What do I have to do to fit a factory turbo set up?

[2Lgalant]

Hey guys just wondering what have I got to do to put a factory turbo set up from a sigma onto a 4g52 and how does it fit into a gb ? Intrested to know and to see pics of peoples engine bays

You will need the Sigma exhaust, the engine and gearbox, a 10mm, 12mm, 14mm and 17mm spanner a pointy nose pair of pliers and a phillips head and flat head screw driver. Remove the rad spacer and a shit load of time a paitence.

So there's not cutting anything I understand I need the sigma exhaust and that and how to put the motor in but does all the manifold fit and that

if you havnt already got it, try get a turbo kit with EVERYTHING. theres nothing worse than having to run around or wait for parts that you dont have or that are missing.

[2Lgalant]

Well I just bought the manifold and the carby off eBay so all I need is turbo and exhaust manifold am I right

nah..... if your putting it on for giggles and dont care how long it goes for maybe. If you want it to work as a minimum (!) youll need a turbo distributor and a drop of compression somehow ( generally that would be new pistons to suit), it will need a reasonable supply of fuel, someone to check the air/fuel ratio . the stock diff will last a while if you are carefull, the first high RPM launch will probbaly be its last. Then there is engineering for rego if thats where your going....

Well engine is going to be rebuilt I know that so it will be to turbo specs , diff will be rebuilt and will be made to withstand turbo power I knew those things so TURBO DISTRIBUTER what do you mean by that can I use my original one and get it all tuned or do I need a new one fuel/air it's all done by the carby isn't it it's got a su on it ?

As much help will be grately appreciated as I need it I know nothing bout turbos really know a little but not all that much

[Superscan811]

so TURBO DISTRIBUTER what do you mean by that

NA dizzy has vacuum advance, Forced induction requires Boost retard.
Same thing in theory, but in different pressure areas.

can I use my original one and get it all tuned or do I need a new one

Yes you can but they have to change quite a bit and, yours would probably require a rebuild as well.
Look on Ebay for the US Starion/Conquest dizzy

Cheers.

Ok then so a starion dizzy is the way to go. So what do you guys reacon I show use internally in my motor I.e what pistons, what cam, what bearings as I will do as much as I can myself I've already striped the motor and will put the new pistons in and stuff but will leave the head work for the pro's

[A112H]

Needs to be an American Starion, they called them Conquest, as they use a turbo'd 4G54 Astron. Local Starions used a SOHC 4G63, the dizzy out of one of these will be no good.

[2Lgalant]

Oh ok then that's understandable

@jason, won't a sigma efi dizzy work as well? or?

[Torana68]

only if its a Turbo 4G5 one?
