Looking at buying a Red GN manual sigma. Has 165,000kms. Is a two owner beast with grey interior, it looks mint inside. Paint is faded. Completely stock. Hasn't been run in a whole and has fuel issues. Will start with start ya bastard, but won't idle. Scott (superscan011) thinks it may be blocked fu...

G'day Superscan, yes I am completely confused as to what injectors to use, I was thinking Bosch 850's with the same impedance as the factory injectors. Though I will have to speak with someone over the phone so I can get some reassurance. I think I'm going to go with a MegaSquirt II and wideband. If...

Yes Scorpma82 I'm aware they all ran the 4g54b. They had shit heads and prehistoric injection just like the JB on the Australian market. They did have flat panel Starions also, but again, anything delivered to the American shores, had the 4G54 heart beat. My question is not regarding anything to do ...

Hey Phil. Heard about your beast over there, do you have a write up on it? Ah I was hoping they were big enough. What's the size you think I would be looking at? I'll be running max 30psi through a GT3582. Most likely have my high setting at 28psi for the track. Waiting on my turbo manifold from Ron...

Thanks guys!! It's actually for a Starion. My GF's ride will be an NA EFI 4G54. So I'll be using extractors on hers. Unsure if there would be anyone that has a NA Starion in 4G54 form. I'm Unsure of the room compared to a sigma under the bonnet. I was hoping to get a pair bolted on without drama, as...

Just a simple question as I have no idea myself.

Will the Triton or Sigma 4G54 extractors fit a Magna M7 head?

Yeah Astronturbo77 they do come stock with both engines indeed. I'm more curious as to who has swapped out the 4G63sohc in favour of the sigma engine swap. I'll be using the standard Starion box from the Australian delivered 4G63. Plenty of wide body imports floating about in aust, though it seems n...

How many people out there have done the swap? I'm doing the swap very soon. Have everything ready to start the build, minus the engine. Have had to pay another guy for second hand motor. Haven't decided on what pistons to run yet, will be running 18psi tune and 30psi tune with GT3582r on E85 only. H...

Redzone do you have access to JD WHEELS??

Yes I own a JB Gun metal grey. Stock 2.0 sohc coming out, being replaced with sigma 4G54, magna M7 ported head, JDLauto design custom twin scroll manifold, ( work of art ) the manifold, highly recommend them. GT 3582r turbo, twin 38mm Tial waste gates, custom fuel rail with Bosch 850cc injectors, tw...
