? Is it really that slow? Still, I like the super clean look of the engine bay - awesome stuff

[amgis_obrut]

You can just see the 4th coil on the rear of the rocker cover in the above pics, but if not heres a closer look

Huh you think its not enough ??
Perhaps something like this is more in order ?

[bruggz351]

Thanks.
Very tidy bay.
Oh, and my opinion, stick with the gas, every como and his falc is force fed.

[Scorpma82]

even still....every bloke in his commo and falc will feel inadequete when this f**ker pulls up next to them!!!!

[Gormzz]

shit is cool.. personally if you were to go force fed i'd stick to the turbo preferably as they just sound so mean! either way this thing would haul with or without forced induction.

[amgis_obrut]

This is how you remove just over 2kg from a GH rear bumper support, I could probably remove close to another kilo
so its gone from 7.3kg down to 5.19kg
